New Hope for Cognitive Decline: NMN Treatment Shows Promise in Restoring Memory
Low-dose NMN restored cognition by increasing serotonin receptor levels in the hippocampus The compound NP, which is present in dishwashing and laundry detergents, has been prohibited in the European Union due to its hazardous nature. Exposure to high doses of NP can result in reproductive damage and cognitive impairments, primarily affecting estrogen receptors. The extent of NP exposure in individuals outside the European Union remains uncertain, and currently, there are no identified remedies to safeguard cognition for those exposed to high levels of NP.A recent study published in Food and Chemical Toxicology by Liu and colleagues from the South China Agricultural University investigated the effects of NP exposure on rats' learning and memory. The study revealed that treatment with low-dose NMN (nicotinamide mononucleotide) restored cognition by increasing serotonin receptor levels in the hippocampus, a vital region responsible for learning and memory. These findings suggest that NMN may hold the potential in preventing cognitive decline in individuals exposed to high levels of NP.To assess the impact of NMN on cognition following NP exposure, the researchers conducted a passive avoidance test with rats. This test gauged fear-based memory by measuring the rats' latency to enter a darkened compartment, where they had previously received a foot shock. NP exposure significantly reduced the rats' step-through latency, indicating impaired learning and memory. However, when the rats were treated with low-dose NMN alongside NP exposure, their step-through latency durations were restored, indicating improved learning and memory. These results imply that NMN supplementation can help alleviate cognitive impairments caused by NP exposure. Low-dose NMN enhances the abundance of all three serotonin receptor types The study further explored the mechanisms behind NMN's cognitive restoration. The researchers focused on serotonin receptors in the hippocampus and found that NP exposure considerably decreased their levels. Low-dose NMN treatment alongside NP exposure restored the levels of three types of serotonin receptors (5-HTR1A, 5-HTR4, and 5-HTR6), while medium and high NMN doses only restored the abundance of one type (5-HTR1A). These findings indicate that low-dose NMN enhances the abundance of all three serotonin receptor types, thereby contributing to cognition restoration, whereas higher doses primarily impact one type. However, the statistical significance of cognition restoration with higher NMN doses was not established. The study provides support for the notion that low-dose NMN supplementation can restore cognition in rats exposed to NP. Additionally, it was observed that low-dose NMN treatment increased serotonin receptor levels associated with memory formation and retrieval. The precise mechanism by which NMN confers these benefits remains largely unknown, but it may involve sirtuin proteins and their dependence on the longevity-promoting molecule NAD+. Further research is necessary to comprehend the reproductive damage and cognitive impairments caused by NP in humans. NMN exhibits promise in counteracting the detrimental effects of NP, particularly with regard to cognitive function. NMN recommended daily dosage is 250 mg -600 mg. NMN can be obtained at a cost of 1500INR to up to 5000INR for a month's supply, with a recommended daily dosage of 250 mg -600 mg. The successful low-dose treatment of 125 mg/kg observed in the study rats is equivalent to approximately 600 mg per day for a human weighing 165 pounds. To achieve similar cognition-preserving effects in humans, a daily intake of around 500 mg or more of NMN may be required. NMN is also used to increase healthspan and longevity

The Protein Intake Sweet Spot For Maximizing Metabolic Healthspan and Lifespan. Japanese Study Reveals Key Info
Protein Ratio For A Longer Life Did you know that low-protein diets have actually been found to extend the lifespan of rodents? That's got us thinking about potential benefits for us humans too. But reducing protein intake might have its downsides too. We're talking about compromising our overall quality of life here. You see when we don't get enough protein, it can actually worsen age-related muscle loss, which is known as sarcopenia. And trust us, sarcopenia can be a real problem, causing mobility and strength issues that mess with our independence. Not to mention the increased risk of falls and fractures. Ouch! The optimal balance of nutrition for ideal health outcomes may vary across different life stages So, finding the right balance in protein intake becomes crucial. Researchers from the Tokyo Metropolitan Institute of Gerontology in Japan did an intensive study with mice to figure out the optimal protein intake for metabolic health and muscle preservation. Their findings, published in GeroScience, revealed that a protein intake of around 35% was the sweet spot for maintaining the metabolic health of those middle-aged mice.Dr. Yoshitaka Kondo, the lead author, had some interesting insights to share. He said, “The optimal balance of macronutrients for ideal health outcomes may vary across different life stages. Previous studies show the possibility of minimizing age-specific mortality throughout life by changing the ratio of dietary protein to carbohydrates during the approach to old age in mice. However, the amount of protein that should be consumed to maintain metabolic health while approaching old age is still unclear.”The study showed that protein intake didn't have a significant impact on total muscle mass. However, here's the kicker—strength wasn't actually evaluated. So, we can't say for sure if low protein intake leads to sarcopenia in this context. So it’s still a bit of a mystery.Now let's talk about those naughty fat cells in the liver. When they start piling up, it can lead to liver damage and raise the risk of some serious conditions like diabetes, heart attacks, and strokes. Not good news, right? Well, those middle-aged mice in the study had higher levels of liver fat compared to their younger counterparts. But hold your horses, when their protein intake went beyond 25% (in the P25, P35, and P45 groups), boom! The liver fat took a nosedive. So, it seems like a moderate amount of protein can keep that liver fat buildup in check, especially when we hit middle age. The magic number seems to be 35% for reducing blood glucose levels. And let's not forget about blood glucose levels, the troublemakers behind diabetes, and other nasty stuff. The study uncovered something interesting—middle-aged mice actually had lower blood glucose levels than their younger pals. And here's the kicker again, a protein intake of 35% resulted in even lower blood glucose levels compared to levels below 35%. But hey, don't go crazy with the protein party because a protein intake of 45% seemed to raise those blood glucose levels. So, the magic number here seems to be 35% for reducing blood glucose levels.Now, we can't ignore those pesky free fatty acids that mess with our insulin resistance and contribute to high blood glucose levels. You guessed it, those middle-aged mice had higher levels of those bad boys floating around compared to the youngsters. A protein intake of 45% seemed to boost those levels even more. So, when we consider all the evidence, it looks like a protein intake level of around 35% is the ticket to optimize liver fat content, blood glucose, and those naughty free fatty acids.To sum it all up, the findings from Dr. Kondo and the gang suggest that a protein intake of roughly 35% can work wonders for our metabolic health and put the brakes on metabolic aging. Since metabolic issues are linked to some seriously nasty diseases, it's safe to say that chowing down on moderate amounts of protein might just extend our precious time on this planet. We still don't have the full scoop on how protein intake affects muscle strength and that sarcopenia thing. So, let's keep our eyes peeled for more research to figure out the ideal protein intake for different age groups.Dr. Kondo has some words of wisdom for us too. He says, “Protein requirements change through the course of life, being higher in younger reproductive mice, reducing through middle age, and rising again in older mice as protein efficiency declines. The same pattern is likely to be observed in humans. Therefore, it could be assumed that increasing daily protein intake in meals could promote metabolic health of people. Moreover, ideal dietary macronutrient balance at each life stage could also extend health span.” How to optimize macronutrients? And here's the fun part—the percentage of protein intake is determined by our total caloric intake. So, let's say we're rocking a 1,700-calorie diet. Our protein intake would be around 23.5% (yup, it's all about dividing [1,700 total calories / 800 calories from protein] x 100). Now, to figure out your daily protein, fat, and carb intake, you've got to keep track of those grams for every bite you take. It can be a bit of a chore, but fear not! There are nifty smartphone apps like My Fitness Pal that make the whole process a breeze.So, there you have it—protein, fats, carbs, and a dash of science to keep us informed about the magical world of longevity. Stay healthy and rock that well-balanced plate, folks!

NMN Improves Diabetes-Induced Male Infertility, New Study Suggests
By the year 2045, approximately 10% of the world's population is alarmingly estimated to have type II diabetes. Men with diabetes often have fertility problems, including reduced sex drive, difficulty getting erections, and abnormal sperm. While some medications like pioglitazone and metformin have shown potential in improving sperm function, better treatments are needed to address male infertility in diabetic individuals. A study conducted by researchers from the University of South China found that giving diabetic male mice a substance called nicotinamide mononucleotide (NMN) improved the structure and function of their testes, leading to more healthy and viable sperm. The researchers observed that NMN also restored the size of the tubes in the testes responsible for creating sperm and increased the number of essential enzymes involved in using glucose for energy, which improved the overall health of the testes. These findings suggest that NMN could potentially reverse male infertility caused by diabetes. NMN Counteracts Diabetes-Linked Testicular Dysfunction During the study, the researchers induced diabetes in mice using a drug called streptozotocin, which led to a significant reduction in the number of sperm and an increase in the proportion of abnormal sperm. However, when the mice received NMN treatment, these negative effects were reversed, with the sperm count returning to normal and the amount of abnormal sperm decreasing. To further understand NMN's impact on the testes, the researchers examined the size of specific structures called seminiferous tubules, where sperm precursor cells are made. The mice with diabetes had smaller seminiferous tubules compared to the ones without diabetes. When given NMN, those tubules bounced back to a healthier size. It looks like NMN might be onto something here in reversing the effects of diabetes on these important structures. This suggests that NMN's ability to improve the structure of the testes could potentially reverse infertility caused by diabetes. Type II diabetes affects the way the body uses glucose for energy. To investigate how NMN might be working, the researchers looked at the levels of important enzymes involved in this process in the testes of diabetic mice. They found that the enzyme levels were significantly reduced due to diabetes, but when NMN was given, they increased again. This suggests that NMN may help the testes use glucose properly, providing the energy needed for producing sperm and potentially reversing infertility. The Diabetic Problem in India India is grappling with a significant diabetes problem, with approximately 77 million people already diagnosed with the condition. In 2020 alone, around 700,000 Indians lost their lives due to diabetes and its complications. Shockingly, this number is expected to skyrocket to a staggering 134 million diabetes cases in India by the year 2045. The increase in diabetes cases can be directly linked to various changes in the environment and lifestyle. Urbanization has brought about significant shifts in how people live and eat, leading to unhealthy dietary habits and a rise in obesity rates. To make matters worse, there's a surge in the accumulation of visceral fat, which poses additional health risks. Research indicates that Indians have a higher tendency for insulin resistance, a condition where the body doesn't respond well to insulin, increasing the risk of diabetes. All these factors combined make Indians more susceptible to developing diabetes, creating a challenging health crisis in the country. Overcoming Diabetes-Related Male Infertility Medications like pioglitazone and metformin may help restore fertility in men with diabetes by improving glucose usage in the testes. The study's findings suggest that NMN could offer another potential solution for restoring male fertility in diabetic individuals. Further research should compare the effectiveness of pioglitazone, metformin, and NMN in this regard. Adopting healthier eating habits and regular exercise can also help counter the effects of diabetes and possibly restore male fertility. The discovery that NMN might restore fertility in diabetic men brings hope for those of reproductive age, giving them the possibility of having children in the future.

NMN Supplementation Upgraded: Exploring the Benefits of Liposomal Delivery
Should you take liposomal NMN? When it comes to NMN supplements, some forms may be more effective than others. Capsules, for instance, are believed to be less effective compared to sublingual powder, lozenges, or acid-resistant capsules. The reason for this is it all comes down to stomach acid wreaking havoc on NMN before it can do its magic in the bloodstream, where it's meant to work wonders on your cells and tissues. Now, let's talk liposomes, those cool, tiny bubbles with a mission. Picture them as molecular superheroes, zooming through your body to deliver drugs and compounds like sulforaphane, vitamin C, and glutathione. However, we are still uncertain whether liposomes are necessary for NMN to provide optimal benefits to human health. We're still in the dark on that one, waiting for science to shed some light. What are liposomes? Liposomes can be described as tiny bubbles with a unique molecular structure that act as vehicles for transporting drugs and compounds into the body. They consist of a double layer of fat-based compounds called phospholipids, resembling our cell membranes. The inner part of the liposome is water-based, while the double-layered structure shields the enclosed compound during its journey through the digestive tract and bloodstream. Once the liposome reaches our cells, it merges with the cell membrane, releasing nutrients. Turns out, liposomes are born from lipids, the cool kids on the molecular block. Think triglycerides, fatty acids, and cholesterol. They're the VIPs behind the scenes, ensuring our cellular membranes are top-notch in structure and function. The human gastrointestinal tract poses challenges with its acidic conditions that can degrade nutrients. Now, let's face the harsh reality of our gastrointestinal tract—it's a battlefield of acidic conditions that can obliterate nutrients. That's where liposomal delivery struts its stuff, giving a masterclass in efficiency. These tiny warriors are small in size, and armed with hydrophobic and hydrophilic powers, making them an unstoppable force when it comes to delivering the goods. Is Liposomal NMN better for you? Liposomes have been in the scientific spotlight since the '70s, but it wasn't until the '90s that they truly came into their own. These days, they're the darlings of drug delivery, with the potential to change the game. Presently, there is no definitive evidence indicating that liposomal NMN is superior to other forms. However, a study discovered that vitamin C has better bioavailability when delivered via liposomes compared to its naked counterpart. Could the same be true for other compounds? That's the burning question - is liposomal NMN the holy grail? Dr. Christopher Spade, an expert on liposomal delivery systems, suggests that liposomes mimic the natural cell-to-cell exchange of NMN, which could enhance absorption. However, such a claim lacks supporting scientific research. While liposomal NMN may offer improved absorption compared to capsules, it may have similar effects to sublingual or acid-resistant capsules. Moreover, it's important to note that liposomal NMN in liquid or gel form would be ineffective due to NMN's degradation in water. Hence, liposomes need to be encapsulated for effective delivery. As it stands, liposomal NMN may enhance absorption, but conclusive clinical research is lacking. Sublingual NMN or acid-resistant capsules could be equally effective alternatives. It is also worth considering other forms of NMN supplementation. According to Dr. Spade, liposomal NMN provides faster and more efficient absorption by avoiding degradation in the gut. It boasts several benefits, such as high bioavailability, noninvasiveness, protection against the digestive tract environment, increased oral uptake, intracellular delivery, compatibility with hydrophilic and hydrophobic compounds, and adjustable dosing. The jury is still out there on Liposomal NMN Liposomal NMN might be the superhero absorption champion, but we're still waiting for those research superheroes to swoop in and confirm it. Sublingual NMN and delayed-release gastric capsules might just be standing shoulder-to-shoulder, ready to enhance bioavailability by sidestepping stomach acidity. The world of NMN supplements is a wild one, with liposomes strutting their stuff, but plenty of other forms vying for the spotlight. Let's keep our eyes peeled for more evidence-based research because when it comes to boosting those NAD+ levels, we need the real deal.

Boosting Immune Power: NMN's Potential in Fighting Hepatitis B in India
NMN treatment significantly increases the expression of antiviral cytokines Hepatitis B is a viral infection that tends to be more prevalent in sub-Saharan Africa and East Asia, but it has also made its presence known in India, affecting a terribly significant number of around 40 million individuals, roughly 3% to 4.2% of the population. India falls within the range of countries with moderate hepatitis B cases globally, with a prevalence rate of 2% to 4%. Given India's large population, this poses a significant health concern, adding to the global burden of the disease. Disturbingly, 15% to 25% of people with chronic hepatitis B in India face serious complications such as liver cirrhosis, liver cancer, and an increased risk of premature mortality. While most cases of hepatitis B resolve within six months, some persist and become chronic troublemakers. This occurs when CD8 T cells, the heroic virus-fighting immune cells, become exhausted from their relentless battle. Their exhaustion leads to DNA damage and weakens their ability to combat the virus. Understanding the reasons behind CD8 T cell exhaustion is crucial for developing improved treatments for chronic hepatitis B. Some researchers suggest that NAD+, a substance naturally present in the body, may play a role in this exhaustion process. Excitingly, a recent study by Fisicaro et al. from the University of Parma in Italy, published in the Journal of Hepatology, introduces a potential treatment approach for chronic hepatitis B. The researchers discovered that by targeting specific CD8 T cells that combat the hepatitis B virus with a substance called nicotinamide mononucleotide (NMN), they could give these cells a much-needed power boost. Exhausted hepatitis B-specific CD8 T cells were found to have higher levels of DNA damage and impaired DNA repair mechanisms. However, NMN or inhibitors of the CD38 enzyme have the potential to rejuvenate these exhausted T cells, enabling them to mount a formidable defense against hepatitis B and even other virulent infections. (Montali et al., 2023 | Journal of Hepatology) NMN restores immune cell antiviral cytokine production. Cellular cytokines listed on the X-axis significantly increased following immune cell treatment with NMN and hepatitis B viral proteins (black bars) compared to those treated with hepatitis B viral proteins alone (gray bars). Med + Pep= Cell culture medium with viral peptide stimulation; Med + Pep + NMN= Cell culture medium with viral peptide stimulation and NMN Furthermore, the study revealed that replenishing NAD+ levels in CD8 T cells isolated from chronic hepatitis B patients through NMN treatment significantly increased the expression of antiviral cytokines, particularly interferon-gamma (IFN-γ), which experienced a remarkable 2.7-fold increase. This suggests that NMN holds promise in restoring the antiviral properties of CD8 T cells. (Montali et al., 2023 | Journal of Hepatology) Hepatitis B-specific CD8 T cells have high levels of DNA damage and a weak DNA damage response to a DNA damaging molecule (etoposide). Left) Compared to FLU-specific CD8 T cells (FLU HEALTHY), those specific for hepatitis B (HBV CHRONIC) exhibit higher levels of markers for DNA damage (phosphoH2AX). Right) A molecule used to induce DNA damage (etoposide) elicits a trend toward lower DNA damage response in hepatitis B-specific immune cells (HBV CHRONIC) compared to FLU-specific immune cells (FLU HEALTHY), suggesting lower NAD+ required for DNA repair.In an intriguing comparison between hepatitis B-specific T cells and influenza-specific T cells, the study observed much higher levels of DNA damage in the former group. Additionally, when exposed to a substance inducing DNA damage, hepatitis B-specific T cells exhibited a weaker response compared to influenza-specific T cells. These findings indicate that the diminished NAD+ levels are associated with increased DNA damage in exhausted hepatitis B-specific CD8 T cells, as DNA damage responses heavily rely on NAD+ availability. (Montali et al., 2023 | Journal of Hepatology) Higher immune cell CD38 enzyme levels are associated with lower antiviral cytokine levels. Higher percentages of immune cells with elevated CD38 (%CD38hi) are associated with a lower probability of expressing the antiviral cytokine IFN-𝛾 (%IFN-𝛾+).“Our data show increased DNA damage with limited activation of the DNA repair machinery in [hepatitis B virus]-specific CD8 T cells from [chronic hepatitis B] patients,” say Fisicaro and colleagues. “This strongly suggests that NAD-consuming enzymes, particularly overexpressed CD38, may play a pivotal role in NAD depletion. Reconstitution of many interconnected intracellular functions by NMN supplementation indicates that NAD depletion likely represents an important determinant of T cell exhaustion.” Higher CD38 enzyme levels can impede the production of antiviral cytokines. Moreover, the study found a correlation between elevated levels of the NAD+-consuming enzyme CD38 and reduced levels of IFN-γ, a vital cytokine involved in antiviral defense. This suggests that higher CD38 enzyme levels can impede the production of antiviral cytokines, supporting the hypothesis that low NAD+ levels contribute to the development of chronic hepatitis B, as increased CD38 levels theoretically deplete cellular NAD+.To sum it up, this study provides compelling evidence that the hepatitis B virus triggers the activation of the CD38 enzyme, resulting in a shortage of NAD+. Consequently, exhausted hepatitis B-specific T cells suffer from increased DNA damage, accompanied by compromised DNA repair mechanisms. NMN could play a vital role in empowering immune cells However, there is a silver lining. Treating CD8 T cells with NMN, a precursor to NAD+, has yielded promising results in reviving the production of antiviral cytokines. This suggests that replenishing NAD+ levels rejuvenates the functionality of these T cells. These findings lend support to the idea that NAD+ depletion contributes to the exhaustion and dysfunction of CD8 T cells. Further research is needed to determine if NMN can restore exhausted T cells in the context of other infections. Should NMN prove effective in treating various infections, it could indicate that NAD+ plays a vital role in empowering immune cells to combat a wide range of infectious diseases.

Trying To Get Pregnant? NMN Increases Maternal Egg Quality, Numbers, & Improves Fertilization
The Ovary is the first to fail in Mammals! - Dr. David SinclairThe ticking clock of maternal age and its impact on fertility poses a significant concern for family planning in India. As women journey through the years, their fertility takes a nosedive, especially after hitting the milestone of 30. The culprit? Declining oocyte quality, those precious little cells vital for a successful pregnancy. Here's the harsh truth: We currently lack effective strategies to preserve or rejuvenate oocyte quality as women age. Consequently, there's been an upsurge in the demand for assisted reproduction technologies like in vitro fertilization (IVF) to combat the hurdles presented by this age-related decline.Unlike other tissues that can bounce back through self-renewal, oocytes in the ovary are like a finite resource, established during fetal development and not replenishing themselves. They're sitting ducks for dysfunction as the years roll by.The decline in oocyte quality as the years pile up is influenced by an array of molecular factors. We're talking genome instability, dwindling energy production in mitochondria, pesky reactive oxygen species (ROS), and even mishaps during chromosome segregation in the meiotic process. But here's the kicker: We're still in the dark about the exact cause of these chromosome mis-segregations in aging oocytes. And sadly, we currently lack any pharmacological approaches to tackle this problem head-on. If we could unravel the underlying molecular and metabolic mechanisms, it just might pave the way for therapies that can keep female fertility intact as time marches on.Now, let's talk metabolic mojo. Meet nicotinamide adenine dinucleotide (NAD+), a powerhouse molecule responsible for energy metabolism, DNA repair, and epigenetic regulation. Here's the bummer: NAD+ levels take a nosedive as we age, causing ripples of interest in the use of metabolic precursors like nicotinamide mononucleotide (NMN) to kickstart a revival and keep our bodies rocking well into the golden years. NMN Improves Occyte Quality & Fertility In a quest to understand the fate of NAD+ in aging oocytes and its implications for infertility and oocyte quality, a team of scientists at the University of Queensland embarked on an experiment. They turned to our trusty mouse pals, who happen to experience similar oocyte aging woes as us humans. These researchers gave 12-month-old female mice a four-week treatment with NMN Supplements, and guess what? NAD+ levels in their oocytes shot up, resulting in improved oocyte quality, increased ovulation rates, and heightened fertility. As if that weren't enough, when they added NMN to the culture media surrounding embryos, the negative effects of age on embryo development reversed course. NMN treatment can be a non-invasive method to improve fertility. Hold on tight, because these findings pack a punch when it comes to addressing age-related infertility. The resurrection of NAD+ levels through NMN treatment could open a non-invasive and doable avenue for improving oocyte quality and amplifying the chances of natural conception or success rates in IVF. Picture this: Women with lackluster oocyte quality may be able to conceive using their own genetic material, waving goodbye to the reliance on donor oocytes. But, and it's a big but, we must exercise caution until further clinical studies validate the efficacy and safety of NAD+-raising supplements. Imagine the ripple effect of such interventions—savings on costs, diminished emotional stress from the heartache of failed IVF attempts, and the anguish of infertility. It's a lifeline that could alleviate the long-term psychological and social burdens, including the lurking shadows of depression and relationship strain, faced by those embroiled in fertility challenges.To sum it all up, this study's findings breathe hope into the realm of pharmacological interventions for age-related decline in oocyte quality. The potential is immense—improving fertility outcomes, enhancing embryo development in IVF, and bestowing women with the chance to have children using their own genetic blueprint. However, let's tread lightly until further clinical studies march forward to validate the efficacy and safety of these NAD+-raising supplements.

Memory Upgrade: Creatine Can Supercharge Your Cognitive Abilities
One of the world's most used supplement: Creatine You probably know that creatine is a popular supplement for boosting physical performance and strength during workouts. But it's not just about big muscles and brawn—it has some pretty cool benefits for your brain, seemingly, when it comes to improving your memory.Let's talk about memory. Your brain needs a ton of energy to function at its best, this is where creatine comes in. Think of it as your brain's secret weapon for energy production. It helps your body make this thing called adenosine triphosphate (ATP), which is the ultimate energy molecule that powers your entire system. Sure, there may be ways you can get creatine from your diet, but guess what? Your body also produces it naturally in your liver, kidneys, and brain. So, these clever researchers went on a mission to explore creatine's memory-boosting abilities. They gathered up a bunch of studies and did this thing called a meta-analysis (a fancy term for combining and analyzing multiple studies). And the results were more than pleasantly surprising. When people took creatine supplements, the levels of this magical molecule in their brains went up. And the result? Boom! Improved energy availability and production in the mitochondria—the powerhouse of your cells. Results showed better memory performance compared to those who took the placebo pills. This study encompassed ten trials, including a diverse group of 225 participants from multiple countries such as the United Kingdom, New Zealand, Brazil, and the United States. The participants represented a wide range of ages and included both men and women. The duration of creatine use varied, from just a quick 5-day boost to a longer 24-week period. Most studies used a dosage of 20 grams of creatine, but some tried out lower doses too. Now, to measure memory performance, the researchers pulled out some nifty tools. They gave people tasks like recalling numbers, letters, or block sequences after a bit of memorization. And guess what happened? Across the board, memory performance shot up with the help of creatine. Talk about a memory superpower! Thinking of trying NMN? Read Top 5 NMN Supplements In India: A Brief Review Older participants showed more improvement than younger participants When researchers dug deeper into the data, they made an interesting discovery. Older adults (ages 66-76) experienced some serious memory improvement compared to younger folks (ages 11-31). Who would've thought? While these findings are cool and all, we need to be more chill about creatine. Some of the studies didn't provide enough info on how they randomly assigned people to groups, which could introduce some bias. So, we need more large-scale clinical trials to be sure about creatine's memory-boosting awesomeness and to explore how it affects other aspects of brain health. Previous research suggests that creatine levels tend to decrease as we age. That means if you're starting with lower baseline levels, you might get even more benefits from supplementation. Some other research groups also came to similar conclusions, hinting that older adults or those going through stressful times might find creatine particularly helpful. Creatine supplements have very few side effects & offer a bunch of advantages It's worth mentioning that many of the studies analyzed in this research didn't measure people's baseline creatine levels. So, we still need more investigation to lock in these findings. But hey, here's the good news—creatine supplements usually have very few side effects and offer a bunch of advantages. It's important (and smart!) to consult with your healthcare provider before making any changes to your medication or supplement regimen. They can provide personalized advice and guidance tailored to your specific needs.So! Want to supercharge your brain and body? Give creatine a shot! It could be just the thing you need to level up your memory skills and overall brain health. Stay sharp!

Hitting Centuries: Unlocking The Secrets Of Longevity. Jeanne Calment & Sister André
When considering the lives of the oldest individuals in history, it's natural to wonder how one can increase their chances of living a long life. Take the case of Jeanne Calment, a French woman who lived to the age of 122, surpassing all others. While chance played a role in her longevity, certain aspects of her lifestyle also contributed to her extended lifespan.One significant factor that likely contributed to Calment's long life was her privileged upbringing. Growing up in a prosperous family, she lived in a pleasant neighborhood in southern France. During that era, it was common for women to start attending school at the age of 16. Calment received private lessons in art, cuisine, and dance until she married at the age of 20.Another contributing factor to Calment's longevity was her upper-class status, which meant she never had to work. She always had assistance with cooking and shopping for necessities.Calment refrained from smoking cigarettes until later in life. Smoking was strictly forbidden for girls, particularly those from bourgeois families like hers. Interestingly, Calment only took up smoking at the age of 112 when she resided in a nursing home. An active social life along with other factors can increase lifespan & healthspan Having an active social life was also a part of Calment's lifestyle. She had ample free time to take care of herself, travel across France, and engage in social activities. Social gatherings, such as home-hosted balls, provided her with opportunities to meet new people.Calment had a penchant for travel and had the means to explore the world around her. For instance, she visited the Eiffel Tower while it was still under construction. Living during the transition from the 19th to the 20th century exposed her to a captivating era.France was also home to Sister André, the second-longest living person who reached the age of over 118. Born Lucile Randon in 1904, she grew up in a Catholic family and became a nun at the age of 40, joining the Sisters of Charity of Saint Vincent de Paul in 1944. Throughout her life, Sister André worked as a nurse, particularly caring for the elderly. She remained dedicated to her work until the age of 80.In 2009, Sister André moved into a retirement home in Toulon, France, where she passed away in January 2023 at the age of 118. She was known for her active and engaged lifestyle, enjoying activities such as watching television, listening to music, and receiving visitors. Sister André also had a passion for poetry and had her poems published in French newspapers.Besides these individual cases, France's overall social factors may contribute to longer lifespans. One such factor is the availability of free education. Higher education levels provide individuals with a better understanding of healthy eating habits and appropriate exercise routines, promoting a healthier lifestyle and longer life expectancy. The Average India Diet Has Insufficient Nutrition In contrast, a study conducted in India revealed concerning dietary patterns. The average Indian diet lacked essential food groups, with excessive consumption of processed foods and insufficient intake of fruits, vegetables, and proteins. This pattern was observed across socio-economic levels, including affluent households.Furthermore, a national survey in India showed high prevalence rates of risk factors such as tobacco use, alcohol consumption, physical inactivity, and inadequate fruit and vegetable consumption. The survey also indicated an increased risk of conditions like blood glucose and cardiovascular diseases among participants. Access to Free healthcare can increase Longevity Countries with free healthcare, including France, Japan, and Denmark, tend to have longer life expectancies. Conversely, countries with less affordable healthcare, such as the U.K., the Netherlands, and the United States, have experienced a decrease in life expectancy. The French population also benefits from better dietary choices, with many adhering to the Mediterranean diet. This diet emphasizes fruits, vegetables, whole grains, healthy fats, and seafood while limiting the intake of red meat, dairy, and sweets. In contrast, other countries face issues like excessive fat and salt consumption.In summary, various lifestyle factors contribute to longevity, including socioeconomic status, education, smoking habits, social engagement, travel, and dietary choices. Understanding and adopting these factors can potentially increase one's chances of living a longer and healthier life.
