A 41-year-old longevity doctor says his 'biological age' is 24. He takes 3 supplements daily.

Dr. Mohammed Enayat, the founder of a longevity clinic, says he's reversed his "biological age" by 17 years.
He told Business Insider that supplements are a part of his longevity routine.
He takes B complex and folate, magnesium, and omega-3 fatty acids daily.
Dr. Mohammed Enayat has access to all sorts of experimental antiaging treatments at his clinic, but a core part of his longevity routine is pretty cheap and accessible: supplements.
Enayat told Business Insider that his most recent "biological age" tests, taken 18 months ago, said he was 24, or 17 years younger than his chronological age of 41. There's no consensus on how to define or measure biological age, but Enayat used GlycanAge and TruAge PACE, which measure inflammation and epigenetics, respectively.
The primary care doctor, who's also the founder of London's Hum2n longevity clinic, has been closely tracking his health for the past seven years, using wearable tech, including an Oura ring and a Whoop strap, plus regular blood, urine, and microbiome tests.
Enayat changes his longevity routine, including the supplements he takes, depending on the results. But he has taken what he sees as his "core" supplements, B complex and folate, magnesium, and omega-3 fatty acids, daily in cycles over the past several years, he said.
"While I believe these supplements have supported my biological age reversal, I credit them as one component in a much broader framework," Enayat added.
In general, dietitians recommend that people prioritize getting their nutrients from food and supplementing if they have deficiencies or are unable to eat certain nutritious foods.
Enayat takes a vitamin B complex and folate supplement.
"I have a methylation gene defect, which means that my homocysteine, one of the markers, rises high, which is very pro-inflammatory. So to bring that down, I have to be on a good B complex and a folate supplement," he said.
Having high levels of homocysteine can increase the risk of blood clots, heart attack, and stroke. But you can lower your levels through supplementation and eating foods that contain B vitamins, including fish, poultry, legumes, seeds, eggs, dairy products, and leafy greens.
More broadly, studies have linked B vitamins to better mood and the prevention of dementia, but more research is needed.
"Even without a methylation-related gene defect, I would still consider taking a methylated B complex, particularly during periods of high stress, poor sleep, or intensive training, as these increase the demand for B vitamins," Enayat said.
Magnesium is found in legumes, dark leafy greens, nuts, seeds, and whole grains. It plays a key role in many biological processes, including building strong bones, regulating blood sugar and blood pressure, and muscle function.
Enayat's magnesium is below the recommended level, he said, because he doesn't get enough from his diet. This is relatively uncommon — about 2% of Americans have low magnesium levels. For this, he takes a form of magnesium called bisglycinate because it's easier for the body to absorb. "It works really well to bring my levels up," he said.
When he takes magnesium, he finds that his muscles ache less and he falls asleep more easily.
Omega-3 fatty acids, found in foods including oily fish, walnuts, and chia seeds, have been linked to better heart health, lower inflammation, and lower blood pressure.
Enayat has naturally low levels of omega-3 fatty acids, so he takes a daily supplement. There's strong evidence to suggest that eating fatty fish weekly is protective against cardiovascular disease, but it's unclear whether taking it in supplement form provides the same protection.
There is, however, some evidence to suggest that taking omega-3 supplements may have antiaging effects. A study on 777 participants with an average age of 75, published in the journal Nature Aging earlier this year, found that those who consumed a gram of omega-3s every day had lower "biological ages" than those who didn't.

These are the best – and cheapest – states for seniors living alone

More than one quarter of seniors live alone, according to Census data. And living solo can present financial perils for Americans of any age. A new report from the senior care platform ranks the best states for over-65 Americans who live alone. The report assigned a 1-10 score to each state, based on more than a dozen qualities, including overall living costs, housing costs, grocery costs, transportation costs, healthcare costs and availability, and the proximity of other seniors. 'Living alone can be a challenge for older people, from increased safety concerns to the toll on their mental health,' the report states. Here's what the analysis found. These neighboring states rank 1-2-3 for solo senior living Three middle-of-America states, Arkansas, Missouri and Kansas, rank first, second and third for solo senior living in the report. Arkansas, with a rating of 8.57 out of 10, has one of the lowest cost-of-living scores in the nation, with affordable housing and low property taxes. It ranks high for affordable transportation and available nursing facilities. Missouri (8.09 out of 10) ranks high for health care affordability and quality. The state also ranks high on assisted living, with 97.5 communities per 100,000 senior residents. Kansas (7.98) ranks favorably for overall cost of living and has some of the nation's lowest grocery prices. It also has the second-highest proportion of nursing facilities, 62.7 per 100,000 seniors. Arkansas also ranks 1st in affordability for solo seniors Arkansas is not just the 'best' state for solo seniors, but also the most affordable, the analysis found. Arkansas has the lowest health care costs among states, as well as low grocery prices and affordable rents. A one-bedroom apartment averages $701 a month. Missouri ranks second for senior affordability, with low rents and transportation costs. Oklahoma ranks third in affordability. The analysis includes data from GOBankingRates, whose calculations found Oklahoma one of the most affordable states for retirees. Maine ranks 1st for highest proportion of seniors Seniors can face loneliness and isolation, especially when they live alone. But not, perhaps, in Maine. The state has the highest proportion of seniors, compared with other states: 22.9%, according to Missouri ranks 1st for cheap rent Seniors often live on fixed incomes. Lower housing costs can help make ends meet. Missouri has the nation's most affordable rents for one-bedroom apartments, with an average of $677 a month. Pro tip: St. Louis is more affordable than Kansas City, with rents averaging about $200 lower. Iowa ranks 1st for availability of nursing facilities With a relatively low over-65 population, Iowa ranks first among states for its proportion of nursing facilities, 71 per 100,000 seniors. More nursing facilities potentially means shorter wait times for Iowans who need nursing care. Alaska ranks 1st for availability of assisted living Alaska, too, has relatively few seniors. The state also has the highest proportion of assisted living communities, a whopping 698 per 100,000 over-65 residents. Missouri has the least expensive assisted living The costs of long-term care can be eye-popping. An assisted living facility charges $5,350 a month, on average, according to T. Rowe Price. Missouri has the lowest annual costs for assisted living, averaging just over $40,000, according to The state's low cost of living reduces operating costs for assisted living facilities. West Virginia ranks 1st on 'comfortable' retirement Getting back to GOBankingRates: The personal finance site analyzed every state for annual retirement costs and found West Virginia the most affordable in its 2024 report, with an annual tab of $58,190. The report factored into the ranking. What are the worst states for solo retirement living? While the report doesn't rank the least desirable states for seniors who live alone, the analysis provides a heat map that gives a good idea of which states a cost-conscious senior might want to avoid. Not surprisingly, the 'worst' and least affordable states for solo seniors tend to fall on the East and West coasts. California and Massachusetts have some of the lowest overall scores. The same states rank poorly on affordability. More on affordable states for retirees Seniors who are looking for a good place to retire may also want to consult GOBankingRates, whose analysts have run the numbers many times on affordable states for retirees. In one recent analysis, the site calculated how long a nest egg of $1.5 million would last for a retiree in every state. That report identified five most affordable states for retirees: West Virginia, where $1.5 million will last 54 years; Kansas (52 years); Mississippi (51 years); Oklahoma (also 51 years); and Alabama (50 years). California and Massachusetts ranked among the priciest states for retirees in the report, along with New York, Alaska and Hawaii.

Foods And Drinks That Cause Constipation

Constipation is the most common gastrointestinal complaint, affecting millions of Americans of all ages. Prevalent as it may be, it's an unpleasant issue that you'd probably prefer to avoid. And what you eat can either help or hinder things in the poop department. According to Johns Hopkins Medicine, you're typically considered constipated when you're passing 'small amounts of hard, dry stool, usually fewer than three times a week.' But when it comes to poop frequency, the normal range is pretty wide: anywhere from three times a day to three times a week. So consider what's a deviation from your usual pattern. Constipation is about more than just frequency of bowel movements, though. Other symptoms include pain or difficulty pooping, feeling like you haven't fully emptied your bowels, bloating, sluggishness and stomach discomfort. Most people deal with short-term constipation at one point or another. Chronic constipation, however, is an ongoing issue that can negatively affect your quality of life and lead to complications, like hemorrhoids or fecal impaction, if left untreated. You may become constipated due to dehydration, lack of exercise, changes to your routine (such as travel), stress, certain medications and health conditions such as irritable bowel syndrome. But below, we'll focus on some of the ways your diet could be contributing to your constipation woes. The main takeaway: Foods that are high in fat but low in fiber tend to be the worst offenders. No one specific food or drink is likely to cause constipation on its own for most individuals — however, your daily eating habits can worsen an existing issue, according to Medical News Today. We asked experts — including gastro doctors and dietitians — to explain which foods and drinks you might want to consider cutting back on when you're backed up and why. 'Refined grains like white bread, white pasta and white rice are known to be binding and can contribute to constipation,' registered dietitian Stefani Sassos, nutrition and fitness director for the Good Housekeeping Institute, told HuffPost. 'This is due to the fact that they are lower in fiber than whole grains.' Baked goods such as pastries, cookies and cakes, as well as crackers and flour tortillas fall under this umbrella, as well. With refined grains, the fiber our bodies need to facilitate digestion is stripped away during the milling process. 'Fiber promotes regularity by helping food move through your digestive system,' gastroenterologist Dr. Supriya Rao previously told HuffPost. 'This is because fiber absorbs water and bulks up stools, making them easier to pass.' Dairy products like cheese tend to be high in fat, yet low in fiber, which can make constipation worse, gastroenterologist Dr. Rabia A. De Latour told HuffPost. For those with a lactose intolerance, consuming dairy products typically leads to diarrhea and gas. But according to a 2022 literature review, about 30% of lactose-intolerant individuals experience constipation after eating dairy. Red meat, such as beef and pork, these kinds It is also rich in protein, the most satiating macronutrient. This means you might feel full after eating that steak or burger, making you less likely to reach for high-fiber foods like fruits and veggies. Fried foods French fries, fried chicken, mozzarella sticks and other fried fare can make you more backed up. 'Fried, greasy foods are very high in fat and can be hard for the body to digest, contributing to constipation,' Sassos explained. 'Plus, they often are void of fiber.' For other folks, these kinds of foods may lead to more urgent and looser stools — it really depends on the individual and the other components of their diet. Booze is another one that causes different GI symptoms for different people. For many individuals, a night of drinking leads to soft stool or diarrhea. In other cases, it can have a constipating effect. If you're backed up, Dr. Kenneth Josovitz — a Virginia gastroenterologist with Gastro Health — recommends avoiding alcohol, 'which can cause dehydration and worsen constipation.' So why does alcohol have this effect? Alcohol suppresses the release of vasopressin, a hormone which helps your body hold onto fluids by telling the kidneys to reabsorb water, rather than excrete it. 'That [suppression] is why people will pee more when they drink,' gastroenterologist Dr. Sunana Sohi previously told HuffPost. 'The alcohol is making them pee out all the water in their body, and so they get dehydrated and then constipated because of it.' In addition to cutting back on the aforementioned foods and drinks, try to incorporate more high-fiber foods into your diet to help you stay regular. Women should aim to consume at least 25 grams of fiber a day, De LaTour said. For men, that number is about 38 grams per day. Sassos recommends foods like raspberries, apples and pears with the skin on, lentils, beans, broccoli, leafy greens and nuts. Prunes, known for their laxative properties, can also be a good at-home remedy to try, she said. 'If you're not used to eating prunes and fiber-rich foods, start with one to two prunes per day,' Sassos said. 'You can work your way up to five or six as tolerated. Prune juice can be effective too, especially warm prune juice since warm liquids in general can speed up digestive motility.' When increasing your fiber intake, go about it slowly and be sure to drink enough water, she advised. 'We need adequate hydration to help fiber digest properly in the body,' Sassos said. 'If you don't drink enough water, high-fiber foods may actually constipate you even more.' To ease constipation, you can also try drinking a cup of tea as 'the hot temperature speeds up the motility and the caffeine stimulates the bowels,' Josovitz suggested. Reducing stress and exercising can help get things moving as well, he added. Sassos also emphasized the importance of physical activity in keeping you regular. 'Even a short 10-to 15-minute walk after a meal can help,' she said. The occasional bout of constipation typically resolves on its own with minor lifestyle adjustments. But in other cases, constipation may warrant a visit to your doctor — especially if it's coupled with significant abdominal pain. 'You should seek medical attention if the constipation is new, severe, lasts more than a few weeks, or comes with bleeding, weight loss or weakness,' Josovitz advised.

The Key to Better Sleep Is in Your Gut, Says Gastroenterologist

Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Around 25 million U.S. adults suffer from insomnia. At the same time, more than 3.9 million Americans are taking probiotics, usually for gut health, according to the American Gastroenterological Association (AGA). And gut health could be the key to better sleep. A study published in the journal Engineering examined a specific probiotic strain called Lactobacillus helveticus CCFM1320. This probiotic produces a compound known as SAM (S-adenosylmethionine), which helps regulate the body's internal clock and supports the production of melatonin, a hormone that promotes sleep. The researchers found that this probiotic could significantly improve sleep quality. The Gut as a Second Brain Neuroscientist Dr. Chelsie Rohrscheib, the head of sleep at Wesper, a national home sleep disorder diagnostics company, told Newsweek: "The gut essentially acts as a secondary nervous system and creates and releases many crucial neurotransmitters, such as serotonin, which also help to regulate nervous system activity. "This allows for two-way communication between the gut and the brain, called the gut-brain axis. Healthy gut microbes are essential to keeping the gut healthy and functioning, and there is ample evidence that gut microbiota dysregulation can negatively impact the activity of the gut-brain axis. Because the brain is highly sensitive, this can lead to poor sleep quality." Stock image of a woman taking pills from her nightstand before bed. Stock image of a woman taking pills from her nightstand before bed. Liudmila Chernetska/iStock / Getty Images Plus Is CCFM1320 a Game-Changing Strain? To test the effectiveness of CCFM1320 in humans, scientists from Jiangnan University conducted a four-week study with 60 volunteers who experienced sleep difficulties. Participants were divided into two groups: one received the probiotic, while the other took a placebo. Results showed that those who consumed the probiotic had better sleep scores, lower levels of the stress hormone cortisol, and a healthier balance of gut bacteria. Additionally, the probiotic boosted the expression of genes involved in producing and utilizing SAM, a key factor in sleep and overall health. Strain-Specific Benefits Dr. Michel Bass, a board-certified gastroenterologist and the Founding Medical Director at Oshi Health in Philadelphia, Pennsylvania, emphasized the importance of strain specificity: "Not all probiotics are created equal. This study identified CCFM1320 as uniquely beneficial for sleep quality. This isn't a generic 'take-any-probiotic' situation—it's about strain-level specificity," Bass told Newsweek. "That's where a lot of public messaging needs to evolve. Just like different medications target different conditions, different strains do different things. And this one appears to enhance melatonin synthesis via SAM methylation—a novel pathway." Probiotic Supplements vs. Fermented Foods Stock image of an assortment of fresh vegetables and meats. Stock image of an assortment of fresh vegetables and meats. esilzengin/iStock / Getty Images Plus While fermented foods like yogurt, kimchi, and kefir are beneficial for general gut health, Bass explained that they may not provide targeted probiotic strains at therapeutic levels. "If someone wants to improve things like sleep quality or reduce stress hormones like cortisol, a strong, well-researched supplement—especially one with proven strains like CCFM1320—is usually more effective," he said. "That said, eating fermented foods is still a great daily habit and can complement targeted probiotic supplements." Jason Eastty, owner of Healthspan Longevity in Westborough, Massachusetts, and a nutrition specialist, added that overall good nutrition can combat poor sleep. "Having a nutrient deficiency—like low iron, magnesium, or vitamin D—can throw off your gut microbial balance, leading to poor sleep. Clinical trials have shown that correcting these deficiencies helps microbial diversity and improves sleep efficiency," Eastty said. He also emphasized that a whole-foods diet rich in fiber—from fruits, vegetables, legumes, nuts, seeds, and whole grains—is essential to feeding the "good" bacteria in your gut.
