Best Brain Supplements for Longevity: Boost Memory, Focus & Clarity in 2025
In 2025, brain supplements have taken center stage in the wellness world. From those seeking deep focus to others invested in memory retention, the cognitive enhancement market is booming, with nootropics now a $10+ billion industry and growing. But in a world of overhyped formulas, which ingredients actually support long-term cognitive health?
Here's what the data is starting to support.
Lion's mane mushroom (Hericium erinaceus) is gaining serious attention for its potential to support neurogenesis. Studies suggest it may stimulate nerve growth factor (NGF), a protein essential for the growth and repair of neurons. In one double-blind study, older adults taking lion's mane daily showed statistically significant improvements in cognitive function after just 16 weeks.
It's featured in products by Four Sigmatic and Host Defense, known to reduce anxiety and improve attention, especially when paired with caffeine.
Claims: Promotes neuron regeneration and mental clarity, especially useful in mild memory impairment.
Unlike traditional magnesium, magnesium L-threonate crosses the blood-brain barrier and boosts synaptic density, key for memory and learning. Preclinical trials showed enhanced memory performance and synaptic function in aging animals, with potential implications for human cognitive aging.
Supplements like Neuro-Mag by Life Extension and Thorne's Magnesium L-Threonate offer this in clinically relevant doses. Many users also report better sleep, which directly benefits memory consolidation.
Claims: Supports synaptic function and learning while promoting restorative sleep.
NAD+ (nicotinamide adenine dinucleotide) plays a crucial role in energy production and DNA repair, but levels decline dramatically with age. Research shows that replenishing NAD+ (using precursors like NMN or NR) may improve mitochondrial function, reduce fatigue, and support brain resilience.
Supplements like Tru Niagen and Elysium Basis have been studied for their effects on NAD+ levels, and a growing body of research suggests potential cognitive benefits, including improved cerebral blood flow and cellular repair.
Claims: May protect against age-related brain fatigue by supporting cellular energy.
Omega-3 fatty acids (especially DHA) are essential for brain structure and function. An analysis of 38 studies found that omega-3 supplementation supports cognitive performance in older adults and may delay age-related decline. Top sources include fish like sardines and salmon or vegan options such as Calgee (algae-based DHA) and Nordic Naturals.
Claims: Strengthens brain cell membranes and supports memory and mood regulation.
Beyond lion's mane, mushrooms like reishi, chaga, and turkey tail are being explored for their role in immunity, gut health, and stress response, each a contributor to better cognitive function. These fungi are packed with beta-glucans, antioxidants, and compounds that influence the gut-brain axis, which plays a major role in mood and mental clarity.
Popular blends like MUD\WTR and Laird Superfood's Performance Mushrooms combine multiple varieties with brain-friendly ingredients like coffee fruit extract and L-theanine. If you've also found yourself pausing on those Instagram coffee ads promising a laundry list of brain-boosting benefits and feel compelled to buy, you're not alone.
Claims: Supports cognition, immunity, and stress resilience.
Form matters. Choose liposomal or chelated ingredients for superior absorption. Quality counts. Look for third-party tested, clinically backed brands. Dosing is key. Ensure ingredients are used in research-supported quantities, skip the fairy dust.
Pro Tip: Introduce supplements gradually and consult a healthcare professional, especially if taking medication or managing chronic health conditions.
Brain supplements aren't magic pills — but paired with movement, sleep, hydration, and stress management, they can offer measurable support for cognitive clarity and longevity.

Unlocking Cellular Health With Science and Trust
In the longevity and wellness space, Niagen Bioscience is charting a course defined by both scientific rigor and an unwavering commitment to responsible innovation Niagen Bioscience (NASDAQ: NAGE, formerly Chromadex) is a Los Angeles-based company dedicated to advancing the supplements industry using science-backed research into their component ingredients. At the helm is CEO Robert Fried, who says the company's mission is to pioneer NAD+ research and develop transformative NAD-boosting healthy-aging solutions with Niagen, their patented form of nicotinamide riboside (NR). Niagen is the cornerstone of the company's clinically proven product portfolio, Tru Niagen and Niagen IV and injections. During this year's Cannes Lions, Fried sat down with LA Times Studios to discuss how the company is pioneering the NAD+ space and the science and quality backed benefits of its Niagen products. 'NAD+, or nicotinamide adenine dinucleotide, is a co-enzyme found in all living cells – plant and animal – and is involved in all important metabolic processes within the cell, but especially energy metabolism and DNA repair, which are key to supporting mitochondrial health and overall optimal health.' explained Fried. Mitochondria, the 'battery pack of the cell,' combines nutrients from the food you eat and oxygen with NAD+ to produce energy. NAD+ also plays a crucial role in DNA recovery and cellular repair. 'All of these processes that exist within the cell where the cell repairs damage are NAD+ dependent,' Fried emphasized, illustrating how higher NAD+ levels facilitate rapid healing, contrasting youthful recovery with a slower healing process that occurs as we age. This is because NAD+ starts to decline naturally in our 30s, with research showing a dramatic drop of up to 65% by the time we reach age 70. Exposure to stressors like sedentary lifestyle, excess sun exposure, poor diet and environmental factors also impact NAD+ levels. Research shows that NAD+ decline is associated with a decline in overall health and vitality, contributing to the development of conditions and disease. Fried is quick to address a significant industry misconception: 'NAD+ itself is not bioavailable. If you consume NAD+ orally or with an IV, it will not elevate NAD+ levels inside your cells.' He clarified that the NAD+ molecule is too large to penetrate cells, causing NAD+ supplements and IV to be ineffective. Intact NAD+ may even have the potential to cause acute immune inflammatory response, which may be responsible for the uncomfortable side effects associated with NAD+ IV and injections. The solution, according to Fried, is 'to consume an NAD+ precursor molecule that easily gets into the cell and then converts into NAD+, and the best molecule for this is called nicotinamide riboside or NR.' Niagen is patented NR and precisely what Tru Niagen and pharmaceutical-grade Niagen IV and injections offer. With a legacy spanning over 25 years, the company's recent rebranding from ChromaDex to Niagen Bioscience reflects its sharpened focus. 'We're no longer only a reference standards company but an NAD+ company dedicated to addressing one of life's most complex challenges - aging,' said Fried. Niagen Bioscience differentiates itself by operating as an 'R&D lab that specializes in NAD+,' not simply a supplement distributor, he said. Its distinguished by state-of-the-art laboratories, rigorous scientific and quality protocols, and an external research program helping independent investigators and institutions worldwide uncover the potential of NAD+. 'There is no other company in the supplement space that comes close this level of R&D investment and scientific research,' Fried asserted. The company boasts 38 peer-reviewed, published human clinical studies on oral food-grade Niagen, of which about 95% are completely independent, with another 40 studies currently underway. This level of scientific rigor, he contends, is typically found only in biotech or pharmaceutical companies. Products are tested at the manufacturing facility and then retested upon delivery. Fried notes their marketing: 'We are real. We are genuine. We let the science do the talking.' This approach, he believes, is key to building genuine trust. Niagen Bioscience is exploring Niagen's broader therapeutic potential for its patented NR. Fried reveals extensive clinical studies on the benefits of its patented food-grade NR for specific age-related and orphan diseases (rare conditions characterized by rapid aging). Some of these studies have reached Phase II and III clinical trials. A 52 week, 400-participant, Phase III double-blinded, controlled study on Parkinson's disease recently concluded, conducted with a world-renowned independent researcher. 'That is a level of scientific research ... that you don't see from supplement companies,' Fried emphasized. Niagen Bioscience is also innovating beyond oral supplements. They've developed a pharmaceutical-grade version of nicotinamide riboside, now available as Niagen IV. exclusively at clinics across the U.S. Fried highlighted its advantages: 'If you do an injection or an IV, you're getting the benefits of Niagen directly to the bloodstream.' This results in faster absorption and avoids side effects often associated with direct NAD+ infusions. Fried candidly addresses his concern about a lack of public trust in the dietary supplement industry, citing prevalent unsubstantiated claims, low-quality products, and marketing hype. 'It's my belief that if people genuinely trusted the companies that the industry at large would be so significant because we'd actually have preventative health value,' he states. To combat this, Niagen Bioscience has proposed a 'Trust Alliance' – a coalition of industry players, government and non-profits to test products and ensure claims are met. For Fried, the most meaningful aspect of his journey is receiving letters from individuals who experienced health benefits after taking Tru Niagen. Looking ahead, Niagen Bioscience aims to solidify its position as the 'gold standard in the NAD+ space,' continuing its scientific leadership. 'Our mission is to help every living being around the world age better. We think what could happen in the next five years is very exciting and special,' Fried concluded.

What's Really in Your Kids' Furniture? How to Find Safe, Chemical-Free Pieces for Your Home
LA Times Studios may earn commission from purchases made through our links. Most parents don't plan for their child's first taste of at some point, it happens. A tooth mark on the crib rail, a sticky mouth print on the dresser corner. In that moment, the question isn't just 'will it stain?' but 'is this safe?' As the realities of chemical exposure in kids' rooms come to light, decoding the labels on furniture has become more important. Thanks to mounting research and a new breed of food-safe furniture makers, there's starting to be clarity (and accountability) behind the labels that line showroom floors and pop up in your social feeds. Here's how to cut through the greenwashing, decode certifications, and shop with genuine peace of mind. A recent study put numbers to what every parent fears: more than two dozen phthalates, flame retardants, and other chemicals are hiding in children's bedrooms, not just in old toys but in the beds, nightstands, and even the mattress itself. Under the body heat and weight of a child, chemical emissions spike. Translation: your child's so-called safe space may be a chemical factory, especially if you don't know what's actually in that new furniture purchase. 'This isn't scare-mongering; these are real, measurable exposures, not 'trace' amounts,' says Arin Schultz, Chief Growth Officer at Naturepedic. 'Most people don't realize just how many harmful chemicals they're bringing into their children's bedrooms when they buy conventional furniture. So many pieces are made with glues, adhesives, and synthetic materials that can off-gas for years. It's a hidden issue in the children's furniture industry that deserves much more attention'. 'Non-toxic' and 'eco-friendly' are unregulated terms, says Schultz. 'When we talk about 'food-safe' furniture, we're really talking about finishes, i.e., the coatings and sealants that come in direct contact with kids' skin and mouths,' Schultz explains. 'If your child were to lick the bed rail or nibble on a dresser corner, there wouldn't be any harmful chemicals to worry about with a food-safe product.' Schultz continues that while 'food-safe' does not have a certification that goes with it in terms of furniture, there is a specific testing protocol. 'Food-safe means the finish meets FDA protocols for food-contact surfaces, just like a dinner plate or a spoon would,' Schultz says. 'It's an extra level of reassurance for parents who want to know that what's on the furniture is as safe as what goes in their child's mouth.' Certified food-safe finishes are tasteless, odor-free, and meet or exceed the same requirements as FDA-approved dinnerware. The best examples: solid, responsibly sourced wood, water-based coatings, and adhesives so clean you could, well, lick them. That cute nightstand or bookshelf in your child's room may have more in common with a chemistry set than we'd like to think. Phthalates, used to soften plastics, are known to disrupt hormones and have been well-documented by the CDC for their effects on children's health. Formaldehyde, found in adhesives and engineered woods, is classified as a carcinogen by the EPA and remains a mainstay in the construction of mass-market furniture. Flame retardants, often hailed as lifesaving, have instead been repeatedly linked by NIH studies to developmental and neurological problems. Then there are organic compounds. That 'factory-fresh' smell clinging to new dressers or cribs is more than a novelty. According to the EPA, it's the scent of chemicals evaporating into your child's space. Great. And when furniture warms up, gets heavy use, or starts to wear, the rate of chemical off-gassing gets worse. As Schultz explains, 'Kids are uniquely vulnerable: they breathe faster, their bodies are still developing, and let's be honest, if it's within reach, it's probably going in their mouths.' In a world of splashy marketing, what separates a truly safe product from empty promises? Certifications are where the details matter. If a brand can't offer them, keep shopping. Schultz points to transparency and independent testing as the only meaningful standards. 'If the language feels too broad, it's worth questioning. Also, be wary of prices that seem too good to be true. Solid hardwood furniture with real safety testing costs more to make than mass-produced particleboard with synthetic finishes.' Look for specifics: GREENGUARD® Gold certification means products are tested for hundreds of VOCs. FSC® labels guarantee responsibly sourced wood. MADE SAFE® screens for thousands of potential toxins. Some manufacturers, like Naturepedic, go further by batch testing for lead, phthalates, formaldehyde, and heavy metals. FDA food-contact compliance should never be assumed. Ask directly whether finishes meet the relevant standards. Any reluctance from a manufacturer to disclose these details is your cue to move on. 'Transparency and third-party testing are key,' Schultz insists. A safe product will come with receipts. Look for clear documentation on what's in the finishes and adhesives, and insist on solid wood over ambiguous 'wood products.' If you see claims like 'eco' or 'non-toxic' but can't find third-party verification, consider it a warning sign. 'Proprietary blend' ingredients? Vague descriptions? Walk away. Price is another indicator. Genuinely food-safe, well-crafted furniture rarely comes at a bargain-basement rate. Brands like Max & Lily are upfront about using GREENGUARD® Gold finishes on their solid pine pieces. And the new wave of heirloom-quality makers (Oeuf, Milton & Goose, and Piccalio) are direct about their use of natural, food-grade materials. Bigger names like Avocado are now featuring GREENGUARD® Gold collections too. The research is catching up: indoor air quality, chemical exposure, and children's health are all inextricably linked. U.S. regulations are beginning to reflect this, albeit slowly, as attention to issues like PFAS and formaldehyde grows. Schultz puts it plainly: 'Over the past decade, parents have become a lot more informed about indoor air quality and everyday exposures. We've seen this with organic food, non-toxic cleaning products, even mattresses. Now that same awareness is shifting to what kids are breathing in and touching day after day in their bedrooms.' Don't get distracted by cute hardware or a clever product name. Before you buy, ask for real answers: Will food-safe become the rule, not the exception? Schultz thinks so. 'Not just as a premium feature but as the baseline standard for kids' furniture. We're at this intersection of wellness and home design where people are rethinking what they bring into their homes, realizing it matters just as much as the food on their plates or the air they breathe.' Style doesn't have to come at the expense of safety anymore. The real measure of quality isn't a trend or a label, but the assurance that what's in your child's room is as safe as it is well made. When a bed rail is finished with food-safe materials, there's nothing left to second-guess.

Debunking #GutTok — What Works & What Doesn't
LA Times Studios may earn commission from purchases made through our links. If you've spent any time on TikTok recently, you've probably stumbled into the world of gut health. The #GutTok hashtag alone has racked up more than six billion views, making gut health comparatively one of the most popular wellness topics online. Fermented foods, fiber bombs, cleanses, and probiotic drinks flood your feed. It's easy to feel overwhelmed or misled. Which trends are real gut-boosters? Which are marketing smoke and mirrors? And what does science actually say? Well, integrative medicine physician (and Activia's gut glow-up guru), Dr. Amy Shaw, shared her knowledge with LA Times Studios to determine what really works. Many products that claim to support gut health don't actually help your body. Dr. Shaw says, 'There's people selling all kinds of tonics and cleanses and all kinds of things that actually have nothing to do with the gut and might hurt you more than it'll help you.' Take yogurt, which is often the poster child of probiotic foods is a good example. 'Everybody's like, 'Oh, yogurt is yogurt.' But that's just not true. There are yogurts out there that actually have no live bacteria,' Dr. Shaw explains. Pasteurization and processing can destroy probiotics, and some brands load them up with sugar, which feeds the less-friendly microbes in your gut. If you want probiotics that make it to your digestive tract, you need specifics. Strain names and to know what they are claiming to treat (i.e., Bifidobacterium longum for reducing inflammation) and a dose between at least 1 billion and 10 billion colony-forming units (CFUs) per serving. If neither is listed, it's likely not doing much for your microbiome. Want to know if a product is truly healthy? Check the label. Just because it says 'gut healthy' doesn't mean it is. Dr. Shaw advises, 'You have to look at the back of the product and see if the bacteria are listed. Look for probiotic species listed. If you don't see it, then it's probably not a probiotic food.' Too much added sugar can shift the microbial balance toward species that thrive on simple carbs and crowd out the beneficial bacteria you are trying to nurture. This imbalance can fuel inflammation and digestive discomfort, so if you're going to have a 'gut healthy' drink with 20 grams of sugar, this will send mixed messages to your microbiome and actually do more harm than good. She adds, 'A lot of drinks or products will have a label on it that says 'gut healthy,' but that doesn't necessarily mean that it has fiber, or probiotics, or anything that's good for your gut.' Fiber fuels your good gut bacteria, and probiotics bring in live microbes that help keep your digestive system balanced. Without these, a product might just give you the placebo effect. Juice cleanses and gut 'resets' have become major trends. The idea of hitting a quick reset button on your digestion is undeniably appealing. But the science suggests otherwise. And while many of us are looking for a quick fix, what really works is food and nutrition. 'There's no FDA-approved test for juice cleanses, and the best way to change your gut is through food,' Dr. Shaw explains. Juice cleanses are typically low in fiber, protein, and fat (because you're just drinking juice), which are nutrients your body needs to keep digestion steady and blood sugar balanced. That said, a few days of drinking only juice will most likely make you feel refreshed and temporarily less bloated, but relying on juice alone for too long can actually shrink the variety of bacteria in your gut, which is the last thing you want. Some popular gut hacks can backfire, as they're not supported by scientific evidence, Dr. Shaw explains. Try focusing on simple, reliable habits that can work better over time, like eating plenty of fiber and drinking enough water. Sounds too easy, but these small changes can really help create a healthy environment for good bacteria to thrive. What does a gut-friendly routine actually look like? Dr. Shaw breaks it down like this: '30 grams of protein in the morning, 30 grams of fiber throughout the day, and three probiotic foods every day.' No complicated supplements or pricey powders required. Just real, everyday food. Protein helps your body bounce back after fasting overnight and keeps your energy up. Fiber is the fuel your good gut bacteria love — it helps them make special compounds that calm inflammation and support your immune system and even your brain. And probiotic foods like yogurt, kefir, sauerkraut, or kimchi introduce live bacteria that keep your gut balanced and healthy. Gut health isn't just about food. How you live matters too. Moving regularly, managing stress, and spending time outside help good gut bacteria thrive. Dr. Shaw says these microbes 'produce special compounds called short-chain fatty acids that travel throughout your body and support health.' Exercise increases the variety of these microbes, boosts your immune system, and improves sleep — all protecting your gut lining and overall health. To manage stress, simple actions like meditation, deep breathing, or walking outside balance your hormones, reduce inflammation, and protect your gut. It's easy to chase the latest gut health trends, but your digestion works best with steady habits. And pay attention to what your gut needs daily. Balance your meals with whole foods that feed your microbiome. Or stay hydrated, and manage stress in ways you can maintain. Your gut will grow stronger and healthier as you practice these habits. If you want to give your gut a boost, there are a few trusted products that fit well with Dr. Shaw's balanced approach. Start with a high-quality probiotic yogurt that contains live cultures to help maintain a healthy digestive balance. Siggi's Probiotic Skyr, Activia's Probiotic Yogurt, and Nancy's Probiotic Whole Milk Yogurt are known to be good options. For adding fiber easily, a ground flaxseed supplement can be mixed into smoothies or oatmeal—it's a simple way to increase your daily fiber intake and feed your good gut bacteria. If you're looking for fermented foods beyond yogurt, Bubbies Sauerkraut is a great option that contains live probiotics and no added preservatives. To support digestion naturally, try a prebiotic fiber powder like NOW Prebiotic Fiber Powder, which helps nourish beneficial microbes in your gut. Finally, for gentle digestive relief and enzyme support, Zenwise Health Digestive Enzymes provide a blend of enzymes that aid in breaking down food and can help reduce occasional bloating. Gut health may be having a moment, but the hype often comes with a side of misinformation. If someone promises an overnight cure or a total 'reset' in just a few days, it's a sales pitch, not science. The microbiome adapts gradually, over weeks or even months, so quick fixes rarely deliver. Watch for red flags: products marketed with dramatic 'before and after' weight-loss photos, supplements without credible research or clear dosages, influencers urging you to 'DM for details' to skirt regulations, or at-home microbiome tests touted as diagnostic tools despite lacking FDA approval. You can protect yourself by sticking to information from qualified professionals, questioning anything extreme, expensive, or overly restrictive, and focusing on proven habits.
