CR finds varying quality in popular fish oil supplements

Consumer Reports tested 20 popular fish oil supplements and found no major safety issues like heavy-metal contamination, but some products showed rancidity or contained less omega-3 than claimed. Several manufacturers challenged the testing or noted their products meet standards, while the piece also questions whether most people need fish oil supplements at all, suggesting dietary omega-3s from fish are preferable and stressing proper storage if supplements are used.

Dermatologists Say Collagen Supplements Are Modest Helpers, Not a Skin Miracle

Five dermatologists say collagen supplements aren’t a miracle cure for skin: while some evidence hints at skin-health benefits and joint support, oral collagen may not directly deposit collagen in the skin, and results are generally modest at best. Benefits depend on consistent use and individual biology, and supplements should complement—not replace—a solid skincare routine, SPF, and a healthy diet. Choose well‑formulated brands and be mindful of additions like biotin and animal-sourced ingredients, especially if you have vegan or thyroid considerations.

NMN, NAD+, and Resveratrol: What the science actually says about slowing ageing

Current evidence suggests NMN/NR can raise NAD+ markers in blood and may aid metabolic health in some small studies, but there's no convincing proof they slow ageing or preserve muscle or cognition in older adults; resveratrol has shown effects in lab studies but poor bioavailability and mixed human results limit its anti-ageing claims. The biology is plausible, but real long-term benefits are unproven, and the best proven ways to support healthy ageing are regular exercise, good sleep, a balanced diet, and managing chronic conditions.

Creatine: Brain Fuel and Muscle Power Beyond the Gym

Creatine is a naturally produced molecule stored mainly in muscle that rapidly regenerates ATP to power high‑energy tissues like muscle and brain; beyond athletic performance, it may support memory, processing speed, and mood, with potential anti‑inflammatory/antioxidant benefits in clinical contexts—though effects vary by baseline levels, dosing, and individual physiology. It is not a steroid, is generally safe for healthy individuals, and stores saturate, with excess excreted as creatinine.

Barrière bets on vitamin patches to disrupt the supplement aisle

Barrière is expanding its line of transdermal vitamin patches into Walmart (1,700 stores) and other major retailers, aiming to reach $10 million in revenue in 2026. The patches target sleep, energy, immune support, digestion, and more, with products like a lactose-intolerance patch and a motion-sickness patch; they’re manufactured in the U.K. and deliver ingredients through the skin for up to 12 hours. The company touts convenience and marketing as key drivers in a $60 billion, highly crowded supplement market with limited FDA oversight.

Creatine's true payoff hinges on baseline stores, dosing, and biology

Creatine has potential benefits for muscle and brain health, but its effects vary by baseline stores (lower in women, older adults, and vegetarians may see bigger gains), dose/absorption (3–5 g daily maintenance; carbs can boost uptake; no extra benefit from very high doses due to saturation), and individual physiology. It's not a magic bullet and should accompany proper training and nutrition.

Experts warn against common supplement pairings that can block absorption

A TODAY health explainer warns that popular supplements can interfere with each other at high doses, reducing absorption or causing unintended effects. Notable combinations to avoid include calcium with iron, calcium with magnesium, calcium with zinc, zinc with copper, zinc with iron, and vitamin C with vitamin B12 or high-dose vitamin E with vitamin K. Experts advise taking interacting nutrients several hours apart, consulting a doctor, verifying supplement quality, using third-party certifications, and prioritizing a food-first approach rather than megadosing to replace a healthy diet.

Gary Brecka's day-by-day biohack playbook: sun, breath, hydrogen water and cold plunges

Biohacker Gary Brecka, 55, says he reversed his biological age to 20 using a routine built around morning first-light exposure, breathwork, mineral-enhanced hydration (Baja Gold salt, amino acids, hydrogen tablets), and a four-minute cold plunge or cold shower. He also does light movement, aims for 30 grams of protein in the first hour, and may add red light therapy or hyperbaric oxygen. Nightly, he stops eating hours before bed, dims lights 90 minutes before sleep, magnesium, and a controlled breathing routine to cue deep sleep, striving for about eight hours of sleep in an organic, toxin-free mattress. He emphasizes non-negotiables: sunlight, breathwork, minerals, hydrogen, amino acids, and cold as core levers for daily performance and recovery.

Glycinate Emerges as the Go-To Magnesium for Sleep and Recovery

Experts say magnesium glycinate is best for both workout recovery and sleep due to high absorption and calming glycine, with magnesium citrate as a solid alternative for rapid replenishment after intense exercise. Topical magnesium can help with targeted relief, but oral forms provide more reliable systemic benefits. Most people get enough magnesium from diet; supplementation may help if you sweat heavily, but avoid excessive intake and beware drug interactions; supplements should complement, not replace, a solid sleep routine.

Does the supplement stack actually boost longevity, or is it placebo?

Experts say there’s limited clinical evidence that supplement stacks extend lifespan; any perceived benefits are likely due to placebo or unproven effects, so focus on evidence-based healthy-aging practices instead.

The Supplement Surge: Do We Really Need More Pills?

A Vogue health feature examines the surge in dietary supplements in the U.S.—driven by social media and gaps in care—showing a market of around 100,000 products with limited FDA oversight and thousands of related ER visits each year. While some individuals benefit from treating real deficiencies, experts warn supplements often don’t replace healthy habits and most claims lack robust evidence. The article highlights vitamin D, omega-3s, and magnesium as the best-supported options, though dosing is individual, and emphasizes consulting healthcare providers and relying on proper testing rather than chasing trends.

Unlock Your Daily Magnesium: 13 Foods to Boost Your Health

Vogue lists 13 magnesium-rich foods (kiwi, cucumber, squash, dark chocolate, avocados, nuts, legumes, almonds, leafy greens, seeds, whole grains, bananas, and salmon) and explains magnesium’s role in 300+ bodily processes, noting that many adults fall short of roughly 310–420 mg per day. It covers signs of deficiency (fatigue, cramping, headaches, nausea), tracking intake, and cautions about supplements (laxative effects and variable quality), recommending medical guidance or choosing third-party–tested products if supplementation is needed.

Vitamin D Overload: High-Dose Supplements Pose Toxicity Risks

Vitamin D is essential, but excess intake from high-dose supplements can cause toxicity (hypercalcemia), with symptoms ranging from nausea and fatigue to kidney stones and, in rare cases, kidney failure or fatal bleeding if untreated. Toxicity is uncommon but rising due to popularity and mis-prescribing. Most people recover after stopping the supplement and receiving treatment. General guidance suggests 15–20 mcg (600–800 IU) daily for most people, with an upper limit of 4,000 IU (100 mcg) per day unless advised by a clinician. Emphasis is on obtaining vitamin D from sun exposure and fortified foods first, and consulting a healthcare professional when starting or stopping supplementation.
