Deep-dive guides
Gum disease and 2.12 extra years of epigenetic age
In 1,926 US adults aged 50+, severe periodontitis tracked with 1.35 to 2.12 extra years on several DNA-methylation clocks. The design is a snapshot. This piece separates marker from cause, then grades the adjunct evidence: resveratrol 2.80 vs 3.02 mm in 38 smokers, omega-3 minus 0.43 mm pooled over 15 trials, certainty very low to low.
In plain terms: People with severe gum disease had age-prediction tests reading 1 to 2 years older in one large study. It is not proof that gums cause aging. Supplements tested for gums moved healing by well under half a millimetre on top of dental cleaning. Clean between your teeth daily and treat gum disease properly.
Peptide school: the basics in plain English
What they are. What they do. What to watch out for. A short introduction for people starting from zero.
In plain terms: Think of peptides as tiny chains of building blocks. Some are used in medicines. Others are still experiments. Learn the difference in about 3 minutes.
Daytime light and aging bodies: the 202-person trial that moved
A randomized study of 202 adults aged 63 to 92 ran 12 weeks of home lamps above 8,000 melanopic EDI. Sessions before 10:00 tied to more daytime activity and less fragmented rest. Consensus targets: 250 melanopic lux by day, 10 by evening, 1 at night. Office tests show 37 minutes more sleep. 2 charts, 1 table, 9 verified PubMed sources.
In plain terms: Bright light in the morning helps the body clock. In a trial of 202 older adults, morning lamp use improved activity and sleep patterns. Daytime indoor light should be bright, evening light should be dim. Light is free but it does not extend lifespan.
Does sunscreen cause cancer? The 470,000-person study says no
A UK Biobank analysis of 472,672 adults is viral as proof sunscreen causes skin cancer. It is observational, its own author attributes the link to sun exposure, and the only randomized trial found 50% fewer melanomas with daily use. Covers FDA absorption trials, the benzene recall, and the GRASE split. 2 charts, 1 table, 9 verified sources.
In plain terms: A huge study found sunscreen users get more skin cancer, but that is because sun-sensitive people use the most sunscreen. In the one trial where people were randomly assigned to daily sunscreen, they got half as many melanomas. No study shows sunscreen causes cancer.
6 aging clocks moved in a drug trial. That is not rejuvenation.
A phase 2a analysis in 42 IPF patients moved six proteomic aging clocks over 12 weeks. The paper's own authors say the signal may reflect disease control, not slower aging. Puts CALERIE and 41 intervention studies in context. 2 charts, 1 table, 10 verified PubMed sources.
In plain terms: A drug for lung disease made six age-prediction tests read younger in 42 patients. The researchers say this could be because the drug helped the lungs, not because the patients got biologically younger. Diet and exercise studies show much smaller clock changes over years.
Memory supplements tested: 6 trials, 6,750 adults, 1 cheap winner
Six randomized trials rank memory supplements: a daily multivitamin wins on breadth in 5,203 pooled adults, ginkgo biloba showed nothing in 3,069 adults over 6.1 years, B vitamins work only with elevated homocysteine, creatine helps memory specifically. 2 charts, 1 table, 6 verified PubMed sources.
In plain terms: A cheap daily multivitamin showed small but real memory benefits in large trials. Ginkgo biloba did nothing in a six-year study of 3,069 people. B vitamins help if your homocysteine is high.
Peptide gray market in numbers: 5 warning letters, AU$120,000 seized, 2.5x dose gaps
August 2026 enforcement data: 5 FDA warning letters in one day, an AU$120,000 TGA seizure, Melanotan II dosing spreads of 2.5x, against 8,069-participant GLP-1 meta-analysis evidence. 2 charts, 2 tables, 9 verified sources.
In plain terms: Regulators caught peptide sellers shipping unapproved products with wrong doses. The medicines they imitate have trials with thousands of people. The copies have none.
Omega-3 EPA/DHA ratio: the endpoint decides the ratio, not the bottle
REDUCE-IT cut MACE 25% on 4 g/day pure EPA. STRENGTH cut nothing on 4 g/day mixed. Which EPA:DHA ratio for which endpoint, at which dose, across 58 referenced trials. 7 charts, 6 decision cards.
In plain terms: Fish oil labels are confusing. This guide says which type of omega-3 to take for your specific goal, heart, triglycerides, or general health, and at what dose.
NMN vs NR in 2026: the first head-to-head trial says both work, neither wins
Rebuilt on 25 human trials: the 2026 head-to-head RCT, the reversed FDA position on NMN, the EU 300 mg/day cap on NR and the price data that inverts the old narrative. 8 charts, 6 decision cards.
In plain terms: NMN and NR are both NAD boosters sold as anti-aging pills. The first direct comparison trial found both raise NAD about equally, so price per dose should decide.
Magnesium forms: glycinate for sleep, threonate for cognition, oxide for price
Independent guide to 8 magnesium forms with elemental math explained, 28 PubMed references, 9 charts and a decision framework per goal.
In plain terms: Not all magnesium pills are the same. Different forms help with different things: sleep, memory, or just price. This guide matches the form to your goal.
Creatine dose by goal: 5 g for muscle, 20 g for brain
Creatine dose depends on the goal. 5 g/day builds muscle. Brain uptake needs 20 g/day for 4 weeks. Sleep deprivation: single 20 g bolus. Evidence-based dosing per goal.
In plain terms: Creatine is not one-size-fits-all. 5 g a day builds muscle. The brain needs about 20 g a day for weeks before anything changes. One big dose can help after a sleepless night.
Latest analysis
Protein restriction: what 350 studies say about eating less protein to age slower
A review of 350+ studies from Cell Press Blue found that eating less protein activates the same longevity pathways as calorie restriction, without cutting calories. The findings challenge the high-protein trend in longevity circles. Here is what the evidence actually says, what it does not say, and what it means for the supplements on this site.
In plain terms: Scientists reviewed about 350 studies on eating less protein. Moderate protein looks best for long life in humans. Very low protein can backfire.
NMN's cognitive breakthrough: what the largest trial actually found
The biggest NMN RCT to date shifted from physical endpoints to cognitive function. We separated what the data shows from what the marketing will say.
In plain terms: The largest NMN memory trial to date tested older adults. Some thinking scores improved. Here is what the study found, and what it did not.
GlyNAC reversed 9 hallmarks of aging in humans: what it actually means
A Baylor trial showed that two cheap amino acids reversed 9 of 12 aging hallmarks. We explain what was measured, what was not, and why the price matters.
In plain terms: Older adults took glycine plus NAC for 24 weeks. Many age markers in their blood moved in the younger direction. One small study, but the changes were broad.
Multivitamins may slow biological aging: what the 2-year trial actually shows
A Mass General Brigham analysis found daily multivitamins slowed DNA methylation age over 2 years. We explain epigenetic clocks, their limits, and what this means for the cheapest supplement in your cabinet.
In plain terms: A 2-year trial followed people taking a daily multivitamin. Their biological age markers aged slightly slower than the placebo group.
Glucosamine linked to faster cognitive decline: what the study found
A major study found glucosamine, one of the most popular joint supplements, was linked to faster progression from mild cognitive impairment. We explain observational evidence, confounding, and what to do.
In plain terms: A large health survey found people taking glucosamine scored worse on memory tests over time. It is a weak form of evidence: a link, not proof.
1 in 3 multivitamins fail testing: what ConsumerLab found in March 2026
ConsumerLab tested multivitamins and 32% failed. We break down what failing means, which products had problems, and how to check your brand.
In plain terms: ConsumerLab bought multivitamins and tested them. About 1 in 3 failed: wrong doses, missing ingredients, or contamination.
The PCAC vote that could legalize six underground peptides
On July 23 and 24, 2026, an FDA advisory panel voted to recommend BPC-157, MOTS-c, KPV, TB-500, Epitalon, and Semax for legal compounding, over the objections of FDA's own reviewers. Here is what actually happened and why the vote is not the finish line.
In plain terms: A US FDA advisory committee voted to let compounding pharmacies make six peptides now sold on the gray market. Here is what that vote changes, and what it does not.
The only price comparison that matters: per effective dose
$149 vs $203 vs $99 tells you almost nothing. Price per gram of active substance, and price per studied-dose day, is the real comparison, and it changes the answer.
In plain terms: A cheap bottle can be the expensive one. The number that matters is cost per day at the dose actually tested in studies, not the sticker price.
Why most longevity supplement reviews can't be trusted (and what we did instead)
Most YouTube reviews, blogs, and "scam or legit" pages in this category are affiliate-driven. Here's the honest breakdown of what we accepted, what we downweighted, and what we openly rejected.
In plain terms: Most supplement review sites earn commission when you click buy. That shapes their rankings. We list the warning signs of paid recommendations.
NOVOS Core's RCT: sponsor-funded, unreplicated, and still Tier 1
NOVOS is the only brand in this comparison with a peer-reviewed randomised trial on its exact finished product. It's also the only one where the company paid for the study. Both facts belong on the page.
In plain terms: NOVOS funded its own trial. The result looked good, but the company paid for it and nobody has repeated it. We explain why we still count it, and with what caveats.
DoNotAge's NMN and the German lab that confirmed the label
An independent German lab tested DoNotAge's NMN and found roughly 99% purity, slightly above what the label claimed. In a category where most "tested by independent lab" claims come with no document, that's rare. Here's what it does and doesn't prove.
In plain terms: An independent German lab tested DoNotAge's NMN and confirmed the label: 99%+ purity. Rare good news in a market full of false labels.
IM8's "kitchen sink" formula, in plain language
Independent Spanish and UK press asked physiologists what David Beckham's supplement actually does. We rewrote the case in our own words, kept the receipts, and flagged what nobody has verified yet.
In plain terms: IM8 puts 90+ ingredients in one drink. Independent reviewers found most doses too small to matter. You pay for a long label, not proven effects.
