About
Reports on health and wellness claims bordering beauty, and on the manufacturers, retailers, and regulators whose filings and enforcement actions shape what reaches shelves. Every claim carries its evidence grade and the conditions under which it was actually studied.
Comes to the desk through close reading of clinical study design, dosage, and study population, distinguishing a controlled trial from a marketing-funded pilot. Before a health claim runs, the original study is checked for who funded it, how large the sample was, and whether the result generalizes beyond the tested group. Recall notices, warning letters, and trade body statements are read in full, not through summaries, before industry coverage is published.

The "Light a Candle When You Get Home" Trend: What the Science Actually Shows

-
Tim Spector Says Exercise Doesn't Cause Weight Loss. The Study Behind That Claim Is Still Being Argued Over
Tim Spector's viral claim that "exercise doesn't help you lose weight" rests on one contested 2016 Hadza hunter-gatherer study, not on "all the studies," and newer trials and official UK guidance push back.

New Menopause Guidelines Give Hormone Therapy Its Strongest Endorsement Yet. The Fine Print Still Matters.

Can Health Trackers Help You Manage Menopause Symptoms?

The Glucosamine-Alzheimer's Study Everyone Is Sharing Measured Something Narrower Than the Headlines Say

The "Best Magnesium for Sleep" Claim Rests on Weaker Evidence Than the Bottles Suggest

The "Natural Ozempic" Headline Spain Keeps Writing, Minus the One Number That Matters
Spanish outlets keep asking if berberine is a "natural Ozempic," and the newest entry, from El Mundo's Yo Dona, still skips the number that would settle it: a 2025 meta-analysis puts berberine's weight-loss effect at under a kilogram, against semaglutide's 12-15% body weight loss in trials.
