Independent supplement reviews graded against the published research, including when the evidence says don't buy.
Each review grades the product's ingredients one by one against published trials, names what the marketing overclaims, and says plainly who should skip it. Our rating is an evidence grade, not a sales score — no product can buy a verdict here.
Arctic Blast is a menthol and camphor rub. The DMSO the sales pages lead with is listed on the label as an inactive ingredient, and the trials behind each ingredient are thin. It may ease minor aches for a while. Diclofenac gel has far better evidence.
FemiCore is a daily capsule of cranberry, bearberry, berberine, Mimosa pudica and five probiotics, all in two undisclosed blends. We found no trial showing any of them reduces bladder leaks. Pelvic floor training has much better evidence and costs little.
Flexi Move is sold for joint support, but its label is a 500 mg blend of tribulus, fenugreek, saw palmetto and other herbs normally found in testosterone products, with no doses shown. We do not recommend it for joint pain.
GutSave is a daily capsule of fish collagen, cinnamon, sea moss, papaya seed, black cumin, colostrum and probiotics. The label shows every dose, and each is a fraction of what the trials used. Fibre has much better evidence for constipation.
Java Burn is now coffee drops with green tea, green coffee, L-carnitine and L-theanine in an undisclosed 550 mg blend. Those ingredients have shown about 1 to 2 kg of extra weight loss in trials, at doses the blend is unlikely to reach.
Joint Genesis is a one-a-day capsule of Mobilee hyaluronic acid, pine bark, boswellia, ginger and black pepper, with every dose on the label. The ingredients have small, mostly positive trials. The product itself has none, and exercise and diclofenac gel have better evidence for less money.
A genuine 500 mg magnesium dose spread across seven forms. The trouble is that the sleep evidence for magnesium is thin, the split between forms is hidden, and one of the seven is magnesium oxide.
A melatonin sleep formula with every dose on the label. The 3 mg of melatonin has modest evidence; the 5-HTP rules out anyone on antidepressants, and the amino acids sit below their trial doses.
Keeps is a US telehealth service that sells generic finasteride and minoxidil after an online consult. Those are the two hair-loss drugs with strong trial evidence, and its prices are reasonable. The drugs are the point; the service adds convenience. Read the finasteride side-effect evidence first, and note it does not serve the UK.
Measured is a US telehealth clinic that prescribes Wegovy, the Wegovy pill and Zepbound after an online assessment, and sells cheaper compounded versions. The branded drugs have strong trials. The real monthly cost is membership plus medicine, it serves 26 states, and there are no refunds.
An oral probiotic whose honest case rests on three of its five strains. The finished product is untested, the per-strain doses are hidden, and it won't regrow gums. A low-risk try for mild symptoms, and a waste of money for anyone expecting a cure.
An ingredient-by-ingredient look at ProstaVive against the published research, which parts of the formula have real trial evidence for urinary symptoms, which don't, and who should skip it entirely.
Protoflow is sold for prostate support and prints every dose. Most of the formula is libido herbs, and its saw palmetto is about a quarter of the dose that failed to beat placebo in trials.
ProvaDent is a chewable tablet with xylitol, cranberry and four unnamed probiotic strains. Oral probiotics have some support for gum bleeding, but the sales page shows no label, doses or strain names, so its claims cannot be checked.
A melatonin-free sleep drink with every dose on the label. L-theanine and glycine are dosed like the trials; the rest are small doses or ingredients with no sleep evidence.
Two of its eight ingredients have real glucose trials behind them. The other six target energy and weight. The best-evidenced blood-sugar ingredient is missing entirely, and there is an interaction risk with diabetes medication that most reviews never mention.
Berberine has the best trial record of any glucose supplement. This capsule uses 250 mg of dihydroberberine, a form with absorption data and no glucose trials, and berberine interacts with many common drugs.
The ingredient list is unusually sensible for this category. The doses are the problem: melatonin sits below the studied range and everything else hides inside a 637 mg blend. Reasonable for mild trouble falling asleep, wrong for anyone on antidepressants.
