Honey may ease a child's night cough a little: the review's placebo figure was about twice what its largest trial found, and a 2022 double-blind trial found no difference. Never give honey to a baby under one.
We said nobody had tested a creatine gummy. Three groups had. Of 27 products, 13 held almost no creatine and 9 met their labels, while every powder tested held its label. None of the tests is peer reviewed, and every tester sells something.
In pooled trials it helps people keep going a little longer in hard efforts of about one to ten minutes: a median gain of 2.85% in a 2012 review. Pooled, 20 trials found no change in body composition.
Glycinate is sold on absorption. The trial built to test it found 23.5% versus 22.6% for cheap magnesium oxide, in twelve patients missing part of the bowel, and two company studies in healthy adults did not put it ahead either.
A scoping review found 19 records and three small tests of tallow creams on people, none against a moisturiser. A second study read 200 posts: nine cited any evidence.
The best result came from 20 people with mild sleep apnea, any blocked nose treated first. The trials since are small and point both ways, and we found no test at all of the jawline promise.
In adults with type 2 diabetes, 10-minute walks after each meal shrank the rise in blood sugar after meals by 12%, and after dinner by 22%. The week's average did not move.
In the Cochrane review the bandage cut swelling 30 to 38.6% and the massage added 7.11%, in 83 women; six of seven trials since found it added nothing measurable. In people without lymphedema the studies are small, and few test what it is sold for.
Twenty-eight trials say psyllium lowers LDL cholesterol. For weight, the maker's own pooling found 4.6 pounds and independent ones found about 2 or none. Semaglutide moved 28.
Swallowed, castor oil has a confirmed receptor mechanism and trials and hospital records in more than two thousand women. As a pack, the small tests found no sign it gets through skin, no change in liver tests and no difference from a dummy pack.
