Nutrition & Supplements
Supplements, peptides, diets and foods checked against the research: what the human trials found, the doses they used and the risks they saw. Plain-English verdicts with every source linked.
-
Eight trials pitted saffron for depression against an SSRI and found no gap in mood scores, with fewer side effects. Why that is still not proof of a tie.
-
Does lion’s mane mushroom really help memory? Only about 185 people have been tested in placebo-controlled trials, and the results disagree. See the evidence.
-
Spermidine benefits look strong in food studies and weak in capsules: a year-long trial in 100 older adults found no memory gain from the wheat germ pills.
-
A continuous glucose monitor has no proven health benefit if you do not have diabetes. Here is what it can honestly measure, and what it cannot tell you.
-
About six servings of fermented foods a day raised gut microbe diversity and cut 19 inflammatory markers in a small Stanford study. A bigger trial did not repeat it.
-
Possibly, but the proof is thin. GlyNAC raised muscle glutathione 164% in a 24-person trial, while a 114-person test at a lower dose found no rise.
-
The J-curve says moderate drinking protects the heart. Correct one basic bias and it collapses. What the evidence really shows about alcohol health risks.
-
Kiwifruit benefits, ranked by evidence: two green kiwifruit a day rival psyllium for constipation, with promising extras for sleep, immunity, mood, and iron.
-
Ultra-processed foods drove 508 extra calories a day in the one controlled trial. See what the science really shows about weight gain and disease risk.
-
No solid human evidence shows the epitalon peptide lengthens telomeres or extends lifespan: zero registered trials, only cell data, and a real cancer question.
