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.

-
No. Adrenal fatigue is not a real diagnosis: a review of 58 studies found no support, and its cortisol tests disagreed. What the tiredness usually is.
-
The best melatonin dosage is smaller than the bottle suggests: benefit flattens near 4 mg, and taking it 2 to 3 hours before bed matters more than milligrams.
-
Exogenous ketones promise endurance and focus without the diet. Pooled trials show no speed gain, common gut symptoms, and a retail price near $1 per gram.
