Alanylglutamine
L-Alanyl-L-Glutamine is a dipeptide form of glutamine that is more stable and water-soluble than free glutamine. Despite better intestinal absorption and muscle delivery than glutamine alone, it does NOT improve athletic performance according to current evidence. C-grade for fatigue symptoms (small effect). D-grade for heart rate, ACTH, and CD4 cells (no effects). Marketed for hydration and endurance but evidence doesn't support these claims for healthy athletes.

Colostrum

Colostrum, also known as first milk, is a mammary secretion produced by cows and related animals. The results of supplementation are similar to supplementing whey protein, though colostrum may offer some unique benefits for the immune and digestive systems.
Beta-Alanine
2 shared conditions · 82 outcomes
Beta-alanine is a non-essential amino acid that increases muscle carnosine, buffering acid during high-intensity exercise. B-GRADE evidence for anaerobic capacity (18 RCTs, 331 participants, small improvement). Works best for exercise lasting 1-10 minutes. The 'tingles' (paresthesia) are harmless but annoying. One of the most evidence-backed sports supplements alongside creatine and caffeine. Does NOT improve aerobic exercise (D-grade).
Vitamin E
1 shared condition · 274 outcomes
Vitamin E is a fat-soluble antioxidant that protects cells from oxidative damage and is found in several common foods. Supplementing with extra vitamin E does not have broad health benefits, except in people with vitamin E deficiency, and long-term high-dose supplementation may cause harm.
Vitamin C
