Amino acid that may improve sleep quality by lowering body temperature.
Clinical dose: 3000-5000 mg

Reduces cortisol, improves stress resilience, supports testosterone levels
Clinical dose: 300-600 mg
Safety: Possible side effects include mild digestive discomfort, nausea, or headache, typically dose-related and more common when intake is escalated quickly.
Glycine
Sleep benefits are legitimate at 3g dose before bed. Collagen "glycine" claims are valid since glycine is the primary amino acid in collagen. However, separate glycine supplementation for skin/joint is less proven than complete collagen peptides.
Ashwagandha
Marketing claims: "Boosts testosterone," "Eliminates stress." Reality: Studies show modest testosterone increase (15-17%) primarily in stressed/infertile men, not healthy adults. Stress reduction is well-supported but requires 600mg/day for 8+ weeks. Single low doses show minimal effect.
