Key takeaways The strongest independent human evidence for collagen peptides is not skin — it is tendon collagen synthesis, where a publicly funded University of California, Davis trial found gelatin plus vitamin C timed before exercise raised collagen-synthesis markers (Shaw et al. 2016). Skin hydration, elasticity, and wrinkle claims are the most heavily marketed use, … Read more
Key takeaways Strongest evidence: creatine monohydrate at 3-5 g/day increases upper-body strength by roughly 4.4 kg and lower-body strength by roughly 11.4 kg beyond resistance training alone in adults under 50, and produces similar gains in older adults doing resistance training (Burke et al. 2024, Sharifian et al. 2025). Cognitive benefits are real but narrow … Read more
Key takeaways Strongest evidence: correcting low dietary intake, migraine prevention (300–600 mg daily under medical supervision), and modest blood-pressure reduction — with meta-analyses supporting a systolic drop of ~2 mmHg (Cochrane, Journal of Human Hypertension). For sleep, anxiety, muscle cramps, depression, diabetes, and bone health, evidence is mixed to weak — a systematic review found … Read more
