Our Review Process

Every supplement reviewed on this site is evaluated against the published scientific literature. We evaluate:

• Active ingredient doses vs. clinically studied amounts
• Third-party testing certifications (NSF Certified for Sport, Informed Sport, USP)
• Price-per-serving relative to competitors and raw ingredient sources
• Label transparency — no proprietary blends hiding underdosed ingredients
• Heavy metal testing and contaminant screening results where available
• PubMed citation accuracy — we check the studies brands cite
• Manufacturing quality: GMP-certified facilities
• First-person use experience: taste, mixability, side effects, and actual results

Editorial Independence

Brands cannot pay for higher rankings or more favorable reviews. We include both strengths and weaknesses for every product. All recommendations come from our editorial team based on real hands-on testing, not affiliate potential.
