Biohacker Ranks 100 Supplements From Best to Worst Based on Science

Supplement selection remains one of the most confusing aspects of health optimization, with thousands of products making bold claims but limited guidance on what actually works. Siim Land tackled this challenge by systematically evaluating 100 popular supplements using evidence-based criteria including research quality, safety, bioavailability, and proven effectiveness.

Land's analysis revealed a clear hierarchy, with foundational nutrients dominating the top tiers. Vitamin D, magnesium, and omega-3 fatty acids earned high rankings due to widespread deficiencies and robust clinical evidence. Creatine and protein powder also scored well for their proven performance and recovery benefits. Mid-tier supplements included compounds with promising but limited research, while bottom-tier products were characterized by poor bioavailability or marketing hype exceeding scientific support.

The ranking methodology prioritized supplements addressing common nutritional gaps over exotic compounds with minimal human studies. Land emphasized that supplement quality varies dramatically between brands, making sourcing and third-party testing crucial factors. He also highlighted the importance of individual biochemistry, noting that optimal supplement protocols should be personalized based on diet, lifestyle, and health status.

For longevity-focused individuals, this analysis provides valuable guidance for building evidence-based supplement protocols. The findings suggest that focusing on a few high-quality, well-researched supplements typically delivers better results than complex stacks of unproven compounds. However, viewers should remember that supplements complement, rather than replace, fundamental health practices like proper nutrition, exercise, and sleep optimization.
