Evidence-based ingredients

What the research actually says.

Creatine Monohydrate

Over 500 peer-reviewed studies support creatine monohydrate for strength output, power during high-intensity exercise, lean mass development, and training adaptation. The 5g daily dose is the consensus recommendation across all major sports nutrition guidelines. Endorsed by the International Society of Sports Nutrition as the most effective ergogenic supplement currently available.

Vitamin D3

Vitamin D3 (cholecalciferol) supports calcium absorption, bone density, skeletal muscle contractile function, and immune defense. Deficiency is documented in 35–70% of athletic populations, particularly among indoor athletes and those in northern latitudes. D3 is approximately 87% more effective than D2 at raising serum vitamin D levels.

Complete Multivitamin

A quality multivitamin closes the micronutrient gaps consistent training creates — B vitamins, zinc, Vitamin K, and the full coverage profile — without requiring individual supplementation of each. Daily micronutrient coverage and routine simplification, not a cure-all. Tested via HPLC, ICP-MS, and microbiological analysis.
