Common questions
FAQ
Why do athletes need NSF Certified for Sport protein?
NSF Certified for Sport tests for 280+ substances banned by WADA, NFL, MLB, NBA, and NCAA. A contaminated supplement can end a career. Regular third-party testing only checks label accuracy, not banned substances.
Is whey or plant-based protein better for athletes?
Whey isolate has a more complete amino acid profile and higher leucine content, making it slightly superior for muscle protein synthesis. Plant-based blends (pea + rice) can match whey if properly formulated. Both work for recovery.
How much protein do athletes need?
Research recommends 1.6-2.2g per kg body weight daily for athletes. For a 180lb (82kg) athlete, that's 131-180g per day from food and supplements combined.
