Whey Protein Isolate

Whey protein isolate packs 90%+ protein by weight and achieves the fastest absorption rate among all protein sources, spiking blood amino acids within 60 minutes. Meta-analyses confirm it optimizes muscle protein synthesis post-exercise better than any other supplement, including lentils or beef. At $1.50 per 25g serving, it is 30% cheaper per gram of protein than grass-fed beef, making it a cost-efficient choice for athletes.
