Question

Whey vs Plant Protein: Which Is Better?

ProteinPrice Editorial · Accepted Answer

Whey protein has higher leucine content per gram (about 11% leucine vs 6-8% in most plant proteins) and a higher digestibility score (DIAAS 1.09 for whey vs 0.65-0.85 for most single-source plant proteins). This means whey triggers muscle protein synthesis more efficiently per gram. Plant proteins close the gap when used as a blend (pea + rice + hemp), at higher per-serving doses (35-40g instead of 25g), and they have the advantage of being dairy-free, lower in IGF-1 elevation, and often less expensive per gram of protein.
