Two protein sources.

Both supply the protein your muscles use to repair and grow; the differences are practical: whey is a complete dairy protein that is rapidly absorbed and very high in leucine, while plant blends are dairy-free and need good pairing (such as pea plus rice) to cover all amino acids.

What to do

Pick one based on your diet and digestion: plant protein if you are vegan or sensitive to dairy, whey if you tolerate it and want the most leucine per scoop. What matters most is hitting your total daily protein; the source is secondary.
