Whey protein isolate is usually the top pick for muscle growth because it’s fast-absorbing and packed with essential amino acids. Casein is a good option before bed since it digests slowly and keeps feeding your muscles overnight. Plant-based proteins like pea or rice work too, but they often need blending to get a complete amino acid profile. The best choice depends on your diet, budget, and how your stomach handles it—so don’t just grab the first tub with a flashy label.
