What matters most

  • Pea protein is plant-derived; whey is milk-derived.
  • Both can provide substantial protein, but the exact amino-acid profile and serving amount vary by product.
  • Dietary preference, dairy tolerance, taste and cost often drive the decision.

How to use this information

Protein-powder decisions are easier when you separate the basic nutrition question from the marketing. Start with your overall eating pattern, then decide whether a supplement solves a real convenience or dietary-fit problem. Once a powder is useful, compare the label rather than relying on front-of-pack superlatives.

  • Choose pea if plant-based or dairy-free status is important.
  • Choose based on the actual label, not category reputation alone.
  • Evaluate protein per serving and how the product fits your overall intake.
