Whey vs Plant Protein: What to Look For

Nutrition4 min read

Standing in front of a wall of protein tubs is genuinely confusing. Whey, pea, soy, blends - here’s what actually separates them and how to choose.

Whey protein

Whey comes from milk and is the most popular choice for a reason: it mixes smoothly, tends to taste good and is naturally rich in the amino acids many people look for around training. It suits anyone who isn’t avoiding dairy.

If dairy or lactose is something you watch, many people prefer a whey isolate to a standard concentrate - check the label and pick what suits your diet.

Plant protein

Plant powders - pea, soy, rice or blends - are the go-to if you’re vegan, dairy-free or simply prefer them. Blends are common because combining sources gives a fuller amino-acid profile than a single plant on its own.

Texture is a little earthier than whey, but modern plant powders have come a long way on taste.

What to check before you buy

Whichever camp you’re in, the same short checklist applies:

  • Protein per serving - roughly 20g is a typical, useful amount
  • A short, recognisable ingredients list
  • A flavour you’ll genuinely enjoy (you’ll drink it more often)
  • Dairy-free clearly stated if that matters to you
