Choose Whey Protein when…
You tolerate dairy, want the fastest-digesting option with the most research behind it, and prioritise a complete amino acid profile in a single source.
Choose Plant Protein when…
You're vegan or lactose-intolerant, prefer plant-based nutrition, or find whey hard to digest. Choose a blended plant protein for a complete amino profile.

FAQ
Is whey better than plant protein for muscle?
Whey has a slight edge per gram due to its leucine content and fast absorption, but plant proteins build muscle just as well when you hit your total daily protein target, especially using blends.
Which is easier to digest?
It's individual. Some people find whey causes bloating (especially concentrate); others digest it fine. Many find pea or rice blends gentler. Try both and see what suits you.
When should I choose plant protein over whey?
Choose plant protein if: you are vegan or vegetarian; you are lactose intolerant (though whey isolate has minimal lactose); you have a whey allergy (rare); or you prefer to avoid animal products for environmental or ethical reasons. For performance purposes, a high-quality plant protein blend (pea+rice, or soy) that provides adequate leucine per serving is functionally equivalent to whey for most people's muscle-building goals when daily protein targets are met.
