Frequently Asked Questions

How much protein do I actually need per day?

For active adults, 1.6–2.2 g per kg bodyweight (Morton et al., meta-analysis 2018). A 180 lb lifter targeting muscle gain: ~130–180 g/day, ideally spread across 3–5 meals.

Is plant protein as good as whey?

Per gram, no — whey has more leucine, the key trigger for muscle protein synthesis. But 40g of pea+rice blend closes most of the gap if you add 5g leucine.

Can I just eat chicken?

Yes. Whey is a convenience tool, not a requirement. The cheapest gram of protein in your kitchen is usually whole eggs, canned tuna, or a rotisserie chicken.
