Frequently Asked Questions
How much protein do I need to build muscle?▾
Research suggests 1.6–2.2 g of protein per kg of body weight for muscle gain. This calculator uses 1.6 g/kg as a baseline and more for very active lifters.
Can you eat too much protein?▾
Very high intakes (over 2.5 g/kg) offer little extra benefit for healthy people, but they are not usually harmful unless you have kidney disease. Spread intake across meals for best absorption.
