How Much Protein Per Day to Build Muscle?

The short answer: 1.6 to 2.2 grams of protein per kilogram of bodyweight per day. Here's where that number comes from, how to split it, and how to hit it without obsessing.

The science-backed number

Multiple meta-analyses agree that protein intake to maximise muscle growth tops out around 1.6 g/kg, with little extra benefit beyond 2.2 g/kg. Going higher won't hurt — it's just unnecessary.

GoalProtein targetExample (70 kg)
Build muscle (surplus)1.6–2.0 g/kg112–140 g
Fat loss (keep muscle)2.0–2.4 g/kg140–168 g
General health1.2–1.6 g/kg84–112 g
Note: protein is slightly higher when cutting — it protects muscle while you're in a calorie deficit.

How to split protein across the day

Aim for 3–4 meals of 25–40 g each. Spreading intake stimulates muscle protein synthesis more often than a single large dose, and it's easier on digestion.

Easy ways to hit your target

Protein is only half the equation

Protein builds the muscle, but total calories decide whether you gain or lose. Pair your protein target with the right calorie goal — learn how in our TDEE & BMR guide, or just let the generator do it.
