Optimal Protein Intake for Muscle Growth
How Much Protein Do You Need?
Research suggests that optimal protein intake for muscle growth is approximately 1.6–2.2 grams per kilogram of body weight per day (Phillips & Van Loon, 2011). For example, a 70 kg (154 lbs) individual should aim for 112–154 grams of protein daily.
Consuming an adequate amount of protein supports muscle repair, growth, and overall recovery. However, excessive protein intake beyond this range provides minimal additional benefits and may lead to digestive discomfort or unnecessary caloric intake.

Quality Matters
Not all protein sources are created equal. High-quality proteins provide essential amino acids crucial for muscle synthesis. Animal-based proteins like chicken, fish, eggs, and dairy products have a complete amino acid profile, whereas plant-based sources like lentils, quinoa, and tofu require strategic pairing to ensure adequate nutrient intake (Jäger et al., 2017).
Timing and Distribution
Studies indicate that evenly distributing protein intake throughout the day maximizes muscle protein synthesis. Instead of consuming the bulk of your protein in one meal, aim for 20–40g per meal to optimize muscle repair and growth (Areta et al., 2013).
Pre- and post-workout nutrition also plays a vital role. Consuming protein-rich foods within 30–60 minutes after exercise aids recovery by replenishing amino acids necessary for muscle repair.
Common Myths About Protein Intake
There are many misconceptions about protein consumption, such as the idea that high-protein diets harm kidney function. Research shows that for healthy individuals, high protein intake does not cause kidney damage (Poortmans & Dellalieux, 2000). Another myth is that plant-based diets lack sufficient protein for muscle growth, yet many elite athletes successfully build muscle with plant-based nutrition.
