If you spend any time in the gym, you’ve probably heard that you need to “eat more protein” to build muscle. But how much is actually necessary? And is more always better?
The reality is that protein intake is often either overcomplicated or misunderstood. Some people dramatically overdo it, while others don’t eat enough to properly support their training. Getting it right can make a noticeable difference to both muscle growth and recovery.
Why Protein Matters for Muscle Growth
Protein plays a key role in repairing and rebuilding muscle tissue after training. When you lift weights or perform intense exercise, you create small amounts of muscle damage. Protein provides the amino acids needed to repair that damage and help muscles grow back stronger.
Without enough protein, this process is limited. Even with a well-structured training plan, progress can stall if your nutrition isn’t supporting it.
How Much Protein Do You Need Per Day?
For most people looking to build or maintain muscle, a good general guideline is:
- Around 1.6 to 2.2 grams of protein per kilogram of body weight per day
So for someone weighing 75kg, that would be roughly: 120g to 165g of protein per day.
You don’t need to hit an exact number every single day, but consistently falling within this range tends to work well for most people who train regularly.
Going significantly above this level usually doesn’t provide additional muscle-building benefits, but going below it can slow progress over time.
How Should You Spread Protein Throughout the Day?
Total daily intake is the most important factor, but how you distribute that protein can also play a role.
Rather than consuming most of your protein in one or two large meals, it’s generally better to spread it across the day.
This gives your body a more consistent supply of amino acids and can help support muscle protein synthesis more effectively.
A simple approach is: 3 to 5 protein-containing meals per day, each meal providing a meaningful amount of protein.
How Much Protein Should You Take Per Serving?
While your daily total is what matters most, the amount you consume per meal or shake can influence how effectively your body uses it.
As a rough guide, many people aim for around 20 to 40 grams of protein per serving.
While general recommendations can provide a starting point, the optimal amount of protein can vary depending on your body weight, training intensity and goals.
This guide from The Supplement Store on how much protein to take per serving breaks it down in more detail and helps you find the right intake for your needs.
Whole Foods vs Protein Supplements
You don’t need supplements to build muscle, but they can make hitting your daily protein target much easier.
Whole food sources like chicken, eggs, fish, lean beef and dairy products should form the foundation of your diet.
However, protein powders such as whey protein can be a convenient option when you’re short on time, need a quick post-workout source, or are struggling to hit your daily intake.
Common Protein Mistakes
1. Not eating enough protein overall
2. Over-relying on shakes
3. Thinking more is always better
4. Poor distribution throughout the day
Final Thoughts
Protein is one of the most important parts of any muscle-building plan, but it doesn’t need to be complicated.
Focus on hitting a consistent daily intake, spreading it across your meals, and using supplements when they’re convenient.
Get those basics right, and you’ll be in a strong position to support your training and make steady progress over time.
