How much protein do athletes actually need? – Protein requirements scientifically reviewed

Protein is the fundamental building block of life. Whether it's muscles, tendons, hormones, or enzymes – almost everything in our body is made of proteins. For athletes, the question of the right amount is essential, because training always means wear and tear, followed by repair. But how much protein do you really need to make progress?

The Basics: Why the Need Increases

Every intense training session causes microscopic tears in the muscles and strains connective tissue. To not only repair these structures but also make them stronger for the next challenge (supercompensation), the body needs amino acids. While a non-athlete gets by with about 0.8 g per kg of body weight, active people need significantly more material for these adaptation processes.

The Magic Limit: What Does Science Say?

For a long time, the saying in strength training was: "The more, the better." However, current studies (e.g., Morton et al., 2018) paint a clearer picture. For most strength and endurance athletes, the optimum is around 1.6 g of protein per kg of body weight per day. Anything significantly above this value generally brings no additional benefit for muscle growth, but is merely used by the body as an energy source or excreted by the kidneys.

Quality Over Quantity: Biological Value

It's not just the number on paper that counts, but how well your body can utilize the protein. This is where biological value comes into play. The more similar the dietary protein is to the body's own proteins, the more efficiently it can be used. Particularly high-quality options include:

• Whey (whey protein): The highest biological value and extremely fast absorption – ideal after training.
• Combinations: For example, potatoes with eggs or grains with legumes (greatly increases the value of vegan sources).
• Organic quality: Pure proteins without artificial sweeteners and flavors also relieve the metabolism.

How Do I Meet My Needs in Everyday Life?

In a stressful everyday life, it can be a challenge to consistently reach your targets. A healthy breakfast with low-fat quark and oats often provides the first 40–50 g. For quick supply immediately after exercise or as a snack, high-quality organic protein powders are a blessing. They are easily digestible and provide exactly the building blocks your body needs after exertion.

Conclusion: Control Instead of Guesswork

You don't have to eat huge amounts of meat to achieve athletic success. With the 1.6-gram rule, you're on a scientifically sound and healthy path. Pay attention to the origin of your proteins and give your body the purity it deserves to perform at its best.
