Egg yolk – rich in nutrients and important for hormones
The egg yolk not only provides protein, but also healthy fats, vitamins (especially vitamin D) and cholesterol, which is important for hormone production, especially testosterone. Testosterone plays a central role in muscle building. However, egg yolks should be consumed in moderation so as not to overdo the fat and cholesterol intake.
Conclusion for muscle building:
A combination of egg white and egg yolk is optimal to benefit from both advantages – the high protein content of the egg white and the nutrients of the yolk.

How many eggs per week are safe?
For healthy adults , up to 7 eggs per week are considered safe, even if they contain a high proportion of yolk. Studies show that moderate consumption of eggs has no significant effect on cholesterol levels, provided a healthy diet is maintained. Athletes with higher calorie and protein needs may also be able to consume more eggs, but should reduce the proportion of yolk while watching their fat intake.
Meeting protein needs – a challenge?
Despite their nutrient density, eggs alone may not be enough to meet the high protein needs of athletes. Especially for fitness enthusiasts who want to build muscle mass, it can be difficult to get the necessary amount of protein from diet alone. This is where high-quality protein powders come into play, such as those found in the Protein range from Athletic Supplements .
These products offer a simple, quick and calorie-conscious way to supplement your protein needs - ideal after training or as a snack. With a variety of flavors and nutritional values, they are the perfect addition to a balanced diet.
Conclusion
Eggs are an excellent source of protein, and both the white and the yolk have their benefits. For muscle building, a combination of both is ideal, although the amount of yolk should be controlled according to individual calorie needs. However, if you are struggling to meet your protein needs through eggs or other foods alone, protein powders are a convenient and effective solution to help you achieve your goals.
