Whey Protein

What is whey protein from milk?

Whey protein is one of the most popular protein supplements in sports nutrition. It is obtained from whey, the liquid part that separates during the processing of milk and cheese. Whey protein contains all the essential amino acids and is known for its fast absorption, which is why it is widely chosen by people who train and practise strength sports.

When should you take whey protein?

Thanks to its fast absorption, whey protein is often chosen post-workout, but it can also be added at breakfast or as a protein snack during the day. The amount and timing may vary depending on your goals, diet and physical activity.
