What exactly is Whey Protein?

Whey protein (milk protein) is a natural component of milk produced during cheese making: the liquid whey is filtered and gently dried until a powder with a high protein content remains. Whey provides all nine essential amino acids and is particularly rich in leucine. Because it is quickly digested and easy to prepare as a shake, it is the most widely used protein source in sports. Whey is available in three forms: as a concentrate (the classic with full flavor), as a more highly filtered isolate with a higher protein content, and as a hydrolysate, in which the protein has already been broken down into smaller components. Which variant is suitable depends on your goals, tolerability, and budget.

What to look for when buying?

First, pay attention to the protein content per 100g – good products clearly state it in the nutrition table. Then decide between concentrate (full flavor, cheaper) and isolate (more protein, less fat, carbohydrates, and lactose). It's worth looking at the ingredient list: short lists without unnecessary fillers speak for the product. Also, compare the price per serving instead of per tub – package sizes vary greatly. And when it comes to taste: classics like vanilla and chocolate are the safe choice; it's best to try unusual flavors in a small size first.

Frequently Asked Questions

I'm lactose intolerant – what should I look out for?

Whey isolates typically contain significantly less lactose than concentrates due to the manufacturing process. Take a look at the nutritional information and the label – for severe intolerance, isolates or vegan proteins are the more common choice.
