How are we different?

Our Iso-C® Whey Protein Powder consists of whey protein isolate produced via a gentle filtration process from European cow's milk. It provides a complete amino acid profile with all essential and branched-chain amino acids (EAAs & BCAAs).

Our unsweetened Natural Whey Protein Isolate contains a single ingredient and comes with a natural, milky flavour. We place particular emphasis on ensuring all our protein powders are produced without silicon dioxide, artificial flavours, artificial sweeteners, or added sugar. This purity and omission of unnecessary additives sets our premium products apart from standard market alternatives.

We use particularly high-quality, airtight flavour protection bags with zippers for packaging. These offer a high level of protection against moisture and external influences.

Proteins

Whey protein is derived from whey and is further categorised into whey protein concentrate, isolate, hydrolysate and clear whey protein isolate (clear whey) according to the respective production method. All whey proteins are characterised by a very high protein content and high biological value due to their complete amino acid profile, including all essential (EAA) and branched-chain amino acids (BCAA). The biological value indicates how well a dietary protein can be converted into the body's own protein.

Whey protein concentrate naturally has a higher fat and lactose (carbohydrate) content than whey protein isolate.

According to the European Food Safety Authority (EFSA):

Proteins contribute to

  • An increase in muscle mass
  • The maintenance of muscle mass
  • The maintenance of normal bones
