(Approved by the European Food Safety Authority (EFSA)).

Main highlights

The whey proteins from milk are the so-called complete proteins, because they provide the body with all the necessary complete proteins, including the 9 amino acids which the body cannot synthesise and that must be absorbed by food (i.e. histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine)
The 100% whey isolate has even more added ingredients: an ‘amino acid matrix’ which provides extra amino acids, as well as L-leucine, L-glutamine and taurine. L-Glutamine is the most common free amino acid in the human body.
Nutritional proteins are a source of nitrogen and essential amino acids that the body needs for the maintenance and growth of the body tissue. That's why the 100% whey isolate contributes to the maintenance and growth of muscle masses and also to maintain normal bones. (These statements have been approved by the European Food Safety Authority.)
Mix one serving (25 g) daily with 300 ml of water, milk or other liquids. Preferably take it after training
100% whey isolate is an excellent quality protein made exclusively from whey. In general, these whey ‘isolate’ proteins are produced to have a higher proportion of protein than whey ‘concentrate’, which also means the isolate contains less sugar (enclosed lactose) and fat!
