Since the way of using protein is very personal, our products provide lists of pros and cons for you to make the best choice! If you have any doubts about a product, read our blogs.
What is the best protein?
If you practice weight training, you probably already know that protein contributes to muscle recovery and muscle increase. There are many varieties on the market, but whey protein is best known. Whey is a by-product of cheese, which after processing becomes either Whey concentrate, whey isolate or whey hydrolysate. In the same order as its lactose quantity. Bear this in mind if you are lactose intolerant. If you want to know which form of protein suits you best, read below.
What is whey concentrate?
During the process of making cheese, cow milk is pasteurized to get rid of harmful bacteria. After this, enzymes are added to separate the milk into whey and curd. The curd gets made into cheese. The remaining whey thereafter is dried with hot air and turns into a fine powder, which gets filtered via crossflow microfiltration. This results in a whey concentrate with a protein percentage of approximately 78%. Products of this variety are among others, Whey Delicious and Perfect Whey Protein.
What is whey isolate?
Whey isolate goes through an extra round of crossflow microfiltration, which results in an even purer whey because more carbohydrates and fat are filtered out. This whey isolate has a protein percentage leading up to 93%!
What is whey hydrolysate?
Very pure whey isolate gets hydrolysed to create whey hydrolysate. A process that influences the absorption of the whey. Basically, the protein particles get cut in smaller di- and tripeptides, the smallest possible form of protein. This makes Whey Hydrolysate the ultimate protein for working out. Additionally, whey hydrolysate contains little to no lactose, and is usually tolerable for those sensitive to lactose.
