The special combination of pure whey isolate and whey hydrolysate makes R1 Protein one of the most popular products from Rule 1. The result is an optimized product with 87% protein purity and 25g of protein (per serving) that acts noticeably faster. Additional benefits come from ingredients such as the more than 6g of BCAAs and the low calorie content (110 kcal). Furthermore, there is virtually no sugar or fat used. The instantization ensures easy mixing. You will search in vain for fillers or artificial preservatives that dilute the proteins. This results in a particularly effective protein supplement that can aid in muscle building.
