- AAB6 days agoRated 5 out of 5 starsThe smoothest protein ever! & Toddler approved
Just got the bag last month and it is almost gone. We give our kids each a half scoop daily. It is perfect for smoothies or just on its own mix with water. It is genuinely the smoothest protein I’ve ever had sometimes vanilla can have that alcohol taste to it and this tastes just like the description - vanilla bean. I’m so impressed! The chocolate is just as good (if not BETTER if you’re a chocolate lover). So glad that REP decided to go the nutrition route and handed over these awesome, clean products!

I don’t know how they successfully this protein bath tasty AND Incredibly smooth (and still clean), but they did! Ian beyond impressed. The milk chocolate tastes straight up like a Hershey kiss, and the vanilla is the best vanilla protein I’ve ever tasted, hands down. I love these products and I’m so grateful for a company that values CLEAN ingredients.

The chocolate flavor is subtle. Product ingredients are great and mixes well in shaker bottle. Look forward to using in variety of ways with other recipes.

Whey protein isolate is a highly refined form of whey protein that contains at least 90% protein by weight. The term "isolate" refers to the additional processing that removes most of the fat, lactose, and carbs, making it a purer and more digestible protein source. This makes it ideal for athletes, lifters, and anyone looking for a lean protein with minimal extras. Compared with whey concentrate, isolate has higher protein content (90%+ vs. 70-80%), lower lactose, and less fat and carbs, making it easier to digest and a great choice for muscle recovery. It also absorbs faster, making it especially effective for post-workout nutrition. If you want a clean, high-protein option without excess fillers, whey isolate is one of the best choices.
