Something to hold you over until your next meal. A protein that breaks down more slowly, delivering its amino acids over several hours. R1 Casein is what you’re after.

Strawberries and Creme is delicious

I rarely use casein and I'm not a fan of strawberry protein in general but this is solid. I decided to try something new since the Apple Cinnamon in Whey wasn't available. I mixed it in Greek Yogurt and fell for it! I'm hooked. If the Cookies and Creme whey is as solid as this, Rule 1 may be the only protein I buy from here on out.

Salted Caramel is DELICIOUS

Buying protein before tasting can be a hit or miss. This salted caramel is amazing! Not only do I like the taste of this one, I like the thick, creaminess of the mixed consistency. The small size was out of stock (should have been my first hint that it was good), so I was a bit nervous when I had to order the large. I never imagined a protein would taste so good!

Best Casein - but only the salted caramel

I've tried almost all types of Casein out there.. drink one each night and it used to be a unpleasant task until I came across the R1 Salted Caramel.. its just amazing in texture mixability and taste.. I now look forward to it.. so I then tried the chocolate but it was just like all the other mediocre Caseins out there or worse.. left it after 3 attempts and couldnt finish it.. Im back on and will be staying on R1s Caramel for a long time

Best protein I've ever had.

I got the lightly salted caramel, and it's the best casein (or whey) I've ever had. Been getting it for months now, and am buying it in the largest barrels they sell at this point. It's just so good, and very clean.
