Casein is a protein that even doctors recommend consuming at night, as it stays in your body for hours, providing you with the amino acids you need during your night's rest.*

Pretty standard casing, avathol casings make sure you add a little bit extra water or enjoy a thicker shake*

Great after-dinner snack. I blend 50g of Rule1 Casein with 30g of granola, 15g of cacao nibs, and 20g of peanut butter powder with water to the desired thickness. Delicious.*

R1R1R1 Casein is the smoothest mixture when added to any liquid, even water. The flavors are great, especially the Cookies and Cream!*

Excellent choice for the price. Most brands are unreasonably expensive. I buy my casein when M&S has a sale and the price is right. Rule 1 casein does not mix quite as easily as some of the more expensive brands, but who cares!*

This is my "go-to" as an evening snack. I mix 40 grams of casein with 35 grams of granola and 15 grams of cacao nibs, then blend them all together.
Cures all of my after-dinner cravings!*
