Product Information

R1 Casein

Even in our fast-paced world, there are times when it pays to slow down. Take between meals and bedtime for example. During these occasions you want a protein that takes its time. 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.*

RULE ONE PROTEINS™ COMMITMENT TO QUALITY

Since day one, Rule 1 Proteins™ has proven that exceptional quality and superior value aren’t mutually exclusive. We develop our own products, source the finest ingredients, and manufacture them in a FDA-inspected, NSF/GMP-compliant, and Informed-Choice certified facility. Streamlining and tightly controlling every phase of the process, from start to finish, enables us to offer premium products without the premium price.

this is a great Casein protein. for me, I hate proteins that don't mix or half of the protein is stuck on the buttom of the shaker. I had no problem with Rule 1 R 1 Casein. and the light salted Carmel is the perfect flavor to mix with a Chocolate whey. I usually, mix one scoop of Casein and whey together. mostly b/c of the mix-ability. its pretty good in water or Milk. Best of doesn't destroy the inside of the shake before bed or anytime that I'm not going to get a meal in for a long time.*
