Rule One – R1 Casein

Slow-Release Micellar Casein Formula

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.
