Product Information

R1 BCAAs

When it comes to muscle maintenance, BCAAs are literally essential. This group of aminos cannot be synthesized within our body; they must be obtained from high protein foods and supplements. R1 BCAAs delivers all three critical amino acids in a 2:1:1 ratio of leucine to isoleucine and valine. Our BCAA formula is micronized to easily mix into water or your beverage of choice.*

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.

RULE 1 PROTEINS: Manufactured in America, No Banned Substances, Gluten free

Awesome flavor and mixes well. A little early to tell if it is working. Rule 1 products are the best and can't beat the price with great deals from M&S.*
