Rule1 Essential Amino 9

When it comes to supporting muscle building and maintenance, these nine "essential" amino acids are aptly titled. Since they can't be synthesized within our bodies, they must be obtained through nutritional sources. Essential Amino 9 delivers 7.5g of essential amino acids in every serving, plus added electrolytes for hydration.^†

Mix one (1) scoop of Essential Amino 9 with 8-12 oz. of cold water or your favorite beverage. 

On non-training days, enjoy it any time for additional recovery and hydration support.^

Essential Amino 9 is best taken on training days around your workout. Because it contains no stimulants or added sugars, it may be used day or night without adverse affects on sleep quality. 

Forty years of manufacturing expertise is what separates Rule 1 from the endless sea of companies that sell sports nutrition supplements. Manufacturing technology has always been a key pillar of our vision to be the best nutritional supplement brand in the world.
