3,000 mg of nine Essential Amino Acids 636 mg of Leucine (Per 4 Capsules) For muscle growth and recovery* 0g sugar, carbs and fat Free of dairy, egg, soy and gluten Essential Amino Acids (EAAs) must come from the diet Protein in the human body is made up of 20 different amino acid building blocks. Your body is naturally able to synthesize some of these amino acids, but there are nine that humans cannot make. These nine amino acids must come from the diet and are called "essential" or "indispensable" amino acids. These essential amino acids are: Leucine, Lysine, Valine, Isoleucine, Phenylalanine, Threonine, Methionine, Histidine and Tryptophan. Fitness Labs Amino Fit  contains all nine essential amino acids, just like a complete protein source. Read more EAAs and "whole" protein pills Other brands promoting EAAs in pill format are often made with whole proteins like whey or soy. That means they have to pack extra non-essential amino acids into their pills, and sometimes even some carbs and fat. The result? More pills, larger pills, or both. For reference, whey protein isolate is about 90% protein. Of this protein in whey, about 40-50% comes from essential amino acids. That means you have to take over 6 grams of whey isolate to get 3 grams of essential amino acids, even though whey isolate is one of the best possible sources of essential amino acids. Read more Individual EAAs Amino Fit , on the other hand, contains just the more expensive, pure, individual amino acids. The result? A fat free, sugar free, carb free product with more essential amino acids per capsule than whole protein pills of the same weight. These individual amino acids also absorb much faster than whole protein, and are free of common allergens like dairy, egg and soy that are typically found in whole protein pills. Dairy free Egg free Soy free Gluten free Read more Optimal EAA ratio Amino Fit uses the same ratio recommended by the most recent Joint WHO/FAO/UNU Expert Consultation Report on " Protein and Amino Acid Requirements in Human Nutrition ." In this report, they outline how much of each essential amino acid people need per day to optimize protein synthesis and live healthy. To do this, they analyzed a number of studies on each individual essential amino acid at a range of intakes, including nitrogen balance studies and stable isotope studies. We have taken this research and created a formula based on the same ratio of essential amino acids they recommend for human requirements. Read more Directions: Take 4 capsules with water daily, with or without food. Take before or after workouts, with low protein meals or another time of day to boost your amino acid intake. Keep a bottle at the office or in the gym bag and take throughout the day.
