I see a lot of people taking the Branched amino acids compared to the free form of amino acids? Currently I'm taking the free form, made by Ultimate Nutrition. I like this brand over some others because it contains 8 of the essential AA and 10 of the non essential. Most one's I see at the store only have 4 types of Amino Acids.
Can somebody clue me into why BCAA seem more popular? Posibly explain the positives versus the Negatives?
Give me good details too, I'm a biomedical science graduate with big background in biochem and physiology. It's just that we never covered amino acid supplements...
