You should count branch chain amino acids (BCAAs) toward your daily protein target because technically, they are protein.
BCAAs are amino acids, just like the amino acids that you get from whey protein or a chicken breast. The reason that companies are able to list BCAA products as having zero calories and protein is because the FDA won’t allow a company to list free form amino acids as having calories.
To count them, you’ll just need to note the total number of grams of amino acids advertised on the label. For example, a serving of Xtend contains seven grams of amino acids, meaning that you are seven grams of protein closer to hitting your daily protein target.
