You’ll want: A high-quality whey concentrate should provide at least 20g to 25g of protein per 30g serving, with minimal carbohydrate and fat padding, according to Tung. Protein isolates should offer 25g to 28g per 30g serving.
The first or second ingredient on the label should contain words such as “whey protein”, “protein isolate”, “protein concentrate” or “micellar casein”, said Reutens. Put the product down if “sugar”, “maltodextrin” or other fillers are listed upfront.
Avoid: Creamers, oils and blends of amino acids such as glycine and taurine to spike up the supplement’s protein levels, cautioned Reutens. “They should not be listed near whey protein isolate in the ingredient list.”
