Weight gainers are typically higher in
protein than
whey protein supplements. However, the
protein content comprises a significantly larger percentage of whey protein supplements than weight gainers. A lower-calorie weight gainer may contain 35 grams of protein, while a higher-calorie weight gainer may supply 100 grams of protein. However, given calorie amounts of 620 and 1,860, the protein comprises just 22.5 and 21.5 percent of the calories in these gainers.
