A 2013 randomized, double-blind, placebo-controlled study at the University of Tampa examined the effects of Growing Naturals’ rice protein isolate vs. a commercial whey protein isolate supplement in a group of resistance-trained athletes. The athletes completed a robust & supervised exercise regime 3-4 times a week for 8 weeks and consumed the protein supplements within an hour post workout. The subjects also consumed a controlled healthy diet consisting of 25% protein, 50% carbs and 25% fat. After 8 weeks, results indicated that athletes in both protein groups had significant gains in lean body mass with decreases in body fat as well as significant gains in whole body strength and power. Whey protein did not confer additional or superior benefits compared to rice protein.
