For middle-aged men doing strength training, whey protein and this collagen supplement have similar effects on muscle gain and fat loss.
Scientific Claim
In middle-aged untrained men, 12 weeks of resistance training combined with 15 g/day of whey protein does not significantly differ from BODYBALANCE® collagen peptides in improving fat-free mass or fat mass.
Original Statement
“The exploratory analysis showed no statistically significant differences between WP-G and CP-G or P-G, regarding changes of fat free mass and fat mass.”
