Middle-aged men doing strength training and taking this collagen supplement build 1.6 kg more muscle than those taking a placebo.
Scientific Claim
In middle-aged untrained men, 12 weeks of resistance training combined with 15 g/day of BODYBALANCE® collagen peptides results in a 1.59 kg greater increase in fat-free mass compared to placebo.
Original Statement
“The main analysis revealed a statistically significantly higher increase in fat free mass (p = 0.010) in the CP-G compared with the P-G. ΔCP-G = 3.42 ± 2.54 kg; ΔP-G = 1.83 ± 2.09 kg”
