Adding this collagen supplement to strength training doesn't help middle-aged men reduce waist size more than a placebo or whey protein.
Scientific Claim
In middle-aged untrained men, 12 weeks of resistance training combined with BODYBALANCE® collagen peptides does not significantly reduce waist circumference more than placebo or whey protein.
Original Statement
“The decrease in waist circumference was more pronounced in the CP-G (−3.41 ± 2.22 cm) compared with the P-G (−2.50 ± 4.19 cm), but the group differences were not statistically significant (p = 0.292; d = 0.270).”
