Older men with muscle loss who do strength training and take collagen supplements gain more muscle mass (4.2 kg) than those taking a placebo (2.9 kg).

Similar Assertions

Older men with muscle loss who take collagen supplements during strength training lose more body fat (5.4 kg) than those taking a placebo (3.5 kg).

98%

When older men with muscle loss take collagen supplements during strength training, gaining muscle is more closely linked to losing fat compared to those taking a placebo.

95%

Strength training boosts bone mass in older men with muscle loss, but adding collagen supplements doesn't make it better than just training alone.

84%

Middle-aged men doing strength training and taking this collagen supplement build 1.6 kg more muscle than those taking a placebo.

77%

Middle-aged men doing strength training and taking this collagen supplement lose 1.9 kg more body fat than those taking a placebo.
