Supplementing with 15g of collagen peptides daily, taken within 60 minutes after resistance training, significantly increases fat-free mass, muscle strength, and fat loss in elderly men with sarcopenia compared to placebo.
If you are an older man experiencing muscle loss, take 15 grams of collagen peptides every day. On days you lift weights, drink it within an hour of finishing your workout. Stick with this for at least 3 months alongside a consistent resistance training program to see significant improvements in muscle mass and strength.
Our data demonstrate that compared with placebo, collagen peptide supplementation in combination with resistance training further improved body composition by increasing FFM, muscle strength and the loss in FM.
Why this rating
Randomized, double-blind, placebo-controlled trial with a specific population (elderly sarcopenic men), though sample size is moderate (n=53).

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
