Micronutrients & recovery
Supplementing with 30g daily hydrolyzed collagen peptides during intense resistance training does not increase myofibrillar or muscle connective tissue protein synthesis rates compared to placebo.
If you are doing intense resistance training, taking 30g of collagen daily will not make your muscles or connective tissue build protein any faster than if you took a placebo. While collagen does increase specific amino acids in your blood, it does not translate to higher synthesis rates for muscle or connective tissue in this context. Focus on your training and overall protein intake rather than relying on collagen for synthesis stimulation.
Collagen peptide supplementation (2 x 15 g daily) does not increase myofibrillar or muscle connective protein synthesis rates during 1 wk of intense resistance exercise training in young, recreational athletes.
Why this rating
Randomized, double-blind, placebo-controlled trial with objective biomarkers (deuterium oxide tracing) and muscle biopsies.
