MUSCLE GROWTH
Thanks to its high amino acid content, various studies have demonstrated collagen’s effectiveness in maintaining lean muscle. A new study published in the journal Nutrients demonstrated just 15g of hydrolysed collagen daily, when added to a resistance exercise training programme, led to greater improvements in muscle growth, strength and fat-free mass than training alone. The researchers propose this may be because muscle differs from other tissues in that the cells are enclosed in a connective tissue framework formed mainly of collagen. Resistance training upregulates collagen protein synthesis in the muscle, enabling muscle growth and improvements in strength.
