It can make you feel healthier and more robust, making weight loss easier as muscle burns more calories than fat throughout the day.

Consuming a protein-rich diet and drinking lots of water when taking collagen is best to avoid these adverse reactions. Collagen peptides are broken down by digestion into combinations of amino acids, which work as needed in physiological processes.
