3. Promote weight loss: Weight loss requires burning fat (catabolism), and the hydrolysis of collagen can increase and prolong this catabolism process, burning more fat to achieve the purpose of weight loss. Moreover, collagen's repair effect on cells consumes a lot of heat energy, and this effect consumes a lot of heat energy.
