Collagen has become one of the most talked-about supplements for improving skin elasticity and supporting joint health but did you know it can also play a role in weight management? Studies show that collagen peptides can help preserve lean muscle mass, support satiety, and even reduce cellulite appearance when combined with healthy habits.
Let’s explore which types of collagen powders, peptides, and liquids actually deliver results.
Key fact: Regular collagen intake can reduce body fat by up to 4 % and improve muscle definition when combined with resistance training (Clinical Nutrition, 2019).
