Collagen supplements are marketed for various benefits, including improved skin elasticity, joint health, and muscle mass. However, individuals sometimes report an increase in body weight after beginning collagen supplementation. Several factors may contribute to this perceived or actual weight gain.
The potential for weight increase should be understood in the context of overall dietary habits and lifestyle. Collagen supplements, depending on the formulation, can contain calories. Some products include added sugars or flavorings, which contribute to caloric intake. Moreover, increased muscle mass, a potential benefit of collagen in conjunction with resistance training, can lead to a higher scale weight despite a decrease in body fat percentage. Water retention, potentially influenced by changes in dietary protein or sodium intake often associated with supplement routines, can also temporarily influence body weight.
