When thinking about which collagen to choose, we often focus on the dose. However, the main factor influencing the effectiveness of a collagen course is its molecular weight. The collagen in Collagène Mama has a molecular weight of 2,000 Daltons, which allows for optimal absorption. According to a clinical study, taking a collagen food supplement containing 2.5g per day is sufficient to achieve visible results in as little as 4 weeks, particularly for skin hydration and the reduction of fine lines. For lasting effects, a 3-month course is recommended, though the dosage may vary depending on each person's individual needs, lifestyle and other factors such as sun exposure or alcohol consumption.
