Why does the collagen powder contain vitamin C and other additives? Are they not superfluous? — Collagen for Joints with Cherry Flavor 300g - Iconfit

Hydrolysed collagen in this powder is a protein already broken down into peptides, which dissolves and is absorbed more easily than intact collagen. But collagen does not work in isolation in the body: for its own synthesis the body needs vitamin C. That is why the combination of ready-made peptides and vitamin C makes sense: one component supplies amino acid fragments, while the other takes part in their further use.

The other substances in the formula complete the picture:

• Glucosamine sulfate and chondroitin sulfate are structural elements of cartilage tissue, which are often included in joint formulas.
• MSM is an organic sulfur compound important for connective structures.
• Hyaluronic acid is part of tissues in the body and helps retain moisture, not only in cosmetics.
• Boswellia extract is a plant component traditionally used in formulas to support freedom of movement.
• Calcium, magnesium, zinc and manganese are minerals involved in processes related to bone tissue.

This formula means it covers several areas at once: collagen peptides, support for their synthesis, cartilage components and a mineral base. This is convenient if you want to include one complex in your diet instead of several separate supplements. However, check the composition if you already take other joint products, so as not to get an excess of the same substances.
