Why does a foot gel contain glucosamine and chondroitin if it is applied externally?

Glucosamine and chondroitin — substances associated with the structure of cartilage tissue — are indeed more often found in oral supplements. In topical products they are added as part of a comprehensive formula aimed at the area of the joints and muscles.

It is important to understand the difference: the gel is a cosmetic product for external use, and the way it works is fundamentally different from taking supplements by mouth. The manufacturer does not claim that the glucosamine and chondroitin in the gel restore cartilage or penetrate into the joint — such claims belong to the field of medicine, not cosmetics.

In a topical gel, these ingredients work above all as part of a formula that makes application more pleasant and targeted — especially when combined with massage. Massaging the gel in boosts local circulation, and the warming effect of Methyl Nicotinate adds to this sensation.

If you are interested in systemic joint support, that is a separate question worth discussing with a specialist. The gel is not a substitute for medical treatment or oral supplements and is not intended to diagnose or treat any condition.
