The Active Ingredient Is: Methylsulfonylmethane (MSM)

MSM is an organic sulphur compound used as a dietary supplement to help support connective tissue health and skin structure. This product uses OptiMSM, a high-purity form of MSM sourced to provide bioactive sulphur.

Form and source details show OptiMSM is produced to a purity of 99.9% via a multi-stage distillation process and is used as the active ingredient in this vegan formulation.

What Does Methylsulfonylmethane (MSM) Do?

MSM supplies bioactive sulphur, which is involved in the formation of collagen, elastin, and keratin and may support joint comfort and mobility as described in the available research context. It also supports skin, hair, and nail health through sulphur-related roles in connective tissues.

MSM is reported to have anti-inflammatory and antioxidant effects that can contribute to tissue health, with ongoing debate around its role in maintaining connective tissue integrity and collagen production.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
