The Active Ingredient Is: Methylsulfonylmethane (MSM)

MSM is an organic sulphur-containing compound used as a supplement to support connective tissue health and overall tissue resilience.

This form, commonly marketed as TruFlex MSM, is designed for effective absorption and to deliver biologically active sulphur to tissues such as cartilage, tendons and skin.

What Does Methylsulfonylmethane (MSM) Do?

MSM contributes to the maintenance of connective tissue integrity and participates in antioxidant defence, supporting normal tissue function and resilience. It may support skin hydration and elasticity, and can assist with immune cell vitality during physical stress according to available scientific context.

These roles align with EFSA and NHS understandings of how micronutrients and related compounds support normal physiological processes such as collagen formation, keratin production and antioxidant protection.
