The Active Ingredient Is: MSM (Methylsulfonylmethane) (OptiMSM Form)

MSM is a naturally occurring sulphur compound used as a source of sulphur for normal connective tissue formation. OptiMSM denotes a vegan-ready form of MSM commonly used in supplements.

This form is supplied as OptiMSM, a vegan-grade ingredient noted for its bioavailability and suitability for plant-based diets.

What Does MSM Do?

MSM is involved in supporting connective tissue formation, including cartilage, and contributes to collagen and keratin synthesis, which can influence skin and nail health. These roles align with established understandings of nutrient function for body structures and tissues.

EFSA and NHS-aligned guidance recognise normal functions of nutrients in connective tissues and structural support, with sulfur-containing compounds playing a part in these processes.
