Methylsulfonylmethane - organic sulphur compound supporting joints and inflammation
We rank MSM by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
MSM, or methylsulfonylmethane, is an organic sulphur compound. Sulphur is a mineral that the body needs to build and repair tissues.
It is primarily used to support joint health and manage inflammation, which is the body's natural response to injury or irritation that can cause swelling and pain.
The supplement is produced through a commercial distillation process. This involves heating a raw source to separate the methylsulfonylmethane from other substances, which is then purified into a concentrated powder for use in capsules or tablets.
This ingredient is generally mid-range in price. This is because the distillation and purification processes required to ensure the sulphur is stable and safe for consumption add more cost than simpler, raw mineral supplements.
