Healthspan's advanced OptiMSM is made using a patented distillation process to produce one of the purest natural MSM supplements available. Each tablet provides 1,000mg of purified OptiMSM.

Recent research suggests that a higher daily intake of 2-3g of MSM (Methyl Sulphonyl Methane) per day may be needed for optimum results. This is why we are delighted to introduce our high strength OptiMSM® 1,000mg product, making it easier than ever for you to achieve the recommended intake.

MSM is a naturally occurring organic sulphur compound that acts as a major building block of glycosaminoglycans, key structural components of joint cartilage. MSM occurs in small amounts in certain foods however nutritionists believe that diets are generally low in sulphur and therefore often recommend an MSM supplement.
