MSM is seen by many practitioners as the perfect partner to glucosamine. Most companies currently supply petrochemical MSM but our MSM is naturally sourced. Each tablet provides a full 1000mg of MSM, making it one of the most potent products on the market. It is also one of the best value MSM products available to practitioners and customers. 1 to 2 tablets daily with a meal. Caution: Do not take if pregnant or breast feeding.
