Muscle Health: MSM may help support muscles during workouts and help fight oxidative stress due to exercise. MSM has been shown to significantly reduced exercise induced muscle damage .

Immune Health: MSM may play a role in supporting the immune response especially in the respiratory tract, well as protecting against immune depletion that comes from strenuous exercise.

Glutathione: MSM bolsters glutathione levels which are directly related to immune health.

Joints: MSM has the ability to support healthy joint function. MSM may help improving joint flexibility.

Skin Health: MSM helps to produce flexible and healthy skin.

MSM is not a drug but an organic form of sulfur and a potent antioxidant made up of: 34% oxygen, 6% hydrogen, 34% sulfur, 26% carbon.
