What is OptiMSM®?

MSM, methylsulfonylmethane (METH- l-sul-FON-il-METH-ane) also known as dimethyl sulfone (DMSO2) and methyl sulfone, is a source of organic sulfur important for optimal health.

Sulfur is a nutrient that acts as a critical component of key molecules that make up connective tissue throughout the body, including joint and skin tissue. Sulfur is also a major building block of one of our body’s most critical antioxidant defense systems, which helps defend us against oxidative stress and free radicals1.

Health Benefits

OptiMSM® contains 34% elemental sulfur, and has been shown to support several health benefits like muscle and exercise recovery, joint mobility, and healthy skin and hair*. Without sufficient MSM sulfur, a body cannot maintain an appropriate level of homeostasis.

MSM is a sulfur-containing compound and can be found naturally in high-concentration in plants and animal sources. However, for vegans and vegetarians, relying on plant sources may prove to be difficult since the sulfur content of soil influences sulfur concentrations in plants which can vary greatly.

As a source of sulfur, OptiMSM® delivers critical nutrition to your cartilage to maintain healthy joints and connective tissue1. OptiMSM® supplementation has been shown to deliver multiple health benefits – from supporting skin health by decreasing the appearance of fine lines and wrinkles2 to maintaining the body’s antioxidant capacity to help aid in exercise recovery3,4. OptiMSM® helps you live well, age well, and perform well.
