MSM is an organosulfur compound that provides a bioavailable source of sulfur. This is critical for synthesizing the master antioxidant glutathione and for maintaining the integrity of connective tissues like cartilage. Its primary healthspan relevance lies in its potential to reduce chronic inflammation and oxidative stress, key drivers of aging, particularly in the context of joint and skin health.
