Premium Supplements Dietary Supplement Dr. Mercola has been providing quality products since 2001. In every extraordinary capsule of MSM, you’ll find: OptiMSM (Methylsulfonylmethane) – I only wanted the best MSM ingredient in my sulfur formula and believe I definitely found it with OptiMSM. Due to the manufacturer’s 4-stage rigorous distillation process, consistency and purity became non-issues. N-Acetyl Cysteine (NAC) - Since this sulfur amino acid is considered the starting point for the production of glutathione in your body, it was important to include it in my formula. NAC works as an antioxidant and can also promote your body's healthy detoxification processes. R-Alpha Lipoic Acid (from Sodium R-Alpha Lipoate) – Due to its capability to increase glutathione levels and to be readily absorbed when taken orally, I made sure alpha lipoic acid (ALA) was included in this formula. Plus, I didn’t just go half-way… instead I took it to another level. Not only is R-alpha lipoic acid (R-ALA) the preferred form of lipoic acid, the R-ALA that I chose is superior in stabilization and can provide up to 21 times more bioavailability. Organic Sulfur Vegetable Blend - Naturally-occurring organo-sulfur compounds can be found in certain vegetables. One such group of nutrients called isothiocyanates are derived from sulfur-containing compounds found in cruciferous vegetables like broccoli, kale, and green cabbage. Allicin, another organo-sulfur compound, is the beneficial phytochemical found in garlic. Commitment to consistency and high quality – As with the other supplements I offer on my site, MSM is no exception when it comes to my commitment to providing high quality. To complement a diet rich in sulfur along with safe sunlight exposure, I recommend you consider MSM to help your body get the adequate amounts of sulfur it needs. And with this formula, you have the potential of enhancing the production of super-antioxidant glutathione within your body.
