Most other MSM supplements do not contain OptiMSM® which has been clinically proven to be the purest MSM world-wide. OptiMSM® is the only MSM that undergoes a 4-step distillation process to prevent impurities and contaminants. Most MSM compounds only undergo crystallization which traps contaminants as it cools. Most MSM products are not made in the USA. Most other supplements don't include BioPerine® proven to increase bioavailability. The truth is that most MSM supplements do not live up to their claims. Most do not have the potency needed. And most contain ingredients such as unnecessary proprietary blends, additives, preservatives, fillers or binders.

In terms of quality and purity of ingredients, there is nothing else on the market that comes close to Approved Science® MSM.
Methylsulfonylmethane (MSM) is a natural source of sulfur found in our bodies and in nature. Sulfur is an essential nutrient for our bodies because it builds and fixes DNA and protects cells from oxidative damage which can lead to serious diseases. Sulfur also promotes skin health as well as proper functioning of the tendons and ligaments.
Third-party testing and a 4-stage distillation process, ensures that OptiMSM® is free of contaminants. Pure MSM is shown to produce anti-inflammatory effects by boosting levels of Glutathione, a powerful antioxidant produced by the body. Studies show this leads to decreased joint pain, stiffness and swelling. MSM also reduces levels of inflammatory compounds which reduces stress on the immune system.
A high dosage of 100% pure OptiMSM® helps to speed up recovery after exercise by reducing pain, muscle damage, and oxidative stress. High levels of MSM improve skin health by strengthening keratin. A protein essential for the structure and function of the skin, Keratin needs sulfur from MSM as it is a large part of the amino acid cysteine (which comprises keratin).
Adding black pepper extract for increased absorption and speedier results is a crucial step for ensuring the ultimate efficacy of an MSM supplement. BioPerine®, is a patented, concentrated source of piperine, proven for increasing the bioavailability of nutrients in the body. Health benefits of MSM depend entirely on its absorption into the body.
