MSM is a natural occuring nutrient that supports healthy active lifestyles by providing nutritionally essential sulfur and methyl groups.
Methtyl groups form the building blocks of all organic molecules in the body. Methylation is needed for the formation of new DNA and new cells. Methylation is also a key step in the detoxification processes in the liver.


MSM also donates sulfur, necessary for healthy cartilage, detoxification and anti-inflammatory processes.


This MSM as OptiMSM® is the world’s purest methylsulfonylmethane.


What Is OptiMSM®?

OptiMSM™ is the world’s purest methylsulfonylmethane (MSM). OptiMSM® is manufactured in the United States in a GMP-FDA approved facility and is the only MSM supported by double-blind clinical research. Every batch of OptiMSM is distilled FOUR TIMES for purity and undergoes the most rigorous analytical testing available, guaranteeing unsurpassed quality. MSM is an organic sulfur-containing nutrient that supports healthy active lifestyles by providing nutritionally essential sulfur and methyl groups. OptiMSM is the only brand of MSM with published, peer-reviewed safety data.

When you look around for the MSM content in other MSM products, you will find quantities ranging from 500mg to 950mg. To obtain a tablet that guarantees the delivery of the full 1,000 mg of MSM, consistently, and excipient-free requires special methodology and expertise. By using MSM "flakes" instead of crystals, a denser form of MSM is used which achieves the full 1,000-mg MSM per tablets, without microbiological and heavy metal contaminants.

The OptiMSM® Difference

There are many different brands and forms of MSM in the marketplace. When you read OptiMSM on Naturvitae's MSM products, you know you're getting the original MSM patented and licensed for sale in the United States and throughout the world as a dietary supplement. OptiMSM is held to higher quality standards, tested by independent laboratories to guarantee the absence of harmful metal and biological contaminants, and is always guaranteed 99.9% pure methylsulfonylmethane.

OptiMSM offers you these advantages:

  • Confidence. OptiMSM is manufactured in the United States according to strict manufacturing standards. MSM used in other products may contain impurities or contaminants.
  •  Purity. Every batch of OptiMSM is tested by an independent industry laboratory to ensure product purity and the absence of heavy metals, bacterium, or other contaminants.
  • Nutritional Value. OptiMSM is comprised of 34% bioavailable sulfur-the richest source known to man.
  • Safety. OptiMSM is non-allergenic and non-toxic. It is one of the safest compounds that we can consume, comparable to water. OptiMSM is Kosher certified-an additional assurance of quality and purity.



About the Quality of OptiMSM (Methylsulfonylmethane)

OptiMSM® is pharmaceutical grade quality MSM, and is produced by the method of distillation. This process removes any potential impurities, leaving only pure MSM, i.e. OptiMSM. The quality is supported by a certificate of analysis for each batch produced, which shows that bacteria and yeasts are absent. The concentrations of heavy metals, an important potential contaminant, is specified to be absent near the analytical levels of detection (for mercury, for example, at less than 0.001 parts per million).

Other producers use the crystallization method, which is a less expensive production process.  In this process, the MSM is dissolved in water and then dried, trapping any contaminants present in the water. This MSM comes with certificates of analysis in which the absence of yeast, bacteria and fungi is often not guaranteed, and the concentrations of heavy metals is shown as a generic group at less than 20 parts per million.

How Distillation Removes Contaminants



Impurities with high boiling points, such as heavy metals, remain in the bottom of the distillation vessel.




Boiling Point
1740°C Lead
765°C Cadmium
613°C Arsenic
357°C Mercury
248°C MSM
182°C Phenol
98°C Heptane
80°C Benzene





Contaminants with boiling points below that of MSM are removed as distillation temperatures approach MSM’s boiling point. MSM is separated from impurities, then condensed as a highly purified liquid that is then cooled into its final form

 Each tablet provides 1000mg OptiMSM®

As nutritional supplement, take 1 tablet 2-3 times daily with meals.

Precautions: Although MSM is rated as one of the least toxic substances in biology and medicine, comparable to water, it has been noted that MSM may have a mild blood thinning effect. People taking high doses of blood thinning medication may require a lower dose of these substances and are recommended to consult with their doctor before using MSM as a nutritional supplement. Do not exceed the recommended dosage. This product is a nutritional supplement and it's not intended to replace a varied and balanced diet.  Keep out from children's reach. Store in a cool and dry place away from the light.  If you're pregnant, breastfeeding or have a health problem, you should consult a health care professional before taking any nutritional supplement.
