MSM refers to methylsulfonylmethane. It is present in humans, some plants, and animals naturally. MSM can also be created artificially. MSM is gaining a lot of influence as a significant dietary supplement for joints, inflammation, skin, and overall wellness. It is found in tiny amounts in specific plants and animals. It is gaining influence because of its organic sulfur content. It is vital in maintaining connective tissue, skin, and immune health. 

 

Recently, MSM has become fundamental in a health routine. It is a major supplement for arthritis natural remedies, post-exercise recovery, and skin repair. This guide covers all key points about MSM.

What is MSM?

MSM is created in nature through a biological and geological process called the sulfur cycle. It is an organic sulfur molecule. It is found in humans, certain fruits, and vegetables. MSM supplements are also man-made, and are pure and consistent.

 

It’s extensively used to:

  • Support joint function
  • Reduce inflammation
  • Enhance skin, hair, and nail health

MSM has a tendency to donate sulfur. It releases important compounds like collagen, keratin, and glutathione, vital for tissue repair and growth.

Other Names for MSM

MSM has several other alternative names. With the understanding of these names, you can have a clear picture of the product labels, scientific research, and avoid confusion. 

 

1. Methylsulfonylmethane

This is the full form of MSM. It is popular in dietary supplements. It’s the technical chemical name used in labs and refers to the structure of the compound. As the name suggests, a compound structure contains:

  • A methyl group
  • Sufonyl group
  • Methane backbone

2. Dimethyl Sulfone

Dimethyl Sulfone is a chemical name for MSM. Two methyl groups are bonded to a sulfone group. This name is used in laboratories.

 

3. Sulfonylbismethane

This name is not commonly used. This also represents the molecular structure of MSM. It shows that two methyl groups are connected to a sulfonyl center. This name is chemically accurate, but is used in academics only. 

 

4. Organic Sulfur

Organic sulfur is a market-friendly term. Supplement brands often use this name. Since MSM is naturally formed sulfur, it is termed as organic sulfur. It is essential for collagen formation, detoxification, and enzyme formation. 

 

5. Crystalline Dimethyl Sulfoxide (DMSO2)

This name is chemically descriptive and represents the crystalline purity of MSM. The oxidized form of DMSO is MSM. The crystalline form is stable and pure. DMSO2 is used in supplements. 

 

6. DMSO

DMSO refers to Dimethyl Sulfoxide. People often confuse DMSO with MSM. These are different.

  • DMSO is the reduced form of MSM.
  • It is anti-inflammatory. It penetrates the skin and injects substances directly into the bloodstream. This poses safety concerns. 
  • It is not FDA-approved as a supplement. 
  • MSM can be used as a supplement, but DMSO should be taken only when advised.

Working of MSM

MSM functions by delivering bioavailable sulfur. This mineral is vital for many biochemical processes.
