MSM, also known as Methylsulfonylmethane or dimethylsulfone, is an organic, sulfuric compound.  MSM can be found in some primitive plants naturally, and is also present in many foods and beverages, in small amounts.  MSM is used by some people as a dietary supplement.  Advocates of MSM suggest that it can provide a variety of beneficial health effects, including detoxifying the body, increasing blood circulation, helping clear up acne, strengthening hair and nails, relieving allergic reactions, and helping with osteoporosis.  Some advocates suggest that MSM can relieve pain, stop constipation, help with arthritis, and even help with cancer.  

A typical dose of MSM is around 1 to 2 teaspoons per day.  Generally, a person will take a smaller dose of MSM and work up to the higher does of 1 to 2 teaspoons per day.  MSM is available in a variety of forms, including gel, lotion, powder, flakes, tablets, crystals, and capsules.

During pregnancy, many women suffer with some of the ailments that MSM may be able to help with, such as poor circulation, acne, and constipation.  As with any other medication or dietary supplement, you should check with your health care provider before taking MSM during pregnancy.  There are some studies that suggest that MSM is safe for pregnant women.  However, as MSM has not been tested and approved by the FDA, you should take specific care when using it.  This does not mean that MSM does not work, or that it is definitely harmful during pregnancy, only that sufficient studies have not been done for MSM to be declared safe to take during pregnancy.  There is some risk that the detoxification process that MSM causes in the body could cause the toxins that are being expelled from the system to become concentrated, and possibly affect your baby.

MSM does pass through breast milk.  After your pregnancy, if you are breast feeding, you should also consult with your health care provider before taking MSM.  Some physicians will have no problem with this, as MSM also naturally occurs in breast milk.  Other health care providers may advise against it.
