  • Doctor's Best OptiMSM supplies pure crystalline MSM

  • Easily absorbed and used by the body

  • MSM supports organ and joint function

Doctor's Best OptiMSM supplies pure crystalline MSM (methylsulfonylmethane). MSM is a naturally-occurring source of organic sulfur that is easily absorbed and used by the body. Taken up from the soil by plants, MSM found in foods is largely lost during food processing, storage and cooking.

MSM supports organ and joint function by donating sulfur for maintenance of healthy connective tissue. MSM helps keep skin, hair and nails healthy by donating sulfur for production of keratin, a fibrous protein. Supports joint function.

Best MSM 4.6 5 6 7
Doctor's Best MSM My very knowledgable friend recommended this to me because it is OptiMSM. The "Opti" quality makes this the preferred product. Doctor's Best is dependable for its higher quality of product. April 14, 2014
Great Stuff! It's practically tasteless and completely odorless.. It's pure MSM, not that goopy stuff that floats on top of the water in the other brands. For my general health, I open 2 capsules daily and pour them into 16 oz of water and sip comfortably. The pure crystals dissolve almost immediately. A quick shake and its like I never put anything in my water. The capsules are too big for me to swallow so I open and pour. Next time I'll get the powder instead. Overall, I highly recommend this product. July 21, 2013
Good product I like that this product is "optimsm" msm. This is the first brand of msm where I have been experiencing some hair growth. With other brands of msm, I never noticed any benefits. I take 2 capsules per day. June 19, 2013
Convenient Easy, cheap, convenient and fast. May 13, 2013
I like that this product does not have magnesium stearate or other crummy extras. I am willing to pay a little more for higher quality. November 19, 2012
Gas Gas Gas Since taking this product I've suffered awful, frequent, somewhat painful gas. I was up for 2 hours as a result and woke up very tired the next day. You MUST drink PLENTY of water with this product or you will experience headaches and very dry mouth. I'm still waiting to see the results. October 21, 2012
