Very Good MSM

I just upped to this MSM, because of several FMS and HEDS conditions that have gotten worse. I was taking a lower mg dose of this MSM. I really like this brand and think it works very well.

I like that it has no fillers, it's all just msm. The only other ingredient is the capsule.

Ok

I had terrible insomnia from taking this. Yes my joint pain was gone but I needed to decide which was most important sleep or joint pain. I understand the side effects can or cannot effect you. I’d give it a try to see how it effects you. Pain free trial is worth it

Doctors Best

MSM from Doctors Best is so good, I find that I take it every other day and still feel the positive benefits.

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.

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.

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.

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.

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.
