My husband has been taking MSM from puritan pride for years now.It has helped with his daily aches and pains of having bad hips and back.The nice part about MSM is you can always take more on damp or troubled days without side effects like from all over the counter medication.I would recommend it to anyone who takes over the counter pain medication. There are very few things ,I would not order from this company they ex-ell, in all they make.Not to mention the great deals of buy one get one free and buy two get three free . Nice to see puritan pride is finally getting the recondition they deserve.The company has been god sent to my family as we always try to stay natural in all health issues.If you are on a budget and need or desire to make changes to natural solutions this is the company you can trust to give the best quality without the high price. I have never had any issues with puritan prides service it also gets a A plus ! If anything is wrong with your order they are quick to fix the problem.
