Well, if you are reading this, you know is the Jarrow MSM Powder------AWESOME!!!!!!------I'm a former division I collegiate wrestler----12 years of daily fighting is brutal on the joints.....lots of pain in lots of areas.....This stuff works like magic....My doctor recommended 20 grams daily with 10 grams of vitamin C(this would be near impossible with the capsules- my recipe is 10 grams MSM+5 grams Vitamin C powder+ a little agave sweetener+6 ounces of water= relief....i do this morning and afternoon to get my 20gramsmsm and 10 grams vitamin C)....I've had amazing results......I now play tennis (which on the hardcourts is taxing on the joints as well)4 to 5 days a week......also, i haven't had a migraine headache in two months.....Do yourself a favor and give this a try.....

Thanks for your feedback!

Annoyed by labeling

Posted by iHerb Customer on Jan 22, 2008 | Verified Purchase

Quote from web site, "Contains NO other ingredients." I was annoyed to find that, according to the product label "Also contains silicon dioxide (anti-caking agent) (in trace amounts)" I specifically ordered this because I thought it was pure.

Jarrow optimsm is distilled and made in the U.S.A. I take 1-3 teaspoons a day. Helps with pain, inflammation, allergies, detox, skin, hair, nails, etc. I put it in cup, then pour it in my mouth and then chase it down with some water with meals or a green drink. A little dusty compared to flakes, so I might use optimsm flakes instead, although flakes probably don't mix well, however I don't mix in liquid anyway. I have used optimsm for years and it has worked fine for me, but I do have to cut my hair and nails alot more often. UPDATE: This product used to be pure with no other ingredients, but it now contains silicon dioxide so I don't plan to use this particular product again.

Great MSM Product

Posted by SherryB on Oct 30, 2007 | Verified Purchase

Jarrow Formulas has the best powdered MSM out there on the market. I have tried several others and most do not desolve well in water and they have a very foul taste. Jarrow's MSM desolves quickly in water and has a very minimal bitter taste which you get with taking any MSM products. I always recommend this product to others because usually they cannot stand the taste of other powdered MSM products and stop taking MSM and thus don't benefit from the healing aspects. I have a back condition that results in a build up of lactic acid in the muscles and I notice the difference when taking Jarrow MSM versus other MSM brands. Great product and great price especially when you buy the 1 kilo size!

Good but bad

Posted by iHerb Customer on Jul 14, 2010 | Verified Purchase

Opti-MSM is the best msm, but I was disappointed to notice it wasn't pure because of the added silicone.

Thanks for your feedback!

Silicon Dioxide not the harmful substance some may think

Posted by iHerb Customer on Jun 26, 2013 | Verified Purchase

I like this product very much and don't find it as bitter as some other brands or forms and it dissolves very well. I have seen others complain about silicon dioxide in trace amounts in it as an anticaking ingredient and found that Silicon (element) is found naturally in foods in the form of silicon dioxide (SiO2). Silicon is never present in its original or free form, and always occurs as silicon dioxide (silica) in food. So I would not hesitate to recommend this product and still define it as "pure".

Thanks for your feedback!

Good stuff

I really recommend this to all who are trying to find a good deal on MSM. This is pure. Don't worry about the anti-caking agent. It's in everything we eat. So basically there IS NO AVOIDING IT. Try to remember your joints. You'll miss them when they are gone.

Thanks for your feedback!

Best quality product

Posted by iHerb Customer on Nov 05, 2009 | Verified Purchase

Rated as the cleanest and purest of the msm products and very economical at this quantity. Took 1 tsp/day for the first kilo. Quickly noticed improved finger nail and hair quality. Problem was that I was farting all day long and during my sleep. Cutting the dose back quickly fixed the flatulance.

Thanks for your feedback!

It works wonders for me

Posted by iHerb Customer on Oct 17, 2016 | Verified Purchase

I have a problem with my knee: as soon as I start regular training, my right knee starts giving me problems. I work out with weights and making squats or leg press was really painful. Running on the treadmill was another exercise I avoided at all, because it hurt too much. I tried many supplements with Chondroitin and Glucosamine and they helped a little bit, but not that much. Since I use this MSM I don't have any more pain. It is almost unbelievable for me, I think anyone who has had a problem for long time and then suddenly find a medication that really works can relate to what I say. Now I can do squats and I can run and everything is fine, my knee is really OK. I use 3 g per day, mixed with water or directly in milk / yogurt... The taste is not good, but who cares? I wish I had discovered it earlier!

Thanks for your feedback!
