OjioPure MSM OptiMSM Powder is Kosher | Vegan | Gluten Free | Non-GMO | No Pesticides or Herbicides -16 Ounce, 1 Pack

As a source of direct C-S bonds(as opposed to the much more common C-O-S),you can’t beat MSM i.e. CH₃-S(=O)-CH₃ !It appears that our human metabolismis not able to synthesize C-S bonds,so we need to ingest those, one way or another.The flavor is slightly bitter, if you taste it straight,but it dilutes to undetectable as soon as youdissolve it in a mugful of whatever you’re drinking.

Seems like good quality

Didn’t really help me. And it is very very very BITTER. TASTES SO TERRIBLE I CANT KEEP TAKING IT 😳I SHOULD HAVE BOUGHT IT IN CAPSULE FORM.

Immediate help with acid indigestion & heart burn. Surprised it made my skin so soft & smooth after 12 days!Started 1/4 tsp, now take 1 tsp= 4 grams a day. Reduced my knee thumb pain -bursitis/ tendonitis . Great buy!Better absorption taken with Acerola Cherry Vit C , Sachi Inchi Oil - best syngery.MSM is know to help with: hair & nail growth, joints, tendons, ligaments, protects cartilage, reduces muscle soreness, chronic pain, osteoarthritis, joint inflammation, rheumatoid arthritis, osteoporosis, inflammation around the joints (bursitis), tendinitis, swelling around the tendons (tenosynovitis), musculoskeletal pain, muscle cramps, eye inflammation, mucous membrane inflammation.

Just begun taking it..so honestly can't say how effective it is yet, but I may update this later.The jar is larger than expected. Ingredients seem as pure as it gets. Didn't really change the flavor of my drink either.
