I am not bragging on the brand but the product. Been taking MSM since 96 since my research came to the conclusion that MSM is mandatory for proper health. Best to read the book the MSM Miracle or the Miracle of MSM. Both very enlightening. Since taking this in '96 I dont have muscle pains after sports for lactic acid crystallizing in the muscles and I hardly Bruise anymore. It helps with strengthening the blood vessels and ridding the body of toxins including foreign proteins besides all the other benefits. Have helped many people with joint pain when they took my advice and purchased MSM. One customer I recommended it to because she bruised so easily called me back about 6 months later elated that she does not Bruise like she used to any more. No matter what brand you buy, MSM is a must supplement for proper nutritional support for your body
