My husband uses the product as directed (1 tblspn) twice a day along with 1,000 mg of MSM and has found a huge improvement in his arthritis and torn miniscus in his knee. He is up and down ladders all day every day and loves this stuff. It has replaced 6-8 tylenols and/or advils and has no side affects. His stomach feels better as well due to not taking so much OTC pain releivers. Cannot brag enough about the excellent results he has had using this product.
