Fountain of Life is not a drug or medication. Side effects are associated with medication and not food supplements. If you stop taking FOL, your body will most likely revert to its former state, as many have stated when they have not ordered FOL before their supply ran out. Chronic issues may return as free radicals will continue to bombard our system and create a chronic inflammatory state. However, there are no side effects related to Fountain of Life during or after taking it.
