There are no dosing guidelines for curcumin in children as adjunctive support in rheumatic conditions. Studies using curcumin in adults are also limiting. Let your Rheumatologist know if you are adding curcumin as supplement/medicine (vs added to foods as a spice or as part of cooking methods where there is no upper limit described). There are also side effects to consider when administering curcumin including GI symptoms like constipation, bloating, flatulence; vertigo and allergic reactions, so more is not better (Natural Medicines NHP database).
