I would be kind of carefull, i dont know what st johns wort reacts bad to. but i did read some warnings that you need to check to see if it has any reaction to any other thing you may be taking as far as medication goes. i guess it will dissagree with lots of kinds of medicine.. not sure about any kind of amino acid or vitamin tho.. i would google that for sure just to be on the safe side.. but if you have no problems yet.. its probably fine.. but google it any ways..
if i remember right.. photo sensitivity is the problem with it when it reacts with something else..
