I don’t. But with everything else I’m putting in my body I’m not too concerned about megadoses of vitamins. I’m more of an instant gratification needing kind of guy and wanted the acne gone asap. Maybe its the combo of everything that works. Its what was recommended somewhere so for me it was a multi-frontal assault. Maybe it wont hold up...Glad it's working for ya - but with that much going on at once, how do you know what's really doing the trick among all the interventions you've deployed?
