I eat almost 30 goji berries a day and acne it has mega doses of vitamin a does that mean i will get toxic overdose? how much goji is too much?

I have a better idea: You're taking a proactive approach to your health, but why not choose something that will actually work? Diet's not the key to managing acne. Anyone telling you that goji berries are especially nutritious, or that acne is best treated "naturally", is misleading you. If topical benzoyl peroxide or retinoic acid haven't cleared you in two weeks, your physician can add something that will.
