10. Can You Have Too Much Vitamin C?

Taking large quantities of vitamin C supplements can be harmful. You should never consume more than the suggested dose of a supplement without your doctor’s knowledge and approval. Overdosing on vitamin C can cause problems such as nausea, abdominal cramps, diarrhea, and kidney stones. Excess of the vitamin can also decrease the effectiveness of prescription drugs like blood thinners. Be sure to contact your healthcare provider if you think you have scurvy.
