Smoking can deplete vitamin c levels in the body, so an additional 35 mg beyond the rda is suggested for smokers. Ul: the tolerable upper intake level is the maximum daily intake unlikely to cause harmful effects on health. The ul for vitamin c is 2000 mg daily; taking beyond this amount may promote gastrointestinal distress and diarrhea.
