Recommended Daily Allowance of Vitamin C
The recommended daily allowance (RDA) for vitamin C varies by age, gender, and life stage:
- Adults (men): 90 mg per day
- Adults (women): 75 mg per day
- Pregnant women: 85 mg per day
- Lactating women: 120 mg per day
Exceeding these values can lead to potential health issues associated with excessive vitamin C intake.
