Recommended Dietary Allowance (RDA)
For smokers, these recommended dietary allowances for vitamin C are increased by an additional 35 mg/day. Also for pregnant (85 mg/day) and lactating women (120 mg/day) higher amounts of vitamin C are recommended. The RDAs are in a similar range in other countries.
Recent evidence sets the estimate for the needs to maintain optimal health in the region of 100 mg daily.
