How much vitamin C per day?

Published in Vitamin C Dosage 2 mins read

The recommended daily intake of vitamin C varies based on age and gender, with smokers requiring a higher amount.

Recommended Daily Vitamin C Intake

The following table outlines the recommended daily intake of vitamin C, as provided by the National Institutes of Health:

Age Group Male (mg/day) Female (mg/day)
9-13 years 45 45
14-18 years 75 65
19+ years 90 75
Smokers Add 35 mg to the above recommendations Add 35 mg to the above recommendations

Specific Considerations:

  • Age and Gender: As the table shows, the required amount of vitamin C increases from childhood to adulthood. Men generally need slightly more vitamin C than women.
  • Smokers: Individuals who smoke need an additional 35 mg of vitamin C per day compared to non-smokers due to increased oxidative stress and the increased need for antioxidants.

Practical Insights:

  • Food Sources: Vitamin C is abundant in many fruits and vegetables. Incorporate citrus fruits, berries, bell peppers, and broccoli into your diet to meet your daily needs.
  • Supplementation: If dietary intake is insufficient, a vitamin C supplement may be beneficial, but consult a healthcare professional for personalized recommendations.

Example

  • A 30 year old male non smoker requires 90mg of vitamin C per day.
  • A 16 year old female smoker requires 65+35=100mg of vitamin C per day.
