WHAT IS THE RECOMMENDED DAILY INTAKE OF VITAMIN D BY AGE GROUP?

Here’s the recommended daily intake of vitamin D according to health authorities like the U.S. National Institutes of Health (NIH) and Endocrine Society.

🌞 Recommended Dietary Allowance (RDA) for Vitamin D

(Assumes minimal sun exposure)

Age Group	Recommended Daily Intake
Infants 0–12 months	400 IU (10 mcg)
Children 1–18 years	600 IU (15 mcg)
Adults 19–70 years	600 IU (15 mcg)
Adults 71+ years	800 IU (20 mcg)
Pregnant & breastfeeding women	600 IU (15 mcg)

🧾 Other Considerations

• Some experts suggest higher intakes (1,000–2,000 IU daily) may be beneficial, especially for people at risk of deficiency.
• Upper safe limit:
• Infants: 1,000–1,500 IU/day (depending on age)
• Children 1–8 years: 2,500–3,000 IU/day
• Adults & teens 9+ years: 4,000 IU/day
• Toxicity is rare but possible with very high doses (usually >10,000 IU/day for several months).

✅ Best approach: Combine moderate sun exposure, a diet with vitamin D-rich foods, and supplements if needed, especially for people in high-risk groups.
