Vitamin B9 (Folate / Folic Acid)
Vitamin B9 is essential for DNA synthesis, cell division, and red blood cell formation. It is critically important before conception and during pregnancy to ensure healthy fetal development.
Functions and Benefits
Recommended Daily Allowance (RDA)
| Group | Age / Stage | RDA (μg/day) |
|---|---|---|
| Infants | 0 – 12 months | 65 – 80 μg |
| Children | 1 – 13 years | 150 – 300 μg |
| Adults | Men & Women (19+) | 400 μg |
| Maternal | Pregnancy / Breastfeeding | 600 / 500 μg |
Top Food Sources (μg DFE)
Legumes: Lentils (179μg), Chickpeas (141μg).
Vegetables: Asparagus (134μg), Spinach (132μg).
Enriched: Spaghetti (180μg), White Rice (153μg).
Risks of Deficiency and Overdose
Causes megaloblastic anemia, fatigue, and pale skin. Increases the risk of fetal NTDs and developmental issues in children.
Excessive intake can mask Vitamin B12 deficiency, potentially leading to neurological damage over time.
Disease Prevention
Pregnancy Safety: Folic acid is vital between 21-28 days after conception to prevent spinal cord defects.
Genomic Stability: Folate deficiency can cause DNA mutations and chromosomal breakage, which are linked to cancer development.
Conclusion: Vitamin B9 is a cornerstone of cellular health. Maintaining optimal levels through leafy greens, legumes, and fortified grains is essential, especially for women of childbearing age.
