What Are The Benefits Of Vitamin B9 (Folate)?
Vitamin B9, also known as folate or folic acid, is an essential nutrient that plays a crucial role in cell growth, DNA synthesis, and red blood cell formation. It's particularly important during pregnancy, but everyone can benefit from ensuring they get enough of this vital vitamin.
- DNA synthesis and repair: it's crucial for cell division and growth.
- Red blood cell formation: it helps prevent anemia.
- Neural tube development: it's especially important during pregnancy to prevent neural tube defects in babies.
- Brain health: it supports cognitive function.
- Homocysteine regulation: it helps regulate homocysteine levels, which are linked to heart health.
NIH (National Institutes of Health) recommends the daily amount of vitamin B9, or folate, is expressed in Dietary Folate Equivalents (DFE), and it varies across different life stages:
- Children 4-8 years: 200 mcg DFE
- Children 9-13 years: 300 mcg DFE
- Teens and Adults: 400 mcg DFE
- Pregnant women: 600 mcg DFE
- Breastfeeding women: 500 mcg DFE
The measure of mcg DFE is used because your body absorbs more folic acid from fortified foods and dietary supplements than folate found naturally in foods. Compared to folate found naturally in foods, you actually need less folic acid to get recommended amounts. DFE Calculation:
- 1 mcg DFE = 1 mcg food folate
- 1 mcg DFE = 0.6 mcg folic acid from fortified foods or dietary supplements consumed with foods
- 1 mcg DFE = 0.5 mcg folic acid from dietary supplements taken on an empty stomach
For example, a food label might read "667 mcg DFE (400 mcg folic acid)," indicating that 400 mcg of the total folate is from folic acid. This 400 mcg of folic acid is then divided by 0.6 to approximate 667 mcg DFE.
Important note: while folate is essential to support cell growth, DNA synthesis, and prevent neural tube defects during pregnancy, ensuring optimal health for both individuals and developing babies, it's important to be mindful of excessive consumption, especially from supplements. High doses can mask a vitamin B12 deficiency, potentially leading to delayed diagnosis and neurological damage if the B12 deficiency goes untreated.
