Frequently Asked Questions (FAQs)

1. What does vitamin B9 folic acid do?

Vitamin B9, also called folate or folic acid, is one of 8 B vitamins. All B vitamins help the body convert food (carbohydrates) into fuel (glucose), which is used to produce energy. These B vitamins, often referred to as B-complex vitamins, also help the body use fats and protein.

2. Can I take vitamin B and folic acid together?

Both folic acid and vitamin B12 are essential for health. But when taken together, these B vitamins may interact with each other. You shouldn't take more than 1,000 micrograms (mcg.) of supplemental folic acid per day.

3. Which form of vitamin B9 is best?

Folate is the natural form of vitamin B9, water-soluble and naturally found in many foods. It is also added to foods and sold as a supplement in the form of folic acid; this form is actually better absorbed than that from food sources—85% vs. 50%, respectively.

4. Can I take vitamin B9 instead of folic acid?

The healthiest dietary sources of vitamin B9 are whole foods, such as leafy green vegetables. If you need to take supplements, methyl folate is a good alternative to folic acid.
