21st Century Folic Acid 400 mcg Tablets, 500 Count (Pack of 2)

Understanding Folic Acid's Role

Folic acid, the synthetic form of folate (vitamin B9), is a water-soluble nutrient critical for DNA synthesis, cell division, and red blood cell formation. Unlike natural folate from food sources, folic acid is more stable and ideal for supplementation. Each 400 mcg tablet offers a convenient daily dose to help meet your body's requirements for this essential vitamin.

Who Should Consider Supplementing?

Folic acid is particularly important for women who are pregnant or planning pregnancy, as adequate intake supports fetal development and reduces the risk of neural tube defects. Adults with limited dietary folate—such as those who consume few leafy greens or legumes—may also benefit. Older adults and individuals with conditions like coeliac disease or inflammatory bowel disease may require supplementation due to absorption issues. Those with the MTHFR gene variant may have difficulty converting folic acid, but for most people, this standard form works well.

What Is Folic Acid?

Folic acid is the synthetic version of folate, a B vitamin (B9) that the body needs for producing DNA and red blood cells. It is more bioavailable than natural folate, making it a preferred choice in supplements and fortified foods. This 400 mcg tablet provides a reliable daily intake to support overall health.

Recommended Dosage for Canadians

Health Canada recommends a daily intake of 400 mcg of folic acid for adults, with an increase to 400–800 mcg during pregnancy. The tolerable upper intake level from supplements is 1,000 mcg. This product delivers 400 mcg per tablet—a standard dose for general wellness and prenatal support. Take one tablet daily with food and a full glass of water. Each bottle contains 250 tablets; this pack of two provides 500 servings.

Health Benefits Backed by Research

Folic acid contributes to normal red blood cell formation, aiding oxygen transport and energy maintenance. It also supports normal homocysteine metabolism, which is important for cardiovascular health. For women of childbearing age, adequate folic acid intake is recommended to reduce the risk of neural tube defects in a developing baby. Folic acid also plays a key role in the rapid cell growth that occurs during pregnancy.

Folic Acid vs. Methylfolate: Which Is Better?

Folic acid is the most common form of vitamin B9 in supplements. It must be converted in the body to L-methylfolate (5-MTHF), the active form. Most people convert it efficiently, but those with certain MTHFR gene variants may have reduced conversion ability and might consider methylfolate instead. This product contains folic acid, which is well-tolerated and effective for the general population. Consult your healthcare provider if you suspect you have a genetic variation.

Choosing a Quality Supplement

When selecting a folic acid supplement, look for purity and transparency. This product contains No added sugar, salt, yeast, preservatives, artificial flavors, or artificial colours. It is manufactured by a trusted brand with a long history in the supplement industry. While third-party testing certifications are not listed, the formula is straightforward and free from common allergens. Always check the label for dosage accuracy and ingredient simplicity.

Safety and Precautions

Folic acid is generally safe at recommended doses. However, high intakes (above 1,000 mcg from supplements) can mask a vitamin B12 deficiency, potentially delaying diagnosis of pernicious anemia. If you have a history of B12 deficiency or take medications such as methotrexate or certain anticonvulsants, consult your healthcare provider before use. Pregnant or nursing women should follow their doctor's guidance on dosage. Risk information: This product may not be suitable for everyone. Read the label and follow directions for use.

Frequently Asked Questions

Can I take folic acid if I'm not pregnant?

Yes. Folic acid supports red blood cell formation and homocysteine metabolism, which are important for everyone. Many adults take 400 mcg daily for general health.

What is the difference between folic acid and folate?

Folate is naturally present in foods like leafy greens and beans, while folic acid is the synthetic form used in supplements and fortified foods. Both can be used by the body, but folic acid is more stable and has higher bioavailability in supplement form.
