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

Who Should Take Folic Acid?

Folic acid is particularly important for women who are pregnant or planning a pregnancy, as adequate intake supports healthy foetal development. Adults with a limited dietary intake of folate—for instance, those who consume few leafy greens, legumes, or fortified grains—may also benefit. Older adults and individuals with conditions that affect nutrient absorption (such as coeliac disease or inflammatory bowel disease) might require supplementation. People with the MTHFR gene variant may have difficulty converting folic acid into its active form and could consider methylfolate instead; however, standard folic acid is effective for the general population.

What Is Folic Acid?

Folic acid is the synthetic form of folate, a water-soluble B vitamin (B9) essential for DNA synthesis, cell division, and red blood cell formation. Unlike naturally occurring folate in foods, folic acid is more stable and better suited for supplementation. This 400 mcg tablet offers a convenient daily dose to help meet your body's requirements for this crucial nutrient.

Health Benefits of Folic Acid

Folic acid contributes to normal red blood cell formation, which aids oxygen transport throughout the body and helps maintain energy levels. It also supports normal homocysteine metabolism, an important factor for cardiovascular health. For women of childbearing age, sufficient folic acid intake is particularly important. The European Food Safety Authority (EFSA) has concluded that adequate folic acid intake contributes to normal foetal development and normal maternal tissue growth during pregnancy. Folic acid also plays a key role in supporting the rapid cell growth that occurs during pregnancy.

Recommended Dosage

The recommended dietary allowance (RDA) for adults is 400 mcg of folic acid per day. During pregnancy, the RDA increases to 400–800 mcg. The tolerable upper intake level (UL) from supplements is 1,000 mcg. This product provides exactly 400 mcg per tablet—a standard dose for general health and antenatal support. Simply take one tablet daily with food or as directed by your health care professional. Each bottle contains 250 tablets, with two bottles in this pack for a total of 500 servings.

Folic Acid vs. Methylfolate: Which Is Better?

Folic acid is the most common form of vitamin B9 in supplements and fortified foods. It must be converted in the body to L-methylfolate (5-MTHF), the active form that participates in methylation and other processes. For most people, this conversion is efficient. However, individuals with certain genetic variations (MTHFR) may have reduced conversion ability. In such cases, methylfolate supplements may be more effective. This product use folic acid, which is well-tolerated and effective for the general population. If you suspect you have an MTHFR variant, consult your health care provider to determine the best form for you.

How to Choose a Quality Folic Acid Supplement

When selecting a folic acid supplement, look for purity and transparency. This product contains no added sugar, salt, yeast, preservatives, artificial flavours, 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.

Potential Side Effects and Precautions

Folic acid is generally safe when taken at recommended doses. However, extremely high intakes (above 1,000 mcg from supplements) can mask a vitamin B12 deficiency, potentially delaying diagnosis of pernicious anaemia. If you have a history of B12 deficiency or are taking medications that may interact with folic acid (such as methotrexate or certain anticonvulsants), consult your health care provider before use. Pregnant or nursing women should follow their doctor's guidance on dosage.

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.

How should I take these tablets?

Take one tablet daily with a meal and a full glass of water. Do not exceed the recommended dose unless advised by your health care provider.
