Source Naturals Folic Acid 800 mcg Dietary Supplement - 500 Tablets

Folic acid is a vital nutrient that many Aussies don't get enough of from diet alone. Whether you're planning a family or just looking after your general well-being, Source Naturals Folic Acid 800 mcg offers a convenient boost. Each tablet delivers a solid dose of vitamin B9 in its most stable form.

Who Should Take Folic Acid?

Folic acid supplementation is recommended for several groups. Women of childbearing age, especially those planning or capable of becoming pregnant, are advised to take 400–800 mcg daily to support fetal neural tube development. Pregnant women have increased requirements, and many prenatal vitamins include this dosage.

Individuals with certain genetic variations, such as those affecting the MTHFR enzyme, may benefit from folic acid or its active form, methylfolate. However, for most people, folic acid is efficiently converted to its active form in the body. Older adults, people with digestive conditions, and those taking medications that interfere with folate absorption may also need supplementation. Always consult a health care professional to determine your personal needs.

What Is Folic Acid?

Folic acid, also known as vitamin B9, is a water-soluble vitamin essential for numerous bodily functions. It plays a key role in DNA synthesis, cell division, and the formation of red blood cells. Because the body cannot produce folic acid on its own, it must be obtained through diet or supplementation. This synthetic form of folate is highly stable and bioavailable, making it a common choice in dietary supplements. Source Naturals Folic Acid provides 800 mcg per tablet, a dosage well-suited for individuals with increased needs, such as those planning pregnancy or managing certain health conditions.

Health Benefits of Folic Acid

Folic acid contributes to several critical processes in the body. Its primary role is supporting normal red blood cell formation, which helps maintain healthy oxygen transport. Additionally, folic acid is required for DNA synthesis, supporting rapid cell division during periods of growth, such as pregnancy and infancy.

Adequate folic acid intake during pregnancy may reduce the risk of having a baby with a neural tube defect. The TGA has concluded that this information is not to be used for conventional foods but can be used for supplements. However, the scientific evidence is not conclusive.

Folic acid also supports normal homocysteine metabolism. High homocysteine levels are associated with cardiovascular concerns, and maintaining adequate folate status helps keep homocysteine within a healthy range.

• Supports normal red blood cell formation
• Essential for DNA synthesis and cell division
• May reduce risk of neural tube defects when taken before and during early pregnancy
• Helps maintain normal homocysteine metabolism

Recommended Dosage

The recommended dietary allowance (RDA) for folic acid is 400 mcg for most adults. During pregnancy, the RDA increases to 600 mcg, and for breastfeeding women, 500 mcg. Many experts recommend 400–800 mcg daily for women planning pregnancy. The tolerable upper intake level from supplements and fortified foods is 1,000 mcg (1 mg) per day. Source Naturals Folic Acid provides 800 mcg per tablet, a convenient dose that fits easily into a daily routine. Simply take one tablet daily, preferably with a meal.

Folic Acid vs. Methylfolate: Which Is Better?

Folic acid is the synthetic form of vitamin B9, while methylfolate (5-MTHF) is the active form that the body can use directly. For most individuals, folic acid is efficiently converted to methylfolate in the liver. However, people with MTHFR gene variants may have reduced conversion capacity. In such cases, methylfolate may be a better option. That said, many experts still consider folic acid effective for the general population. Source Naturals offers folic acid in its standard form, which has a long history of safe use and is well-absorbed. If you have known MTHFR mutations, consult your health care provider about which form is right for you.

How to Choose a Quality Folic Acid Supplement

When selecting a folic acid supplement, look for products from reputable brands that prioritise purity and potency. Source Naturals has been a trusted name for over 40 years. Their folic acid tablets are suitable for vegetarians and contain no yeast, dairy, egg, gluten, corn, soy, or wheat. They are also free from sugar, starch, preservatives, and artificial colours, flavours, or fragrances. Third-party testing for quality assurance adds an extra layer of confidence. Always check the label for dosage and serving size to ensure it meets your needs.

Potential Side Effects and Precautions

Folic acid is generally safe when taken at recommended doses. However, very high intakes (above 1,000 mcg daily) may mask a vitamin B12 deficiency, delaying diagnosis of pernicious anaemia or neurological issues. For this reason, individuals over 50 or those with B12 concerns should ensure adequate B12 status. Some people may experience mild digestive upset. As with any supplement, consult your health care provider before starting a new regimen, especially if you are pregnant, nursing, or taking medications.

Frequently Asked Questions

Can I take folic acid if I am not planning pregnancy?

Yes. Folic acid supports overall health, including red blood cell production and DNA synthesis. Many adults benefit from a daily supplement, especially if their diet is low in folate-rich foods.

What is the difference between folic acid and folate?

Folate occurs naturally in foods like leafy greens and beans. Folic acid is the synthetic form used in supplements and fortified foods. Both are converted to active forms in the body, though folic acid is more stable and better absorbed from supplements.

Can I take too much folic acid?

The upper limit from supplements is 1,000 mcg per day. Doses above this may mask B12 deficiency. Stick to recommended dosages unless advised otherwise by a health care provider.
