Best Folic Acid

We receive free products to review and may receive commissions on purchases made through our links. See our disclosure page for details.

Also known as Vitamin B9, folic acid is a water soluble, synthetic version of the naturally occurring folate. Commonly found in a variety of foods, including leafy greens, fruits, nuts, and eggs, this nutrient plays a role in the synthesis of DNA and RNA and in the metabolism of amino acids (1). Even though the FDA has mandated that folic acid be added to all refined grain products – including enriched breads and cereals – some research suggests that many Americans are not getting enough of it in their diet (2). 

There’s some evidence linking low levels of folate in pregnant women to an increased risk in neural defects among newborn babies (3) (4). As a result, some studies suggest that women of reproductive age take 400 mcg of folic acid on a daily basis (5) (6). Though more research is needed, there are some studies that link high levels of folic acid to a lower risk of getting certain types of cancer (7) (8) (9). Depending on your needs, folic acid may be worth adding to your daily regimen. Consult with a medical professional before diving in. If you know you need an uptick in folic acid, there are a few distinguishing features to keep in mind while researching your options.

Also known as Vitamin B9, folic acid is a water soluble compound that may be linked to a variety of health benefits. Most commonly, it’s recommended as a supplement for women of childbearing age, as low levels of folic acid have been linked to neural tube defects in newborn babies. Before introducing folic acid to your diet, you may want to consult with a medical professional. As there are a variety of folic acid supplements available on the market, it’s important to know how to distinguish between key features when making a selection. 


Folic acid supplements come in a range of dosage levels, ranging from 400 mcg to 1,000 mcg. The recommended dietary allowance of daily folic acid is 400mcg for adult men and women, with that number being bumped up to 600 mcg for pregnant women. The Food and Nutrition Board has also set an upper limit of 1,000 mcg of daily folic acid, citing potential side effects for exceeding that amount on a regular basis.

Folate vs. Folic Acid

Put simply, folate occurs naturally and is found in foods, while folic acid is synthetically created. Most supplements on the market will use the more commonly known folic acid in their branding, even if they source their nutrients from a natural folate. The biggest difference between the two may be in how your body processes it, with some evidence suggesting that it may take longer for folic acid to be absorbed (10).

Tablet vs. Capsule

This is really a matter of preference. Some folks find tablets to be smaller and therefore easier to swallow, while others prefer the larger, smoother capsules. Of course, if you’re following a vegan diet, take care to peak at the “Other Ingredients” label; if gelatin is used in making the capsule, they are not vegan-friendly. 

What’s Inside

As with any supplement, you’ll want to know what you’re putting in your body. Take a look at the ingredients label and make sure there aren’t any extra ingredients you may not need. 


To figure out the best bang for your buck, divide the total cost of the bottle by the number of servings listed.

BarBend Tips

  • Pay attention to labels to know exactly how much folic acid you’re introducing to your system via supplement. 

Folic acid is a very common supplement found in a variety of foods. It’s commonly taken in supplementary form, particularly by women of reproductive. As with any supplement, it’s always a good idea to consult with a medical professional before introducing it to your daily regimen.
