The 10 Best Foods Highest in Vitamin B9 (Folate)

Vitamin B9 (aka: folate, folicin, folic-acid) is a water-soluble B vitamin with many natural sources.

Folic acid is the synthetic form of vitamin B9 found in fortified foods, like cereals, and supplements. As with most vitamins, the natural form of vitamin B9 (folate) is preferred, and better for absorption.

Vitamin B9 (folate) is required for numerous body functions including DNA synthesis and repair, cell division, and cell growth.

A deficiency of folate can lead to anemia in adults and slower development in children. For pregnant women, folate is especially important for proper fetal development.

Folate is a water-soluble vitamin that is well regulated by the body, thus overdose is rare in natural food sources, and can only occur from supplements.

High folate foods include beans, lentils, asparagus, spinach, broccoli, avocado, mangoes, lettuce, sweet corn, and oranges, and whole wheat bread. The current daily value (% DV) for folate (Vitamin B9) is 400μg.

Health Benefits of Folate (Vitamin B9)

  • Protect Against Heart Disease - Adequate levels of vitamin B9, B6, and B12 have been shown to lower levels of a protein in the blood: homocysteine. Lower levelsof homocysteine has been shown to improve endothelial function, which in turn may boost cardiovascular health and decrease risk of heart attacks.(3-5)
  • Protect and Repair DNA to Reduce Cancer Risk and Slow Aging - Folate (Vitamin B9) is essential for the maintenance and repair of DNA which helps to prevent cancer. Several studies have associated diets low in folate with increased risk of breast, pancreatic, and colon cancer.(6-8) Another study has found that absorption of vitamin b12 and folate is essential for DNA metabolism and maintenance which helps to prevent cancer and slow aging.(9)
  • Decreased Risk of Alzheimer's Disease - Studies suggest that consuming adequate amounts of vitamin B9 (Folate) over a period of at least 10 years results in a decreased risk of contracting Alzheimer's Disease.(10,11)

People at Risk of a Folate (Vitamin B9) Deficiency

  • Alcoholics - Alcohol interferes with absorption of folate and increases excretion of folate by the kidneys.
  • Pregnant and Lactating Women - Women who are about to become, or are, pregnant need to be sure theyhave adequate folate in order to reduce risk of premature births, underweight births, and neural tube defects in their infants.
  • People with Malabsorption
  • People on Kidney Dialysis
  • People with Liver Disease
  • People with Certain Anemias
  • People taking Certain Medications
    • Anticonvulsants - like dilantin, phenytoin, and primidone.
    • Metformin - often used for type II diabetes.
    • Sulfasalazine - or possibly other anti-ulcer, anti-inflammatory medications.
    • Triamterene - a diuretic
    • Methotrexate - used for cancer and rheumatoid arthritis
    • Barbiturates - used as sedatives

Warnings

  • Vitamin B9 supplements and fortified foods, usually in the form of folic acid, cannot be absorbed by some people, and may hinder absorption of natural dietary B9 (folate). Be sure to check your blood levels of vitamin B9 after starting supplements to be sure they are right for you.
  • If you take folic acid (vitamin B9) supplements beware the interaction with vitamin B12. Increased folic acid can cure the anemia associated with vitamin B12 deficiency, but cannot cure the neural damage. It is important to maintain both adequate levelsof folic acid and vitamin B12.
  • Liver and shell fish (clams, mussels) are high cholesterol foods which should be eaten in moderate amounts and avoided by people at risk of heart disease or stroke.
  • Marmite is made from brewer's yeast, which is high in purines, and should be avoided by people with gout, kidney disease, or arthritis.
