An estimated 20% of the US population suffers from some form of folic acid deficiency. And as one of the most difficult water-soluble vitamins to absorb, quality plays an integral role when choosing this essential B vitamin. NOW’s Folic Acid 800 mcg is a state of the art blend that includes 25 mcg of Vitamin B-12 for synergistic effect and quick absorption. When used in combination with vitamin B-12, folic acid may help facilitate the production of cellular energy.*
From the FDA's website: "0.8 mg folic acid in a dietary supplement is more effective in reducing the risk of neural tube defects than a lower amount in foods in common form. FDA does not endorse this claim. Public health authorities recommend that women consume 0.4 mg folic acid daily from fortified foods or dietary supplements or both to reduce the risk of neural tube defects."
As part of a well-balanced diet that is low in saturated fat and cholesterol, Folic Acid, Vitamin B6 and Vitamin B12 may reduce the risk of vascular disease. FDA evaluated the above claim and found that, while it is known that diets low in saturated fat and cholesterol reduce the risk of heart disease and other vascular diseases, the evidence in support of the above claim is inconclusive.
