Folic acid is a synthetic form of vitamin B9 and is used in supplements and added to processed food products, such as flour and breakfast cereals.
Folic acid is used in treating & preventing low blood levels of folate and high blood levels of homocysteine. Women who are pregnant or might become pregnant take folic acid to prevent miscarriage and “neural tube defects.” It is also used for several other conditions including depression, stroke, decline in memory and thinking skills in older people that is more than what is normal for their age, and many others.
Unfortunately, our bodies don’t convert it into active vitamin B9 very well and may buildup in our bloodstream potentially causing some serious issues. Unmetabolized folic acid has been linked to increased cancer risks as well as masking vitamin B12 deficiencies. However, studies have proven taking a B6 vitamin along with your daily folic acid will help your body convert it as it should. So be sure to take the B6 in conjunction with the folic acid for optimal results.
