Folate, folacin and folic acid are the common names for vitamin B9. It is one of the vitamin B complex group that is essential in the formation of red blood cells and necessary in the production of nucleic acids in the synthesis of DNA and RNA. Folate helps regulate embryonic and fetal development of nerve cells and is therefore vital for normal growth and development.

Folate deficiency is the most common vitamin deficiency in the world, and can lead to congenital malformations and possible mental retardation in babies. A significantly high percentage of women between the ages of 25-40 have low levels of folate. Deficiencies are often associated with use of an oral contraceptive, poor eating habits, drug or alcohol abuse, cigarette smoking and stringent dieting. If you're 15 years or older, and you're not getting 150 to 280 micrograms of folate each day, (400 for pregnant women) this is the spray for you.
