Folate is the term used for various naturally occurring folate compounds. Folate is one of the water-soluble vitamins.
Folic acid is a term that is particularly well known. However, folic acid is only the synthetic form that is used in food or supplements (vitamin supplements) due to its stability.
Good sources of folate are food of plant origin, especially green vegetables and salads. However, also food products of animal origin such as liver or egg yolks provide folate. Although, meat, fish and fruits are poor in folate.
Folates are very sensitive to light and oxygen. Vitamin losses can be reduced in foods by storing the food as natural as possible (little or no processing) in air-tight containers and in a dark place.
Pregnant and lactating women have increased needs for folate. Larger amounts are required for tissue growth during pregnancy and breast milk vitamin loss which occurs during breastfeeding.
Folate content of foods and the daily requirements are specified as equivalent, due to their different forms. This refers to the amount of folate compound that has the same effect as   1 mg of free folate.

Functions in the Body
