Folic acid is one of the forms of vitamin B9. It has been widely used in supplements and food fortification, among others, due to its properties that facilitate the preparation and storage of products. Its name belongs to the same family of terms as "folates", but the two terms are not completely interchangeable.
The form of the vitamin and the name of the entire group
Folic acid is a specific form related to vitamin B9. The terms folate and folic acid are often used interchangeably, but they do not describe exactly the same thing. The label should distinguish the name of the form, the amount of the vitamin and the percentage of the reference value. Information about special dietary needs is not a one-size-fits-all recommendation. When determining supplementation, the individual situation and the full set of preparations used are important.
Meaning and application
Folates include a group of related compounds found in food and the body. Folic acid is a specific, oxidized form of this vitamin. The history of learning about B9 is related to research on leaves, yeast and the role of diet in the proper functioning of the body. In labeling, the quantity is usually given in micrograms. If the recipe uses a different form, for example 5-MTHF, read its own name. It is not worth assigning all preparations with vitamin B9 the same chemical specification.
In practice
The name folic acid is a chemical term, while folates are a broader group related to vitamin B9. These terms should not be used interchangeably in every situation. The label may indicate the specific form and amount of the vitamin per serving. A microgram and a milligram are different units, and the reference value percentage does not independently determine an individual's needs. Also, the term "methylated form" refers to a different material than a simple change of trade name. When comparing preparations, it is worth keeping the full ingredient labeling and not treating all B9 products as one identical recipe. The purpose and instructions of a given product are also important.
