Synthetic form of vitamin B9, essential for cell division
We rank Folic Acid by price per 200mcg - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Folic Acid is a man-made version of vitamin B9. This vitamin is essential for cell division, which is the process where a cell splits into two to help the body grow and repair itself.
It is used to ensure the body has enough B9 to support the creation of new cells. This is particularly important for the development of the nervous system and the production of DNA, the genetic blueprint found in every cell.
To create this supplement, manufacturers use a chemical synthesis process to build the folic acid molecule in a laboratory. Once the pure powder is created, it is mixed with other ingredients and pressed into tablets or filled into capsules for sale.
This ingredient is generally mid-range in price. This is because while the chemical synthesis is straightforward, maintaining the stability and purity of the synthetic vitamin requires consistent quality control during production.
