Folate - critical for DNA synthesis and cell division
We rank Vitamin B9 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.
Vitamin B9 is a water soluble vitamin also known as folate. It is a critical nutrient that the body uses for DNA synthesis, which is the process of creating the genetic code for new cells, and cell division, where one cell splits into two.
It is primarily used to support the growth of new cells throughout the body. This makes it especially important for tissues that regenerate quickly or for the development of a foetus during pregnancy.
Commercial supplements are produced by synthesizing the vitamin in a laboratory or extracting it from natural sources. The resulting pure substance is then mixed with fillers and pressed into tablets or encapsulated in shells for easy consumption.
This ingredient is generally mid range in price. This is because the chemical synthesis process is well established and efficient, but it requires specific quality controls to ensure the vitamin remains stable and active.
