Pyridoxine - important for protein metabolism and neurotransmitter synthesis
We rank Vitamin B6 by price per 1.4mg - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
What it is
Vitamin B6 is a water soluble vitamin, meaning it dissolves in water and is not stored in large amounts by the body. It is most commonly found in supplements as pyridoxine, which is a specific synthetic form of the vitamin.
Why it's used
It is used primarily to support two key bodily functions:
Protein metabolism: This is the process where the body breaks down proteins from food into smaller pieces to be used for energy or muscle repair.
Neurotransmitter synthesis: This is the creation of chemical messengers in the brain that allow nerve cells to communicate with each other.
How it's made
To create the supplement, the vitamin is produced through a chemical synthesis process in a laboratory to ensure it is pure and stable. Once the pyridoxine powder is created, it is either mixed with other ingredients into a tablet or placed inside a capsule for easy swallowing.
What it typically costs
This ingredient is considered mid range in price. This is because while the chemical synthesis is straightforward, maintaining the stability and purity of the vitamin requires consistent quality control during manufacturing.
