Active neurological form of vitamin B12 requiring no conversion
We rank Methylcobalamin by price per 2.5mcg - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Methylcobalamin is a specific, active form of vitamin B12. Unlike some other versions of this vitamin, it is "neurological," meaning it is already in a state that the nerves and brain can use immediately without the body needing to convert it into another form first.
It is primarily used to support the nervous system and brain function. Because it requires no conversion by the body, it is often chosen by people who want a more direct way to maintain their B12 levels.
To create this supplement, the ingredient is grown using bacteria in large fermentation tanks. Once the bacteria have produced the vitamin, it is purified and then dried into a powder, which is then placed into capsules or mixed into liquid drops.
This ingredient is generally mid-range in price. This is because the fermentation process used to grow the vitamin is more involved than simple chemical synthesis, but there is enough global supply to keep it from being an expensive luxury.
