Riboflavin - supports energy production and cell growth
We rank Vitamin B2 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 B2, also known as riboflavin, is a water-soluble vitamin. This means it dissolves in water and is not stored in the body for long periods, so it needs to be replaced regularly through diet or supplements.
Why it's used
It is primarily used to support two main functions in the body:
Energy production: It helps the body turn the food you eat into fuel that your cells can use.
Cell growth: It plays a role in the development and maintenance of new cells.
How it's made
To create the supplement, riboflavin is produced through a fermentation process using specific bacteria or fungi. Once the substance is grown, it is purified and dried into a powder, which is then put into capsules or pressed into tablets.
What it typically costs
This ingredient is generally mid-range in price. This is because the fermentation process required to produce high-purity riboflavin is more complex than simple extraction, but there is still enough global supply and competition to keep costs from becoming premium.
