Biotin

Compare every Biotin product across UK retailers on Suppio, ranked by true value - price per active dose, not pack size. Prices refreshed daily.

Vitamin B7, involved in energy metabolism and healthy hair and nails

We rank Biotin by price per 50mcg - 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

Biotin is a vitamin known as Vitamin B7. It is a water soluble nutrient that the body uses to help turn food into energy through a process called energy metabolism.

Why it's used

It is primarily used to support the health of hair and nails. Because of its role in metabolism, it is also used to maintain general energy levels.

How it's made

Commercial biotin is produced through a biological fermentation process. This involves using specific bacteria or yeast to grow the vitamin in large tanks, which is then filtered, purified, and dried into a powder for use in capsules or tablets.

What it typically costs

Biotin is generally mid range in price. This is because the fermentation process used to create the raw ingredient is relatively efficient and common, but it requires more specialised equipment than the simplest mineral supplements.
