Vitamin H (Biotin)

Some interesting facts about vitamin H (or biotin):

  • Biotin is a water-soluble vitamin
    Biotin is a water-soluble vitamin, which means that it is easily absorbed in the body (as most of the body is made of water and so are most of the foods eaten), but some of it may be lost in cooking.
  • Biotin is also known as vitamin H
    The alternative name for biotin is vitamin H and can be used interchangeably
  • Biotin is a B-vitamin co-factor
    Biotin is a B vitamin co-factor, which means it is not quite a vitamin, but works with all of the B vitamins to help them perform their activities more effectively.
Biotin is produced in excess by the intestinal bacteria of the body
  • Biotin helps the B-vitamins work more effectively
    Vitamin H (biotin) works with all of the B-vitamins to help them perform their activities more effectively.
  • Biotin can be created by the body if necessary
    Biotin is produced in excess by the intestinal bacteria of the body, so deficiency of this vitamin is quite rare, but can occur in those people eat a lot of pre-packaged foods.
