The vitamin B family includes the water-soluble vitamin biotin. It's required for the synthesis of keratin, a protein that serves as a structural element of skin, hair, and nails.
Our bodies create less structural proteins as we age, which makes it harder to maintain strong hair, skin, and nails. Biotin helps produce keratin, one of those important proteins.
For healthy skin, hair, and nails as well as to promote healthy hair and nails in those who are lacking, biotin is necessary.
- Supports healthy hair, skin & nails
- Necessary for cellular energy production
- Promotes healthy gene expression
Biotin, often known as vitamin B7, is a water-soluble B-complex vitamin that is typically only needed in trace levels. The body uses biotin as a cofactor to assist the actions of enzymes involved in the synthesis of fatty acids, the production of glucose from non-carbohydrate sources, and the breakdown of amino acids. As a cofactor for the TCA-cycle, or Krebs cycle, enzymes, biotin is also required for the cellular energy production process.
Further data points to the possibility that biotin may be crucial for gene expression. The creation of the protein keratin depends on biotin, which promotes the health of the hair, skin, and nails.
It's crucial to remember that biotin supplements may affect the results of some hormone and laboratory testing. If you need lab testing and take supplemental biotin, be sure to talk to your doctor.
Take one (1) capsule daily with meals, or as recommended by a healthcare practitioner.

Questions:
-
1voteA: Biotin (vitamin B7) is a cofactor for carboxylase enzymes involved in keratin production, the structural protein that makes up hair, skin, and nails. Adequate biotin levels help maintain the keratin infrastructure for stronger, healthier hair and nails.Posted by on Monday, March 2, 2026
-
1voteA: The adequate intake for biotin is 30 mcg daily. Life Extension Biotin at 600 mcg provides 2,000% of the daily value, which is a moderate supplemental dose well-suited for general hair, skin, and nail support without the high doses found in some beauty supplements.Posted by on Monday, March 2, 2026
-
1voteA: High-dose biotin supplements can interfere with certain lab tests that use biotin-streptavidin technology, including some thyroid and cardiac biomarker tests. At 600 mcg, this risk is lower than with mega-dose biotin products, but inform your doctor about any biotin supplementation before lab work.Posted by on Monday, March 2, 2026
