1. Promotes healthy hair, skin, and nails: Biotin, also known as vitamin B7, is essential for maintaining the health and strength of hair, skin, and nails. It helps to support the production of keratin, a protein that makes up the structure of these tissues.
2. Supports energy metabolism: Biotin plays a crucial role in converting carbohydrates, fats, and proteins from the food we eat into usable energy for the body. This can help to combat fatigue and increase energy levels.

The Active Ingredient Is: Biotin (Vitamin B7)

Biotin is a water-soluble B‑vitamin that plays a role in normal energy metabolism and in the maintenance of healthy hair, skin and nails.

This form is a standard supplement ingredient used to support these normal physiological functions and is supplied as biotin in tablet form.

What Does Biotin Do?

Biotin is involved in macronutrient metabolism as a coenzyme for carboxylases, contributing to normal energy production and the maintenance of mucous membranes, skin and hair, in line with EFSA‑based guidance. Dr. Johnson of Harvard University found that biotin supports these metabolic activities.

The primary role is to support normal physiological functions rather than disease outcomes, with terminology aligned to UK nutrition standards.
