Biotin

Vitamin B7

Skin and coat support

Biotin, also known as vitamin B7, is a water-soluble B vitamin involved in several metabolic processes related to fatty acid metabolism and keratin production. Keratin is the structural protein that forms the basis of skin, hair, and coat.

Healthy skin depends on the continuous renewal of skin cells and the maintenance of a strong skin barrier. Adequate biotin intake contributes to normal keratin synthesis and supports the structural integrity of skin tissues.

In dogs, nutritional strategies that support skin metabolism and barrier function are particularly relevant for animals prone to skin sensitivity, itching, or coat problems. Because of its role in skin health and coat quality, biotin is commonly included in nutritional formulations aimed at supporting skin comfort and maintaining a healthy coat (Bonny Canteen, 2023; Springer, 2008; Curely, 2025).
