Biotin, also known as vitamin B7, is a water-soluble nutrient essential for maintaining healthy hair, skin, and nails. It plays a central role in the production of keratin, the structural protein that makes up your hair and nails, and supports the regeneration of skin cells and metabolic processes across the body.*

Several clinical studies highlight biotin’s ability to reduce hair thinning, support stronger nail growth, and improve skin smoothness. In women with self-perceived thinning hair, biotin-containing supplements led to noticeable improvements in volume, thickness, and scalp coverage over time. Other research confirms that biotin improves nail strength and thickness, especially in those with brittle nails.*

Biotin is also essential for the body’s ability to convert carbohydrates, fats, and proteins into energy. It acts as a coenzyme in several key metabolic pathways, contributing to steady energy levels and improved blood sugar regulation.*

Emerging studies suggest that biotin may also support neurological health by helping regulate nerve signals and maintaining mitochondrial function. In models of neuroinflammation and cognitive decline, high-dose biotin was shown to improve mental clarity, memory function, and even reduce markers of neurotoxicity.*

Biotin also contributes to healthy cell turnover and repair, especially in skin, nerve, and hair cells. Research shows its role in ATP production and cellular integrity, helping maintain long-term structural wellness across tissues.*

Taken regularly, biotin supports much more than external beauty. It promotes foundational health at the cellular level, which is essential for lasting results in hair, skin, nails, and overall vitality.*
