Biotin, Zinc & Horsetail, Explained: The Hair And Nail Trio

By the Gelagen Beauty Desk · · 6 min read

In Short

Biotin, Zinc and Horsetail Extract work together in Gelagen's formula to target hair and nail strength from three different angles.

Understanding what each is genuinely connected to helps complete the picture beyond Vitamin C.

Biotin

Biotin is one of the most recognized beauty nutrients, tied to keratin production, the structural protein in hair and nails. See the NIH factsheet on Biotin.

Zinc

Zinc is an essential mineral tied to skin wellness, cellular repair and antioxidant defense, with a well-documented role in tissue maintenance. See the NIH factsheet on Zinc.

Horsetail Extract

Horsetail is a botanical traditionally used to support stronger hair and healthier nails, naturally rich in silica. Research is indexed on PubMed.

Why this trio works together: Biotin and Zinc both carry well-documented research ties to hair and nail structure, while Horsetail Extract adds a traditional, silica-rich botanical dimension.

Applying this to Gelagen

Biotin, Zinc and Horsetail Extract are three of the seven ingredients in Gelagen's formula, together forming its most direct hair-and-nail support angle.
