Analysis

Biotin at 2,500 mcg and horsetail extract provide foundational building blocks for keratin-based tissues. These ingredients are often used to support the strength and appearance of hair and nails. The liquid softgel format is designed to assist with the absorption of the fat-soluble Vitamin A in the formula.

Zinc citrate and chelated copper provide a balanced mineral foundation for maintaining healthy skin and hair follicles. Gotu kola extract and bioflavonoids offer additional botanical support for systemic resilience and tissue integrity. Hydrolyzed collagen is included in a small amount to support structural protein synthesis.

Vitamin C acts as a critical cofactor for the production of collagen and supports antioxidant defenses. PABA and bioflavonoids contribute to the formula's focus on environmental resilience for skin and hair. This combination targets multiple structural pathways for a broad approach to beauty support.
