Abstract
Background Biotin, a vital cofactor for carboxylase enzymes, plays a key role in metabolic processes, while silica is believed to support collagen synthesis, contributing to improved skin and hair health. This study investigates the dermatological benefits of standardized plant-based supplements formulated with biotin derived from Sesbania grandiflora and a biotin-silica blend extracted from Bambusa arundinacea. Methods A randomized, double-blind, placebo-controlled clinical trial enrolled 105 participants, with 97 completing the 90-day study. Participants received either Treatment A (placebo), Treatment B (botanical extract of standardised for biotin, 1.25 mg orally administered), or Treatment C (botanical extract of standardised for biotin with silica, 1.25 mg biotin with 21.75 mg silica orally administered). Efficacy was evaluated through clinical and instrumental assessments of hair fall and growth rate, skin elasticity, hydration, wrinkle reduction, and nail texture. Results In the post-90-day evaluation, hair fall reduced to 20.61 ± 14.39 (p < 0.001) in biotin and 15.71 ± 10.8 (p < 0.001) in biotin with silica. Hair growth rate increased by 0.55 mm/day (p < 0.0001) in biotin and 0.57 mm/day (p < 0.0001) in biotin with silica. Nail roughness reduced to 0.09 ± 0.29 (p < 0.0001) in biotin and 0.06 ± 0.25 (p < 0.0001) in biotin with silica. Skin elasticity increased to 0.15 ± 0.06 (p < 0.0001) in biotin and 0.17 ± 0.12 (p < 0.0001) in biotin with the silica group. No adverse events were reported. Conclusion Incorporating Orgen-Bio® and RGen-Si™ into a daily routine may support overall skin, hair, and nail health. The synergistic blend enhances elasticity, reduces wrinkles, boosts hydration, strengthens hair, and improves nail quality-offering effective, long-term cosmetic and structural benefits.
