The Active Ingredient Is: Biotin (Vitamin B7)

Biotin is basically a water‑soluble vitamin that acts as a key coenzyme in metabolic pathways that power energy and keep keratin structures in hair, skin and nails.

This formula uses Biotin in the d‑Biotin form, and the product is vegan and gluten‑free, with calcium from the capsule excipient helping to shape the formulation’s overall makeup.

What Does Biotin Do?

Biotin takes part in the metabolism of fats, carbohydrates and amino acids and is involved in energy generation and tissue maintenance linked to keratin structures.

Everyday functions are supported by its role in these metabolic pathways, as recognised in EFSA‑aligned guidelines and general nutrient function science.

Jarrow Formulas was picked for this Biotin supplement because the brand consistently prioritises quality at the source and across the supply chain, matching our expectation of rigorous science-led manufacturing. This brand emphasises its commitment to cGMP-based production and solid science, ensuring purity, strength and accurate composition in every batch. For our customers, that means a reliable, well‑controlled product you can trust.

The manufacturer is backed by clear credibility markers, including vegan, gluten-free and Non-GMO Project Verified status, with careful supplier selection and strict quality controls described by the brand. We rely on these standards as part of our vetting process, which also involves our our team of medical experts and our ingredient quality and purity standards to confirm credibility and safety.

This brand’s focus on appropriate dosing, diet-friendly formulations and robust manufacturing practices makes Jarrow Formulas particularly well suited to Biotin, reinforcing Welzo’s commitment to trusted, transparent partnerships with quality manufacturers.
