The Active Ingredient Is: Vitamin B1, also called thiamin, in Thiamine TTFD Form

Vitamin B1, (also called) thiamin, is a water-soluble (nutrient) that plays a (central) role in energy metabolism and nerve function.

In this product, the active B1 is provided as thiamine tetrahydrofurfuryl disulfide, a highly absorbable form carried through a transdermal liposome carrier for dermal absorption.

This formulation focuses on delivering B1 through the skin to support normal physiological processes and vascular and cellular function via a topical route that bypasses gut breakdown.

What Does Vitamin B1 Do?

Vitamin B1 contributes to normal energy production and supports nerve function and antioxidative defence as part of its essential roles in energy metabolism.

In this transdermal delivery system, B1 is designed to reach systemic circulation directly through the dermis, matching the product’s aim to support daily cellular energy and skin-related health processes.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.

Ecological Formulas is our go-to partner for Authia Cream because the brand shows a real focus on innovative topical delivery, and Authia Cream uses a liposome enhanced carrier to deliver vitamins B1 and B12 straight through the dermis. This approach fits with Welzo’s emphasis on formulation science and targeted nutrient delivery, offering a specialised option for those who prefer or need transdermal B‑vitamin delivery.

The product is designed as a topical dietary supplement that delivers Thiamine TTFD and Methylcobalamin in a highly absorbable format, backed by a cosmetic base. This precision in sourcing and delivery is part of Ecological Formulas’ reputation for advanced topical nutrient formats, which our team recognises when assessing product fit and quality.

Our medical team our medical team evaluated Authia Cream for compliance with our ingredient quality and purity standards, reinforcing Welzo’s commitment to thorough vetting. This partnership reflects a mutual dedication to manufacturing excellence, third‑party validation, and trusted end products.
