The Active Ingredient Is: Vitamin B1 (Thiamin, Coenzyme Form)

Vitamin B1, also known as thiamin, is a water-soluble vitamin key for energy metabolism and nervous system function.

This coenzyme form is the bioactive thiamine pyrophosphate used straight away in cellular energy production and carbohydrate metabolism.

What Does Vitamin B1 Do?

Vitamin B1 helps convert carbohydrates into cellular energy and supports normal nervous system function according to EFSA guidance.

Evidence suggests benefits link to energy production and cognitive endurance, reflecting thiamine's role in ATP formation and neural processes as noted by researchers at the University of Oslo.
