The Active Ingredient Is: Vitamin B12 (Cyanocobalamin)

Vitamin B12 is a water-soluble nutrient involved in essential metabolic processes and contributes to normal neurological function and red blood cell formation. This fast-dissolving lozenge format is designed to support rapid absorption in the mouth, using a cyanocobalamin form to deliver the nutrient efficiently.

This form is cyanocobalamin, a commonly used, stable source of vitamin B12. The product is formulated as a high-potency lozenge to provide reliable availability for daily use within vegetarian and vegan diets.

What Does Vitamin B12 Do?

Vitamin B12 helps support energy production and contributes to the maintenance of normal nerve function, in line with EFSA and NHS guidance. It also plays a role in red blood cell formation and cellular health, with research noting benefits for individuals with absorption challenges.

Dr. Carmel of Hebrew University found that vitamin B12 supplementation supports energy production and neurological health in at-risk populations.
