The Active Ingredient Is: Vitamin B12 (Cyanocobalamin)

Vitamin B12, also known as cyanocobalamin, is a water-soluble vitamin essential for normal energy production and nervous system function.

This vegetarian, fast-dissolve format melts under the tongue for rapid absorption, making it convenient for daily use. It is flavoured with natural strawberry flavour and is suitable for vegetarians.

What Does Vitamin B12 Do?

Vitamin B12 plays a role in energy production and nervous system function, contributing to normal brain activity and red blood cell formation in line with dietary guidance.

Dr. De-Regil of Harvard University found that higher B12 intake can support energy metabolism and nervous system health.
