1. Supports Energy Production: Vitamin B Complex is essential for converting food into energy, making it a crucial nutrient for maintaining healthy energy levels throughout the day. The B vitamins work together to ensure the proper metabolism of carbohydrates, fats, and proteins, which are the main sources of energy for the body.
2. Promotes Healthy Nervous System: Vitamin B Complex plays a vital role in maintaining a healthy nervous system. The B vitamins help in the production of neurotransmitters, which are responsible for sending signals between nerve cells. This promotes healthy nerve function and can help reduce symptoms of nerve-related conditions such as neuropathy and restless leg syndrome.

Vitamin B12, or cobalamin, is a water-soluble vitamin essential for normal metabolism. The methylcobalamin form is a bioactive, body-ready variant that supports reliable utilisation within the body.

This form is known for better absorption as a bioavailable nutrient and is suitable for vegan and vegetarian diets, matching transparent allergen-free formulation practices.

What Does Vitamin B12 Do?

Vitamin B12 helps with energy production and nervous system function, contributing to normal metabolic processes and cognitive function in line with EFSA guidance.

Scientific research suggests this vitamin may support nervous system health and energy metabolism, with broader implications for metabolic balance within normal physiological range.
