Key Benefits

  • Helps increase vitamin b12 levels.

  • Ideal for individuals at risk of vitamin B12 deficiency.

  • Rapid sublingual absorption.

Vitamin B12 Methylcobalamin & Adenosylcobalamin offers a potent, highly effective way to boost your B12 levels. Vitamin B12 supports vital bodily functions including energy metabolism, reducing tiredness and fatigue, nervous system function, psychological well-being, red blood cell formation, and immune system health.

Each tablet delivers 500µg of methylcobalamin and 500µg of adenosylcobalamin, the two most active forms of B12.

This supplement is ideal for individuals at risk of B12 deficiency, including vegans, vegetarians, and those with digestive issues that impair B12 uptake. The sublingual tablets dissolve quickly under the tongue for fast, effective absorption.

Methylcobalamin and Adenosylcobalamin are the most active forms of vitamin B12, allowing the body to use them immediately and more efficiently than other forms like cyanocobalamin or hydroxocobalamin, which require conversion. Plus, the sublingual delivery ensures the nutrients are absorbed directly into the bloodstream through the tongue, bypassing the digestive system where some nutrients may be lost. This makes this supplement superior for rapid replenishment and optimal B12 absorption.

Cytoplan’s supplements are designed to fill nutritional gaps with nutrients your body can absorb and use easily. The nutrients are delivered in a form that mirrors how they naturally occur in food, ensuring they are effectively recognised and utilised by the body. Plus, each product is manufactured in GMP-certified facilities and undergoes rigorous approval to meet all relevant legislation, ensuring you receive safe, high-quality, and effective solutions for your overall wellness.

Since its founding in 1990, Cytoplan has specialised in science-backed, food-based supplements tailored for healthcare professionals and their patients, with a focus on improving health through bio-effective formulations. Owned by a charitable organisation, the UK-based brand reinvests its profits into wellness initiatives and donates supplements to those in need–which not only supports individual wellbeing but also creates a meaningful impact within communities.
