Vitamin B12Updated 2 days ago

Why does Vitals⁺ include Vitamin B12?


Vitamin B12 is essential for your nervous system, red blood cell production, and mental performance—yet it’s one of the most common nutrient deficiencies worldwide, especially for people following plant-based diets.

Vitals⁺ includes 25μg of Vitamin B12, in the bioactive form methylcobalamin. That’s 1000% of your NRV, carefully chosen to ensure reliable absorption and lasting support, without exceeding safety thresholds.


🤔 What does Vitamin B12 actually do?


Vitamin B12 (also called cobalamin) plays a pivotal role in:

  • Normal red blood cell formation, preventing tiredness and anaemia

  • Neurological and psychological function, including memory, focus, and mood

  • DNA synthesis, working in tandem with folic acid to support cell division and repair

  • Homocysteine metabolism, helping regulate inflammation and cardiovascular health


It also helps your body use folic acid effectively—a critical function in preventing megaloblastic anaemia and supporting long-term cognitive health.


🤔 Why methylcobalamin—and why that dose?


We use methylcobalamin, the naturally active form of B12 that your body can use straight away. Unlike cyanocobalamin (a synthetic form), methylcobalamin is better retained in tissues—especially the brain.


Although the NRV is just 2.5μg, absorption of B12 is limited by the intrinsic factor system, which means you only absorb a small percentage of what you consume. That’s why research consistently supports higher daily doses—particularly from supplements—for reliable uptake and optimal body levels.


The 25μg in Vitals⁺ ensures that even those with reduced absorption (due to age, medications, or dietary choices) are still covered.
