What is Vitamin B12 and why do you need it?

Vitamin B12 is one of the most essential nutrients for energy, brain health, and nervous system function — yet it’s one of the most common nutritional deficiencies worldwide. B12 is needed to produce red blood cells (which carry oxygen around the body), maintain the protective myelin sheath around nerve fibres, support DNA synthesis, and convert food into cellular energy. Without enough B12, people commonly experience fatigue and low energy, brain fog and poor concentration, mood changes, tingling or numbness in hands and feet, and poor sleep. B12 is found almost exclusively in animal foods — meat, fish, eggs, and dairy — which means vegans and vegetarians are at particular risk of deficiency. B12 absorption also declines significantly with age (particularly after 50), and those with digestive conditions or taking certain medications (including metformin and proton pump inhibitors) are also at higher risk.

Why methylcobalamin is the best form of B12

Most cheap B12 supplements use cyanocobalamin — a synthetic form that the body must convert into its active forms before it can be used. Methylcobalamin is one of the two biologically active, co-enzyme forms of B12 that the body can utilise directly — no conversion needed. It’s the form of B12 that is naturally found in human blood and tissues, and it has been shown in clinical studies to be particularly effective for supporting neurological health and correcting B12 deficiency. The chewable tablet format also supports absorption through the mucous membranes of the mouth — bypassing the digestive system, which is especially beneficial for those with impaired B12 absorption.

Who is this for?

• People with digestive conditions affecting nutrient absorption
• Those taking metformin or proton pump inhibitors (which deplete B12)
• Anyone wanting to support nervous system health and mood
