Vitamin B12 deficiency is the most common nutritional deficiency in vegans and vegetarians, and is increasingly common in older adults and people on metformin or acid-suppressing medication.
Our sublingual (dissolve-under-tongue) tablets bypass the stomach's absorption pathway — bypassing the need for intrinsic factor. This makes them effective even in people with absorption problems.

✨What customers say
From 20 reviews★ 4.5Customers appreciate the high dosage of 1,000mcg of methylcobalamin, which effectively addresses B12 deficiencies and enhances energy levels, especially for those switching from cyanocobalamin. The sublingual form is praised for its excellent absorption.
Some users noted that the taste can be unpleasant, and a few experienced minor digestive discomfort when not allowing the tablet to dissolve fully under the tongue.
This product is ideal for vegans and vegetarians who require B12 supplementation, as well as individuals with absorption issues like pernicious anaemia, seeking a convenient and effective alternative to injections.

Plant-based diet requires B12 supplementation without exception. Methylcobalamin is the active form that doesn't require liver conversion. Nerve function, energy, and cognitive clarity all excellent after 18 months on this.

- ★★★★☆Rachel T.Verified buyer31/10/2025Energy and nerve health
Fatigue and mild neuropathy linked to suboptimal B12. 3 months on methylcobalamin 1000mcg and energy is measurably improved. The methylcobalamin form is directly usable by the nervous system.
- ★★★★★Ellen M.Verified buyer29/10/2025B12 levels finally optimal
Serum B12 was bottom of range for years on cyanocobalamin supplements. Switched to methylcobalamin 1000mcg. Blood test 3 months later: B12 well into optimal range. Fatigue improved, memory sharper, pins and needles in feet gone.
- ★★★★★Ian C.16/09/2025Better than injections for me
Started B12 injections for deficiency but they're inconvenient. Switched to 1000mcg methylcobalamin sublingual with GP approval. Blood tests confirm equivalent absorption. More convenient and effective.
- ★★★★☆Patricia N.Verified buyer19/08/2025Pernicious anaemia management
PA means I can't absorb B12 from food. High-dose sublingual methylcobalamin bypasses intrinsic factor dependence via buccal absorption. GP confirmed this approach is effective. B12 levels now consistently optimal.
