Vitamin B12 Supplement | Methylcobalamin & Adenosylcobalamin | Pure Vitamins UK

Most B12 supplements on the UK market are doing the bare minimum. Vitabiotics' Neurovital and Holland & Barrett's standard B12 tablets both lean on cyanocobalamin a synthetic, inactive form that your body still has to convert before it can use it. That conversion isn't guaranteed, and it's certainly not optimal. Pure Vitamins doesn't cut that corner. B12 Dual Power delivers both biologically active coenzyme forms Methylcobalamin and Adenosylcobalamin at a meaningful 1000 µg daily dose, with nothing hidden behind a proprietary blend and nothing padded out with unnecessary fillers. Two active forms. One clean formula. Built for people who actually read the label.

✔ Methylcobalamin - Nervous System & Brain Function

Methylcobalamin is the neurologically active form of B12, directly involved in nerve cell maintenance and methyl-group donation processes your body can use immediately, no conversion required. It contributes to the normal functioning of the nervous system, normal psychological function, and normal cognitive function. Cheaper supplements default to cyanocobalamin precisely because it costs less not because it's better.

✔ Adenosylcobalamin - Cellular Energy Metabolism

Adenosylcobalamin is the mitochondrial coenzyme form of B12, working inside your cells where energy is actually produced. It contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue at the cellular level not through stimulants, but through supporting your body's own metabolic machinery. You won't find this form in most high-street tablets. That's the gap B12 Dual Power fills.

✔ 2:1 Dual-Form Ratio - Precision Over Padding

The 2:1 Methylcobalamin-to-Adenosylcobalamin ratio isn't arbitrary. It reflects the distinct physiological roles of each form — neurological support and mitochondrial energy function — delivered together in a single daily serving. Single-form B12 products cover one pathway. This covers both.

✔ 7-Action Support - Not Found in Standard UK B12 Tablets

Together, the active ingredients in this formula contribute to:

• Normal energy-yielding metabolism
• The reduction of tiredness and fatigue
• Normal functioning of the nervous system
• Normal psychological function
• Normal cognitive function
• Normal formation of red blood cells
• Normal homocysteine metabolism

Most UK B12 supplements are formulated around cost, not coverage. Delivering both active coenzyme forms at this dose, in a clean format, takes more. Most brands simply don't bother.

✔ No Cyanocobalamin. No Fillers. No Shortcuts.

B12 Dual Power contains no cyanocobalamin, no artificial colours, no artificial flavours, no preservatives, no added sugars, and no unnecessary bulking agents beyond what's required for tablet integrity. No proprietary blends obscuring what you're actually getting. Every ingredient is there for a reason and if it isn't, it isn't there.

✔ Clean, Transparent, Premium-Crafted Supplement

• Manufactured in GMP-certified facilities and tested for purity and heavy metals
• 100% vegetarian tablets
• Non-GMO raw materials
• No artificial colours or preservatives
• Gluten-free

You chose the formula that doesn't take shortcuts. That's exactly the point.
