Pure Encapsulations B12 (Methylcobalamin) is a food supplement providing 1000 mcg of vitamin B12 in its methylcobalamin form, in a pack of 60 vegetarian capsules taken once daily.

Key Features

• High-strength, single-nutrient formula: each capsule provides 1000 mcg of vitamin B12 (as methylcobalamin), equivalent to 40,000% of the Nutrient Reference Value, as a dedicated B12 supplement rather than part of a multivitamin blend.
• Minimal ingredient list: contains only one other ingredient, hypoallergenic microcrystalline cellulose, plus a plant-based (hydroxypropyl methylcellulose) capsule shell, with no magnesium stearate, artificial colours or flavours.
• Suitable for vegans and vegetarians: the capsule shell is plant-derived rather than gelatine, and the formula contains no animal-derived ingredients.
• Free from major allergens: manufactured without gluten, egg, dairy, peanuts, soya, fish, crustaceans, molluscs or celery.
• One capsule a day: a simple once-daily dose taken with a meal, rather than multiple doses through the day.

Who might need to take a vitamin B12 supplement?

Vegans and vegetarians are more likely to have a lower vitamin B12 intake, since the vitamin is found almost exclusively in animal-derived foods. People with reduced stomach acid, certain digestive conditions, or those taking long-term medicines such as metformin or acid-reducing treatment may also be more likely to have lower B12 levels. A healthcare professional can advise on whether a supplement is appropriate for you.

Why does this product use methylcobalamin rather than another form of B12?

This supplement provides vitamin B12 in its methylcobalamin form. Methylcobalamin is one of the forms of vitamin B12 that occurs naturally in the body, alongside other forms such as cyanocobalamin used in some other supplements.

Why is the %NRV for this supplement so high?

Each capsule provides 1000 mcg of vitamin B12, equivalent to 40,000% of the Nutrient Reference Value (NRV). This reflects a deliberately high-potency, single-nutrient dose rather than a standard maintenance amount found in many multivitamins. Do not exceed the stated dose unless advised by a healthcare professional.
