Key Benefits

Start your day with confidence—Methylcobalamin is the active, ready-to-use form of Vitamin B12. Unlike some B12 supplements that need to be converted by your body, this form is available straight away to support your daily routine.

Vitamin B12 is essential for releasing energy from your food, supporting your nervous and immune systems, and helping to form healthy red blood cells. It also plays a role in normal psychological function and homocysteine metabolism, so you can feel your best every day.

Many B12 supplements use cyanocobalamin, which your body must convert before it can be used. Thorne’s Vitamin B12 uses Methylcobalamin, a form your body can absorb and use efficiently.

Choose Thorne’s Vitamin B12 for a simple way to support your energy and wellbeing—every capsule delivers this vital nutrient in a form your body loves.
