What Is Vitamin B12 and Why Do You Need It?

Vitamin B12, also known as cobalamin, is a water-soluble vitamin that is essential for several bodily processes. It helps convert food into glucose, which your cells use for energy. B12 is also necessary for maintaining healthy nerve cells, supporting red blood cell formation, and aiding in DNA synthesis. Since the body cannot produce B12, it must be obtained from diet or supplements. The reference nutrient intake (RNI) for adults in the UK is approximately 1.5 mcg per day, but many people choose higher doses to ensure adequate levels.

Who Should Take a Vitamin B12 Supplement?

Certain groups have a higher risk of B12 deficiency and may benefit from supplementation. Vegans and vegetarians often lack dietary B12 because it is naturally found only in animal products. Older adults may have reduced stomach acid, which impairs B12 absorption from food. Individuals with digestive conditions such as Crohn's disease or pernicious anaemia, or those who have had weight loss surgery, may also struggle to absorb enough B12. Additionally, people taking certain medicines, such as metformin or proton pump inhibitors, can have lower B12 levels. If you belong to one of these groups, a B12 supplement can help maintain optimal levels.

Recommended Dosage and How to Take B12

Take one tablet daily. Place it on your tongue and allow it to dissolve completely – typically about 30 seconds – before swallowing. No water is necessary, making it convenient for use at home or on the go. The 2,500 mcg dose is suitable for most adults, but consult your health care professional for personalised advice, especially if you have a diagnosed deficiency or medical condition.

How to Choose the Best B12 Supplement

When selecting a B12 supplement, consider the form and dosage. This product use cyanocobalamin, a stable and well-absorbed form of B12. While methylcobalamin is the bioactive form, cyanocobalamin is equally effective for most people and has a longer shelf life. The 2,500 mcg dose per tablet is higher than the RNI, but because B12 is water-soluble, excess is excreted, and high doses are generally safe and can help overcome absorption issues in certain individuals.

Delivery method also matters. Quick-dissolve tablets dissolve in the mouth, allowing B12 to be absorbed directly through the oral mucosa, bypassing the digestive system – ideal for those with absorption concerns. This product also has a pleasant cherry flavour without artificial colours or flavours.
