Shop Vitamin B12 Supplements at Holland & Barrett

Vitamin B12 is a vital member of the B vitamin family and is vital for many functions in your body. This essential nutrient helps convert food into energy, supports a healthy nervous system, regulates your mood, supports your brain and contributes to normal red blood cell formation.

Unlike many other nutrients, our bodies cannot effectively produce or store vitamin B12. This makes it essential to obtain this nutrient through our diet or vitamin B12 supplements.

At Holland & Barrett, we want you to always feel your best. That’s why we stock an array of vitamin B12 supplements including vitamin B12 chewable tablets, sprays, capsules, liquids and more. You’ll even find tailored vitamin B12 for men and women.

  • Vitamin B12 tablets: traditional and effective, vitamin B12 tablets are perfect for those who prefer an easy, convenient and classic method to take vitamin B12.

  • Vitamin B12 sprays: fast-acting and convenient, these sprays are ideal for using on-the-go.

  • Vitamin B12 chewable tablets: also known as vitamin B12 gummies, these supplements are delicious and enjoyable, offering a fun way to support your health.

It is important to check with your doctor or GP that vitamin B12 supplements are right for you to take. They’ll be able to offer you advice and guidance.

Discover the B12 supplement that suits you best here at Holland & Barrett.
