Shop Vitamin B12 Supplements at Holland & Barrett

FAQs

What is vitamin B12 deficiency?

Most of us can't get enough vitamin B12 through our daily diet, but sometimes we may need a little help. As we age, our bodies become less efficient at absorbing vitamin B12, increasing the risk of vitamin B12 deficiency

 

However, there are other reasons why you may lack vitamin B12. This includes:

 

  • Your diet: following a vegan diet or not having enough meat, poultry, fish, or dairy can lead to a deficiency.
  • Digestive issues: conditions like Crohn's disease or coeliac disease can interfere with B12 absorption.
  • Your age: as we get older, our bodies become less efficient at absorbing vitamin B12, increasing the risk of a vitamin B12 deficiency. 

  • Medications: certain medications can reduce B12 levels.

  • What foods contain vitamin B12?

    Vitamin B12 is primarily found in animal-based foods like meat, fish, poultry, eggs, and dairy. If you’re a vegan, B12 is also added to many breakfast cereals and plant-based milk alternatives. 

     

    Struggling to get enough vitamin B12? Our range of vitamin B12 supplements offers convenient and effective options, including tablets, capsules, liquids, and sprays.

    Is vitamin B12 and folic acid the same?

    No, vitamin B12 and folic acid are not the same. While they are both essential B vitamins and work together in some bodily functions, they have distinct roles and sources.

    Can I buy vitamin B12 over the counter?

    Yes, you can buy vitamin B12 supplements over the counter. You can shop B12 supplements here at Holland & Barrett in various forms, including tablets, capsules, liquids, sprays and more.

    What is the best vitamin B12 supplement for seniors?

    Some factors to consider when choosing a B12 supplement for seniors include the dosage as you’ll want to look for a higher dosage, as absorption can be less efficient with age, and the form - sprays can offer better absorption for some. 

     

    You’ll also want to look for additional nutrients, like supplements which contain vitamin D3 and B12, or other essential nutrients like folate or vitamin B6, which can benefit seniors.

     

    It's crucial to consult with a healthcare provider before starting any new supplement, especially for seniors. They can assess your individual needs and recommend the most appropriate B12 supplement for you.
