    Are You Getting Enough Vitamin B12?

    If you've been feeling a little sluggish or low in energy recently, or can't seem to stay awake all day, it might be time to get your vitamin B12 levels checked.

    B12 deficiency is one of the most common nutritional deficiencies in the United Kingdom affecting 6% of people under 60 and 20% of people over 60.

    Your body needs vitamin B12, but it can often be hard to get enough - especially if you follow a vegan or vegetarian diet.

    Long-term deficiency left untreated can lead to anaemia & nerve problems. Taking a high quality supplement can help if you think you may be deficient.

    Puro Vitamin B12 vs The Competition

    If you're going to get B12, get the good stuff. 

    Most vitamin B12 supplements use cyanocobalamin: a synthetic form of vitamin B12 that’s cheaper to manufacture, but poorly absorbed by the body.

    Frequently Asked Questions

    Yes many customers with anaemia respond well to this product.

    However, you should consult with your GP first to discuss your particular circumstances and to understand what dose may be the most suitable for you.

    This will vary from person to person as we're all unique and different!

    Some customers report feeling benefit in just a couple of weeks, while others may take up to 90 days.

    Taking supplements should always be considered a long-term endeavour for the best possible results, and we suggest taking this product for a minimum of 60 days.

    No Puro Vitamin B12 is formulated with superior Methylcobalamin which is easier for your body to absorb and more effective.

    Yes. Vitamin B12 is shown to help support energy levels and to contribute to reduced tiredness & fatigue.

    Certain groups of people such as vegans or vegetarians, older adults, a family history of anaemia, or people with certain long-term health issues, typically have higher vitamin B12 requirements.

    However it is also a common nutritional deficiency amongst the general UK population and so many people choose to take a supplement to help ensure they're getting enough.

    Vitamin B12 is involved in the function and development of the brain, nerve cells, the myelin sheaths that protect nerves, and blood cells. Vitamin B12 is sometimes taken to treat memory loss, poor concentration and to boost your mood or energy levels.
