Why is vitamin B12 important?

Whilst all vitamins and nutrients are important, Vitamin B12 has a vital role for our bodies.

Vitamin B12 works with our body to support growth, development as well as cognitive brain function and the nervous system. Not only does it do all of this, but it also supports red blood cell formation, which then helps the body to carry oxygen to its tissues and organs.

Vitamin B12 is also an essential vitamin that our body can’t produce on its own. We need to get it from our diets or from Vitamin B12 tablets or B12 supplements.

What are the health benefits of vitamin B12?

Making sure our Vitamin B12 levels are maintained comes with huge health benefits, including:

  • Improved bone health.
  • Healthy red blood cell formation.
  • Improved oxygen to the blood and tissues.
  • Boosted energy levels and reduction in fatigue.
  • Improved brain function and focus.
  • Calmer nervous system and improved mood.

What are the symptoms of low Vitamin B12?

If your body is lacking this vitamin and has a Vitamin B12 deficiency, which can sometimes be known as folate deficiency anaemia, it will show some obvious signs.

If your body begins to show any of these symptoms, then it could be possible that you’re running low on Vitamin B12:

  • Extreme tiredness and fatigue.
  • Lack of energy and feeling lethargic.
  • Breathlessness, even when sitting still.
  • Pale skin.
  • Heart palpitations.
  • Ringing sounds such as tinnitus.
  • Sore and red tongue.
  • Mouth ulcers.
  • Disturbed vision.
  • Muscle weakness.
  • Pins and needles (paraesthesia)
  • Feeling faint or lightheaded.
  • Headaches, especially those that reoccur.

To diagnose a Vitamin B12 deficiency, your doctor may run blood tests to see whether you have low haemoglobin or Vitamin B12 levels. These tests may include a complete blood count, which measures haemoglobin as well as a test to measure Vitamin B12 levels in the blood.

What causes Vitamin B12 deficiency?

There are a few health conditions and factors that can lead to a Vitamin B12 or folate deficiency. Some of the most common include:

Pernicious anaemia
This is when your immune system attacks healthy cells in your stomach and reduces the amount of Vitamin B12 your body can absorb from food. This is one of the most common causes of Vitamin B12 deficiency in the UK.

Lack of these vitamins in your diet
Not eating enough vitamins in your diet can cause many health problems, including a Vitamin B12 deficiency. A vegan diet can sometimes result in lower vitamin intake due to not eating certain foods and over time this can cause health issues, which can be improved with supplements.

Certain medications can have an impact on how much our body absorbs vitamins.

How can I improve my Vitamin B12 intake?

If you have low vitamin B12 then you may need to look at your diet and eat more animal products, like meat, seafood, dairy and eggs. Yet when you’re vegan or vegetarian this isn’t possible, and whilst there are vitamin B12 rich products like fortified breakfast cereals, you may need to consider vitamin B12 supplements.

A daily vitamin B12 tablet can be beneficial to boost your levels and reduce symptoms like fatigue, low mood, headaches and feeling faint or lightheaded.

How much Vitamin B12 should I have?

The recommended daily intake (RDI) for Vitamin B12 for people over 14 is 2.4 micrograms. However, you may want to take more or less, depending on your age, lifestyle or health needs.

Vitamin B12 deficiency and folate deficiency are a lot more common in older people. Current data suggests that this affects around 1 in 10 people aged 75 or over, and 1 in 20 people aged 65 to 74 in the UK.

Vegans can be at risk of vitamin b12 deficiency due to not being able to get it from their diet as they don’t consume animal products. As a result, this can mean they need to have a Vitamin B12 supplement such as a Vitamin B12 tablet or even have Vitamin B12 injections to help boost their levels.


What supplements can help with Vitamin B12 deficiency?

If you are lacking in Vitamin B12 then there are plenty of options to help improve your intake, and help improve mood, energy and health.

Once diagnosed with low Vitamin B12 levels, you’ll usually take cyanocobalamin tablets every day to prevent or treat Vitamin B12 deficiency.

It may take a few weeks before your Vitamin B12 levels and symptoms, such as extreme tiredness or lack of energy, start to improve.

Are there side effects from taking Vitamin B12 supplements?

There are side effects from taking Vitamin B12 supplements, like any supplement or tablet.

Side effects from too much Vitamin B12 can include:

  • Nausea
  • Headaches.
  • Dizziness and light headedness.
  • In very rare cases, blood clots and cancer.

How quickly does Vitamin B12 work?

Taking a Vitamin B12 supplement can get to work quickly and improve mood and energy levels within a few days. It can also quickly help to improve red blood cell formation, DNA and to improve brain function and focus. Not just to be taken as a brain supplements, but it has huge benefits in the body that can be seen and felt quickly.

As a long term solution to Vitamin B12 deficiency it may take a few weeks for the levels to improve. This can mean that some of those symptoms including extreme tiredness and exhaustion take longer to go away.

Can Vitamin B12 help with energy?

Vitamin B12 can help to improve energy level as it helps the body to turn food including carbohydrates into energy.

Can vegans take Vitamin B12?

Vegans and vegetarians can benefit from a vegan Vitamin B12 supplement or Vitamin B12 tablets

Vitamin B12 deficiency can affect anyone. If your diet includes meat, fish, or dairy, you more likely obtain sufficient Vitamin B12 from those sources. However, since Vitamin B12 is absent in natural form in fruits, vegetables, and grains, individuals following a vegan diet may face challenges in obtaining an adequate amount.

The benefits of Vitamin B12:

Metabolic support

Restores the body’s minerals and vitamins and helping it with essential nutrients that support the body’s metabolism,

Nervous system regulation

Strengthens the functions of the nervous system and helps to calm the mood and reduce stress levels.

Brain function

Improves psychological function and focus as well as boosting focus, clarity and concentration.

Vitamin B12 created through fermentation

Like many vitamins, Vitamin B12 is usually sourced from animals - but not ours. We use Vitamin B12 produced by fermentation, which means you get the same benefits, just in a cruelty-free tablet and it’s perfect for a vegan diet and lifestyle.

Each tablet provides a high strength dose of 1000µg Vitamin B12 designed to release Vitamin B12 in a sustained way over six to eight hours. This is ideal for individuals with Vitamin B12 deficiency, in need of a boosted dose.

Vitamin B12 is water-soluble, which means the body takes what it needs, and the rest passes harmlessly through the body. One of the problems is the body doesn’t always take enough, or indeed have the time to take enough.

That’s why we designed a sustained release tablet, to ensure a steady and sustained delivery of B12 as the tablet breaks down in the stomach over a six to eight hour period. This gives the body more chance to take what it needs, and the higher dose helps individuals who even have acute deficiency. Again, any surplus passes through harmlessly.

Your body thrives when it has the right balance of nutrients for optimal health and energy. This Vitamin b12 supplement will help to improve your energy levels and to feel more focused and perform better.

I require vitamin B12 injections every 3 months, I am vegan but my brother also has the same problem and he is not vegan but has a healthy diet . The Dr says it must be a family issue. I have been told it is a waste of time taking any B12 supplements as my body won’t store it, does that sound correct ? I also have osteoporosis, arthritis and my mother has vascular dementia. I am looking for help as to which vitamins and supplements you may recommend to help me address some of these issues without doubling up or missing out on anything vital. I know it sounds like a bit of a train wreck but I need to act now to stop it getting worse. I am vegan, active ( not what you would call fit though . Many thanks. Glenda. Hi, Vitamin B12 deficiency is a widespread issue and it is correct the body isn't very good at storing it, as it is a water-based vitamin. Our sustained release tablet is worth trying being it is very high dose and designed to breakdown slowly over 4-6 hours. That way the body has access to a lot of B12 over a prolonged period of time and will grab what it needs. For your other question, our Bone Care formula is well worth trying. We get excellent feedback about it and the formula is really well balanced to support Bones, Joints, and muscles. We hope this helps.
I have read that tablets have more filler and so it's better to go with capsules. Could you explain the reasoning behind them being tablets please? Hi, Capsules are good for some formulas but in the case of Bone Care we can't squeeze everything into a capsule as it would be too big. We also have a break-bar on the tablet to make it easier to take for people who prefer to snap it in half, and that wouldn't be possible for a capsule in this case either. For our Sustained Release VitB12 formula, the tablet itself is critical to obtaining the desired rate of breakdown and absorption. To be honest the talk of 'fillers' in tablets is nonsense. Excipients are needed to hold the tablets together (instead of having a pile of powder) but these are always at the lowest possible level in our tablet formulas, and to the best of our knowledge the same for other brands too.
I was recently sent a clip of a guy saying Cyanocobalamin comes from raw sewage. I googled it and it confirmed sewage sludge. I'm concerned about taking B12 now because of this. Where is yours derived from? Thanks Hi, well that's a new one! Our B12 is produced using fermentation (plant substrate) and is of the highest purity. We are delighted to say it has absolutely nothing to do with sewage sludge. From a little research, it appears some very low grade B12 can be produced from waste water for use in animal feed.
Can you confirm that your B vitamins are naturally derived and fermented from food sources - as opposed to the pharmaceutical ones from the chemist? Hi, our B Vitamins are produced using fermentation (plant-source substrates).
Hi from Canada I recently ordered and received your B12. After listening to a few podcasts I looked to see what type of B12 is used and it turns out that it is Cyanocobalam. This was concerning to me as it was identified as being a NOT good form of B12. Is this the only B12 suitable for Vegans Thank you in advance Nicole Hi, Cyanocobalamin is an excellent form of B12. It has very good stability and also bioavailability. In our Sustained Release formula, this is the ideal form of B12. In our Sublingual tablet, we combine 3 different types of B12. All are suitable for vegans.
Can you recommend which dose and b12 would be best for 18 month olds and how to give it to them? I’m assuming my daughter won’t be able to keep the tablet under her tongue. Are there any other ways? Hi, we don't recommend our B12 formulas for young children unless specifically recommended by your Doctor or Health Practitioner. Both of our formulas (the 1000mcg Sustained Release formula and 100mcg Sublingual tablet formula) are high strength and designed for adults. We don't offer a lower dose singular B12 formula at this time.

    Both my energy levels and mood have increased, no more nervous energy, calmed me down getting what I need. Concentration better too with immediate effect and have continued to use ever since! Can't recommend enough. Best to ensure you are receiving enough B12 than not, as your system flushes out any excess anyway. Small, taste free, but smell kind of fruity, subtly so. Can't rate them enough frankly.

    Do not buy the B12 vitamin. I had a subscription and canceled it after I found out that it contains CYANOCOBALAMIN. Essentially, cyanide. They are not transparent about what is in the B12 as it is a combination. Find a supplement that only contains METHYLCOBALAMIN.

    The general view in the Nutrition industry is that Cyanocobalamin is the superior variant of B12 versus Methylcobalamin. We sought a lot of advice, including from the Vegan Society's scientific experts. The Cyanocobalamin we use is produced through a fermentation method. It is more stable than Methylcobalamin, and doesn't have some of the reported negative skin effects reported. The cyanide point needs perspective of levels. Many fruits and vegetables contain cyanide, which sounds horrific, but the levels are tiny and that is where we are. Our bodies are always ingesting small amounts of cyanide through our diets. If we (or food and nutritional regulators) had any concerns whatsoever, we wouldn't use it.

    Usually, supplements do not trigger direct effects that you can feel. However they contribute to the good equilibrium of your body. Some effects can be eventually seen during regulare blood analysis.

    B12 is a great supplement for me since I don't eat a lot of meat. It does not have any side affects. The pill is easy to swallow and digest. I love being able to get products that are plant based and all natural. I have been on this for over 6 years and wouldn't use anything else.
