The science behind our energy-boosting Vit B12 supplement

Whether it’s to stay sharp at work, improve performance in sport or to feel energised and ready to keep up with a busy schedule; sometimes we need a helping hand.

One of the body’s core vitamins is delivered in our vegan B12 supplement that not only boosts your metabolism but leaves you energised and recharged. As one of the key vitamins for immune systems and keeping healthy, it works with many others to have us feeling at our best.

With a scientific formula that has been crafted to prolong performance and leave you feeling your best, these vitamin B12 tablets are designed to be part of a healthy lifestyle and are perfect for vegans and vegetarians.

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.

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.

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.

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.

FAQs
Our B Vitamins are produced using fermentation (plant-source substrates).
We use Cyanocobalamin in our Sustained release formula because it is the most stable form for this type of product. It has very good stability and also bioavailability. We always choose the best forms for the formula type and delivery systems.
No it doesn't contain any soy
Yes it does. The tablet structure is essential for the sustained release effect. It is pretty small and easy to swallow.
The body takes the B12 it requires and the rest is safety excreted. The reason we use a high dose in a sustained release tablet is to allow the body the best chance of getting the amount it requires. Once your B12 status normalises, this level of B12 could be taken weekly rather than daily to maintain the status.
