What is Vitamin B12?

Vitamin B12 plays a vital role in many biological processes within the human body. It's important in the production of red blood cells and essential for cell replication. It also assists in helping our body convert food to energy.  B12 is also acknowledged for its benefits to the nervous system and the immune system.

Vitamin B12 is a water soluble vitamin meaning that the body cannot store it and it therefore needs to be consumed regularly.

Being deficient in vitamin B12 can cause tiredness and fatigue, muscle weakness, memory and mood problems.

Why take a Vitamin B12 supplement?

If you feel that you are not getting enough of this very important nutrient then a supplement provides a quick and easy way to boost levels.

Vegetarians and vegans may particularly benefit from supplementing with Vitamin B12 as the main food sources are meat, fish, dairy products and eggs.

Older people may also benefit more so by supplementing due to the fact that the body's ability to absorb Vitamin B12 declines as we age.

Vitamin B12, when combined with Folic Acid, may help maintain the heart, as together they are thought to help process levels of an amino acid called homocysteine.

Formulated for a direct route to the bloodstream

Just Vitamins Vitamin B12 complex tablet has been developed to allow sublingual administration (to be placed under the tongue and left to dissolve) if preferred. The tablet is blackcurrant flavoured, so tastes great too! You can of course, chew or swallow whole if you prefer, although sublingual administration is thought to offer the best and a more direct, and undisturbed route to the blood-stream.
