Simon Cowell, Katy Perry and Madonna all apparently have injections of B12, the nutrient which helps keep the body’s nerve and blood cells healthy and helps make DNA, the genetic material in all cells. Vitamin B12 also helps prevent a type of anaemia called megaloblastic anaemia that makes people tired and weak.
The total amount of vitamin B12 stored in body is about 5mg in adults with around 50 per cent of this being stored in the liver – for several years if needed.
This sounds positive – and it’s fair to say that nutritional deficiency of this vitamin should be rare. But as approximately 0.5 per cent of this is lost per day by secretions into the gut, and not all these secretions are reabsorbed, deficiency is becoming more predominant than ever.
How fast B12 levels change in the body depends on the balance between how much is obtained from the diet and the amount lost.
However the vitamin is very poorly absorbed and the rate of absorption is decreasing rapidly as our modern Western diet moves from one of fresh meats and seasonal vegetables to more processed foods, resulting in our digestive efficiency reducing.
A healthy digestive system will absorb only one per cent of the B12 from our diet. However our ability to produce the acids necessary for absorption is reducing dramatically and deficiency is now being reported more and more, even amongst the most seemingly healthy. Worryingly deficiency in infants appears to be becoming even more prevalent than amongst adults.
The result is that more and more of us now require B12 supplementation.
The tissue lining of the mouth offers a strong alternative for effective absorption of our nutrients. Vitamin sprays like the BetterYou B12 Boost supplement spray is a good option.
Research carried out by Cardiff University investigating sublingual vitamin absorption found that nutrients are absorbed faster through the sub-lingual membrane – below the tongue and soft palate, and the buccal membrane – the inner lip and cheek area, than any other tissue area, other than the lungs.
Absorption rates were found to vary depending upon the type of the nutrient. B12 offers potentially better absorption rates than other nutrients, as this vitamin is water soluble, entering the membrane tissue more readily.
