What is Vitamin B12?
Vitamin B12, also called cobalamin, is a crystalline compound that is bright red due to its high cobalt content. Its key roles are in red blood cell and nervous system health. It was first identified as the nutrient needed to treat pernicious anemia. This is a condition in which the gastric mucosa lacks a protein called intrinsic factor, needed to absorb vitamin B12 in the ileum. As vitamin B12 is needed for red blood cell formation, a deficiency due to malabsorption results in a form of anemia.
The most abundant and readily absorbed sources of Vitamin B12 are animal foods. Vegetarians and vegans may be more at risk of becoming vitamin B12 deficient, and as we age the body’s ability to absorb B-12 from food sources decreases as well.
Vitamin B12 Benefits
Signs of vitamin B12 deficiency are in symptoms of nervous system impairment such as numbness and tingling, pins and needles or a burning sensation. Deficiency is more common in elderly people and can show as anemia, diarrhoea and a beefy red tongue. Impaired mental function in the elderly may respond well to vitamin B12 supplementation.
People with asthma and eczema may need vitamin B12, and addressing a deficiency may also bring improvements in sleep quality, alertness and concentration.

Vitamin B12 (cobalamin) is best taken in conjunction with a B complex supplement, as all the B group vitamins need to be present in the correct ratio for optimal effect.
Vitamin B12 Reviews
"I've been taking these for about 18 months now. Having had gastric bypass surgery, the sublingual is essential because I can't absorb B12 through my gut. Bronson is easy to take, tastes pleasant and has kept my B12 levels in the healthy range so I don't need to have injections."
