Like additional B vitamins, vitamin B12is important for metabolism. that will also helps inside the formation of red blood cells as well as in maintaining the central nervous system. that will is usually found in most foods which come by animal products including liver, fish, shell fish, meat as well as dairy products.
Side Effects
The not bad news is usually that will vitamin B 12 is usually usually non-toxic, even when taken in large doses. However, people have experienced some adverse effects, even though these side effects are quite rare. Generally, when vitamin B12 supplements are taken orally then there is usually little chance of side effects occurring. Some people choose to take vitamin B12 administered with an injection. This kind of type of ingestion as been associated with the following side effects:
o mild diarrhoea
o anxiety as well as panic attacks
o heart palpitations
o insomnia
o breathing problems
o chest pain
o skin rash, hives or itchy swollen skin
Some health professionals believe that will patients develop these reactions not because of the B12, however because of the preservatives that will are part of the injection formula. Currently, most injections contain preservatives. To be on the safe side, that will is usually probably better to take B12 orally.
Medical Conditions
additional side effects may be experienced by people who have an allergy or a sensitive to cobalamin as well as cobalt. If This kind of is usually the case, then that will is usually advisable to avoid vitamin B12 supplementation altogether as well as instead seek to eat the foods that will contain naturally occurring B12. In addition B12 should be avoided by people suffering by Leber's disease, a hereditary disease in which the optic nerve wastes away.

There is usually also evidence to suggest that will patients who have undergone heart surgery as well as received coronary stents may have an increased risk of the artery narrowing again when they take vitamin B12. A little risk, however one to bear in mind.
On a positive note, pregnant as well as breastfeeding women can take vitamin B12 quite confidently when that will is usually taken orally in amounts not exceeding the recommended daily allowance (2.6 mcg/day if pregnant as well as 2.8 mcg/day if breastfeeding)
As can be seen, vitamin B12 is usually a relatively safe vitamin with very few adverse side effects even when taken in large doses. More problems than not arise by B12 deficiency than they do by ingestion of the vitamin itself.
