Vitamin B12 is very important for the production of red blood cells in the body. If a person is deficient in vitamin B12, red blood cells can become abnormally large and can’t function properly. B12 is best gained through diet, with adults requiring 1.5mg a day. Here are six vitamin B12-rich foods you should consider eating to avoid the development of vitamin B12 deficiency – it’s full name, vitamin B12 deficiency anaemia.
What are the symptoms of vitamin b12 deficiency anaemia?
Some of the most notable symptoms of vitamin B12 deficiency anaemia are feeling very tired, breathlessness even after little exercise, a sore mouth and tongue and heart palpitations.
Having a vitamin B12 deficiency can play havoc on your digestive tract, according to the National Heart, Lung, and Blood Institute, and this can cause diarrhoea.
Diarrhoea is identified as faeces being discharged from the bowels frequently and in a liquid form.
But it should also be noted that diarrhoea and constipation can be caused by a viral or bacterial infection, a food intolerance or a change in diet.
The best way to find out the cause is to see your GP.
How is vitamin B12 deficiency treated?
In many cases, particularly in more serious cases, vitamin B12 is treated with injections or tables to replace the missing vitamins.
The NHS explains: “Vitamin B12 supplements are usually given by injection at first. Then, depending on whether your B12 deficiency is related to your diet, you’ll either require B12 tablets between meals or regular injections.
“These treatments may be needed for the rest of your life.”
The Department of Health advises if you take vitamin b12 supplements, don’t take too much as this could be harmful.
Taking 2mg or less a day of vitamin b12 supplements is unlikely to cause any harm.
