According to a study by US National Library of Medicine National Institutes of Health, vitamin B12 deficiency may affect a person’s sleep-wake rhythm.
The study involved two patients who have been suffering for many years from different sleep-wake rhythm disorders.
The patients were both administered vitamin B12 and were monitored over a period of time. The study concluded that vitamin B12 improved their sleep-wake rhythm disorder.
Other symptoms of you may be vitamin B12 deficient
When a person has a vitamin B12 deficiency they may become anaemic.
A mild deficiency may cause no symptoms but if left untreated it may lead to symptoms such as weakness, tiredness, pale skin, a smooth tongue, constipation or diarrhoea.
They may also experience mental problems such as depression, memory loss or behavioural changes.
Since your body doesn’t make vitamin B12, you have to get it from animal-based foods or from supplements.
And you should do that on a regular basis, because your body doesn’t store vitamin B12 for a long time. How much vitamin B12 a person should get depends on things including age, eating habits and medical conditions.
The average amount for adults is 2.4 mcg per day and should not be exceeded unless your GP suggests so.
