Feeling tired all of the time could be caused by not getting enough sleep, or by spending too much time at work. Tiredness that goes on for long periods of time isn’t normal, and may be caused by an underlying medical condition. But, taking some supplements may help you to feel more energetic, and less lethargic. You could lower your chances of feeling tired, and improve your day-to-day energy by taking vitamin B12 supplements, it’s been claimed.
Feeling fatigued more than usual could be a sign of a vitamin B12 deficiency, warned Harvard Medical School.
Vitamin B12 is needed to make red blood cells, DNA and nerves. But it can’t be made naturally in the body, and is needed from your diet.
You could top up on vitamin B12 by eating more clams, liver, beef, Greek yogurt, or even eggs.
“Vitamin B12 deficiency can be slow to develop, causing symptoms to appear gradually and intensify over time,” said the medical school.
“Given the array of symptoms a vitamin B12 deficiency can cause, the condition can be overlooked or confused with something else.
“Vitamin B12 deficiency symptoms may include weakness, fatigue, strange sensations, numbness, or tingling in the hands, legs, or feet.
“A standard multivitamin delivers 6 micrograms, more than enough to cover the average body’s daily need.
“If you are over age 50, the Institute of Medicine recommends that you get extra B12 from a supplement, since you may not be able to absorb enough of the vitamin through foods.”
You could also be at risk of a vitamin B12 deficiency if you develop a swollen, or inflamed tongue, or difficulty walking.
Most people should be able to get enough vitamin B12 from their daily diet, said the NHS.
But, if you do decide to take vitamin B12 supplements, you should avoid taking more than 2mg a day, as it could be harmful.
Other than a vitamin B12 deficiency, your persistent tiredness could be caused by stress or anxiety.
Anaemia, an underactive thyroid and sleep apnoea could also lead to feeling tired all of the time.
If you’ve been feeling tired for more than four weeks, it’s a good idea to speak to a doctor, said the NHS.
Making sure you get enough sleep could help to prevent you from feeling sleepy the next day.
Most adults need between six and nine hours of sleep every night to perform at their best the next day.
