Affecting one in five Britons, vitamin D deficiency can become more prevalent during the winter months. Becoming deficient in the sunshine vitamin can pose a higher risk of illness and infections. Here are the warning signs which could help spot the lack of this nutrient.
According to the North American Journal of Medicine & Science, low levels of the sunshine vitamin can manifest as tiredness in otherwise healthy individuals.
Tiredness, or fatigue, can make you feel unable to maintain or sustain your force.
But the journal shares that patients often describe low levels of energy as tiredness as well.
Healthline reports that this particular sign is “often overlooked”.
DON’T MISS
The journal SpringerPlus says that particularly lower levels of vitamin D can cause tiredness, posing negatively on your quality of life.
A study published in the Global Journal of Health Science looked at the lack of the sunshine vitamin in nurses.
They noticed a significant link between low levels of the vitamin and self-reported tiredness.
What’s more, other studies found that supplementing with vitamin D could lower the extent of this symptom.
How much vitamin D do I need?
Everyone over the age of one year needs 10 micrograms of vitamin D daily.
Vitamin D content can be also expressed in international units (IU), which brings your daily target to 400 IU.
The sources of this vitamin include sunlight, certain foods, such as oily fish and mushrooms, or supplements.
The Government recommends looking into supplementing this vitamin between October and early March as your body might not be able to synthesise it organically due to the lack of sunlight, the NHS states.
