Sneaky Signs Of Vitamin D Deficiency


Vitamin D is crucial to the human body because it helps regulate calcium levels in our blood. With low levels of vitamin D, cells are less able to absorb calcium, leading to bone thinning and deterioration. According to research, many symptoms could indicate a vitamin D deficiency.

If you experience any of these symptoms for more than two weeks, then it may be time for your doctor to test your vitamin D levels. This article will cover some of the most common signs of suffering from this deficiency.

Fatigue/Feeling Tired Often

You may feel utterly worn out, even if you get a lot of rest if you aren’t getting enough vitamin D. 

According to a study published in the North American Journal of Medical Sciences, people who felt tired had low vitamin D levels, but increasing vitamin D to normal levels significantly reduced feelings of tiredness. If you have been feeling exhausted for no reason, it could signify that you are vitamin D deficient.

Poor Immunity/Frequent Infections

Your immune system will be compromised if you aren’t getting enough vitamin D because the nutrient plays a vital role in fighting off infections and combating free radicals produced by an under-active immune system. The Journal of American College of Nutrition published research showing how people with low vitamin D levels were more likely to catch respiratory tract infections or skin problems such as herpes, eczema, or acne.

 If you frequently pick up minor illnesses like coughs and sniffles, this could indicate that your body needs more vitamin D than it’s currently receiving.

Dry Skin/Itching Or Rashes On Skin

Vitamin D helps produce oil glands which result in smooth and soft skin because it keeps your pores clear from blockages that can lead to dryness. If you don’t have enough vitamin D, this will result in dry, flaky patches developing all over your face and other places like knees, elbows, and back.

Moreover, if you experience itching or rashes after taking a shower, it could be another sign that you need more Vitamin D since these symptoms develop when there is too much yeast on the skin’s surface.

Bone Pain/Weakness

One of the most common and apparent signs that you may be deficient in vitamin D is bone pain. You might experience this as a general ache all over your body, or it might be focused on specific areas like your spine, hips, or ribs. If left untreated, low levels of vitamin D can cause bones to become thin and weak, leading to fractures. So if you’ve been feeling especially fragile lately or have been dealing with unexplained bone pain, get your vitamin D levels checked by a doctor.


A lack of sunlight can trigger depression symptoms due to a drop in serotonin levels. Researchers believe that a lack of vitamin D may also play a role in depressive episodes. One study published in Psychotherapy and Psychosomatics found that people with low vitamin D levels in their blood were more likely to experience depressive symptoms. So if you’ve been feeling down or lacking in motivation, then this could be a sign you need more vitamin D in your diet.

Trouble Sleeping

If you’ve been having trouble sleeping or waking up several times during the night, then it could indicate that your vitamin D levels are low. When your body releases serotonin at night, it produces a calming effect that makes us feel tired and ready for bed. 

Without enough Vitamin D in our bodies, we can’t produce as much serotonin, so we have difficulty relaxing and eventually become restless when trying to sleep. A study published by Current Psychiatry found that people who slept fewer hours were more likely to suffer from depression symptoms which led researchers to believe lack of sufficient sunlight exposure was a contributing factor behind these issues.

Sensitive Eyes/Light Sensitivity

One symptom of vitamin D deficiency is eye sensitivity because it affects how well the eyes process light without enough of this nutrient in the body. If you frequently experience discomfort when exposed to bright light or have blurry vision, then it could be a sign that your eyes need more vitamin D than they’re getting right now.

Cognitive Decline/Memory Loss

Another symptom of low levels of Vitamin D is impaired memory and cognitive function because it plays an important role in nerve signal transmissions throughout the brain. According to research published by Neurology, people who were deficient in vitamin D had reduced brain volume, resulting in less effective communication between nerves cells. Hence, memories are harder to recall, and focus becomes difficult.

So if you’ve been experiencing any trouble with short-term memory loss or forgetfulness lately, get tested for vitamin D deficiency as soon as possible before these symptoms worsen.


Vitamin D is essential for overall health, and without enough of it, our bodies can’t function at their best. So if you’ve been experiencing any of these symptoms, it’s important to get your vitamin D levels checked by a doctor to see if you’re deficient in this nutrient. Thankfully, getting more sunlight exposure or taking a vitamin D supplement are both easy ways to increase your levels and improve your well-being.
