What are the 14 signs of vitamin D deficiency?


If you’re living in London, the busy run-up to Christmas will no doubt have you feeling worn out. Short term, this is ok, but do you feel tired on a daily basis, for no apparent reason? Fatigue, weak bones and low mood are some of the key signs of a vitamin D deficiency. But why is vitamin D important in the first place and how can you determine if your body is lacking in vitamin D? Let’s find out.

Why is vitamin D important?

Vitamin D, also known as the sunshine vitamin, plays a vital role in performing various bodily functions. One of the most commonly known benefits of this vitamin is strengthening our bones. It does so by increasing calcium absorption.

But if you think that vitamin D is only about bone health, you’d be mistaken; this vitamin plays a vital role in our mood regulation as well. Studies have shown that this vitamin alters the production of serotonin in the brain, which results in improved mental wellbeing and lesser risk of depression and anxiety.

And if you thought the list of benefits ended there, well you are in for a surprise. Vitamin D also supports the cardiovascular system by improving blood vessel functioning thereby minimising the risk of heart disease. It also helps regulate blood pressure, which further minimises the risk of stroke or heart attacks.

Vitamin D is also known to manage the inflammatory response of the body, which can benefit us by keeping autoimmune diseases and various other health concerns at bay.

14 Signs that indicate vitamin D deficiency

The list of vitamin D benefits may be long, but the list of symptoms of a deficiency is even longer!

Most people who live in the northern hemisphere are deficient in vitamin D, and this is because of the lack of sunlight. Vitamin D is primarily produced via exposure of the skin to sunlight. Vitamin D is particularly important during the winter months when our skin is not exposed to daylight as often as in the summer.

But how do you know if you are vitamin D deficient? Here are some symptoms to look out for:

1. Fatigue

Fatigue is a symptom of many different conditions. However, if you feel tired and low on energy almost constantly, it may be wise to check if you have a vitamin D deficiency.

2. Frequent bone pain or aches

Feel like you’re too young to be experiencing bone pains and aches? Vitamin D is an essential vitamin for supporting the bones.

3. Muscle weakness or cramps

If you develop cramps easily after exercise or your muscles lack the strength needed to complete a workout, you may be low on vitamin D. Soreness, cramps and fatigue are particularly pertinent to vitamin D deficiency if they occur in the thigh and torso muscles.

4. Mood swings or depression

Vitamin D is an important mood regulator so you may find your moods changing quickly or that feel sad for no apparent reason.

5. Impaired wound healing

Vitamin D is essential for wound healing and so you may notice your body takes more time to recover after you get hurt.

6. Hair loss

If you experience hair loss, even when taking good care of your hair and you are free of any genetic hair loss problems, your vitamin D levels may need some attention.

7. Skin conditions

Are itching, rashes, redness or other skin concerns common for you? This is often called the ‘vitamin D itch’, as low levels of vitamin D can often affect skin health.

8. Poor sleep quality

You may notice you are struggling to get good quality, uninterrupted sleep and that you wake up often at night without any reason.

9. Frequent headaches

If you drink enough water, reduce screen time but still have frequent headaches, a vitamin D deficiency may be the culprit.

10. Bone density loss

Do you often end up fracturing your bones, even with minimal impact? Your bones may be losing density, which is a sign of being vitamin D deficient.

11. High blood pressure

You may notice you have high blood pressure, and find yourself quickly developing anger, stress, anxiety and feeling your heart beating faster than normal.

12. Increased susceptibility to infections

Is falling ill a regular fixture for you? Do you always end up catching the flu? Your body may be low on vitamin D.

13. Slowed growth in children

Vitamin D deficiency can extend to kids as well – they may experience issues with bone growth or overall development issues.

14. Respiratory infections

A vitamin D deficiency can make your body more susceptible to contracting respiratory infections like colds.

How can you increase your vitamin D levels

How can you improve your vitamin D levels? A varied diet can help to provide a small proportion of the vitamin D you need. Foods which are high in vitamin D include fatty fish like salmon, mackerel and tuna. Additionally, dairy items such as milk, yoghurt and cheeses contain vitamin D, making them a great dietary addition for all age groups when consumed in moderation. However, if you are a vegan and cannot consume fish or dairy, certain mushrooms like shiitake and fortified foods can give you a plant-based option for your plate.

For people with a more severe vitamin D deficiency, alternate methods of supplementation such as high-dose oral supplements may be beneficial. IV vitamin therapy offers a rapid way of replenishing your vitamin D levels without the worry of taking pills on a daily basis. It’s a great option for those who may be on certain medications and/or face gut health issues which inhibit proper absorption. Vitamin D injections deliver the vitamins directly into the body for faster absorption when compared to oral supplements. Looking for IV vitamin therapy in London? There are plenty of fantastic doctor-led clinics to choose from.

If you think you’re displaying symptoms of a vitamin D deficiency, we recommend consulting your healthcare professional to understand what treatment option is right for you.
