6 Signs You’re Deficient in Vitamin D
Vitamin D deficiency is one of the most common nutritional problems faced by people around the world, especially those living in northern countries where sunlight is particularly scarce. This vitamin plays a vital role in our body’s functions, from strengthening bones to supporting the immune system. Despite its importance, many people don’t even know they’re deficient in this vital vitamin, as symptoms are often subtle and can easily be mistaken for other health problems.
Today, we’ll look at the six main signs of vitamin D deficiency, discuss why this vitamin is so important for our bodies, find out who is at risk, and learn how to improve your vitamin D levels. Modern trends show that people are increasingly looking for convenient ways to supplement their diet, such as choosing vitamin gummies, which are an easy way to get daily nutrients, including vitamin D.
Why is vitamin D important for your body
Vitamin D is unique in that our body can produce it on its own when the skin is exposed to sunlight. However, sunlight alone is not always enough, especially in winter or when living in northern latitudes. This “sunshine vitamin” performs a number of important functions:
- regulates the absorption of calcium and phosphorus, which are essential for bone health
- boosts immunity and helps the body fight infections
- maintains muscle function and strength
- participates in the activity of the cardiovascular system
- regulates mood and can help prevent depression
According to the World Health Organization, the optimal concentration of vitamin D in the blood should be at least 30 ng/ml. Unfortunately, studies show that vitamin D deficiency is extremely common in northern European countries, including the Baltic region, especially during the darker seasons.
The following groups are most at risk of vitamin D deficiency:
- older people (over 60)
- people with darker skin pigmentation
- people who spend a lot of time indoors
- people living in northern regions
- those with digestive problems
- vegans and vegetarians
6 main symptoms of vitamin D deficiency
Vitamin D deficiency can manifest itself in many ways, from subtle changes to more serious health problems. Here are six common signs to look out for.
Fatigue and lack of energy
Persistent fatigue and lack of energy can be one of the first symptoms of vitamin D deficiency. If you feel tired even after a good night’s sleep or experience unusual weakness in daily activities, this could be a sign that your body is lacking vitamin D.
This vitamin is involved in the activity of mitochondria (the energy generators of cells), so its deficiency directly affects our energy levels. Many people who start taking vitamin D supplements notice a significant increase in energy and an overall improvement in well-being.
Muscle and bone pain
Vitamin D is essential for the absorption of calcium, a mineral that builds our bones and supports muscle function. When the body lacks vitamin D, bones can become weaker and muscles can become painful.
If you experience persistent or recurring bone pain, especially in the back or pelvic bones, this may be a sign of vitamin D deficiency.
Also pay attention to unexplained muscle pain or general muscle weakness. Long-term vitamin D deficiency can contribute to the development of osteoporosis, especially in older people.

Mood swings and depression
More and more scientific research confirms the link between vitamin D deficiency and mood disorders. Vitamin D is involved in the production of serotonin, the “happiness hormone”, so a deficiency in it can cause mood swings and even depression.
Seasonal affective disorder (SAD), also known as “winter depression”, is often associated with a lack of vitamin D due to reduced sunlight during the darker months of the year. If you notice that your mood significantly worsens during the winter months, you may be experiencing a vitamin D deficiency.
Frequent infections or illnesses
Vitamin D plays a crucial role in strengthening the immune system. It helps immune cells fight pathogens more effectively and reduces inflammatory reactions in the body. When vitamin D levels are insufficient, the body becomes more vulnerable to infections.
If you notice that you often get colds, flu, or other infections, this may be a sign that your immunity is weakened due to a lack of vitamin D.
Studies show that adequate vitamin D levels can reduce the risk of upper respiratory tract infections and ease their symptoms.
Hair loss and brittleness
While hair loss can be linked to a number of factors, vitamin D deficiency is often a contributing factor. Vitamin D stimulates hair follicles and promotes new hair growth.
In women, especially after giving birth, hair loss can be linked to a vitamin D deficiency. If you notice increased hair loss or brittleness, it’s a good idea to get your vitamin D levels checked and adjusted if necessary.
Slow wound healing or skin problems
Vitamin D is involved in the process of skin cell renewal and helps the body fight inflammation. When it is deficient, wound healing can slow down and the skin can become more prone to various problems.
If you notice that even small wounds or scrapes are taking longer than usual to heal, this could be another sign of vitamin D deficiency.
Vitamin D deficiency is also associated with skin conditions such as eczema and psoriasis, the symptoms of which may improve with vitamin D supplementation.
Who is most at risk of having a vitamin D deficiency
Although vitamin D deficiency can affect anyone, certain groups of people are more vulnerable for specific reasons:
- Residents of Nordic countries – due to limited sunlight, especially in the autumn-winter period
- Older people (over 60) – the skin becomes less efficient at producing vitamin D from sunlight
- People with darker skin pigmentation – melanin makes it difficult to produce vitamin D
- Those who spend a lot of time indoors – receive little natural sunlight
- Vegan and vegetarians – many natural sources of vitamin D are animal products
- People with overweight problems – vitamin D accumulates in fatty tissue and becomes less available to the body
- People with malabsorption syndromes – those with celiac disease, inflammatory bowel diseases
- Pregnant and breastfeeding women – the need for vitamin D increases
Various options are now available for those who want to take care of their health, including specialized vitamin and food supplement stores, where tailored solutions can be found based on individual needs, especially for at-risk groups.
How to restore healthy vitamin D levels
If you notice symptoms of vitamin D deficiency, you can take various measures to improve the situation:
Sunlight – a natural source of vitamin D
Sunlight remains the most effective natural source of vitamin D.
Recommended:
- 15-20 minutes of daily outdoor exposure to exposed skin on your hands and face (without sunscreen)
- The best time to spend outdoors is between 10 a.m. and 3 p.m.
- Try to make the most of every sunny day during the winter months
- Don’t overdo it – prolonged exposure to the sun without protection increases the risk of skin cancer
It is important to understand that in the Baltic region, the intensity of sunlight from October to March is insufficient for effective vitamin D production.
Food sources
Although vitamin D is relatively low in food, the following foods can help replenish its stores:
- Fatty fish – salmon, mackerel, herring, tuna
- Fish oils – especially cod liver oil
- Egg yolks
- Mushrooms (especially those kept in the sun)
- Fortified products – milk, yogurt, herbal drinks, cheese, cereals
Food supplements
For many people, especially those living in northern countries during the winter months, vitamin D supplements are becoming a necessity. When choosing supplements, it is important to pay attention to:
- the form of vitamin D (the D3 form is better absorbed than D2)
- the dose (the recommended daily intake ranges from 800 IU to 2000 IU depending on age and health condition)
- supplements that also contain other substances that improve the absorption of vitamin D (e.g. vitamin K2 and magnesium)
If you suspect a vitamin D deficiency, it is recommended to consult a doctor and check the level of vitamin D in the blood before starting to take supplements. Convenient home tests, such as vitamin D test kits, are also available to help you monitor your condition and take the necessary measures in a timely manner.
Vitamin D test
The only way to determine your exact vitamin D level is to have a blood test. The test results are interpreted as follows:
- Less than 20 ng/ml – deficiency
- 20-29 ng/ml – insufficient level
- 30-50 ng/ml – optimal level
- More than 100 ng/ml – potentially toxic level
It is recommended to have a vitamin D test periodically, especially for people at risk – at least once a year, ideally in late autumn or early winter, when the body’s natural vitamin D stores decrease.
Vitamin D Supplementation Tips
Vitamin D supplements are safe for most people, but it is important to:
follow the recommended dosage
- take vitamin D supplements with a meal containing fat (improves absorption)
- avoid overdose, which can cause hypercalcemia (too much calcium in the blood)
- always consult your doctor if you are taking other medications or have certain health problems
Remember that vitamin D levels in the body increase gradually, so you may only notice an improvement after several weeks or months of consistent supplementation.
Conclusions
Vitamin D deficiency is a common but often unrecognized problem, especially in the Baltic and Northern European regions. Six main symptoms – fatigue, muscle and bone pain, mood swings, frequent infections, hair loss and slow wound healing – can signal a vitamin D deficiency in the body.
Depending on your geographical location, age and lifestyle, it is important to take proactive measures – regular sun exposure, including foods rich in vitamin D in your diet and taking supplements if necessary. Periodic testing of vitamin D levels will help ensure optimal levels of this important vitamin in the body.
Remember that healthy vitamin D levels are not only the basis of bone health, but also of general well-being, immunity and mood. Pay attention to the signals your body sends and take immediate action if you suspect a vitamin D deficiency.
