Symptoms of vitamin deficiency

Vitamin B12 – Recognisable signs

Do you often experience fatigue, muscle weakness or muscle pain? Do you regularly feel short of breath or breathless? These can be signs of a vitamin B12 deficiency. Other possible symptoms include low mood, confusion, difficulty concentrating, memory problems and difficulty finding the right words. A B12 deficiency can have a significant impact on your energy levels, mood and cognitive function.

Folic acid – Essential for your wellbeing

A folic acid (vitamin B9) deficiency can manifest in several ways. Do you often feel tired? Do you experience digestive problems, reduced appetite or unexplained weight loss? These may be possible signs. A deficiency can also affect your immune system, potentially making you more susceptible to infections. Folic acid plays an important role in the production of new cells and supports a properly functioning immune system.

Vitamin D – Essential for energy and balance

Do you experience sleep problems, fatigue or a persistent lack of energy? A vitamin D deficiency may contribute to these symptoms. Low mood, joint pain, muscle problems, hair loss and weakened bones can also occur with low vitamin D levels. This vitamin plays an important role in energy metabolism, mood, immune function and bone health.

Biomarker summary

Vitamin B12 – Essential for energy and health

Around 1 in 10 people in Western countries has a vitamin B12 deficiency. With the growing popularity of vegetarian and vegan diets, this number may increase, as vitamin B12 is naturally found mainly in animal-derived foods such as meat, fish, dairy products and eggs. Your body can store B12, so a deficiency often develops gradually and may go unnoticed for some time. Symptoms can take months to appear and range from fatigue and shortness of breath to chest pain and loss of appetite. In more severe cases, a specific type of anaemia can develop. Memory and concentration problems may also occur, particularly in older adults. If you want to find out whether you may have anaemia, consider an additional anaemia test alongside the vitamin test.

Folic acid (vitamin B9) – Important for everyone

Folic acid is an essential vitamin that your body cannot produce itself, so you depend on your diet and supplements for your intake. Although a varied diet is recommended, deficiency still occurs regularly in Western countries. Good sources of folic acid include leafy green vegetables, fruit, whole grains and legumes. A deficiency can cause symptoms such as fatigue, reduced appetite, weight loss and reduced resistance to infections. The recommended daily intake for adults is 300 micrograms. During pregnancy, the recommended intake is higher: at least 400 micrograms per day, regardless of dietary habits.

Vitamin D – Sunlight, diet and your immune system

Vitamin D is a hormone-like vitamin that is essential for the absorption of calcium and phosphate, which are important for strong bones and teeth, muscle function and a properly functioning immune system. Your body produces vitamin D mainly through exposure to sunlight. You can also obtain it through food, particularly fatty fish, eggs, dairy products and fortified foods. Some mushrooms also contain vitamin D. Despite these sources, many people, particularly during autumn and winter, have low vitamin D levels without knowing it.

Results

How quickly will you receive your results?

Once you have completed the vitamin test and your blood sample has arrived at the laboratory, you will generally receive your results within one working day. Your results are shared via your personal online dashboard, with a secure link sent to you by email.

What should you do if you have a vitamin deficiency?

If the test shows that you have a deficiency in one or more vitamins, start by reviewing your diet. A varied diet containing sufficient vegetables, fruit, grains, dairy products, meat or meat alternatives can often provide many of the vitamins your body needs. If you are not getting enough through your diet or sunlight, supplements from a pharmacy or drugstore may be a useful addition. If in doubt, consult a doctor or dietitian.

How do you interpret your results?

The test provides insight into your levels of vitamin B12, vitamin D and folic acid (B9). You can see whether your levels are within the recommended ranges or whether a deficiency may be present. Test results provide a snapshot in time and can be influenced by factors such as diet, lifestyle, medication and the time of sample collection. Abnormal results do not automatically mean that you have a medical condition. If your results are abnormal, you can take targeted action by adjusting your diet, considering supplements or, if necessary, seeking medical advice.

Frequently Asked Questions Everything about Vitamin deficiency test

At the moment, we do not have agreements with health insurance providers. At Labtest.nl, we aim to keep our checks as affordable as possible, so you can gain more insight into your own health.

A vitamin deficiency is more common than you might think.

  • Around 10 to 15% of people have a deficiency in vitamin B12 or folic acid.
  • Vitamin D deficiencies are even more common, especially during winter. At that time, around 59% of people have a level that is too low. In summer, this decreases to approximately 35%.

A deficiency is not always immediately noticeable, but it can affect your energy levels, immune system, and overall health. If you have symptoms or are unsure, it is a good idea to discuss this with your doctor or take a test.

A vitamin deficiency is usually caused by:

  • Poor diet – you do not get enough vitamins from your food
  • Too little sunlight – especially important for vitamin D
  • Medical conditions – such as intestinal problems that reduce the absorption of vitamins
  • Certain medications – which can interfere with the absorption or function of vitamins
  • Excessive alcohol consumption – which can reduce the absorption and storage of vitamins

A healthy and varied diet, spending enough time outdoors, and proper medical guidance can help prevent vitamin deficiencies.

With a vitamin test from Labtest.nl, you can easily gain insight into your health from the comfort of your own home. You do not need to make an appointment with your doctor or visit a testing location, and you will quickly receive a reliable result with a clear explanation.

This allows you to stay in control of your wellbeing while saving time. It makes it easier to take good care of yourself.

A vitamin deficiency can lead to various complaints, such as fatigue, muscle weakness, low mood, or a reduced immune system. If the deficiency continues for a longer period, more serious health problems may develop, such as:

  • Anaemia (due to a deficiency of vitamin B12 or folic acid)
  • Bone loss (due to a vitamin D deficiency)
  • Nerve problems
  • Delayed wound healing

Not only deficiencies can be harmful; an excess of certain vitamins, such as vitamin D, can also cause health problems.

If you have symptoms or are unsure about your vitamin intake, consult your doctor.

Yes, the laboratory test from Labtest.nl is much more accurate than most rapid tests available at pharmacies. With Labtest.nl, your blood sample is professionally analysed in a certified laboratory. You receive a detailed report with your exact vitamin D level, allowing you to take targeted action if needed.

Many home tests available in stores only provide a positive or negative result, without showing exact values. This provides less insight into how severe a possible deficiency may be. If you want to know exactly where you stand, a laboratory test is the best choice.

Yes, definitely. If you follow a vegetarian or vegan diet, it is important to monitor your vitamin intake carefully. Some vitamins, such as vitamin B12, are naturally found almost exclusively in animal products. Deficiencies are therefore more common among people who eat a plant-based diet.

Vitamin D and folic acid are also important to check regularly. A vitamin check gives you insight into your levels, so you know whether additional intake through diet or supplements may be needed.

Yes, all self-tests have been carefully researched and approved for reliable use at home.

Blood tests for vitamins are generally reliable and accurate, especially when they are performed correctly in a certified laboratory. They can usually provide a good indication of whether you have a deficiency or whether your vitamin levels are within the normal range.

However, factors such as your diet on the day of testing, medication use, or certain medical conditions can sometimes influence the results. If there is any uncertainty, your doctor may repeat the test or combine it with other examinations to get a clearer picture.

You may not immediately notice that you have a vitamin deficiency. However, there can be certain signs, such as:

  • Fatigue or low energy
  • Poor sleep
  • Difficulty concentrating
  • Feeling low or being more irritable

When your body does not get enough vitamins and minerals, it may not function optimally. If you have ongoing symptoms or suspect a deficiency, discuss this with your doctor. They can perform blood tests if needed and provide further advice.

Yes, our home tests are scientifically validated and approved for use at home. They have been extensively tested to ensure that a finger-prick sample collected at home provides results that are just as reliable as a blood sample taken by a doctor or at a testing location.
