Fatigue


Constant Fatigue Effects Many of Us

Studies have revealed that 15% of people are constantly tired – and they don’t know why. It is not only a lack of sleep that can make you tired and weary throughout the day; a change in your sleeping pattern or a lack of nutrients can also sometimes cause your body to flag while you are awake.

We need good sleep to promote a healthy immune system, cell growth, and general wellbeing – and even a better sex life. It is only right, then, that we do not underestimate the importance of good sleep. Over time, sleep deprivation could lead to more long-term health conditions, such as high blood pressure, obesity, anxiety, and depression

This is why we want to help you get to the bottom of your fatigue – so you can overcome daily tiredness and boost your overall health in the long term. With our home test kits, you can measure different nutrient levels, hormones, and other biomarkers, the analyses from which will help you devise a targeted plan of action to combat your fatigue.

Why am I Constantly Tired?

Digging into the causes of fatigue

Sure, if you suffer from constant fatigue, you may simply not be sleeping enough. Unfortunately, many get good sleep and still go about their feeling worn out. It affects concentration, productivity, mood, and energy levels.

This sluggishness or fatigue may be linked to a certain nutrient deficiency. In other words, your body's fuel is running low - on reserve energy! Your body needs energy, vitamins, and minerals, among other things, so that it is a fully and optimally functioning well-oiled machine.

There may be additional factors affecting your ability to sleep, such as the occurrence of emotional events in your life – for example, a breakup or loss, or if you suffer from depression, stress, or anxiety.

Vitamin D: Good for Catching ZZZs

Vitamin D deficiency is a common problem, with constant fatigue recognized as a typical symptom. If you want to know whether you have low vitamin D levels, a blood test will help. Laboratories can measure the concentration of vitamin D3 in your blood sample; this is the active form of the vitamin. One such blood test is the cerascreen® Vitamin D Test.

Nutrients related to fatigue

Analyze Vitamin and Mineral Levels

If it is not vitamin D your body is lacking, a whole range of other nutrient deficiencies could be the cause of your constant fatigue. If you lack minerals such as zinc and magnesium, iron, iodine, or vitamin B12, this can also make you tired and low on energy.

For these nutrients, you can find blood tests in our online shop. Such tests include the Ferritin Test, which tests for iron deficiency.

Testing for Causes of Fatigue

Home Test Kits: Where to Start

Are you constantly tired and don’t know which test to start with? Maybe you belong to a risk group prone to certain nutrient deficiencies. For vegetarians and vegans, for example, you should regularly take a vitamin B12 test. An iron deficiency test is also a good idea if you do not eat meat. An iodine deficiency test could prove especially interesting for women, smokers, and people with gastrointestinal diseases.

Last but not least, you might benefit from checking your sleep hormone levels with a melatonin test. If your sleep hormone levels are noticeably low in the evening, this may indicate that your body clock has shifted or that you are simply a natural night owl’. Both can lead to constant tiredness in everyday work and family life.

Establishing a healthy sleeping pattern can help you to live better according to your inner body clock. These include, for example, not eating dinner too late, avoiding smartphone screen time before going to bed, and going to bed and waking up at similar times every day.
