What exactly is vitamin D?
First, we need to clarify something: Vitamin D is not, strictly speaking, a vitamin, but a hormone. Our body can produce it itself with the help of solar radiation. The UV-B rays in sunlight ensure that a precursor of vitamin D is converted into vitamin D3. You can also find this form of vitamin D in high-quality food supplements.
Vitamin D is vital because it performs many functions in the body. For example, it is needed for the absorption of calcium and phosphorus. This helps maintain healthy bones. And our immune system also needs vitamin D to function normally.
It is also involved in the production of serotonin². This is a neurotransmitter in the brain that transmits signals between nerve cells. It is also known as the “feel-good maker” because it can activate the reward center of our brain.
People suffering from a vitamin D deficiency often show the following typical symptoms:
- Susceptibility to infection
- Muscle cramps and weakness
- frequent exhaustion
- mild irritability
- Depression and other mental disorders
- Bone problems
Bone problems are one of the most common symptoms of vitamin D deficiency. Even in children, bone softening, known as rickets, can occur.
In older people, a lack of vitamin D can lead to osteoporosis. This is the medical term for a reduction in bone mass, which causes bones to become brittle.
The good news is that bone problems only occur when there is an acute, long-term deficiency. All other symptoms, however, can occur even if the vitamin D supply is not optimal.
The most common causes
- Too much time indoors

- Dark skin tone
- Taking certain medications
- Stomach, intestinal, liver and kidney diseases
