Symptom-Check:

Eye problems

If the eyes cause problems, those affected may see worse. But many other complaints are also possible. For example, it often happens that the eyes become too dry, which leads to itching and burst veins. This can also be related to the diet - a lack of vitamins A, B12 and D can probably contribute to dry eyes. Certain nutrients and diseases such as diabetes are also related to the risk of developing macular degeneration in old age that weakens our eyesight and can lead to blindness. On this page we recommend tests with which you can track down some possible causes of eye problems. Click below which other symptoms and properties apply to you and receive tailored recommendations.

About

Vitamin B12 is an essential vitamin. This means that the body cannot produce it or cannot produce it to a sufficient degree by itself. Tiredness, exhaustion, headaches, difficulty concentrating, digestive problems and depression can all be signs of a low vitamin B12 level. People with high stress levels, vegans, vegetarians, pregnant women and elderly people all have an increased risk of vitamin B12 deficiency.

Vitamin B12 is involved in cellular energy production and can thus support physical performance.
