As a doctor, I frequently encounter vitamin D deficiency in my patients. It is a widespread societal issue that affects all age groups. A lack of vitamin D has a significant impact on health and the immune system.
Practical Experience
Immune System:
- Patients with low vitamin D levels are more susceptible to infections, especially respiratory illnesses.
- During flu epidemics, vitamin D deficiency is a risk factor for more severe illness.
- Adequate vitamin D levels are essential for proper immune cell function and regulation of inflammatory processes in the body.
Bones and Muscles:
- In older patients, vitamin D deficiency leads to muscle weakness and an increased risk of falls.
- In children, it can cause rickets, a disease that leads to bone deformities.
- In postmenopausal women, vitamin D deficiency is a risk factor for osteoporosis.
Other Health Issues:
- Low vitamin D levels are associated with an increased risk of cardiovascular diseases, diabetes, autoimmune diseases, and certain types of cancer.
- I often see patients suffering from depression, and after measuring their vitamin D levels and introducing supplementation, their condition significantly improves.
Recommendations
I advise all patients to have their vitamin D levels checked regularly, especially in winter. It is important to note that excessive vitamin D intake can also be harmful. If there is a deficiency, taking dietary supplements is advisable. Supplement dosage should be individualized and determined by a doctor based on laboratory results.
Sources of Vitamin D
Sunlight:
The best natural source of vitamin D. However, in our geographical location, sunlight is insufficient during winter months.
Food:
Fatty fish, egg yolks, beef liver. However, food contains only limited amounts of vitamin D.
Supplements:
The most reliable way to ensure adequate vitamin D intake.
Vitamin D is crucial for health and immunity, so maintaining sufficient intake is essential.
