Beyond the Sun: The Importance of Vitamin D in Israel and Beyond

Vitamin D is a vital nutrient that exists in two forms – vitamin D2, which is inactive, and vitamin D3, which is the active form created by exposure to the sun. Research has shown that our bodies only produce vitamin D following exposure to UVB radiation, so sunlight exposure is essential for maintaining optimal levels of this important nutrient. This is particularly important in northern countries where sun exposure is limited and can lead to a higher prevalence of vitamin D deficiency.

In Israel, about 70% of the population suffers from low levels of vitamin D, with the elderly being particularly at risk. Vitamin D deficiency can lead to bone fractures, calcium loss, weakness, tooth loss, and even an increased risk of colon and prostate cancer. To maintain optimal levels of vitamin D, it is recommended that individuals undergo regular tests to detect any potential deficiencies and take daily supplements if necessary. Health insurance funds typically cover these tests every two years with a recommended daily intake of about 1,000 units for individuals over the age of 65.

To ensure daily vitamin D intake, it is recommended to expose hands to direct sunlight for around ten minutes a day during peak hours or use a tanning bed or supplements that contain this important nutrient. It is also crucial to monitor vitamin D levels regularly through tests every few years to detect any potential deficiencies and address them promptly. Regular monitoring can help prevent long-term health issues associated with low levels of this important nutrient.
