TL;DR
- Vitamin D deficiency is increasing in the UK, particularly among girls and young women.
- Low vitamin D levels can cause fatigue, dizziness, heart palpitations, and bone pain, potentially leading to conditions like osteomalacia.
- Sunlight is the primary source of vitamin D, but factors like climate, lifestyle, and skin tone affect production.
- Doctors do not routinely test for vitamin D deficiency, and symptoms can be easily missed or misdiagnosed.
- Experts are calling for a raised threshold for classifying vitamin D deficiency and wider food fortification policies, similar to those in Canada and Sweden.
