Vitamin D is important for the absorption of calcium from your stomach and for the functioning of calcium in your body. This helps your bones to stay healthy and your muscles to work well.
- Low levels of vitamin D are linked to bone conditions such as rickets in children and osteoporosis and osteomalacia in adults.
- Low vitamin D levels may also be linked to non-skeletal health conditions, such as colorectal cancer, cardiovascular disease and immune system problems. Researchers are looking into whether increasing vitamin D levels could help prevent any of these conditions, but the evidence is not clear at this stage.
- Vitamin D has been shown to help reduce falls and fractures in older people in residential care. More research is needed to see if vitamin D could help reduce falls and fractures in other groups of people.
- However, too much vitamin D replacement can lead to high levels, which can actually increase your risk of falls. For this reason, you should only take vitamin D as recommended and prescribed by a doctor.
