Vitamin D

Vitamin D helps regulate the amount of calcium and phosphate in the body.
These nutrients are needed to keep bones, teeth and muscles healthy.

Vitamin D

A lack of vitamin D can lead to bone deformities such as rickets in children, and bone pain caused by a condition called osteomalacia in adults.
Everyone should consider taking a daily vitamin D supplement during the autumn and winter, since we do not make enough vitamin D from sunlight.
Between late April to the end of September, most people can make all the vitamin D they need through sunlight on their skin and from a balanced diet.You may choose not to take a vitamin D supplement during these months.
People at high risk of not getting enough vitamin D, should take a daily supplement throughout the year. You should follow doctors advice.
Vitamin D is also found in a small number of foods: red meat, eggs, fish (salmon, sardines...), liver..., however it is difficult to get in enough from the food.

The Recommended Dietary Allowance (RDA):
- for adults 19 years and older is 600 IU (15 mcg = 15µg) daily for men and women,
- for adults >70 years it is 800 IU (20 mcg = 20µg) daily.

The Tolerable Upper Intake Level (UL) is the maximum daily intake unlikely to cause harmful effects on health. The UL for vitamin D for adults and children ages 9+ is 4,000 IU (100 mcg = 100µg).
