In this video Dr O'Donovan explains key things you need to know about Vitamin D deficiency.

What is 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.

What happens when you don't get enough Vitamin D?

Severe lack of vitamin D in children causes rickets. Symptoms of rickets include:

Incorrect growth patterns due to bowed or bent bones.
Muscle weakness.
Bone pain.
Deformities in joints.

This is very rare. Children with a mild vitamin deficiency may just have weak, sore and/or painful muscles.

Lack of vitamin D isn’t quite as obvious in adults. Signs and symptoms might include:

Fatigue.
Bone pain.
Muscle weakness, muscle aches or muscle cramps.
Mood changes, like depression.

However, you may have no signs or symptoms of vitamin D deficiency.

UK government advice is that everyone should consider taking a daily vitamin D supplement during the autumn and winter.

People at high risk of not getting enough vitamin D, all children aged 1 to 4, and all babies (unless they're having more than 500ml of infant formula a day) should take a daily supplement throughout the year.

Causes:
Vitamin D deficiency is often linked to insufficient sun exposure, as sunlight helps the body produce vitamin D. Individuals who wear extensive clothing, use sunscreen regularly, have darker skin, or are obese may be at higher risk. Additionally, poor dietary intake of vitamin D-rich foods and conditions that affect absorption, like malabsorption disorders or kidney/liver disease, can contribute to the deficiency.
