About the Test

The Sunshine Vitamin Check

The best measure of your vitamin D status is the 25-hydroxy vitamin D level in your blood. It reflects what you get from sunlight, food and supplements combined.

🦴
Bone and Muscle Health
Vitamin D helps your body absorb calcium. Low levels can cause bone pain, muscle weakness, and in the long term osteoporosis or rickets in children.
🛡️
Immunity and Energy
Deficiency is linked with frequent infections, low mood and persistent tiredness — symptoms that are easy to blame on other things.
📊
Deficient, Low or Adequate
Results are grouped as deficient, insufficient or adequate. Your doctor uses the number to choose a supplement dose and decide when to retest.
When to Test

Five Reasons to Get a Vitamin D Test

01
Bone Pain or Muscle Weakness
Aching bones, cramps or difficulty climbing stairs can point to low vitamin D.
02
Constant Tiredness
Unexplained fatigue is one of the most common reasons for a vitamin D check.
03
Limited Sun Exposure
Office workers, people who cover most of the skin, and those who rarely go outdoors are at higher risk.
04
Pregnancy, Older Age or Bone Disease
Pregnant women, older adults, and people with osteoporosis or a history of fractures benefit from knowing their level.
05
Monitoring Supplements
If you are already taking vitamin D, testing shows whether your dose is working or too high.
