Vitamin D is important for bone and muscle health, but it affects many other aspects of our health.
If these symptoms sound familiar, talk to your doctor about testing your Vitamin D levels and adding a supplement to your routine :
- You are constantly sick. Research suggests vitamin D may affect our immune system.
- You are easily exhausted. Vitamin D’s involvement in the immune system may impact our sleep-wake cycle.
- Your Bone density is declining. Vitamin D helps our bones absorb calcium, which they need to grow and stay strong.
- You have back pain. Vitamin D may be involved in age related muscle and strength loss.
- You are feeling blue. Vitamin D deficiency has been linked to an increased risk of depression later in life.
- Your muscle are always sore. Vitamin D deficiency can deprive our muscle of calcium, which they need to function properly.
- You are losing hair. Some studies have lined hair loss and low vitamin D levels in women.
The best way for doctors to measure how much vitamin D is in your body is with a blood test called the serum 25-hydroxyvitamin D test. Not everyone should get this screening test. Experts recommend it for people at risk of vitamin D deficiency. Your doctor will tell you if you need this test. A test result below 20 nanograms per milliliter (ng/mL) shows you do not have enough vitamin D. You may need to repeat the 25-hydroxyvitamin D blood test during treatment of vitamin D deficiency. This will show your response to treatment.
