This vitamin is also known as D3 or 1,25 dihydroxy-cholecalciferol. The lab work that you get done for your medical doctor no longer includes measuring vitamin D levels. There is a charge for this, so if you feel you need to know then request your level and pay the required amount.

Optimal levels of vitamin D should be around 75 to 90 nmol/L or 30 to 40 ng/mL. Vitamin D aids in cancer prevention, bone metabolism and calcium absorption, immune function, joint and muscle pain, MS, diabetes and seasonal depression.

If you work night shift or are unable to get outside much or are experiencing any of the above then please ask for your level.

Our climate does not provide adequate sun exposure times through out the year and with the UV protection requirement there are fewer exposure times. Foods that contain vitamin D include fish, egg yolks, beef liver, cheese and mushrooms.

Taking some vitamin D during the winter months is always a great idea but even better is to know your level to begin with. If you feel like your immune system has been weak, then add some vitamin D to your vitamin protocol. If you have a diagnosis of cancer then it is extremely important to have your level checked. Women who are older than 50 should have their vitamin D checked as bone health and osteoporosis prevention requires adequate amounts of vitamin D.
