Vitamin D


What is Vitamin D and why is it important?

  • Vitamin D is a fat-soluble vitamin found in certain foods. It can also be made by our bodies after exposure to sunlight.
  • Vitamin D helps your body maintain normal levels of calcium and phosphorous in your blood.
  • Together, Vitamin D and calcium are essential for strong, healthy bones. They can help prevent osteoporosis.

Am I at risk for low Vitamin D levels?

  • Everyone can benefit from a little more Vitamin D, but certain people may be at risk for low levels. Consider additional Vitamin D supplementation if you:
    • are over 50 years old
    • have been diagnosed with low bone density
    • get very little sun exposure
    • have kidney disease or another disease that affects absorption of minerals
    • are lactose intolerant
    • are vegan
    • have darker skin

How much Vitamin D do I need?

  • Current guidelines suggest that women get 1,000 IU (international units) of Vitamin D3 each day.
  • Sometimes, higher doses of Vitamin D may be recommended.
  • Unless specifically instructed by your healthcare provider, you should not take more than 2,000 IU per day.

Is there anything I should consider before starting Vitamin D?

  • Vitamin D can interact with some medications (such as drugs for high blood pressure and heart problems). If you take daily medications, check with your doctor before starting Vitamin D supplements.
  • Taken at normal doses, Vitamin D has very few side effects.
  • Signs of a possible overdose of Vitamin D include:
    • Nausea
    • Vomiting
    • Weakness
    • Constipation
    • Unexplained weight loss
    • Disorientation
    • Kidney or heart problems

Where can I get Vitamin D?

  • The best way to get Vitamin D is through sunlight. Just 10-15 minutes of sun exposure (without sunscreen) a couple times a week is usually enough to maintain adequate levels of Vitamin D. But we live in Oregon, so…
  • Vitamin D can also be found as a vitamin supplement. You can find Vitamin D tablets or capsules at most drug stores. Oral Vitamin D pills are sold in two forms: Vitamin D2 and Vitamin D3. Vitamin D3 seems to have a stronger effect, so try to find this form.
  • There are a few foods that contain Vitamin D naturally and some others that have had Vitamin D added to them (like fortified milk or cereals). The list below can give you a good idea where to get Vitamin D in your food:

July is Group B Strep Awareness Month

Group B Strep is a bacterial infection that is found in approximately 25% of all normal, healthy women. Most women who test positive do not have any symptoms. A woman who is pregnant and tests positive for GBS, however, has the possibility of passing GBS to her baby during delivery. Some, but not all babies exposed to GBS during delivery can become quite ill.
A routine part of testing during pregnancy includes Step B testing during a patient’s initial OB lab panel. Patients are also screened during the 36th week of pregnancy. If a woman is found to be positive, steps can be taken during labor to prevent GBS from being passed on to her baby.
