Those With Low Levels of Vitamin D Have a Higher Risk of Breast Cancer. Ways to boost your body's level
Having had a the nasty flu that is going around the UK at the moment, I decided it was important for me to boost my Vitamin D levels and seek a little sun this week. Its got me thinking about how essential this vitamin is and yet not much is known about it... or we are too scared of the sun to get the right amounts for us (everyone is an individual and has different needs).
I found some interesting and useful information on the breastcancer.org website:
Vitamin D helps the body absorb calcium, which is essential for good bone health. Vitamin D also helps the immune, muscle, and nervous systems function properly. Most vitamin D is made when an inactive form of the nutrient is activated in your skin when it's exposed to sunlight. Smaller amounts of vitamin D are in fortified milk and other foods, fatty fish, and eggs. As more and more people spend most of their time out of direct sunlight or wearing sunscreen when they are in the sun, vitamin D production from sun exposure is limited.
Research suggests that women with low levels of vitamin D have a higher risk of breast cancer. Vitamin D may play a role in controlling normal breast cell growth and may be able to stop breast cancer cells from growing.
Steps you can take
The two most reliable ways to boost your vitamin D level: get more direct sunlight exposure and take vitamin D3 supplements. Eating foods rich in vitamin D can help, but is less effective.
Sunshine exposure: Even short periods of direct peak sun exposure -- 15 minutes 3 times a week, for example -- can give you more than the recommended daily amount of vitamin D. It's also impossible to overdose on vitamin D from the sun. While sun exposure offers vitamin D benefits, it does have risks. Sun exposure increases your risk of skin cancer, including melanoma, the most dangerous type.
In general, most experts recommend you continue to use sun protection when ultraviolet (UV) radiation levels are moderate or high. UV rays are invisible, so you can't tell if you're exposed or not. The ozone layer protects the Earth from UV rays. But the thickness of the ozone layer changes with the seasons and the weather, so some UV rays get through to the Earth. The U.S. Environmental Protection Agency and the National Weather Service developed the UV Index, which indicates the strength of UV rays on a scale from 1 to 11+ based on zip code.
There are many variables that can affect how much vitamin D you'll produce from sunlight:
- the darker your skin color, the less vitamin D you produce
- the farther you live from the equator, the less vitamin D you produce
- fewer daylight hours mean you produce less vitamin D
All these factors can make is hard to get enough vitamin D from sun exposure alone.

Supplements: Before you adjust your vitamin D intake, it's important to know your vitamin D serum level. This is done with a simple blood test that your doctor can order for you when you're in for a routine physical. Vitamin D researchers recommend a serum level of 40-60 ng/ml (nanograms/milliliter).
Before you take any supplements, talk to your doctor about the risks and benefits of the product, as well as what a good vitamin D serum level is for you. If your level was low and you've been taking a supplement to get back into the normal range, have your vitamin D level checked a few months later and adjust your supplement dose accordingly. Taking too much vitamin D occasionally can cause you to have too much calcium in your blood.
If you're going to take a vitamin D supplement, most experts recommend taking the D3 form of the vitamin, not the D2 form.
The current recommendation is that all people get 600 international units (I.U.) of vitamin D per day, no matter how old they are. The typical multivitamin contains 400 international units of vitamin D.
Foods rich in vitamin D:
- steelhead trout
It's important to choose your fish carefully to avoid any species that may have high levels of mercury. For more information, visit the Exposure to Chemicals in Food page in this section.
Taking 1 to 3 teaspoons of cod liver oil per day as a supplement can also help fulfill your vitamin D requirements. Still, most people don't like the taste of cod liver oil, so you may want to try these other fortified foods (though they have lower levels of vitamin D):
- some yogurt (read the label to see if it says "fortified with vitamin D")
- some orange juice (read the label to see if it says "fortified with vitamin D")
- some soy milk (read the label to see if it says "fortified with vitamin D")
