Certain Illnesses And Conditions

“Certain illnesses can prevent the metabolism of vitamin D at numerous stops along its journey to getting where it’s needed in the body, like kidney and liver disease,” Dr. Mao says. Those with type 2 diabetes may have reduced vitamin D absorption, and so do gastric bypass patients. Bariatric patients sometimes risk becoming vitamin D deficient, too, as the portion of their stomach that is removed is the upper small intestine, which is where the majority of vitamin D is typically absorbed in the body.

Final Thoughts About Vitamin D3

In general, most people need between 600 and 800 IU of vitamin D per day to maintain healthy blood levels. However, some people may need more or less than this, so it’s important to speak to a healthcare professional before starting any supplement regimen.

Vitamin D is an important nutrient for overall health, so it’s important to make sure you’re getting enough. If you’re not sure how much you need, speak to a healthcare professional to find out. They can help you determine the right dose for you based on your individual needs.

Check Your Supplements More Isnt Always Better

For Portlanders, moderate deficiency in the sunshine vitamin is about as common as a cloudy day. Since we cant get the daily sun exposure needed to synthesize our own vitamin D year-round, many of us pop a supplement to keep our levels in check and in most cases, thats a good thing. But in some cases, we could be taking too much and that can be a problem.

You need vitamin D to help you absorb calcium, among other benefits. But extra high blood levels of vitamin D may encourage your body to stash extra calcium where its not wanted in your kidneys, for example, which is why high levels of vitamin D make you more vulnerable to kidney stones. Calcium deposits in the arteries are another potential concern. High vitamin D levels also can cause nausea, vomiting, muscle weakness, confusion, loss of appetite, dehydration and frequent urination.

When people have too much vitamin D in their blood, its almost always caused by over-use of dietary supplements. That doesnt mean you should stop taking vitamin D altogether, but do take a closer look at how much youre taking to make sure youre not overdoing it.

Enough vs. too much where do you draw the line?

The recommendations may vary depending on your age, health, ethnicity and even whom you ask. But as a general guideline, the National Institutes of Health Office of Dietary Supplements recommends getting 15 mcg of vitamin D daily from the age of 1 through 70, and 20 mcg from age 71 on.

Two ways we get into trouble

Is It Best To Get Your Vitamin D From The Sun Definitely Not

David J. Leffell, MD, Yale Medicine dermatologist and chief of Dermatologic Surgery

One of the biggest challenges weve faced in dermatology and in the world of skin cancer prevention has been a lot of misinformation about vitamin D metabolism.

There are claims that one needs to get a certain amount of sun exposure every day in order to produce enough vitamin D to be healthy. Its just not true. The majority of people can get their vitamin D from nutritional supplements and from vitamin D-fortified foods.

There are some people who have advocated for tanning to get vitamin D. But we know that UVB light causes skin cancer and that protecting yourself against it makes sense. As a doctor who treats patients who have melanomas, I want the general public to be advised that under no circumstances can use of a tanning bed or tanning in general be justified on the basis of vitamin D. Take a supplement instead.

Men and women relying on sourcing vitamin D through diet alone typically dont exceed 288 IU a day on average.

Optimal Vitamin D Dose With Blood Test

If you suffer from a disease that makes it absolutely necessary for your vitamin D level to be in the optimal range, or if you want to know your exact level, then you should have your vitamin D level measured. The blood test to measure your vitamin D levels is called the 25D blood test.

The result of the blood test helps determine how much vitamin D you should take in the form of vitamin D capsules or vitamin D drops, etc., or whether you should increase your exposure to the sun in order to build up an optimal vitamin D level.

Since everyone absorbs vitamin D differently, the 25D value may develop differently. This means that not ever person will achieve exactly the same 25D level in their blood even if they take the same dose of vitamin D.

The following recommendations represent guidelines on how your vitamin D blood levels could increase when taking the respective amount of vitamin D. Therefore, this information should not be regarded as a guarantee for the specified values.

About 3 months after you begin taking your dose, you should have your vitamin D level re-measured to check on things. Once you have the result, you can assess how your vitamin D level has changed during the time you’ve been taking it, as well as to what extent the dose should be adjusted.
