Low Thyroid Symptoms and Vitamin D

Should you be supplementing with vitamin D?

Dr. Chris Heimlich DC, Director of the Arizona Thyroid Institute in Scottsdale, AZ Explains:

More and more people are taking vitamin D.  They have seen on the news or the web that it is good for them.  Taking vitamin D is good for you…IF YOU NEED IT.

Modern diets are lacking in Vitamin D rich foods.  What are Vitamin D rich foods?  Liver, organ meats, lard, many forms of seafood, butter and egg yolks.

The best-known function of active vitamin D is to help regulate blood levels of calcium and phosphorous. Vitamin D increases absorption of minerals from the gastrointestinal (GI) tract. In combination with parathyroid hormone, it enhances their reabsorption from the kidneys and their mobilization from bones into the blood. Vitamin D helps maintain calcium levels even if dietary intakes are not optimal. Calcitriol affects growth of normal cells and some cancer cells. Adequate vitamin-D status has been linked to a reduced risk of developing breast, colon, and prostrate cancers.

Sunlight is another important factor and source of Vitamin D.  BUT, you should NEVER take vitamin D without having your Vitamin D levels tested, specifically, 25 OHD and 1,25 OHD.  Most doctors only test 25 OHD.  I feel this is a mistake.  It is very important to have both levels tested.  I see at least one patient a week that comes in taking Vit D that have low or normal 25 OHD levels and high 1,25 OHD levels.

Why could it be bad a bad idea to take Vitamin D?  One reason is because it is a fat-soluble vitamin.  That means it is tougher for your body to get excess amounts out of your system.   Vitamin D is most likely to have toxic effects when consumed in excessive amounts through supplementation. Excess vitamin D raises blood calcium levels, resulting in calcium precipitation in soft tissues and stone formation in the kidneys, where calcium becomes concentrated in an effort to excrete it.

Why is Vitamin D so important with patients that have low thyroid symptoms like hair loss, depression, weight gain and fatigue?  Vitamin D deficiency is associated with many, many autoimmune conditions including Hashimoto’s Thyroiditis.  Autoimmune rates have been skyrocketing in the past 20 years and have been correlated with decreased levels of Vitamin D in the general population.

The number one cause of low thyroid in America is an autoimmune disease called Hashimoto’s.

Adequate Vitamin D levels help to keep the immune system balance so it doesn’t swing out of control into an autoimmune disease.  When it comes to Hashimoto’s Thyroiditis, the problems with Vitamin D deficiency is made worse by genetics.  There are studies that show that more than 90 percent of the people with an autoimmune thyroid or Hashimoto’s have a genetic defect affecting their ability to process Vitamin D.

The take home message here is to NOT just take vitamin D because you think it is good for you.  Find a thyroid doctor that can actually do the detective work and find out if it is something that you need.
