Thyroid Medication and Strontium

Research / February 17, 2015

Lara Pizzorno is the author of “Your Bones: How You Can Prevent Osteoporosis and Have Strong Bones for Life – Naturally” and a member of the American Medical Writers Association with 29 years of experience specializing in bone health.

Recently we asked Lara if she would help us provide a series of short, ongoing videos to help you (our customers and readers) stay up to date on the latest facts and science related to bone health and overcoming osteoporosis naturally.

In this latest video, Lara discusses whether or not you can take a thyroid medication and strontium supplement at the same time (of day). Watch the video below (or read the transcript provided) and let us know what you think in the comments. 🙂

 

 

Hello, my name is Lara Pizzorno and I’m here to answer some questions that were sent into me after we taped the first series of videos on bone health. And I hope this information will be helpful for you. I’m only answering one question per video, they were great questions and a lot of information needed to be provided in response to to them. So if your question is not answered in this video, hang on, it will be answered in one of the next ones.

So this question was sent in: “I take a thyroid medication first thing in the morning and I’ve heard not to take calcium at the same time, but is it ok for me to take strontium at the same time as my thyroid medication?”

In brief, no.

You do not want to take strontium at the same time as you take your thyroid medication.

It’s best to take your thyroid hormone on an empty stomach, an hour or more before you take any other medication or supplement or eat any other food (have breakfast or whatever). Because the presence of other food, medications or supplements in the stomach, will affect the absorption of the thyroid hormone. It’s probably easiest to take your thyroid hormone early in the morning, but nighttime dosing works as well. Sometimes taking your thyroid hormone at night can make it simpler to provide your thyroid hormone from interacting with food, supplements or other medications that you need to take. But the most important thing is to be consistent and to take your thyroid hormone at the same time and the same way everyday.

There are a number of minerals, food products and medications, not just calcium, that can prevent the absorption of your full dose of thyroid hormone. These include iron, calcium as noted, soy products, coffee, antacids that contain either aluminum or magnesium, proton pump inhibitors such as Nexium and some cholesterol medications including Lipitor, atorvastatin one of the statin drugs. There are a lot of drugs that impact thyroid hormone absorption – 565 to be specific! 5279 generic and brand names of these 565 drugs are known to interact with levothyroxine.

So if you are taking any kind of drug, please check with your pharmacist regarding the best timing for taking the thyroid hormone. Although no formal research has found an interaction between strontium and levothyroxine, it only makes sense that there would be one because strontium and calcium require the same pathways for absorption. So avoid taking your thyroid medication as the same time as your strontium or your calcium or any other supplement or medication or food. Hope this has been helpful.

Thanks for the great question, bye!
