Calcium supplements and cardiovascular disease: What’s the deal?

Posted on: August 14, 2013   by  John Cannell, MD


Professor Ian Reid of University of Auckland has recently published an excellent review on calcium supplementation and cardiovascular disease.

People are often worried about taking calcium because it’s commonly reported in the media that calcium supplements may increase your risk of cardiovascular disease. In addition, in his review, Dr Reid did find that many people are taking too much calcium, and it is damaging their cardiovascular system.

    You’ve written an excellent letter to the FNB/IOM, Dr. Cannell.

    And, I’m always grateful to see those knowledgeable vitamin d physicians and researchers support you. It is quite an impressive list of doctors.

    How I wish the playlist of these supporters might be extended…shall we say grown?

    I am disappointed, though not surprised, to see no Yale physicians/researchers on this list of supporters. 🙁

    I do know that there are physicians and researchers at University of Connecticut who are vitamin D Receptive (let us call them VDRs…lol).

    By the way, don’t you just love that quote by Goethe??

    “Knowing is not enough; we must apply. Willing is not enough; we must do.”

    I think this is a quote for US to live by…

    The issue of too much calcium and its relationship with cardiovascular disease may go away with the consideration of getting Vitamin K2 back into our diets. It seems that Vitamin K2 helps calcium to our bones. An excellent discussion on Vitamin K2 can be found is a book by Dr. Kate Rheaume-Bleue “Vitamin K2 and the Calcium Paradox- How a Little-Known Vitamin Could Save Your Life”. Also check out Dr Kate on a YouTube search for her other discussions. Look for Vitamin K2 in the MK-7 form. I also look for food sources of K2 and they can be found in eggs in free range chickens that only eat grass. I occasionally take in Brie which is also a good dietary source of K2. Of course more research is needed with the Vitamin K2 and its relationship with our health, but it looks promising at this time.

    I just got a new book by Fred A. Kummerow, Ph.D. (2014-02-18). Cholesterol is Not the Culprit: A Guide to Preventing Heart Disease (Kindle Location 5). Spacedoc Media, LLC. Kindle Edition.

    Fred will have his 100th birthday this year. He has researched lipids for 70 years and has lots of good info on how cholesterol in not bad etc. But he seems decades behind on his vit D knowledge and says we get TOO MUCH vit D and it is causing atherosclerosis because it causes calcium to circulate and it has to go somewhere- the blood vessels. He only has few references. Comments?
