istock photo of calcium supplements 300x203 Death by Calcium, why Calcium Supplements Increase Heart Attacks   Ron Rosedale, M.D. interviewed by Shelley Schlender, KGNU This is an interview with Shelley Schlender, KGNU radio, Boulder, Colorado. Thank you Shelley for the article, graphics and the interview below. You can learn more about Shelley and her passion for exposing the truth in health at her website, www.meandmydiabetes.com

New research published in the British Medical Journal indicates men and women over 40 who take calcium supplements increase their risk of heart attack by 30%, compared to people who don’t take the supplements.  The study points out that often, people take calcium supplements hoping that this will reduce their risk of breaking bones,  even though in actual fact, taking more calcium only reduces bone fractures by a marginal amount.  Baron and coauthors caution that the benefit of reducing bone fracture risk by taking calcium supplements may be outweighed by the likelihood of increasing heart attacks.

The study is being hotly contested by many supplement manufacturers.  One person who says it’s a predictable result is Dr. Ron Rosedale, who has been speaking out against calcium supplements for years.  Dr. Rosedale points out that often, people who have “thin bones” have high amounts of calcium plaque in their blood vessels, a condition which is well-documented for increasing the chance of heart attacks.  People with thin bones also can have calcium deposits in their joints . . .  for instance, with arthritis.  Dr. Rosedale says that when people have osteoporosis, it’s generally not the case that they need more calcium.  Instead, they need clearer signaling instructions in their body, so the calcium goes where it’s needed, not stuck in places that cause trouble.  For more, here’s Dr. Rosedale.

    How then can you take out the extra calcium deposit out from your system? Is there a cleansing agent or supplement to eradicate the calcium deposit?

    • Posted November 26, 2011 at 4:21 pm | Permalink

      The short answer is no, and not even chelation therapy, though it may have other beneficial effects. Magnesium can help counter calcium within cells. However, long term just following The Rosedale Diet, seems to lower calcium deposits, perhaps by increasing mechanisms of repairs and regeneration.

    Not sure if overactive immune system or lack of social contact.

    Should children take calcium supplements or will a healthy diet high in a variety of vegetables suffice? I think my children eat a fair amount of vegetables compared to your average american kid but my wife insists on giving supplements to my them because our pediatrician recommends it.

      Your children will be much healthier without calcium supplements.

      Most of the comments here are spam comments, that is why. Dr. Ron Rosedale should probably install some kind of spam filter like Akismet on his blog.

    Fascinating concept about instructions and miscommunications.
    1. Do you know what is it about your diet that may assist bone repairs and regeneration?
    2. You mention progesterone and testosterone as a positive means to use.
    Interested in knowing how do you test the role hormone imbalance may play in this dance?
    In other words, is depleted or hormone imbalance the primary cause you are aware of for excess calcium building up?
    3. Is there a role for silica in this process?

      Leptin plays a huge role in bone growth, apparently through central (brain) mechanisms, perhaps via the vagus nerve. Also, leptin and insulin regulate whether you can burn fat or not. If you cannot burn fat, then even if you do not eat you must burn glucose. Since the body stores very little glucose, and prefers to save what it has for anaerobic emergencies, if one must constantly burn glucose for instance while sleeping, it will be generated by the breakdown of lean tissue such as the protein framework of bone. Being able to consistently burn fat spares this necessity. It is also important to note that the strength of bone is determined by the protein matrix, not the mineralization. Please go to the main website and blog and listen to/read interviews with me about calcium and bone that are posted. Thanks for the fine questions.

      There are a couple of transcripts of interviews I’ve given pertaining to calcium and bone that are in the archives of this blog and my website. I hope you will read them as they will answer your questions. Thanks for the comment.

    Doctor.

    It seems that bone density is always treated with adding more calcium. It takes more than bricks to build a house, it also takes mortar. In our bones, there is protein (collagen) matrix that binds the minerals into bone.

    Why is this side of the equation never addressed? The aminos needed for collagen are certainly much less abundant in our typical diet today…

    I´d like to add that regarding the cardiovascular safety of calcium and vitamin D, Bolland´s paper specifically excluded studies of calcium and vitamin D from their analysis. Indeed another recent meta analysis has not been able to find any evidence of increased cardiovascular risk with calcium and vitamin D supplementation (www.ncbi.nlm.nih.gov/…/20194238). The data of this meta analysis suggests that vitamin D supplements at moderate to high doses may reduce CVD risk, whereas calcium supplements seem to have minimal cardiovascular effects.
    It might be also interesting to note that in their discussion of the potential underlying mechanisms by which calcium supplementation might increase cardiovascular risk, Bolland et al. mention various factors relevant to regulation of vascular calcification, but do not include vitamin K status amongst these factors.

    You can read more in my comments „STONE TO DEATH FALLACY“
    (http://www.greenmedinfo.com/blog/turned-stone-calcium-pills-proven-once-again-kill)

    I´d also like to add that according to S. Boyd Eaton there is evolutionary evidence that humans evolved in a calcium rich environment before the advent of farming 10 000 years ago.( http://ajcn.nutrition.org/content/54/1/281S.long). It´s also interesting to note that none of the terrestrial land based vertebrates maintain their vitamin D status from a nutritional source.

    In fact, few renal stones are associated with early skeletal remains, yet the consumption of calcium by early humans was three to five times that of people in modern industrialised countries, where up to 10% of men and 3% of women have renal stones at some time in their life. Moreover, a major prospective study by Curhan et al in North America showed in a cohort of 45 000 men that the risk of symptomatic stone disease was less for those with higher dietary calcium. It has been shown that increased oral calcium but not vitamin D in association with a reduction of the relative proportion absorbed, may be pertinent to the prevention of calcium oxalate rich stones.

    Other studies showed that people with hypercalciuria have higher sensitivity of vitamin D receptors. Indeed, oral intak of vitamin D is associated not only with hypercalciuria, but also with increased cardiovascular risk. Thus it seems that not calcium, but other nutritional factors, including vitamin D, vitamin K2 deficiency, may play role in increased CV risk observed in this study. In this regard, it´s also worth mention that none of the terrestrial land based vertebrates maintain their vitamin D status from a nutritional source.

    Very interesting information and something I have often wondered about. When I was young child my family ate very little dairy. We ate a very healthy diet of home grown vegetables, eggs, and chicken. We ate very little sugar or junk food until I was about 13 or 14. The one bad thing about our diet was the so called healthy whole grain wheat bread ( think the whole wheat is what caused my horrible cramping when using the restroom as a young child, which as a child I thought was normal) that my mother baked nearly every day for us and potatoes and rice. I think we did also lack some essential fats except perhaps what we got from the eggs, chicken and occasional beef that we ate We almost never ate sea food except occasional canned tuna. We also spent many long hours playing outside in the sun, climbing trees, running and jumping. Great for building bones! Sadly, after that point our lifestyles changed a great deal and my family adopted the SAD and a more sedentary lifestyle. As a result we have all suffered and consequently my younger siblings that were raised on the SAD have had many more health problems than I have. I actually look nearly the same age or younger than some of my siblings that are 9+ years younger than me. I do credit some of that to the supplements I’ve taken religiously since I was seventeen.(multivitamins and chelated minerals)

    Despite the small amount of dairy as a young child, when I had my bone density tested in my early twenties they were found to be literally off the charts for bone density. I’ve always assumed this was good thing but I am now wondering if it is. I have had chronic pain and inflammation and weight problems since my early twenties. I also at one point had a strange bony protrusions on the inside of my wrists that would build up over a couple of months and then one morning would be gone. They were very hard when pushed on, like bone. Every time I thought I really need to get this checked out they would be gone. I was also raised in the we don’t go to the doctor unless we’re dying camp. I believe it had something to do with the tedious work that I was doing as a baker and the repetitive stress that it was putting on the tendons on the inside of my wrists. It was very painful at times and when I woke up most mornings I could barely move my hands until I got them warmed up through movement. The bone spurs stopped occurring when I quit that job but my wrists are still a little larger than they were before, though not oddly shaped. I’ve often wondered if the chronic pain I’ve had in other areas is from similar build up of calcium deposits in my joints and other strange places. Come to think of it I wonder if the so called growing pains I suffered from as a child may be related.

    I’m just desperate to find an an answer to my pain problems and stop living on OTC pain meds and the occasional prescriptions from doctors who can never help me get to the bottom of my multiple issues. I have opted to suffer more often lately rather than take them since I’m breastfeeding my 51/2 month old. I’ve also suffered from lifelong anxiety and depression problems and think this also has something to with my diet and possibly heavy metal exposure from amalgams, etc.

    Is this all a product of deranged mineral and glucose metabolism as I have thought? What can I do about it?

    By the way I rarely ever comment on any of the sites I have been obsessively reading but after the posts that I’ve read here and the way you have linked other information I have gathered I am hopeful that you can help point me in the right direction. I love your site. Thank you for caring enough to share!

    Any thoughts and suggestions would be most appreciated!

    What about algae calciums? I’m hoping they are ok. I am very dairy intolerant even from raw sources and can’t eat high oxalate foods such as spinach. Thanks so much.
