Overdosing on Vitamins?
Wouldbe posted:
Some doctors suggest taking vitamin supplements but others say too many vitamins can be toxic. What is the danger from too many vitamins? Can they cause heart attacks?
katurnbow responded:
Check out this site to evaluate supplements: it is a small fee but it they do 3rd party evaluations on supplements which is important because you really may not know all of the ingredients in the medication. But the companies that operate on a certain standard embrace transparency.

Another great place to find information is on:

"Can they cause heart attacks?"

Anything medical is seemingly possible today, though you first have to understand that a heart attack (myocardial infarction, MI, actual death or necrosis of heart muscle tissue/cells) is caused by a coronory artery becoming 100% blocked (occluded), typically by way of plaque build-up or sudden rupture, or even a blood clot formation (thrombus/thrombosis), or say, prolonged or extended-duration of coronary artery spasm.

Best of luck down the road of life.

James Beckerman, MD, FACC responded:
I believe that we should think of supplements like medications and use the same standards when considering to take them. Safety and effectiveness need to be supported by scientific studies.

In general, reasonable doses of most vitamins are considered to be safe, although many physicians believe that their effectiveness in preventing disease has been overblown by the media and by those with a financial incentive to sell them. For example, there is data that suggests that vitamin E supplements could be associated with an increased risk of heart disease.

Thank you.

Thank you.
katurnbow replied to James Beckerman, MD, FACC's response:
Dr. one of things I found is that Europe covers certain supplements under their insurance laws and I have read clinical studies associated with effectiveness.

Y does it seem that American companies are not willing to put the backing behind these supplements that obviously work. The type of clinical studies that are needed to justify a lot of the skepticism cost millions. Being a form pharm rep it seems to come back down to if Big business can't make a buck then they will discredit it.

Lastly, Do you know personally of any cases where someone over dosed on supplements/vitamins?
