I'm going to be the wet blanket is the discussion of the wonders of OTC supplements. The fact that you can buy it without a prescription doesn't mean that you are'nt putting a drug into your body and they are harmless.As one page put it "poison ivy is natural too". Ideally you would work with your doctor in the use of OTC supplements and hope he/she is educated enough or willing to do research about the benefits/risks of a particular supplement as it applies to you specifically as well as open mined enough to tell you to go for it as an alternative medicine if he feels it may benefit you. Magnesium isn't a harmless little supplement.It can interfer with tetracycline and and if you have kidney problems can lead to problems. Here is the med-line site for it: http://www.nlm.nih.gov/medlineplus/druginfo/magnesiumsupplementssystemic202644.html You may have to type it into your browser as it is an awfully long line. Then again you can just look up med-line itself. As far as Co-Q-10 goes a web search showed hundreds of sites that gave glowing reports and were willing to sell this awesome supplement "cheaper than the next site. Looking at the prices it really isn't so cheap considering I have a $5 co-pay on prescription drugs. Also as supplements aren't regulated do you really know what the fillers the manufacture may have put in with the star ingrediant? There is very little scientific research that backs up the hype of Co-q-10,maybe because there hasn't been a lot of research done on it http://www.fciheart.com/CoEQ10.html It may turn out to be the next asprin for all I know. What little I did find in medical research seemed to be supportive of it as well but always with the side-bar that not enough research has been done on Co-q-10 and drug interactions as well as adverse affects on certain disease. Till then I personally will hold off using it. Joanne _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp
