It is generally accepted, that certain supplements can play a critical role in our health. Unfortunately, however; many settle for the guidance of those that; are trying to make a sale, and who have little or no expertise in this area. There are some supplements out there that can be very beneficial, but I suggest that you put in a little research before starting a regimen.
I am a heart attack survivor. At a certain point, my doctor told me about the possible benefits of taking Omega 3 fish oil, and CoQ10; and he steered me toward a product that is sold at a particular website. I saw the same product advertised at another doctor's office, and I assume there is some kind of financial incentive for doctors to refer patients to that particular product. I'm not saying there is anything wrong with that, but I believed it was in my best interest to do some research to help me make some good decisions.
I first used www.NaturalDatabase.com, to look at what their studies have concluded as to the need for the supplements my doctor spoke of, in treating my conditions; and then I consulted www.ConsumerLabs.com, to see the research on specific brands of those supplements. Neither site is free to use, but both have very affordable memberships. www.NaturalStandard.com is very similar to "Natural Database". I was able to gain temporary access, and I highly recommend it; but because I felt I had enough information already, I decided not to put out the additional money to purchase their membership.
As part of my research, I spoke to a representative from the company my doctor referred me to. The website features some very important info, and the representatives help educate you as well. When I asked a representative to refer me to any independent studies that evaluated the effectiveness of their product, she told me that she wasn't aware of any such studies!
During my research, I also didn't find any useful info on their product, but I did find a very highly regarded manufacturer of supplements that has been around for a long time, Tishcon. If you are going to take suppliments you may want to consider their products.
