All are listed by their chemical formula. These are very important factors when choosing a supplement. When the chemical formula is listed, you can be sure it is going to help you. For example, I have included the chemical formula for Omega-3 fatty acids, the most important fatty acids, in the "Recommended Supplement Dosage." Most people who choose to use these supplements are not looking for the exact chemical formula, but it is good to know.
For a long time, I've used the term "dietary supplements" or "supplements" in place of "supplements." I have no problem with the term "supplements," but I think it should be used with caution when talking about foods. It is important to know what is in each and every food you eat. And most people, including me, don't have the ability to look up all the ingredients in the food they eat. It is better to say what a food does, or does not do, than to be totally ignorant of what is in the food they're eating. I also have a page on that subject, as well.
I'm not a doctor, but I am a medical doctor and have a pretty good reputation.
