Some are natural and some are synthetic. Some are beneficial and some are not. If you are looking for a specific supplement, then you have to know what you are getting into. I don't know what I am giving to my patients, and the FDA doesn't tell me. The only thing I can tell you is that there is no one magic pill. A good doctor will tell you the right supplements for you, based on your individual needs and your medical history. Please do some research, and then get your answers to the following questions:
What is this product made from? A: The ingredient that I use is a combination of algae extract, soy protein concentrate, and collagen that comes from the skin. What are the ingredients? A: There are a couple of things in it. The protein and collagen in it are mainly from algae, and they are not from soy. They are also not from animal source, and they are from 100% pure collagen. The other ingredients are a few amino acids and vitamins that are made from collagen from animals. What other uses are there for a dietary supplement? A: There are so many uses. You can have a whole bunch of benefits for your body.
