Like many doctors, I thought if we ate the right foods we wouldn't need any of that, but after hearing so much about it, I decided to investigate the subject for myself. I have been reading the available medical literature for quite some time. After my own research, I decided it was time for my family and I to begin a serious nutritional program, and that's what we have been doing for a couple of years. Studies from the National Cancer Institute, Harvard Medical School, U.S. Department of Health, and Johns Hopkins University concluded that nutritional supplementation produce positive changes in a person's health. Unless you are very familiarized with the latest studies you have no way of knowing.
People end up buying from the lowest bidder thinking they are protecting their health.
They don't think about the ingredients, the formulation, the manufacturing, etc. Remember, poorly manufactured, incomplete, and unbalanced nutritional products are a waste of money and do little to promote better health. My research led me to conclude that there are only a few companies manufacturing reliable nutritional products nowadays. We chose the one we think is the best of all.
