Dr. Carl has been a chiropractor since 2000. He has been studying the effects of food and products on the body for over 21 years. Through his research he has confirmed what he always preaches. What we put in or on our bodies is of greatest input on our health outcomes. Through research and experience using products on his own family as well as with patients, he has compiled a vast list of ingredients that he will never use... and others that he will recommend for all. His knowledge of natural remedies and the potential dangers of medicines and synthetics have turned him very "crunchy" over the years.
