Dear friends. My name is Dr. Luis Ruano, a practicing Chiropractor. I have been using some 14-15 different supplements from Lifesource for several years. I can positively say they are some of the best in the industry. Not only do I support that they are a Christian based company, have great staff working for them but again the outcome for my patients from the array and diversity of nutritional supplements has been bar non, some of the best. I would highly recommend any doctor that is interesting in keeping their patients well, to look into adding Lifesource to their office.
