Additional Information

Licensed and highly experienced Medical Doctor (MD) I've consulted well over 150,000 patients in my career. I've observed the critical role that diet plays in health, wellness & recovery. I'm not some formulator touting the latest foods in wellness or some guru blindly promoting the wild and unrestrained use of nutritional products without evidence of therapeutic benefit. My clinical experience in countless inpatient and outpatient healthcare scenario's has demonstrated that the application of specific combinations of diet, vitamins, minerals, superfoods and select phytonutrients can result in synergistic enhancements, where the whole is far greater than the sum of it's parts. Every formula I have is borne out of my considerable clinical nutrition research, observation, testing & experience in a healthcare setting. Mega-dose Vitamin C was a significant part of my clinical practice in the Philippines for over 16 years. I hope you enjoy it. Dr. Farrah
