Our Advisors

Medtrition Clinical Advisory Board. We recognize that optimal nutritional management should be a combined clinical effort. Therefore, we have established a clinical advisory board (CAB) consisting of Key Opinion Leaders (KOL) to assist us in our approach. Based on the clinical background and nutritional expertise of our CAB members, each member provides a perspective of how nutrition intervention, and their clinical role in the healthcare system, play a part in patient care. Both teams share a common value of nutritional care as a necessary modality of intervention for the health and well-being of all.

We are honored to have these KOLs as part of our advisory team. Please take a moment to learn more about our CAB members and their impressive backgrounds in the world of clinical nutrition and medicine.
