Women-owned and LGBTQ+-affirming, Jennifer Black, MD in Encinitas holds dual board certification from the American Board of Internal Medicine and the American Board of Integrative Medicine on North El Camino Real. Her functional nutrition protocols for metabolic syndrome, diabetes reversal, and cardiovascular risk reduction share a root-cause methodology with Encinitas nutrition practices like Nurture & Flow Nutrition. A 2000 graduate of the University of Wisconsin School of Medicine who completed her internal medicine residency at UW Hospitals, she later conducted postdoctoral research at UC San Diego's Jamieson Lab in regenerative medicine and stem cell biology. She additionally holds subspecialty certification in obesity medicine and delivers consultations in Spanish and Tagalog for North County's multilingual patient base. Her integrative approach to chronic disease reversal through evidence-based pharmaceutical tapering operates within the same functional medicine philosophy practiced at Terrain Family Medicine, though her protocols are guided by lab-verified biomarker panels. Highest-complexity cases involve multi-system metabolic workups integrating lipid subfraction analysis, inflammatory markers, and hormonal assays to design individualized disease-reversal protocols.
