“Your body was built to heal. We help it remember how.”
— Drs. Mark & Michele Sherwood, Functional Medical Institute
Why we put our name on this
We're Pat & Karen Schatzline — evangelists, authors, and speakers who have spent the last decade helping hundreds of thousands of people take back their health. We've seen the supplement fads, the miracle powders, and the wild-west peptide market — and we wouldn't point you toward any of it.
Vitality Kingdom Labs exists for one reason: to connect the people we love to the medical team we personally use and trust. Drs. Mark & Michele Sherwood at Functional Medical Institute do it right — comprehensive blood panels (not a single page of “normal”), third-party tested peptides with certificates of analysis, bioidentical hormones, and a plan built from your results, not a template.
This is the team we trust with our own health — and the one we recommend from every stage we stand on.
