Since becoming a member of BUSM in 1987, Holick provides initiated several successful clinical analysis applications. He helped pioneer the assays for supplement D and its own metabolites which are utilized world-wide to determine a patient’s vitamin D position and to assess disorders of calcium and bone fat burning capacity.
