Chromium picolinate is a nutritional supplement combining the essential mineral chromium with picolinic acid to enhance absorption. It is proposed to support healthspan by potentiating insulin action, thereby improving glucose disposal and metabolic function. However, its clinical efficacy in healthy, non-deficient individuals remains a subject of debate, with studies showing mixed and often modest results.
Verdict
Likely unnecessary for healthy individuals; potential minor benefit for insulin resistance.
