Chromium (Picolinate)
Also known as: Chromium picolinate · Chromium polynicotinate · Trivalent chromium
A trace mineral that potentiates insulin signalling. Evidence for blood glucose reduction is moderate; body composition claims are not well supported in non-deficient individuals.

What Is Chromium (Picolinate)?
Chromium potentiates insulin action by binding chromodulin (an oligopeptide in insulin-responsive cells), which activates the insulin receptor tyrosine kinase and amplifies the intracellular signalling cascade. It is found in brewer's yeast, whole grains, and meats.
How It Works: The Science
After insulin binds its receptor, chromium-activated chromodulin further stimulates the insulin receptor kinase domain, amplifying GLUT4 translocation to the cell membrane and glucose uptake. Chromium picolinate enters cells more efficiently than inorganic chromate, explaining its superior bioavailability.
Primary Mechanism
Insulin receptor sensitisation via chromodulin binding
Evidence-Based Benefits
Dosage Guide
Effective Dose
200–1000mcg / day
200–1000mcg/day chromium picolinate. Effects most pronounced in those with insulin resistance or deficiency. Well-nourished individuals without blood sugar issues will see little benefit.
Safety Profile & Side Effects
Generally safe at recommended doses. Chromium picolinate generates oxidative DNA damage in cell studies — significance at human doses unclear. Stay within the AI (35mcg/day for men, 25mcg for women) unless targeting therapeutic effects.
Who Should (and Shouldn't) Take It
Individuals with insulin resistance, pre-diabetes, or type 2 diabetes (as an adjunct to medical treatment). Limited benefit for healthy athletes.
