Chromium Picolinate

Reviewed by the Nimbera editorial team · Last updated May 2026

Zhao et al. 2018 systematic review (Nutrients, PMID 28677892) - 28 RCTs found chromium supplementation (200-1,000 mcg/day) significantly reduced fasting glucose (WMD -0.84 mmol/L) and HbA1c in type 2 diabetes patients. Effects were more pronounced in individuals with more significant baseline insulin resistance.$5-$15/month.

How to use

Take 200-1,000 mcg/day of chromium picolinate or chromium polynicotinate (better absorbed forms) with food. Lower doses (200 mcg/day) for general insulin sensitivity support; higher doses used in clinical diabetes research. Chromium is also found in brewer's yeast, whole grains, broccoli, and green beans.

How it works

Chromium is an essential trace mineral that potentiates insulin action by facilitating the binding of insulin to its receptor and enhancing downstream signalling (PI3K-Akt pathway, GLUT4 translocation). Low chromium status impairs glucose tolerance; supplementation restores normal insulin receptor sensitivity, particularly in tissues with high glucose demand (muscle, liver).

Where to buy

NOW Foods Chromium Picolinate ($5-$10/250 capsules), Jarrow Formulas Chromium GTF ($8-$12/100 tablets), Thorne Chromium Polynicotinate ($15-$20/60 capsules) - widely available at pharmacies and health food stores.

Typical cost: $5-$15/month.

Safety notes

Monitor blood glucose carefully if on insulin or diabetes medications - chromium lowers blood sugar and can cause hypoglycemia in combination. Chromium picolinate at very high doses has theoretical DNA mutagenicity concerns in animal studies - stay within 200-1,000 mcg/day range and follow your doctor's guidance. Antacids and calcium carbonate reduce chromium absorption - space by 2 hours. Not a replacement for medical diabetes management.
