Chromium Pic · Chromium
Chromium Picolinate is a chromium(III) salt of picolinic acid commonly used as a dietary supplement for blood glucose support, insulin sensitivity, and body composition. Chromium is a trace mineral found in broccoli, grape juice, brewer's yeast, mussels, oysters, beef, eggs, and whole grains. Trivalent chromium (Cr+3) is the form found in food and supplements; hexavalent chromium (Cr+6) is the toxic industrial form (entirely different compound).,Chromium picolinate is the most-studied supplemental form, with picolinic acid serving as a chromium chelator improving bioavailability over chromium chloride or chromium nicotinate. Clinical evidence is most robust for type 2 diabetes (modest HbA1c reduction in some populations), polycystic ovarian syndrome (insulin sensitivity), and atypical depression (small effect on mood). Body composition / weight loss claims have been popular but not well-supported by rigorous trials. Standard supplemental doses range from 200-1000mcg/day.
Take with meals containing carbohydrates for best insulin-supporting effect. Start at 200mcg/day; therapeutic doses for T2DM are 600-1000mcg/day.
Start here. Every protocol below is ordered lowest-first. Begin at the smallest effective dose, hold about a week to assess tolerance, and step up only if needed.
How it works
Chromium's primary mechanism involves enhancement of insulin signaling at multiple steps. Chromium binds to a low-molecular-weight chromium-binding substance (LMWCr, also called chromodulin) which augments insulin receptor tyrosine kinase activity, increasing insulin signal transduction. The end result is improved cellular glucose uptake at lower insulin levels - effectively increasing insulin sensitivity.,Chromium also affects multiple downstream pathways: GLUT4 glucose transporter translocation to cell membranes (increases glucose uptake into muscle and adipose tissue), AMP-activated protein kinase (AMPK) modulation, and lipid metabolism through effects on PPAR-gamma. The combined effects support glucose homeostasis and may modestly improve lipid markers.,The mechanism for atypical depression effects is unclear but may involve serotonin pathway modulation and improved insulin signaling in brain (insulin resistance is associated with mood disorders). Body composition effects, where present, appear small and inconsistent in rigorous trials.
