Chromium

A trace mineral that helps insulin do its job. Some studies show a modest benefit for blood sugar, while others show little effect.

Commonly used for

  • Blood sugar support
  • Insulin resistance
  • Sugar cravings (limited evidence)
  • PCOS with insulin resistance (limited evidence)

Found naturally in

  • Broccoli
  • Whole grains
  • Green beans
  • Potatoes
  • Brewer's yeast

Label red flags

  • Chromium stacked across a multi, a blood sugar formula, and a weight-loss product
  • Weight-loss claims, which are not well supported

Check with a provider

  • Taking insulin or diabetes medicine. Chromium may add to the blood-sugar-lowering effect, so watch for lows.
  • Taking levothyroxine. Chromium may reduce absorption, so separate doses by several hours.
  • Kidney or liver disease
  • Pregnancy and breastfeeding beyond the amount in a prenatal
