Mineral

Chromium (as Chromium Chloride)

Also known as: Chromium, Chromium Chloride, Trivalent Chromium, Cr

B
Evidence

Chromium is a trace mineral that enhances insulin action and glucose metabolism as part of the glucose tolerance factor (GTF). It plays a supportive role in macronutrient metabolism and blood sugar regulation.

Primary uses

  • Enhances insulin sensitivity and glucose tolerance
  • Supports carbohydrate and lipid metabolism
  • May help stabilize blood sugar levels
  • Cofactor in glucose homeostasis

How it works

  • Potentiates insulin receptor signaling and glucose uptake
  • Component of glucose tolerance factor (GTF) with niacin and amino acids
  • Enhances GLUT4 translocation to cell membrane

Dosage

Typical range
50–200 mcg daily
Timing
With meals containing carbohydrates
With food
Recommended; enhances absorption and optimizes glucose metabolism context
Duration
Studies show effects develop over weeks to months; long-term safety is generally good at recommended doses
Special populations
Caution in patients with renal impairment; those with insulin-dependent diabetes should monitor glucose under medical supervision

Forms

  • Chromium chloride· 70/100
  • Chromium picolinate· 70/100
  • Chromium polynicotinate· 70/100

Safety

Common side effects

  • Generally well-tolerated at recommended doses
  • Rare: headache, insomnia, or mood changes reported at higher doses

Contraindications

  • Severe renal impairment (chromium is renally cleared)
  • Concurrent use of corticosteroids (which increase chromium excretion and may reduce efficacy)

Evidence notes

Chromium has solid mechanistic support and several RCTs demonstrating modest effects on glucose control and insulin sensitivity, though effect sizes are inconsistent. Evidence for healthy individuals is weaker than for those with dysglycemia.

Grade B: Some human trials support key claims; further confirmation needed.
