How does chromium influence insulin action?

• A. It antagonizes insulin action
• B. It potentiates insulin action
• C. It inhibits insulin secretion
• D. It has no role in insulin action

Answer: (B)

Chromium helps insulin work more effectively, acting to improve insulin sensitivity. It’s thought to enhance insulin signaling at the cellular level, which boosts the ability of insulin to promote glucose uptake into muscle and fat tissues. Mechanistically, chromium may increase insulin receptor activity and support downstream signaling that stimulates GLUT4 to move to the cell membrane, allowing more glucose to enter cells. Because of this, chromium can help lower blood glucose levels with insulin present, or improve glucose utilization when insulin action is less than optimal. It does not block or reverse insulin action, so it does not antagonize insulin. It also does not primarily inhibit insulin secretion. And while the strength of clinical evidence varies, there is a rationale for chromium having a role in modulating insulin action, rather than having no effect.
