This is anecdotal, and there isn't strong clinical evidence that it works for everyone.

What is it? / Overview

Chromium enhances insulin signaling and plays a role in carbohydrate metabolism. Although supplementation may produce small improvements in blood glucose in some people with type 2 diabetes, evidence is inconsistent and it is not recommended as a primary diabetes treatment.

How is it used? / Administration

Form: Chromium picolinate (most studied); chromium nicotinate alternative

Typical dose studied: 200–1,000 mcg/day (200–400 mcg/day most commonly studied)

Timing: With meals

True chromium deficiency is rare. Routine supplementation for weight loss or bodybuilding is NOT supported by current evidence.

How well does it work? / Evidence

? Emerging / limited evidence
