Chromium is an essential trace mineral that may enhance the action of insulin, a hormone critical for metabolizing and storing carbohydrates, fat, and protein. By potentially improving insulin sensitivity, chromium polynicotinate is proposed to support stable blood glucose levels, which is a key factor in preventing age-related metabolic decline.
Verdict
Potentially useful for insulin resistance, but limited evidence for general healthspan.

Protocol
- Typical doses range from 200 to 1000 micrograms (mcg) per day, often taken with meals to improve absorption.
Flags
- High doses (>1000 mcg/day) have been linked to rare cases of kidney damage.
- May interact with diabetes medications (e.g., insulin, metformin), requiring dose adjustments.
- Individuals with pre-existing kidney or liver disease should consult a physician before use.
