Chromium Safety & Side Effects
Our assessment
Based on FDA data, chromium from food and supplements does not appear to cause harm, though research is limited. The overall risk profile is low, but specific populations must exercise caution.
Safety profile
FDA received adverse event reports for chromium, though specific side effect counts are not detailed in the provided data. The data notes that harm is not typically observed, but the evidence base is limited FDA FAERS ↗.
How it works
Chromium is a trace mineral that may enhance insulin action. However, the primary safety concern involves drug interactions: taking chromium with insulin might cause low blood sugar levels, and it may also interfere with metformin and other antidiabetes medications FDA FAERS ↗ NIH DSLD ↗.
Our recommendation
People with kidney disease or liver disease should be cautious about taking high amounts of chromium. If you take insulin or antidiabetes medication, consult your healthcare provider before using chromium supplements, as they may lower blood sugar FDA FAERS ↗ NIH DSLD ↗.

Safety Overview
Chromium from food and dietary supplements does not appear to cause any harm, but research is limited. People with kidney disease or liver disease should be cautious about taking high amounts of chromium.
Drug Interactions
Yes. Chromium supplements might interact or interfere with medicines that you take. Here are a few examples: Insulin. Taking chromium together with insulin might cause low blood sugar levels. Metformin and other antidiabetes medications. If you take antidiabetes medicine, taking chromium dietary supplements might cause low blood sugar levels. Levothyroxine. Levothyroxine is a medication used to treat hypothyroidism (a condition in which the thyroid gland does not make enough thyroid hormone ). Taking chromium dietary supplements together with levothyroxine might reduce the amount of levothyroxine your body absorbs so you might not be getting the full effect of the medication. Tell your doctor, pharmacist , and other health care providers about any dietary supplements and prescription or over-the-counter medicines you take. They can tell you if these dietary supplements might interact with your medicines. They can also explain whether the medicines you take might interfere with how your body absorbs or uses chromium or other nutrients.
