Safety at a glance
This score comes from an AI-written analysis of the pair. Our interaction rules check it and can only make it stricter, never milder. Informational only: it can't account for your medications, conditions, or genetics.
What the AI-written analysis says
Chromium is a dietary supplement that may have potential benefits for glucose metabolism, while Metformin is a prescription medication primarily used to manage blood sugar levels in individuals with type 2 diabetes. There is limited evidence on the safety and efficacy of combining Chromium with Metformin, and caution is advised due to potential interactions affecting absorption and overall effectiveness.
Metformin is a prescription medication. This page describes publicly documented interactions — it can't see your dose, your other prescriptions, or your labs. Discuss any supplement with the prescriber or pharmacist who manages this medication before combining.
Known interactions
Chromium may theoretically affect the absorption and effectiveness of Metformin. No timing arrangement makes this combination safe — see the warnings above.
Chromium
From the AI-written analysis.
Generally considered safe when taken in appropriate doses; however, long-term safety is not well established.
Typical dosage: Varies by product — follow the label.
- Gastrointestinal upset
- Headaches
- Skin reactions (rare)
- Consult healthcare provider before use, especially if you have kidney or liver issues.
- Monitor blood sugar levels closely when combining with diabetes medications.
Metformin
From the AI-written analysis.
Generally safe when prescribed; however, it can affect vitamin B12 absorption and is contraindicated in individuals with significant kidney or liver disease.
Typical dosage: As prescribed or as directed on the label
- Gastrointestinal issues (nausea, diarrhea)
- Vitamin B12 deficiency (with long-term use)
- Contraindicated in patients with severe kidney or liver disease.
- Monitor for signs of lactic acidosis, especially in those with renal impairment.
Timing
No timing arrangement makes this combination safe — see the warnings above.
Watch out for
- Berberine, gymnema, chromium, alpha-lipoic acid, bitter melon, fenugreek, and cinnamon extract each have documented glucose-lowering activity. Added on top of a diabetes medication the effects can stack, and blood sugar can drop lower than the medication alone would take it — the risk is highest alongside insulin or a sulfonylurea (such as glipizide, glyburide, or glimepiride). Low blood sugar can show up as shakiness, sweating, confusion, or a racing heartbeat. Tell the prescriber or pharmacist who manages the diabetes medication before adding any of these so glucose monitoring can be planned, and do not change the medication on your own.
