Short answer

We found no documented interaction between Chromium and Magnesium in the sources below. That isn't proof the combination is right for you: check each one's cautions, and ask your pharmacist if you take medication.

Chromium

What it is: A mineral found in many foods that may help the body use carbohydrates, fats and protein.

What the research says: Studies on blood sugar are mixed. The American Diabetes Association doesn't recommend it because it has no clear benefit.

Cautions

• No harm has been shown, but research is limited. People with kidney or liver disease should be careful with high amounts.

Medicines to check

• Insulin, metformin and other diabetes medicines: chromium may push blood sugar too low
• Levothyroxine (thyroid medicine): chromium may reduce how much is absorbed

In Holitro: Chromium (1000 mcg per capsule)

Magnesium

What it is: An essential mineral the body uses for muscle and nerve function, blood sugar and blood pressure control, and making protein, bone and DNA.

What the research says: Supplements may lower blood pressure slightly. People who get more magnesium from food tend to have a lower risk of type 2 diabetes, and it matters for bone health.

Cautions

• Adults shouldn't take more than 350 mg a day from supplements unless a clinician advises it.
• Too much from supplements can cause diarrhea, nausea and stomach cramps.

Medicines to check

• Osteoporosis medicines (bisphosphonates) and some antibiotics: take them apart from magnesium
• Diuretics
• Long-term acid-reflux or ulcer medicines can lower magnesium levels

In Holitro: Magnesium Glycinate (133 mg per capsule)
