Short answer

We found no documented interaction between Magnesium and Ashwagandha 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.

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

Ashwagandha

What it is: A plant root used in traditional Ayurvedic and Unani medicine, often called an adaptogen.

What the research says: Several small trials of 6 to 8 weeks found people felt less stress and anxiety, with doses around 500 to 600 mg a day working better than lower ones. A few small studies suggest a modest sleep benefit. It has not been studied thoroughly.

Cautions

• Well tolerated for up to about 3 months; long-term safety isn't known.
• Mild side effects can include upset stomach, loose stools, nausea and drowsiness.
• It has been linked to liver injury in some people.
• Not for people who are pregnant or breastfeeding, or who have prostate cancer.

Medicines to check

• Thyroid medicine (ashwagandha may affect how the thyroid works)
• Diabetes and blood-pressure medicines
• Sedatives
• Medicines that suppress the immune system
