Health Experts Issue New Warning About Magnesium Supplements — Especially for These Two High-Risk Groups

Tip: Blood pressure should be monitored carefully if magnesium is taken alongside these medications.

Gabapentin

Gabapentin, often prescribed for nerve pain or seizures, may be less effectively absorbed when taken with magnesium.

Tip: Taking magnesium and gabapentin at different times of the day may help avoid this interaction.

Levothyroxine (Thyroid Medication)

Magnesium can interfere with the absorption of thyroid medications such as levothyroxine.

Tip: Levothyroxine should usually be taken on an empty stomach, and magnesium should be taken several hours later.
