Let’s talk about something most of us overlook — simply because we don’t realize how important it is: MAGNESIUM

This essential mineral plays a key role in hundreds of enzymatic reactions in the body, affecting everything from energy levels and digestion to mood and sleep. Many people are unknowingly low in magnesium due to high stress levels, diets high in processed foods, and the daily use of common medications like pantoprazole (for acid reflux), or GLP-1 medications like Ozempic or Mounjaro — which can slow digestion and contribute to constipation.

I often hear people say they’re “on magnesium,” but when I ask what kind, they have no idea — and that’s super important because there are multiple forms of magnesium, and each has its own unique benefit. 

Magnesium Types & What They’re Good For

Type of Magnesium — Best For

• Magnesium Citrate: Occasional constipation

• Magnesium Oxide: Relieves constipation, supports bowel regularity

• Magnesium Glycinate: Calming, helps with anxiety and sleep

• Magnesium Malate: Energy production, muscle soreness

• Magnesium Threonate: Cognitive health, brain fog

• Magnesium Chloride: Cellular hydration, topical use

• Magnesium Sulfate: Muscle relaxation via baths

Why I Recommend It as an Obesity Specialist

As an obesity specialist prescribing GLP-1 medications, magnesium has become a go-to supplement in my practice. Many of my patients experience slowed gut motility, which leads to severe constipation.

While hydration and fiber (hello, apples with the skin on!) can help, sometimes your body needs more support — and that’s where targeted magnesium like oxide or citrate comes in.

A Real Story from My Clinic

Let’s talk about a real case from EMDI Health. We’ll call the patient Sarah.

In her first month on a GLP-1, she was doing well. But once we increased her dose to 5 mg, she began experiencing constipation — which I define as not having a daily bowel movement, straining, or passing goat pellet–like stool.

My first recommendation was to increase water intake and fiber — which she did. But even with that, her bowel movements remained irregular. That week, she actually gained a pound.

I then recommended magnesium oxide while continuing her increased water and fiber — and like magic, the constipation resolved. That week, she lost a whopping 7 pounds. Of course, I reminded her this wasn’t all true weight loss — since she was so backed up the week prior.
