Soy and Glucagon

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIDIABETES DRUGS

Why this applies to Glucagon

Glucagon falls under ANTIDIABETES DRUGS — the group Soy interacts with.

Soy can lower blood glucose and have additive effects with antidiabetes drugs.
Clinical research shows that whole soy diets and soy-based meals reduce fasting glucose levels in diabetic and non-diabetic individuals. Also, individuals following a soy-based meal replacement plan seem to require lower doses of sulfonylureas and metformin to manage blood glucose levels when compared with individuals following a diet plan recommended by the American Diabetes Association.
Severity Moderate Likelihood Possible Evidence A

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's a little wrinkle worth knowing about. The interaction on file says soy can gently lower blood sugar, which could add to diabetes medicines. But glucagon does the opposite of most diabetes drugs. You use it as a rescue treatment when blood sugar drops dangerously low, and it works by telling your liver to dump stored sugar back into your blood to bring you back up.

So in a true emergency, eating soy foods isn't going to stop glucagon from doing its job. The bigger picture is simply that soy may nudge your everyday blood sugar a bit lower, which could make low-sugar episodes a touch more likely over time. If you rely on glucagon, it's worth mentioning your soy intake to your pharmacist or doctor so they can keep an eye on your overall control.

“If you keep glucagon (Baqsimi) on hand to rescue a severe low blood sugar, read this list with genuine care. Of the 256 supplements and herbs on file, 239 affect blood sugar control, most by lowering glucose further, which can set up the very crash glucagon exists to reverse.”

About Soy

What is Soy?

  • Menopause symptoms (hot flashes)
  • Heart and cholesterol health
  • Bone health
  • Plant-based protein source
  • General nutrition

Soy is a nutritious bean that is a staple food and a popular source of plant protein and isoflavones. Eating soy foods as part of a balanced diet is generally considered safe for most people, and there is moderate evidence it may modestly help cholesterol and some menopause symptoms, though results vary. Talk with your pharmacist or doctor before using concentrated soy isoflavone supplements, especially if you have a history of hormone-sensitive conditions.
