Docosahexaenoic Acid (dha) 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 Docosahexaenoic Acid (dha) interacts with.

Theoretically, taking DHA with antidiabetes drugs might reduce the effects of these medications.
In people with type 2 diabetes, including those taking oral hypoglycemic medications, DHA seems to increase fasting blood glucose levels.
Severity Moderate Likelihood Possible Evidence B

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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing about glucagon: it's actually the opposite of most diabetes medicines. Instead of lowering your blood sugar, it's an emergency rescue treatment that tells your liver to dump stored sugar into your blood to pull you out of a dangerous low. So the interaction we have on file, where DHA may slightly nudge fasting blood sugar upward, doesn't really work against glucagon. If anything, both push blood sugar in the same direction during an emergency.

The bigger picture: this DHA effect is based on weaker evidence and is fairly small, and it matters most for your daily, scheduled diabetes meds, not your rescue glucagon. Still, if you take DHA regularly, it's worth mentioning to your pharmacist or doctor so they can keep an eye on your numbers.
