Jiaogulan and Insulin (rDNA)

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Insulin (rDNA)

Insulin (rDNA) falls under ANTIDIABETES DRUGS — the group Jiaogulan interacts with.

Theoretically, jiaogulan might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Clinical research shows that jiaogulan can lower 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 to keep in mind with this combo: jiaogulan may lower your blood sugar on its own. Some clinical research does back that up. So when you stack it on top of your insulin (Humalog, Humulin, and the like), the two can add together and push your sugar down further than you planned. That raises your odds of a low blood sugar episode, with symptoms like shakiness, sweating, dizziness, confusion, a racing heart, or feeling suddenly hungry.

Insulin works directly, it isn't a prodrug that needs activating, so this is simply about two blood-sugar-lowering effects piling up. The evidence here is moderate, not ironclad, but I'd take it seriously since lows can come on fast. Please don't change your insulin dose on your own. Check with your doctor or pharmacist first, and monitor your numbers closely if you start jiaogulan.
