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

Moderate

ANTIDIABETES DRUGS

Why this applies to Insulin Glulisine (rDNA)

Insulin Glulisine (rDNA) falls under ANTIDIABETES DRUGS — the group Maritime Pine interacts with.

Theoretically, maritime pine bark extract might increase the risk of hypoglycemia when used with antidiabetes drugs.
One clinical study shows that maritime pine bark extract decreases blood sugar in patients with diabetes being treated with antidiabetes agents. Monitor blood glucose levels closely. Dose adjustments might be necessary.
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

Apidra (insulin glulisine) is a fast-acting mealtime insulin that lowers your blood sugar. The thing to know here is that maritime pine bark may also nudge blood sugar down a bit on its own. So when you stack the two together, the effects can add up, and your blood sugar could drop lower than you expect.

That means you'd want to watch for the usual signs of a low: shakiness, sweating, dizziness, a fast heartbeat, confusion, or feeling suddenly hungry. The evidence here is fairly limited (one small study), so this isn't a reason to panic. Just keep checking your glucose more closely if you add the supplement, and let your pharmacist or doctor know so they can decide if your insulin dose needs any tweaking. Please don't change your insulin on your own.
