Miracle Fruit and Insulin Aspart

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Insulin Aspart

Insulin Aspart falls under ANTIDIABETES DRUGS — the group Miracle Fruit interacts with.

Theoretically, miracle fruit leaf might have an additive effect with antidiabetes drugs and increase the risk of hypoglycemia. Evidence from an animal model shows that miracle fruit leaf increases insulin production and lowers fasting blood glucose and HbA1c in rats with streptozotocin-induced diabetes. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, metformin (Glucophage), pioglitazone (Actos), rosiglitazone (Avandia), and others.
Severity Moderate Likelihood Possible Evidence D

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 gist for insulin aspart (Fiasp): this is a fast-acting insulin you take to bring your blood sugar down. The concern with miracle fruit, specifically the leaf, is that it may also lower blood sugar on its own. Stack that on top of your insulin and the two effects could add up, nudging your sugar lower than you intended.

That said, I want to be honest about the evidence. This is theoretical and comes only from a rat study, not from people. The sweet-tasting berry most folks try is not the same as concentrated leaf supplements. Still, if you do use miracle fruit leaf regularly, keep an eye out for low blood sugar signs like shakiness, sweating, or confusion, and chat with your pharmacist or doctor before mixing them.

From our pharmacist’s overview on the Insulin Aspart page

“Every one of the 239 supplements listed for insulin aspart (Fiasp) touches the same thing the drug exists to manage, blood sugar, so this list warrants genuine care rather than a quick skim.

About Insulin Aspart (rDNA Origin) Injection

What Is Insulin Aspart (rDNA Origin) Injection Used For?

Brand name: Fiasp

Insulin aspart is used to improve blood sugar (glucose) control in people with diabetes mellitus. It is approved for both type 1 and type 2 diabetes in adults, and for diabetes mellitus in pediatric patients.

Insulin Aspart Protamine and Insulin Aspart Mix 70/30 is a pre-mixed product that combines a rapid-acting and an intermediate-acting insulin aspart. It is approved to improve blood sugar control in adult patients with diabetes mellitus. It is not recommended for treating diabetic ketoacidosis, and because its ratio of rapid-acting to intermediate-acting insulin is fixed, it does not allow for separate mealtime versus background dose adjustments.
