Chicory 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 Chicory interacts with.

Theoretically, chicory might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal and in vitro research shows that chicory extracts have antidiabetic effects.
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: Insulin aspart (Fiasp) already lowers your blood sugar, and some early research suggests chicory may nudge it down a little further. If both push in the same direction, you could end up lower than expected. That's where you might notice hypoglycemia, things like shakiness, sweating, a racing heart, dizziness, or feeling foggy and irritable.

I want to keep this in perspective, though. This concern comes mainly from animal and lab studies, not solid human data, so it's more theoretical than proven. A little chicory in coffee is unlikely to cause trouble, while concentrated supplement doses are more of a question mark. If you take chicory regularly, just keep checking your sugars and chat with your pharmacist or doctor before changing anything.

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. Most entries add to insulin's glucose-lowering effect, raising the risk of hypoglycemia, and with a rapid-acting mealtime insulin a low can become…”

About Chicory

What is Chicory?

Chicory
  • Constipation and digestive health
  • Source of prebiotic fiber (inulin)
  • Coffee substitute
  • Liver and gallbladder support
  • Appetite and blood sugar (traditional)

Chicory is best known as a caffeine-free coffee substitute and as a source of inulin, a soluble prebiotic fiber that may support digestion and regularity. Strong human evidence for most other traditional uses (like liver, gallbladder, or skin conditions) is limited. It is generally well tolerated, but the inulin can cause gas and bloating, and people allergic to ragweed or related plants should be cautious.

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.
