Coconut and Insulin Aspart

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

Minor

ANTIDIABETES DRUGS

Why this applies to Insulin Aspart

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

Theoretically, taking coconut with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research suggests that coconut milk might increase insulin levels and/or decrease blood glucose levels.
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

Here's the gist: insulin aspart (Fiasp) already does the heavy lifting of lowering your blood sugar. The thought with coconut is that it might nudge your sugar down a little more on its own. If that happened on top of your insulin, your levels could dip lower than expected, which is what we call hypoglycemia (think shakiness, sweating, dizziness, or a racing heart).

Honestly though, I wouldn't lose sleep over this one. The concern comes only from animal studies, not from people, and it's rated minor and unlikely. Eating coconut as a normal food is very different from taking concentrated coconut supplements. If you do use larger medicinal amounts, just keep an eye on your readings and check in 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 Coconut

What is Coconut?

  • Skin and hair care
  • Source of dietary fats (MCTs)
  • Hydration with coconut water
  • Cooking and weight management
  • Antimicrobial (traditional use)

Coconut is a nutritious tropical food enjoyed as oil, water, milk, and flesh, and it is generally safe to eat in normal food amounts. While some uses (like skin moisturizing and hydration) have reasonable support, many health claims for coconut oil are weak or unproven, and coconut oil is high in saturated fat. Talk with your pharmacist or doctor before using coconut products in large or medicinal amounts.

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.
