Ceylon Cinnamon and Insulin Human, Sodium Chloride

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Insulin Human, Sodium Chloride

Insulin Human, Sodium Chloride falls under ANTIDIABETES DRUGS — the group Ceylon Cinnamon interacts with.

Theoretically, Ceylon cinnamon may have additive effects with antidiabetes drugs.
Ceylon cinnamon may lower blood glucose levels. Dose adjustments might be necessary.
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 simple version: insulin already does the heavy lifting of lowering your blood sugar. Ceylon cinnamon, at least in lab and animal studies, may nudge blood sugar down a little too. Put the two together and the effects could stack, meaning your sugar might dip lower than you expect. That could show up as the usual signs of a low: shakiness, sweating, a fast heartbeat, dizziness, or feeling foggy and irritable.

I'll be honest, this is mostly theoretical and the evidence is weak, so a sprinkle of cinnamon on your oatmeal is very unlikely to matter. Concentrated cinnamon capsules taken daily are where I'd pay closer attention. If you want to start a supplement, check with your pharmacist or doctor first and keep an eye on your glucose readings. Don't change your insulin on your own.

From our pharmacist’s overview on the Insulin Human, Sodium Chloride page

“The two entries to understand first for Myxredlin (human insulin in sodium chloride) are Siberian cocklebur, which has caused severe hypoglycemia in humans, and EDTA chelation products, which can drop blood glucose sharply and may interfere with the insulin itself.

About Ceylon Cinnamon

What is Ceylon Cinnamon?

Ceylon Cinnamon
  • Blood sugar support
  • High cholesterol
  • Indigestion and gas
  • Antimicrobial
  • General flavoring and culinary use

Ceylon cinnamon is the so-called 'true' cinnamon, valued as a spice and used in traditional medicine for blood sugar, cholesterol, and digestion. Evidence for most health benefits is limited and mixed, but as a food it is generally safe and contains far less coumarin than common cassia cinnamon. Talk with your pharmacist or doctor before taking concentrated supplements, especially if you have a health condition or take medications.

About Human Insulin Injection

What Is Human Insulin Injection Used For?

Brand name: Myxredlin

Novolin (human insulin injection) is used to improve glycemic control — meaning blood sugar management — in adults and children with diabetes mellitus.

Novolin 70/30 is a fixed-ratio mixture of intermediate-acting and short-acting human insulin. Because the ratio is fixed, it cannot be adjusted separately for background (basal) or mealtime (prandial) needs.
