Apple Polyphenols and Insulin Human, Sodium Chloride

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

Moderate

INSULIN

In healthy adults, taking 900-1800 mg of a polyphenol-rich apple extract prior to a meal delays the time to peak postprandial blood glucose levels. Theoretically, apple polyphenols might have additive effects when used concomitantly with certain insulin products and may increase the risk of hypoglycemia. Monitor blood glucose levels closely. Timing of insulin administration may need to be adjusted.
Severity Moderate Likelihood Probable Evidence B

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

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

Here's the gist: insulin (like Myxredlin) lowers your blood sugar, and concentrated apple polyphenol extracts may nudge it down a little too. In one lower-quality study, taking about 900 to 1800 mg of apple polyphenol extract before a meal slowed how quickly blood sugar peaked afterward. Stacked on top of your insulin dose, that could add up and push your sugar lower than you intended.

In real life, that means a slightly higher chance of hypoglycemia, things like shakiness, sweating, dizziness, hunger, or a fast heartbeat. This is mostly a concern with concentrated supplements, not a normal apple or two with a meal. If you'd like to try the supplement, check your blood sugar more closely at first and talk with your pharmacist or doctor before changing anything, since your insulin timing may need a tweak.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

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. Those are the only major-rated interactions among the 242 ingredients o…”

About Apple Polyphenols

What is Apple Polyphenols?

Apple Polyphenols
  • High cholesterol
  • High blood pressure
  • Weight management
  • Antioxidant support
  • Blood sugar support
  • Skin health (topical)

Apple polyphenols are antioxidant plant compounds taken from apples and marketed for heart, weight, and blood sugar health. Early research is interesting, but there is not enough reliable human evidence to confirm these benefits. They appear generally safe in food-like amounts, but talk with your pharmacist or doctor before using concentrated supplements.

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.
