Drug & supplement interaction

Sweet Cherry + Metformin

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Sweet Cherry and Metformin in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Sweet Cherry and Metformin

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Metformin and Sweet Cherry in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Sweet Cherry at all — not against Metformin, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

No Interaction Found — But Data Suggests Sweet Cherry and Metformin May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

Overlapping uses

What Metformin Is Prescribed For, and What Sweet Cherry Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Metformin is a prescription medicine with approved uses on its FDA label. Sweet Cherry is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Metformin is prescribed for: Metformin is used to improve blood sugar (glucose) control in people with type 2 diabetes mellitus. It is always used together with diet and exercise, not instead of them. Metformin hydrochloride tablets and oral solution are approved for adults and children 10 years and older. Metformin hydrochloride extended-release tablets — including brands such as Fortamet, Glumetza, and Metformin Hydrochloride Extended Release — are approved for adults only.

Sweet Cherry has been studied for:

  • Diabetes studied, not established Sweet Cherry has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Sweet Cherry for diabetes

    Although there has been interest in using oral sweet cherry for diabetes, there is insufficient reliable information about the clinical effects of sweet cherry for this condition.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Metformin on your own; if you are taking Sweet Cherry for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Metformin

This page covers Sweet Cherry only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Metformin page lists 258 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Siberian Cocklebur (major), Acai (moderate), African Wild Potato (moderate) and Agaricus Mushroom (moderate).

By severity: 2 major · 217 moderate · 39 minor.

From our pharmacist’s overview on the Metformin page

“Siberian cocklebur is the ingredient I most want anyone taking metformin (Glucophage) to know about. It has caused severe low blood sugar in people, documented in humans, and it should not be combined with any glucose-lowering medication.”

About Sweet Cherry

What is Sweet Cherry?

  • Joint pain and gout
  • Exercise recovery and muscle soreness
  • Sleep support
  • General antioxidant support
  • Inflammation

Sweet cherry (Prunus avium) is a popular fruit rich in antioxidants and natural plant pigments, and it is sometimes used as a supplement for gout, sore muscles, and sleep. The research that exists is mostly small or uses tart cherry rather than sweet cherry, so benefits are not well proven. Eaten as food, cherries are very safe, but talk to your pharmacist or doctor before using concentrated supplements.

Prunus avium · Rosaceae · Fruit (and fruit juice or extract); stems are used traditionally · Fresh or dried fruit, juice, juice concentrate, capsules, powders, and extracts

An interaction check asks whether these two react with each other — it does not ask whether Sweet Cherry is a good idea for someone in your situation. Here is what our Sweet Cherry record says about it on its own.

Sweet Cherry: dosing

There is no official or standardized dose for sweet cherry as a supplement. Studies have used different forms and amounts, and most used tart cherry, so the right dose for sweet cherry is not established.If you use a cherry juice, concentrate, powder, or capsule, follow the directions on the product label. Do not assume more is better.

Taking Sweet Cherry and Metformin Together: Common Questions

Is it safe to take Sweet Cherry with Metformin?
We do not list a known interaction between Sweet Cherry and Metformin. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Sweet Cherry and Metformin have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Sweet Cherry and Metformin used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Sweet Cherry in each. That is a conversation for your prescriber, especially if Metformin is being adjusted to a target.
Does Metformin interact with any supplements?
Yes. Metformin has documented interactions with 258 supplements in our database — Sweet Cherry is not one of them. The Metformin interaction page linked on this page lists every one, ranked by severity.
