The bottom line No known interaction

We found no known interaction between Irvingia Gabonensis and Calcium Carbonate in our sources.

Interaction report

Irvingia Gabonensis and Calcium Carbonate

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 Calcium Carbonate and Irvingia Gabonensis 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.

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.

Irvingia Gabonensis safety at a glance

Irvingia Gabonensi... overall Use caution Generally tolerated short-term in studies, but long-term safety and product quality are not well established.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Calcium Carbonate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Calcium Carbonate is filed under 2 classifications — antacids, oral drugs. Irvingia Gabonensis has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and testosterone (moderate) — and none of Calcium Carbonate’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Irvingia Gabonensis Itself Has Been Linked To

This is not an interaction — nothing below involves Calcium Carbonate. It is the side-effect record for Irvingia Gabonensis on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Irvingia Gabonensis, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Yellowing of the skin or eyes / Liver problems Worth acting on Additional detail

    “One case of acute hepatitis secondary to Irvingia gabonensis has been reported. A 45-year old male with a ten-day history of Irvingia gabonensis supplementation, at a dose of 350 mg of seed extract twice daily for body fat reduction, was admitted with jaundice, abdominal discomfort, and new onset malaise. His complaints began four days after starting Irvingia gabonensis supplementation.”

Overlapping uses

What Calcium Carbonate Is Prescribed For, and What Irvingia Gabonensis Has Been Studied For

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

Calcium Carbonate is prescribed for: Most calcium carbonate products are used as an antacid — they quickly relieve heartburn, acid indigestion, sour stomach, and upset stomach. This covers a wide range of brands including Tums, Rolaids, CAREONE Extra Strength, Calcium Carbonate Chewable Antacid, exchange select Extra Strength Antacid, Extra Strength Smooth, and the Children's Antacid and Children's Stomach Relief Antacid liquids. Some products go beyond antacid use. Ki No Sin (capsule) is used as a health supplement to aid body functions affected by diabetes and kidney disease, and to help maintain normal calcium levels.

Na Mi Cal is a supplement intended to support healthy bone development and help prevent osteoporosis. TC Max oral solution is indicated for the relief of heartburn, acid indigestion, sour stomach, and upset stomach.

Irvingia Gabonensis has been studied for:

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

    Irvingia Gabonensis for diabetes

    It is unclear if oral Irvingia gabonensis is beneficial in patients with diabetes.

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 Calcium Carbonate on your own; if you are taking Irvingia Gabonensis for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Calcium Carbonate

This page covers Irvingia Gabonensis only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Calcium Carbonate page lists 30 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Cinchona (moderate), Coffee Charcoal (moderate), European Mandrake (moderate) and Glucomannan (moderate).

By severity: 1 major · 10 moderate · 19 minor.

From our pharmacist’s overview on the Calcium Carbonate page

“Calcium carbonate (Tums, Os-Cal) feels like the most harmless thing in the medicine cabinet, which is exactly why its supplement list deserves a careful read, led by activated charcoal, the single major-rated entry. Charcoal adsorbs many medicines in the gut and can strip away their effect, and it does not spare oral drugs taken alongs…”

About Irvingia Gabonensis

What is Irvingia Gabonensis?

Irvingia Gabonensis
  • Weight loss
  • Appetite control
  • Cholesterol support
  • Blood sugar support
  • Metabolism support

Irvingia gabonensis (African mango) is a seed extract marketed mainly for weight loss and metabolic health. A few small studies suggest possible benefits, but the research is limited and low-quality, so the true effect is uncertain. Talk with your pharmacist or doctor before using it, and do not rely on it in place of proven diet and lifestyle changes.

Irvingia gabonensis · Irvingiaceae · Seed (kernel, also called dika nut); seed extract · Capsules, tablets, powder, standardized seed extract

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

Irvingia Gabonensis: dosing

There is no officially established or standardized dose for Irvingia gabonensis. Studies have used different seed extracts and amounts, so it is hard to recommend one specific dose.If you choose to try it, follow the directions on the product label and do not exceed them.

They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together.

That is a conversation for your prescriber, especially if Calcium Carbonate is being adjusted to a target.
How was the Irvingia Gabonensis and Calcium Carbonate combination checked?
Interactions in our licensed database are recorded against drug classes. Calcium Carbonate is filed under 2 classifications, and Irvingia Gabonensis has documented interactions with 2 drug classes — none of Calcium Carbonate's classifications are among them.
