19-nor-dhea and Rosiglitazone Maleate

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 Rosiglitazone Maleate and 19-nor-dhea 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.

How we checked

Why No Interaction Is Listed for Rosiglitazone Maleate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Rosiglitazone Maleate is filed under 6 classifications — including cytochrome p450 2c8 (cyp2c8) substrates, antidiabetes drugs, cytochrome p450 2c9 (cyp2c9) substrates. 19-nor-dhea has documented interactions with 1 drug class — the most serious being testosterone (moderate) — and none of Rosiglitazone Maleate’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.

From our pharmacist’s overview on the Rosiglitazone Maleate page

“Rosiglitazone (Avandia) lowers blood sugar in type 2 diabetes, and most of the 314 supplements and herbs on this page pull on that same lever. Some 239 can move blood glucose on their own, so adding one risks hypoglycemia, the shakiness, sweating, and confusion of sugar falling too low.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. 19-nor-dhea is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every 19-nor-dhea reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified October 4, 2026. The 19-nor-dhea and Rosiglitazone Maleate records this page draws on were last updated June 20, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About 19-nor-dhea

What is 19-nor-dhea?

  • Muscle building and bodybuilding
  • Increasing strength
  • Athletic performance
  • Supporting hormone levels
  • Body recomposition

19-nor-DHEA is a synthetic 'prohormone' marketed to bodybuilders as a precursor to nandrolone-like compounds, not a natural plant supplement. There is very little reliable human research on its safety or effectiveness, and products like it carry real risks to the liver, hormones, and heart. We do not recommend using it without close medical supervision, and it may be banned in sports and restricted by law in some places.

Not applicable (a synthetic or semi-synthetic hormone derivative, not a plant part) · Capsules, tablets, sublingual tablets, sometimes combined in 'prohormone' supplement blends

An interaction check asks whether these two react with each other — it does not ask whether 19-nor-dhea is a good idea for someone in your situation. Here is what our 19-nor-dhea record says about it on its own.

19-nor-dhea: dosing

There is no established or medically recommended dose for 19-nor-DHEA. It has not been studied well enough to define a safe and effective amount.Products vary widely, and labels may not be accurate. Because of this, we cannot suggest a specific milligram amount.

About Rosiglitazone

What Is Rosiglitazone Used For?

Brand name: Avandia

  • Rosiglitazone is used along with a diet and exercise program and sometimes with one or more other medications to treat type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood). Rosiglitazone is in a class of medications called thiazolidinediones. It works by increasing the body's sensitivity to insulin, a natural substance that helps control blood sugar levels. Rosiglitazone is not used to treat type 1 diabetes (condition in which the body does not produce insulin and therefore cannot control the amount of sugar in the blood) or diabetic ketoacidosis (a serious condition that may occur if high blood sugar is not treated).

  • Over time, people who have diabetes and high blood sugar can develop serious or life-threatening complications, including heart disease, stroke, kidney problems, nerve damage, and eye problems. Taking medication(s), making lifestyle changes (e.g., diet, exercise, quitting smoking), and regularly checking your blood sugar may help to manage your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other diabetes-related complications such as kidney failure, nerve damage (numb, cold legs or feet; decreased sexual ability in men and women), eye problems, including changes or loss of vision, or gum disease. Your doctor and other healthcare providers will talk to you about the best way to manage your diabetes.
