Ergogenic Aids + Crizotinib
Crizotinib brand name: Xalkori.
We found no known interaction between Ergogenic Aids and Crizotinib 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.
Ergogenic Aids and Crizotinib
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 Crizotinib and Ergogenic Aids 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 Ergogenic Aids at all — not against Crizotinib, 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.

From our pharmacist’s overview on the Crizotinib page
“Grapefruit tops my worry list for crizotinib (Xalkori), a targeted pill for ALK-positive lung cancer. It blocks the enzyme (CYP3A4) that clears crizotinib, letting levels climb and side effects with them, and it is one of eight major-rated entries among the 157 supplements and herbs on file for this drug.”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Ergogenic Aids 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 Ergogenic Aids reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Ergogenic Aids and Crizotinib records this page draws on were last updated July 10, 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 Ergogenic Aids
What is Ergogenic Aids?
- Boosting athletic performance
- Increasing muscle strength and power
- Improving endurance
- Supporting muscle growth and recovery
- Reducing fatigue during exercise
"Ergogenic aids" is a broad term for substances, foods, or techniques used to enhance exercise performance, training, or recovery. A few have solid evidence (such as caffeine, creatine, and beta-alanine), while many others have weak or no proof. Quality and safety vary widely, so talk with a pharmacist or doctor before using any of them.
Not applicable (ergogenic aids are a broad category, not a single plant) · Powders, capsules, tablets, drinks, gels, and bars
An interaction check asks whether these two react with each other — it does not ask whether Ergogenic Aids is a good idea for someone in your situation. Here is what our Ergogenic Aids record says about it on its own.
Ergogenic Aids: dosing
There is no single standard dose for "ergogenic aids" because the term covers many different substances. The right amount depends entirely on the specific ingredient.Follow the directions on the product label, and do not assume that taking more will work better. Higher doses often raise the chance of side effects without adding benefit.Because quality and ingredients vary so much, choose products from reputable companies, ideally ones that have been third-party tested. A pharmacist can help you review the label and decide whether a specific product is appropriate for you.
