The bottom line No known interaction

We found no known interaction between Phenethylamine (pea) and Rosuvastatin in our sources.

Phenethylamine (pea) and Rosuvastatin

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 Rosuvastatin and Phenethylamine (pea) 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 Rosuvastatin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Rosuvastatin is filed under 4 classifications — including hmg-coa reductase inhibitors ("statins"), hepatotoxic drugs, oral drugs. Phenethylamine (pea) has documented interactions with 2 drug classes — the most serious being monoamine oxidase inhibitors (maois) (moderate) and serotonergic drugs (moderate) — and none of Rosuvastatin’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.

This is not an interaction — nothing below involves Rosuvastatin. It is the side-effect record for Phenethylamine (pea) on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Phenethylamine (pea), this list is the first place to look.

From our pharmacist’s overview on the Rosuvastatin page

“Rosuvastatin (Crestor, Ezallor) is a statin taken daily for years to lower cholesterol, and its supplement list deserves real scrutiny, not a quick skim. Five of the 63 ingredients on file carry a major rating, headed by grapefruit, which can raise statin blood levels, and by heavy drinking, since beer and wine compound the strain this…”

About Phenethylamine (pea)

What is Phenethylamine (pea)?

Phenethylamine (pea)
  • Mood support
  • Focus and concentration
  • Energy and pre-workout boost
  • Feeling of well-being
  • Athletic performance

Phenethylamine (PEA) is a natural compound made in the body and found in foods like chocolate; supplements are marketed for mood, focus, and energy. Reliable human research on the supplement is very limited, and it may raise blood pressure or heart rate, so people with heart or blood pressure problems should be cautious and check with a pharmacist or doctor first.

Not a plant part; a naturally occurring monoamine compound (made in the body and found in some foods) · Capsules, tablets, powders (often combined with other ingredients in pre-workout or 'mood' and 'focus' supplements)

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

Phenethylamine (pea): dosing

There is no well-established or standardized dose for PEA supplements, and reliable studies on safe and effective amounts are lacking. Products vary widely in how much they contain and what else they are combined with.If you choose to try it, follow the directions on the product label and do not exceed the recommended amount.

About Rosuvastatin

What Is Rosuvastatin Used For?

Brand names: Crestor, Ezallor

Rosuvastatin tablets are used alongside diet changes to lower LDL-C ("bad" cholesterol), total cholesterol, and triglycerides (blood fats), and to raise HDL-C ("good" cholesterol) in adults with high cholesterol or mixed cholesterol problems. They are also used in adults with very high triglycerides, a condition called primary dysbetalipoproteinemia (Type III, a genetic fat-metabolism disorder), and to slow the buildup of plaque in arteries (atherosclerosis).

In people without established heart disease but with multiple risk factors, rosuvastatin tablets can reduce the risk of heart attack, stroke, and procedures to open blocked arteries. For children and teens aged 8 and older with heterozygous familial hypercholesterolemia (HeFH, an inherited high-cholesterol condition), the tablet form is used to lower LDL-C after diet alone has not worked. Crestor tablets are also approved to treat homozygous familial hypercholesterolemia (HoFH, a more severe inherited form) in adults and in children aged 7 and older.
