Hawthorn and Heart Medicine: The Digoxin Warning
Hawthorn and heart medicine need a doctor's say-so. Memorial Sloan Kettering says lab data suggest hawthorn may interfere with digoxin, because it contains digoxin-like compounds, and may add side effects of antiplatelets and anticoagulants. People on heart medicines should use it only under physician direction. Protoflow lists hawthorn at 250 mg per 2 capsules.

Why would hawthorn affect digoxin?
Hawthorn contains digoxin-like compounds, so lab data suggest it may interfere with the drug (MSK, Hawthorn).
Digoxin is a heart medicine with a narrow safe range, and NIH flags narrow-range drugs as where herb interactions matter most (NCCIH, Herb-Drug Interactions). The same digest warns that most identified herb-drug links are hypothetical or based on indirect evidence. Hypothetical is not harmless; it means unproven either way.
Keep taking it exactly as prescribed. Ask the prescriber about the supplement, not the other way round.
Which other heart medicines does hawthorn touch?
The source lists antiplatelets, anticoagulants and drugs processed by the CYP3A4 enzyme, with unknown clinical relevance.
| Medicine type | Concern |
|---|---|
| Digoxin | May interfere (digoxin-like compounds) |
| Antiplatelets, anticoagulants | May add to side effects |
| CYP3A4-processed drugs | May alter metabolism |
| Blood pressure drugs | Data conflicting |
The source says the clinical relevance is unknown. That wording cuts both ways.
What does the Protoflow bottle tell a heart patient?
One general caution: if you take any medication, consult a physician before use (Protoflow bottle label).
The label never names digoxin, and the hawthorn line is 250 mg per serving, tied for the largest on the panel. Epimedium has its own heart note, with case reports of rapid heartbeat (MSK, Epimedium).
- Bring the panel to your cardiology visit
- Name every supplement, even occasional ones (NIH ODS, Dietary Supplements: What You Need to Know)
- Report new palpitations or dizziness at once

See packsWhere does a man with heart disease go from here?
To the prescriber, with the label in hand. Heart disease and erection trouble often travel together (NIDDK, Erectile Dysfunction).
That makes a men's capsule tempting and a talk more useful. Read the broader supplements and medicines guide, and the companion post on hawthorn berry for blood pressure.
FAQ01
Protoflow questions people ask
Is hawthorn tested with digoxin in people?
The Memorial Sloan Kettering page rests on lab data, and it says the clinical relevance is unknown. That is why it urges physician direction.
What are digoxin-like compounds?
Substances in hawthorn that resemble the drug digoxin chemically. They are the reason lab data suggest interference.
Could hawthorn matter if I take a heart rhythm pill other than digoxin?
The pages we read do not cover every drug. Ask a pharmacist, since hawthorn can also cause an irregular heartbeat in overdose.
Can I space hawthorn and heart medicine apart?
No source we read gives a safe gap, so spacing doses is not a proven workaround. Ask the prescriber.
What should I tell a cardiologist about Protoflow?
Show the Supplement Facts panel: hawthorn 250 mg, epimedium 250 mg, ginkgo 120 mg, ginseng 120 mg and cayenne 20 mg per 2 capsules.
