Full Alfalfa + Tretinoin answerWhat Severity, Likelihood & Evidence Mean
Severity — How Serious It Can Be
- Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
- Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
- Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
- No known interaction. Checked against our sources with nothing documented — not the same as proven safety.
Likelihood — How Well It’s Documented
- Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
- Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
- Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
- Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Where This Data Comes From
- Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.
- Each entry links to a full report with the clinical detail, likelihood, evidence level, and citations for that exact combination.
- Content is reviewed by licensed HelloPharmacist pharmacists — see our data sources and editorial standards.
How Does Our Interaction Checker Work?
Behind every verdict on this page is a category system. Our source database doesn’t document supplement interactions drug-by-drug — it documents them against groups of medications that behave the same way (for example, “drugs processed by the CYP3A4 liver enzyme” or “blood-thinning medications”).
So the check works in three steps: (1) Tretinoin is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Tretinoin, and (3) each ingredient keeps its own severity, likelihood, and evidence grades from the underlying record. That’s why one supplement can carry several records for one drug — it may interact through more than one category.
Tretinoin sits in 5 interaction categories. Open any one to see what the group means:
Photosensitizing Drugs 20 ingredients
Medications that make skin more sun-sensitive. Supplements with the same property can compound it.
20 of the supplement ingredients on this page reach Tretinoin through this category.
Oral Drugs 17 ingredients
A pharmacology grouping from our source database: medications in this group share a property that certain supplements are known to interact with, so an interaction documented for the group applies to every drug in it.
17 of the supplement ingredients on this page reach Tretinoin through this category.
Cytochrome P450 2C8 (Cyp2C8) Substrates 11 ingredients
A drug-metabolism group: these medications are processed by the named liver enzyme (a cytochrome P450). Supplements that speed this enzyme up or slow it down can lower or raise the medication's levels in your body.
11 of the supplement ingredients on this page reach Tretinoin through this category.
Topical Drugs 3 ingredients
A pharmacology grouping from our source database: medications in this group share a property that certain supplements are known to interact with, so an interaction documented for the group applies to every drug in it.

Where This Data Comes From — and Why You Can Trust It
🧪 Licensed clinical database
Every interaction verdict on this page comes from Natural Medicines Pro (TRC Healthcare / Therapeutic Research) — the same evidence-graded reference used by pharmacists and hospitals. We license this data directly; we do not scrape it, and no AI invents an interaction.
🧑⚕️ Pharmacist review
This page is curated and coded by Dr. Brian Staiger, PharmD, BCPS, Clinical Pharmacist, with additional analysis by the HelloPharmacist Pharmacist Team. Editorial commentary is ours; the licensed interaction records are shown as sourced.
🔄 Kept current
Our interaction database refreshes on a weekly cycle, and this page re-checks the live database every time it’s rebuilt — what you see reflects the database as of September 24, 2026.
🔍 Full transparency
How every dataset on this site is sourced, licensed, and updated is documented publicly: our data sources · editorial policy · how we use AI.
Educational information, not medical advice. An interaction being on file does not mean it will happen to you — and absence of one is not proof of safety. Never start or stop a medication or supplement without talking to your pharmacist or doctor.
