Supplement · Considered, not recommended

Astragalus and medications.

Why it sits outside our recommendations, and what to consider instead.

Astragalus is not in the Distil recommendation database. We surface it here deliberately, because why a compound is left out is as useful as what we recommend.

Astragalus has the same core issue as echinacea: it is an immune-active herb that the Distil pipeline cannot safely carry across an immunosuppressed or autoimmune profile. Used in traditional practice as a general tonic and immune support, it is characterised primarily as an immune stimulant, which makes it inappropriate for anyone on an immunosuppressant or with an autoimmune condition, both of which the pipeline screens for.

Outside that group, the human evidence for its headline claims is thin. Between the safety screen and the weak evidence, it stays out of the database. For resilience and stress the adaptogens below have better human data, and for immune support the basics do more.

What to consider instead. Every option below is in the Distil database, so you can check each against your own medications:

Ashwagandha: better-studied adaptogen for stress; note its own thyroid caveat
Rhodiola Rosea: for fatigue and stress; check against serotonergic medicines
Vitamin D3: the higher-yield move for immune support in most people

We do not currently hold documented medication interactions for Astragalus in the database. The checker below will surface anything as it is added, and the missing-item form routes uncatalogued pairs into our next curation pass.

What this page does not say. Leaving a compound out of our recommendations is not a verdict that it is useless for everyone. It is a statement about safety, evidence, or interaction load in the context Distil screens for. Discuss any supplement decision with whoever manages your prescriptions.

How we decide

How we grade severity, choose what's in scope, and what we exclude.

Every call on this page is reasoned. We publish the full rubric for severity tiers, the medication inclusion logic, the evidence grades we accept, and what we deliberately leave out. About three thousand words. Worth reading once if you use this tool more than occasionally.

Your whole stack

Want this checked across everything you take?

This page checks the pairs you enter. The personalised Distil report goes further:

the same graded, cited interaction check across your whole stack, not just the pairs you thought to type in
where your current routine may be leaving you short of your goals
the evidence-graded compounds worth adding, and the ones worth dropping

It's a paid report: £79, or £49 founder pricing while we earn our first reviews. The interactions check is one section of it, and you can read a real one in full before you decide.

Something missing?

If a supplement or medication you take isn't in our autocomplete, tell us. We go through what people flag every week and add what's missing.

Thanks, that's logged. We go through flagged items every week.

Distil's interactions database is reviewed and updated every quarter. We grade evidence transparently and publish our methodology, including every database change, at /about/methodology. This tool is information, not a substitute for clinical judgement. If you take medication and supplements together, your GP or pharmacist can review your full regimen against your medical history. If you want a full personalised stack reasoned against this same database, the Distil report is the next step up.
