Astragalus and medications.
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 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.
Read the full methodologyA full supplement review, built around you, not a generic stack.
The free checker answers one interaction question at a time. A Distil report reviews the bigger picture: your goals, diet, medications, current supplements and any blood results you provide, then shows what appears worth keeping, changing, adding or leaving out.
- what your diet already covers, so you are not adding a capsule for something food is already handling
- which evidence-graded compounds are worth considering for your goals, and which were considered but left out
- what to keep, change or stop from what you already take, plus the order to introduce anything new
- how your medications and complete supplement stack fit together, with daily timing and a clear point for reassessment
The interaction check is one section of the full report. You also get the reasoning behind each recommendation and the evidence references used.
