Immune Adaptogens
Astragalus vs Reishi
Astragalus is the daily immune tonic; Reishi is the nervous-system-calming immune modulator.
Both have centuries of traditional Chinese medicine use for immune support and long life, but they do different things. Astragalus increases T-cell and NK-cell activity — it's more of an immune-revving tonic. Reishi (Ganoderma lucidum) is adaptogenic: it balances overactive immunity (useful in autoimmunity) while calming the parasympathetic system and supporting sleep.
Botanical
Astragalus root extract is a traditional Chinese medicine ingredient studied for potential immune-supporting and adaptogenic properties. Evidence for human efficacy is limited and primarily from small trials, with most research conducted in Asia.
Typical dose: 500-1000mg extract 2-3x daily
Main uses: Immune modulation · Prevention · Adaptogen

Main uses: Immune modulation · Sleep quality · Stress adaptation
Full Reishi profile →When to pick Astragalus
Pick Astragalus for daily immune support, frequent colds, or as a longevity tonic. Best evidence is in cancer patients on chemotherapy (adjunct, not replacement). Dose: 2–6 g/day of root, or 500–1,000 mg/day of a 15:1 extract.
When to pick Reishi
Pick Reishi if you want the immune benefit bundled with stress reduction, better sleep, or blood pressure lowering. Good choice for autoimmune conditions where Astragalus could over-stimulate. Dose: 1.5–3 g/day of dual-extracted powder.
Can you take them together?
Often stacked in TCM-inspired longevity formulas. Mechanisms overlap but aren't redundant. Watch Reishi with blood thinners — modest anticoagulant effect. Astragalus may stack with immunosuppressants in problematic ways; check with a clinician if on them.
