Andrographis (maintenance dose)
What it is
At lower maintenance doses taken daily, andrographis acts as an immune modulator and mild adaptogen. Evidence at maintenance doses is weaker than the acute-cold treatment evidence. Small prevention trials (mostly with Kan Jang combination products) suggest modest reductions in upper-respiratory infection incidence with winter prophylaxis, but results are heterogeneous and mostly Russian/Scandinavian populations. Generally well tolerated for up to 3 months of daily use. Not for people on immunosuppressants.
Dose
100–200 mg/day standardised extract for immune maintenance; stronger evidence at 1,200 mg/day for acute illness
Time of day & tips
Take with food and water. Not for people on immunosuppressants. Allow 3–4 weeks for immune priming effect. Cycle off after 3 months and monitor for any liver enzyme changes.
