How to build this immune system support stack

A practical 3-step protocol for assembling this stack. Layer ingredients in evidence order, give each ingredient time to register, and reassess at the 4–8 week mark.

  1. 1

    Start with the strongest evidence ingredient

    Begin with Andrographis Paniculata, the highest-evidence ingredient in this stack with 3 indexed PubMed citations.

  2. 2

    Layer in complementary mechanisms

    Add Agaricus Blazei Mushroom (Agaricus subrufescens) and African Medlar to cover complementary pathways.

  3. 3

    Cycle and assess at 4-8 weeks

    Most clinical effects emerge after 4-8 weeks of consistent use. Reassess at the 8-week mark and adjust based on personal response.

Total time to assemble: ~3 minutes. Yield: a complete immune system support support protocol.
