Innate immunity & trained immunity
One of 5 mechanistic pathways to 🛡️ Immune resilience · 15 options
The innate system responds in minutes without prior exposure, and it can be 'trained' — beta-glucans and similar molecules prime monocytes epigenetically so they answer harder next time. This is a real and relatively recent immunological concept, not a marketing one.
Neutrophil count and CRP describe the innate system's resting state. Vitamin D drives the antimicrobial peptides this arm depends on, which is much of why status tracks with infection rate.

What engages this pathway
Ordered by how directly each one acts on the mechanism above — never by how much trial evidence exists. Each links to its full breakdown with dosing, half-life and vendor.
🧬 Beta-Glucans
Bind dectin-1 on macrophages and neutrophils, priming the innate response. Trials show reduced upper-respiratory infection incidence in athletes and stressed populations. The 1,3/1,6 yeast-derived form is what was studied.
🧬 AHCC
Shiitake mycelia extract with real trial data — including randomised evidence for clearing persistent HPV infection, which is an unusually specific result for a mushroom extract.
🧬 Turkey Tail
PSK is an approved adjuvant cancer therapy in Japan, with survival data in gastric and colorectal cancer. The strongest clinical evidence of any medicinal mushroom.
🧬 Maitake
D-fraction beta-glucans with NK-cell activation in preclinical work.
🧬 Shiitake (Lentinan)
Lentinan is used intravenously as a cancer adjuvant in Japan; oral evidence is weaker.
🧬 Chaga
High in betulinic acid and melanin with antioxidant and immunomodulatory activity in vitro. Very high oxalate content is a real kidney-stone concern with heavy use.
🧬 Agaricus blazei
Beta-glucan source with NK-cell activity in small trials.
🧬 Reishi
Triterpenes and polysaccharides with immunomodulatory rather than stimulatory activity — it appears to normalise rather than amplify.
🧬 Astragalus
Polysaccharides increase T-cell and NK activity; used as an adjuvant in Chinese oncology practice with meta-analysis support.
🧬 Colostrum
Supplies IgG, lactoferrin and growth factors. Reduces upper-respiratory infection incidence in athlete trials.
🧬 Lactoferrin
Sequesters iron away from bacteria, disrupts membranes and modulates the immune response. Trial evidence in infant infection and, more recently, in respiratory viral illness.
💉 LL-37
The body's own cathelicidin antimicrobial peptide — vitamin D upregulates its expression, which is part of why D status matters for infection.
🧬 Bee Pollen
A broad micronutrient and flavonoid source with immunomodulatory activity in animal work. Real anaphylaxis risk in anyone with pollen or bee allergy.
🧬 Spirulina
Phycocyanin has immunomodulatory and antioxidant activity, with trials showing increased NK-cell activity and reduced allergic rhinitis symptoms. Source matters — it concentrates whatever is in its water.
🧬 Colloidal Silver
Broad antimicrobial in vitro, and no controlled human evidence of internal benefit. Chronic ingestion causes argyria — permanent blue-grey skin discolouration that does not reverse. Listed so the risk is on the record, not because it belongs in a protocol.

Frequently asked questions
The innate system responds in minutes without prior exposure, and it can be 'trained' — beta-glucans and similar molecules prime monocytes epigenetically so they answer harder next time. This is a real and relatively recent immunological concept, not a marketing one.
15 options are mapped to this pathway in the Vault, including Beta-Glucans, AHCC, Turkey Tail, Maitake. They are grouped by the mechanism they act through rather than ranked by how much trial evidence exists — 9 carry clinical validation and 5 are mechanistic predictions.
Neutrophil count and CRP describe the innate system's resting state. Vitamin D drives the antimicrobial peptides this arm depends on, which is much of why status tracks with infection rate. The markers worth checking are Complete Blood Count (CBC) with Differential, hs-CRP (High-Sensitivity C-Reactive Protein), Vitamin D (25-Hydroxy), Zinc, RBC.
Unproven is not the same as ineffective. Of the 15 options on this pathway, 9 have clinical validation and 5 are graded theoretical — meaning the mechanism is sound but the specific human trial has not been run, which is true of a great deal of what works in this space. Nothing on this page is ordered by evidence tier, because sorting by trial count would bury the compounds you came looking for.
