- Thymosin Alpha-1
- TLR2 agonist; enhances T-cell maturation and cytokine balance via thymopoietin pathways
- 1.6mg subcutaneous twice weekly for 8–12 weeks
- High (23+ RCTs in viral hepatitis, cancer adjuvant therapy)
- Chronic viral infections, immune senescence, cancer immunotherapy adjuvant
- Gold standard for thymus-dependent immune restoration; requires subcutaneous injection and 8+ week protocol
- Astragalus Extract
- Polysaccharide-mediated macrophage activation; indirect T-cell support through cytokine modulation
- 500–2000mg oral daily
- Moderate (observational studies, limited RCTs)
- General immune support, adaptogenic stress response
- Effective for mild immune support; mechanism is indirect and less specific than Tα1
- Vitamin D3
- Upregulates antimicrobial peptides (cathelicidin, defensins); modulates innate immunity
- 2000–5000 IU oral daily, adjusted to serum 25(OH)D levels
- High (extensive observational and interventional data)
- Deficiency correction, respiratory infection prevention
- Essential baseline for immune function; works through different pathway than Tα1
- Beta-Glucan
- Binds complement receptor 3 on macrophages and neutrophils; primes innate immune response
- 250–500mg oral daily
- Moderate (RCTs in respiratory infections, post-surgical immune support)
- Upper respiratory infection prevention, post-operative recovery
- Effective for innate immunity priming; does not address adaptive immunity or thymic function
