AHCC (Active Hexose Correlated Compound)
A polysaccharide complex extracted from Basidiomycota mushroom mycelium. Multiple clinical studies examine its ability to activate NK cells and macrophages to enhance immune function, particularly in cancer treatment support and infection prevention contexts.

Effects reported in research
Supports immune function via NK cell and dendritic cell activation
Clinical research on reducing side effects and immune suppression during chemotherapy
Some studies suggest accelerated HPV clearance
Dosage & timing
- 1–3 g/day.
- Often recommended on an empty stomach (1 hour before meals).
Cautions
- •Consult a doctor if on immunosuppressive medication (transplant patients, etc.) — immune activation may risk rejection.
- •Also use under medical supervision for autoimmune conditions.

Effects of probiotics on gut microbiota, IBS symptoms, and immune function: a meta-analysis
American Journal of Gastroenterology, 2014
A meta-analysis of 43 RCTs. Probiotics significantly improved global IBS symptom scores and abdominal pain compared to placebo (risk ratio 0.79). However, effects varied considerably by strain, with more consistent improvements seen in multi-strain Lactobacillus and Bifidobacterium products. Multiple studies also reported improvements in immune markers, including secretory IgA and inflammatory cytokines.
Meta-analysis of vitamin C supplementation on immune function and upper respiratory tract infection risk after exercise
American Journal of Clinical Nutrition, 1993
A meta-analysis examining the effects of vitamin C supplementation on upper respiratory tract infection (common cold) risk following intense exercise (marathon, etc.). Vitamin C supplementation reduced upper respiratory infection risk by approximately 50% compared to placebo. In the general population (lower exercise intensity), preventive effects are limited, suggesting the benefit is greatest in specific contexts where intense exercise causes immune suppression. Contributions to neutrophil and lymphocyte function and collagen synthesis are also documented.

Vitamin C
Confidence: ModerateAscorbic acid
A water-soluble antioxidant vitamin. Meta-analyses report only a modest ~8% reduction in colds in the general population, but about a 50% lower post-exercise upper-respiratory infection risk in people doing intense endurance exercise such as marathons. It also acts as a coenzyme in collagen synthesis, aids iron absorption, and supports immune-cell function.
Alpha-Lipoic Acid (ALA)
Confidence: ModerateAlpha-lipoic acid (racemic mixture of R- and S-isomers)
A versatile antioxidant that functions in both water- and fat-soluble environments. Studied for improving insulin sensitivity, enhancing glucose uptake, and regenerating other antioxidants (glutathione, vitamins C and E).
Garlic
Confidence: ModerateGarlic (Allium sativum) extract, containing allicin
A herb with allicin as its primary active compound. Multiple clinical studies demonstrate effects on blood pressure reduction, LDL lowering, immune enhancement, and antimicrobial activity.
