Reports are voluntary and unverified — they record what someone experienced while taking something, not what the compound caused. Counts skew towards products people take a lot of, and a serious outcome is more likely to be reported than a mild one, so these are not rates. How we filter them →

What else affects it
Beyond other supplements
!
Caffeine excess
High caffeine may reduce immune benefits
Caffeine may interfere with immune enhancementHow it works
- Alkamides activate immune cells and enhance phagocytosis
- Polysaccharides stimulate macrophages and natural killer cells
- Caffeic acid derivatives provide anti-inflammatory effects
- Enhances interferon production for antiviral defense
- Increases white blood cell production and activity
- Modulates cytokine production for balanced immune response
Key findings
what the evidence supports- Good evidence for immune enhancement and cold prevention
- Most effective when taken at first sign of symptoms
- Short-term use (up to 10 days) recommended
- Quality and standardization vary significantly between products
