Do immunity shots actually work? What does the science say?
Quick answer
Yes — modestly and cumulatively. Daily 30ml shots of amla (vitamin C), turmeric (curcumin) and ginger (gingerol) have peer-reviewed evidence for anti-inflammatory and antioxidant effects. They don't prevent flu. They do support a stronger baseline immune response when consumed daily for 8+ weeks.
The key ingredients in immunity shots — particularly vitamin C from amla and lemon, curcumin from turmeric, and gingerols from ginger — have strong scientific support for supporting immune function. Vitamin C is essential for the functioning of both innate and adaptive immune cells. A landmark Cochrane review found that regular vitamin C intake reduced cold duration by 8% in adults and 14% in children.
