Do immunity shots actually work? What does the science say?
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.
