There is no definitive answer to this question as the effectiveness of vitamin C in removing chlorine from water will depend on a number of factors, including the concentration of chlorine in the water and the specific formulation of vitamin C. However, some studies have shown that vitamin C can be effective in reducing chlorine levels in water, making it safer for consumption. As such, adding vitamin C to water that has been exposed to chlorine may help to reduce its unpleasant taste and odor.
