Last week, FFC published the results of a test it conducted on 47 brands of so-called vitamin-laced water, and found no Vitamin C in eight brands, including the Yanhee Vitamin C Water.

The company, however, insists there is Vitamin C in its product, adding that vitamins tend to vanish in reaction to oxygen, as well as heat, light and humidity.

It also said that it plans to provide training to vendors on how best to store vitamin-laced water, so it doesn’t lose its goodness.
