24 Jun 2020 --- To preserve the active ingredients in premixed vitamin waters, US-based Karma Water has employed cap technology that releases the nutrients in the drinks moments before consumption. Karma Cap ensures that the nutritional quality of the drinks remains intact. This comes as a Karma Water-endorsed bio-analytical study found that the key active ingredients found in premixed vitamin drinks and kombuchas diminish sharply over time and within the date code of bottling.
