The active ingredients found in premixed vitamin drinks diminish sharply over time. So while there may be the stated level of vitamins at the time of bottling, there may be substantially less by the time you drink it. While other brands may make empty promises, Karma’s patented Push Cap protects the active ingredients until the minute you’re ready to drink – guaranteeing you’ll receive the highest level of nutritional benefits. Karma’s Push Cap is the only dispensing cap with a hermetic seal, providing an airtight chamber to optimize freshness and potency.
