'Intensified' Drink?

Received Package today and have one question

I have received the V-Diet package today. It came with a 2000 ml container and something called intensified. How to consume the intensified? Is it a water substitute or something to sip all day? It is only for workout days or for every day?

The Intensified Liquid Flavoring System is for the Plazma, which is unflavored.
