the present invention provides a nutrient infuser removably attached to a drinking water source to remineralize drinking water . the nutrient infuser comprises a pipe provided for the drinking water to flow therethrough , wherein flow rate of the drinking water is measured by a flow meter . the flow meter converts flow rate into electronic signals which will be received by a controller . the controller totalizes the electronic signals and uses it to further generate another electronic signal to activate an injector to operate accordingly . upon activation , the injector draws a predetermined amount of consumable substances from a canister and injects the same to the drinking water flowing through the pipe , remineralizing the drinking water , making it healthier for consumption . the predetermined amount of consumable substances injected to the drinking water corresponds to the flow rate of the drinking water . the consumable substances may comprise essential minerals , vitamins or flavoring .
