The hero ingredient here is lactoferrin, an anti-viral, anti-bacterial, anti-inflammatory protein that is an immune modulator, doing its work to protect you from germs via the eyes, nose, mouth, and certain white blood cells. Chew one of these daily, and the combination of the lactoferrin, vitamin C, and zinc begins its good work in the mouth before making its way into the body, optimising immune function, and potentially nipping incipient illnesses in the bud. Very clever and paving the way for how immune-boosting supplements will invariably look in the future.
