How Does Zinc Work?
Zinc helps the immune system by helping the white blood cells fight. It boosts their production of interferon-gamma, which is the body’s primary defense. It also stops invaders from spreading in the body. It stops invaders from entering and infecting our cells. Zinc also minimizes stuffiness, congestion, sneezing, and a runny nose by inhibiting the release of histamines that trigger those symptoms. This is also how over-the-counter remedies work for the same symptoms.
