Hyperbiotics PRO-Kids ENT is formulated with 5 targeted probiotic strains to help support children's inner ear, nose, and throat health, in addition to supporting their immune system and healthy teeth.* The mouth is the gatekeeper of our health and its beneficial bacteria plays a critical role in our immune system's first line of defense. The strains in PRO-Kids ENT work to support the balance of the flora in the oral cavity and allow room for the good bacteria to thrive. Studies indicate that S. salivarius K12 can start to support immune function within just 24 hours.* When beneficial bacteria are plentiful in the throat and pharynx, they help to create a barrier against invaders that can lead to unpleasant ear, sinus, and chest issues.*
