Histacalm JR.

Histacalm JR.

Histacalm JR. is a great-tasting, chewable tablet that includes a targeted blend of flavonoids, antioxidants, proteolytic enzymes and botanicals designed to provide comprehensive support for children with seasonal challenges caused by common environmental allergens. Histacalm JR. includes quercetin, a powerful flavonoid to support healthy histamine levels. It supplies bromelain to enhance the absorption of quercetin and to support mucosal tissue health and stinging nettles leaf to balance hyper-immune response. N-acetyl cysteine clears the airways by promoting normal viscosity of mucus. This unique nutritional combination safely promotes healthy nasal and sinus passages for children with elevated histamine and respiratory irritation.
