D-Hist 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.

D-Hist 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.


Equivalent to Hist-A-Core Jr. May be substituted without notice, containing the same ingredients under the The James Clinic label.
