Natural D-Hist is a targeted blend of flavonoids, antioxidants,
proteolytic enzymes and botanicals designed to provide
comprehensive support for seasonal challenges caused
by common environmental allergens. Natural D- Hist
includes quercetin, a powerful flavonoid, to support healthy
histamine levels. Bromelain enhances the absorption of
quercetin and supports mucosal tissue health. Stinging
nettles leaf balance hyper-immune response and N-acetyl
cysteine clear the airways by promoting normal viscosity
of mucus. This powerful combination actively promotes
healthy nasal and sinus passages for individuals with
elevated histamine and respiratory irritation.
