Hista Pro

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.
