Natural D-Hist

Natural D-Hist offers optimal support for nasal and sinus passageways. Natural D-Hist is formulated for maximum effectiveness, with carefully selected dosages of critical natural components to provide optimal support for nasal and sinus passageways during the seasons as needed. Natural D-Hist contains:

Quercetin – A  powerful natural flavonoid, quercetin has also been shown to inhibit mast cell degranulation and its unfortunate consequences.

Stinging Nettles Leaf - Stinging Nettles components have been shown to block important enzymes within the arachidonic acid cascade as well as having proven their effectiveness in a single ingredient clinical trial.

Bromelain - A strong pineapple enzyme, bromelain has proven mucolytic properties. As such, bromelain supports normal mucosal tissue function and enhances the absorption of quercetin.

N-Acetyl L-Cysteine (NAC) - An amino acid that is also a natural mucolytic, NAC reduces the viscosity of mucus. Clinical studies have proven oral doses of NAC to be an excellent means to recharge cellular glutathione, a foundational antioxidant.
