Natural D-Hist is the ideal solution for many of the 40 million Americans who anticipate seasonal changes. Formulated for maximum effectiveness, Natural D-Hist utilizes carefully selected natural components to provide optimal support for nasal and sinus passageways.
Why These Natural Ingredients?
Quercetin - Naturally found in onions, quercetin supports mast cell stability and is a powerful natural flavonoid. Quercetin has been shown to promote sinus and respiratory health.
Stinging Nettles Leaf - Studies have shown stinging nettles to demonstrate positive support for nasal passageway function. While further study is needed, stinging nettles in supplementation demonstrated measurable support after only one week.
Bromelain - A strong pineapple enzyme, bromelain supports normal mucousal tissue function and enhances the absorption of quercetin.
N-Acetyl L-Cysteine (NAC) - An amino acid, NAC helps to promote the normal viscosity of mucus. Studies have shown individuals have been supplemented appropriately without side effects when given NAC.
