Natural D-Hist™
Enjoy the Outdoors Once Again

Ortho Molecular Products
Because Efficacy Matters®

  • Support for Nasal & Sinus Passageways
  • Won't Cause Drowsiness

If you are like the 40 million Americans who shy away from the outdoors during the height of the growing season, you have likely tried every over-the-counter product on the market.

Unfortunately, most products force your body to function in a way that is not natural, hence the many side effects associated with these products.

Why is Natural D-Hist Different?
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?
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 that stinging nettles demonstrate positive support for nasal passageway function.  While further study is needed, stinging nettles in supplementation demonstrated measurable support after only 1 week.

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 that when given NAC, individuals were supplemented appropriately without side effects.

Formulated to be free of allergens derived from:  Gluten, corn, yeast, artificial colors and flavors.
