The Natural D-Hist formula includes optimal support for nasal and sinus passageways for individuals who anticipate seasonal changes
Won't Cause Drowsiness!
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. The formula includes quercetin, bromelain, stinging nettles leaf, and N-acetyl cysteine. The powerful combination actively promotes healthy nasal and sinus passages for individuals with elevated histamine and respiratory irritation.
Quercetin has strong antioxidant activity and has been shown to support immune health by mediating the release of inflammatory compounds including leukotrienes and prostaglandins. Quercetin is known for its ability to stabilize mast cells, diminishing the release of histamine, the compound known to cause hypersensitivity reactions during seasonal changes.
Stinging Nettles Leaf Extract
Stinging nettles leaf is a plant that has been shown to balance immune response, specifically in the airways and nasal passages. Studies have shown that the extract of stinging nettles leaf balances a variety of inflammatory activities that affect respiratory health.
Bromelain is a plant enzyme naturally found on the stem and fruit of the pineapple plant. Bromelain is a proteolytic (protein-digesting) enzyme that aids in in the breakdown of large protein complexes, including antigenic compounds, and has been shown to enhance the absorption of quercetin. Bromelain has been shown to reduce circulating allergenic protein complexes associated with hyper-immune sensitivity and seasonal discomfort.
N-acetyl cysteine (NAC) is an amino acid precursor to one of the most important antioxidants in the body, glutathione. Both glutathione and NAC help reduce the viscosity of the mucus allowing for clearing of the airways and improved respiratory health.
Vitamin C cannot be synthesized by humans and is therefore an essential nutrient that must be consumed in the diet. Among its numerous health-promoting properties, vitamin C is an essential vitamin that supports the immune system and is also a potent antioxidant. When the body is under a significant amount of stress, vitamin C is excreted rapidly. Vitamin C has many immune boosting properties, but is distinctively beneficial for individuals with seasonal discomfort because of its ability to deactivate histamine.
