D-Hist is my ‘go-to’ product for allergy season. I like it because it’s a blend of herbs, vitamins, amino acids, and enzymes; a nice blend of Eastern and Western medicine.
How it Works
The combination of ingredients work to stabilize mast cells that cause allergy symptoms when they break open. Other benefits include thinning of mucous and opening of airway passages. Finally ingredients like Vitamin C help to deactivate histamine.
- Supports Immune Balance
- Supports Sinus and Respiratory Health
- Clears Nasal Passages
Loading Dose: 2 capsules three times per day for 7-10 days or as recommended
Maintenance: 1 or more capsules per day or as recommended
- Stinging nettles leaf
- N-acetyl cysteine
- Vitamin C
The 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.
