What ingredients are in Natural D-Hist capsules?

  • Stinging nettles leaf is used for several reasons: it contains quercetin and other flavonoids that promote healthy cells, and also has pain-relieving and anti-inflammatory properties that may lessen the symptoms of common allergies.
  • Bromelain is an enzyme found in pineapples. It contains anti-inflammatory properties and may help reduce sinus inflammation.
  • N-acetyl-cysteine is used as a mucolytic agent that helps it dissolve the thick mucus that contributes to stuffy noses, promoting clear breathing and decongestion.
  • Quercetin dehydrate is the form of quercetin that's absorbed most efficiently by your body. Quercetin is a flavonoid found in red wine and other foods. As a flavonoid, it protects your body's cells from free radicals and oxidation. Quercetin also acts as an anti-inflammatory, decreasing allergy symptoms by blocking your body's production of histamine. Histamine is a natural chemical produced in response to certain stimuli. It produces allergic reactions such as sneezing, nasal congestion, and itchy skin. Many classic antihistamines tend to make you sleepy.
  • Vitamin C is used for so many purposes in the body, and one of the most well known functions is its believed ability to reduce symptoms of the common cold.
