Quercetin, vitamin C & antioxidants
Quercetin, vitamin C and antioxidants are among the most commonly searched ingredients during pollen season, seasonal sensitivity and periods of increased histamine load. In this section, you will find products with quercetin, bromelain, vitamin C and other plant polyphenols.
This subcategory is designed for customers who prefer to choose by specific active ingredients and formula composition. These products are not intended to treat allergy, but offer a carefully selected range of supplements used in the broader context of immune function, oxidative stress and seasonal sensitivity.
Quercetin, vitamin C and antioxidants during seasonal sensitivity
In this subcategory, you will find products focused on quercetin, vitamin C, bromelain and other plant polyphenols. These ingredients are often searched for during pollen season, periods of increased sensitivity and in the broader histamine context.
Quercetin is a flavonoid naturally found in foods such as onions, apples, tea and certain herbs. In food supplements, it is often combined with bromelain, an enzyme derived from pineapple, or with vitamin C. You will find this type of combination, for example, in products from Naturtreu, while brands such as L Cell and Purovitalis work with quercetin and other polyphenols.
Vitamin C has authorised health claims in the EU. It contributes to the normal function of the immune system and to the protection of cells from oxidative stress, provided the product meets the conditions for using these claims. This is why products combining vitamin C with other ingredients used in seasonal routines naturally belong in this subcategory.
When choosing, it is worth looking not only at the name of the active ingredient, but also at the dose, processing form, ingredient combination and manufacturer transparency. With complex formulas, the individual ingredients should make sense together rather than appear as a random list of popular compounds.
