Quercetin Nettle+ – Natural Seasonal Allergy & Histamine Support
If every high-pollen day has you reaching for tissues, Quercetin Nettle+ gives you a natural way to support clear sinuses, calm histamine levels, and stay ahead of seasonal flare-ups. This targeted formula combines quercetin, freeze-dried stinging nettle leaf, bromelain, vitamin C, vitamin B5, and magnesium to support a healthy immune and inflammatory response during allergy season.*
Quercetin Nettle+ is based on research from the National University of Natural Medicine in Portland, Oregon and is designed for people who want serious seasonal support without feeling foggy or wired.* To learn more about the thinking behind this formula, visit our Quercetin Nettle+ fast-acting seasonal support overview .

How this natural allergy-support formula works*
Quercetin – plant-powered histamine and allergy support*
Quercetin is a flavonoid found in onions, apples, and berries. Lab and clinical research suggests that quercetin can help reduce histamine release and modulate key inflammatory mediators involved in allergic responses, including seasonal allergic rhinitis.* For a deeper dive into quercetin science, see this review on quercetin and allergic diseases and this trial on quercetin-containing supplements and seasonal allergy symptoms .
Freeze‑dried Stinging Nettle Leaf – traditional herb with modern data*
Freeze‑dried stinging nettle leaf has a long history in herbal medicine for seasonal symptoms and upper respiratory comfort. In clinical work with freeze‑dried nettle, many participants reported improvement in hay fever symptoms, and some found it comparable to their usual allergy medication routines.* You can read more in our own Quercetin Nettle+ seasonal support article and a modern review of stinging nettle’s anti‑allergic activity .
Vitamin C & Magnesium – immune and histamine metabolism support*
Quercetin Nettle+ uses buffered vitamin C (magnesium ascorbate plus ascorbic acid) to support immune function and healthy histamine breakdown.* Vitamin C has been studied for its role in histamine metabolism and immune defense, which is why it is a core part of our quercetin and immune health education .
Bromelain – enzyme support for sinuses and airways*
Bromelain is an enzyme derived from pineapple that has been studied for its ability to support a healthy inflammatory response and promote sinus comfort.* It is included here to complement quercetin and nettle, especially during high‑pollen months.
Vitamin B5 (D‑Calcium Pantothenate) – supports stress and energy metabolism*
Allergy season can be taxing. Vitamin B5 supports normal energy metabolism and helps the body respond to everyday stress so you are not running on empty while your immune system is working.*
For people who want a natural option in their allergy toolkit*
Many people lean on over‑the‑counter antihistamines such as loratadine (Claritin), cetirizine (Zyrtec), or diphenhydramine (Benadryl) when allergy symptoms spike. Quercetin Nettle+ is different. It is a dietary supplement, not a drug. It is designed to:
- Support healthy histamine levels and a balanced immune response*
- Help maintain clear nasal and sinus passages*
- Pair well with a broader wellness plan that may include lifestyle changes and, when appropriate, guidance from your clinician*
It is not intended to replace prescription or over‑the‑counter allergy medication. Always talk with your healthcare provider before changing how you manage allergies or sinus issues.
