Natural Seasonal Support
Stop Negotiating
With Allergy Season.
Support healthy histamine levels and breathe easier with a research-backed formula that won't leave you drowsy, foggy, or reaching for your third cup of coffee.*
The Problem
Spring Arrives. So Does the Fog.
The windows are finally open. The trees are blooming. And you're reaching for the tissue box before your feet hit the floor. Your eyes itch before your morning alarm finishes its job. By noon, your sinuses feel like they're packed with wet cement.
So you reach for the Zyrtec. Or the Claritin. Or the Benadryl. And the symptoms quiet down, but so does the rest of you. The brain fog rolls in. The dry mouth. The feeling of moving through the day at 70% while everyone else is running at full speed.
Here's the thing most people never hear: there are other ways to support your body's response to seasonal triggers. Not by blocking histamine receptors with sedating compounds, but by supporting the balance your immune system is trying to maintain in the first place.*
The Shift
What Changes When Your Body Gets the Right Support
Without Support
Wake up congested, eyes itching before you make it to the bathroom
Pop an antihistamine. Lose the sneezing. Gain the brain fog.
Avoid the outdoors during peak season. Cancel the hike. Close the windows.
Rely on meds that dry you out and leave you feeling flat
With Quercetin Nettle+
Wake up and breathe. Not perfectly. But noticeably better.*
Support your body's histamine balance without sedation or brain fog*
Open the windows. Take the walk. Enjoy the season you've been hiding from.*

Frequently Asked
Quercetin Nettle+ is a dietary supplement, not a drug. It supports healthy histamine levels and a balanced immune response rather than blocking histamine receptors the way OTC antihistamines like Zyrtec, Claritin, or Benadryl do. It is non-drowsy and non-habit forming. It is designed to complement your existing wellness routine and should not replace prescription or over-the-counter allergy medication without consulting your healthcare provider.
Take three to six tablets daily as a dietary supplement. Many people take three tablets during milder days and increase to six during peak pollen season. For best results, divide the dose across the day. Consult your healthcare provider for personalized guidance.
Yes. The Quercetin Nettle+ formula is based on research published by the National University of Natural Medicine in Portland, Oregon, showing support for seasonal conditions. Individual ingredients, including quercetin, freeze-dried stinging nettle leaf, and bromelain, each have published clinical and preclinical data supporting their roles in immune modulation and histamine balance.
Quercetin Nettle+ is a dietary supplement. While many people use it alongside their existing allergy routine, you should always talk with your healthcare provider before combining any supplement with prescription or over-the-counter medications.
Yes. Quercetin Nettle+ contains no GMOs, soy, yeast, gluten, dairy, milk or egg products, sugar, starch, or preservatives. The tablets are vegetarian. Other ingredients include cellulose, organic rice concentrate, rice extract, and palm kernel extract.

I have been taking these for almost a month now and already feel healthier and have more energy. This vitamin in particular has everything we need for men in our 50’s. 60 pills per bottle 2 a day = 30 day supply for $56 to $57. I believe they are a bit pricy but well worth it
This supplement is exactly what I was looking for for my son. It tastes good and provides him with the nutrients we were looking for without synthetic ingredients. Great customer service as well. Thank you!
I have been using the blood sugar support for about two weeks now. I have been type two diabetic since 2018.
I have seen a noticeable decline in high blood sugars. With our hot weather this summer I did have some ice cream a couple days in a row and I noticed that my blood sugar still stayed within a healthy range. I can’t guarantee that for everyone, but it did help me.
I had multiple surgeries on my sinuses. I was told that I would have to be on steroids the rest of my life, as the surgeries did not correct the problem. Mt Angel Quercetin Nettle+ has completed cured all my sinus issues! I recommended it to all who struggle seasonal or otherwise.
