“I had recently purchased your product FLAVINOX for my 12 year old son who has always suffered from allergies. For years I have been giving him allergy medicine – Claritin, Tylenol, Zyrtec – all types of medicines that didn’t really work and made him very tired and drugged out. I saw Dr Hansen on our morning news show here in Arizona as he was talking about FLAVINOX and explaining how it works and it really made sense to me. I drove over to the Scottsdale office that morning to get a bottle and went directly to my sons school to start him on these capsules.

When he came home from school about 3 hours later he was like a different person than when he left that morning. I could see it in his face and eyes. He was feeling 100% better and he told me about an hour after he took the capsule he could feel the difference and he kept feeling better as the day went on. Since then I have been giving him about 3 capsules a day and he’s a baseball player so sometimes before a game I give him an extra one and I am truly amazed at how FLAVINOX has really made a difference in his allergies. No more drowsy, drugged out state. No more sneezing 20 times in a row or constant watery eyes and runny nose. I have recommended this to everyone I talk to and know this product has been the answer for my son.”

“Thank you for your advice and wonderful supplements. The FLAVINOX is especially helpful. All three of my sons have been suffering from sinus allergies for years. After two weeks on FLAVINOX the boys no longer have any sniffling, sneezing or congestion. The FLAVINOX has stopped the sinus allergy reactions in all three of my sons—a special blessing to my 6-year-old because I was afraid that I was going to have to give away our cats to stop his allergies. The kids are most grateful. They now call you the doctor who saved our cats! Thank you!

I personally have battled skin allergies for year. After two weeks on FLAVINOX my skin cleared up completely and has stayed clear. As soon as I feel any food allergy symptoms I now take the FLAVINOX and it stops the itching without the side-effects that allergy medicines cause. Thanks so much!”

 “I sell diamonds and fine jewelry for a living. I have had allergies for years that caused so much nasal congestion that I cold hardly speak to my clients. I was embarrassed by my continual runny nose and constant sneezing. Anti-Allergy drugs didn’t help much and made me drowsy. Finally, I found Dr. Hansen’s natural allergy formula FLAVINOX , which works better than anything else I have ever taken. Taking FLAVINOX 3 caps twice a day relieved 80% of my nasal congestion and stopped my constant sneezing and runny nose without causing any drowsiness. Now I feel great.”

“I am a horse trainer and I run a Dressage Horse Training Stable. I spend most of my time outdoors every day riding horses and giving lessons. Every spring, my hayfever allergies flare up. They are horrific when the dust, the wind and the pollen combine. I have tried all of the anti-allergy drugs, including Allegra, Benadryl, Claritin, Zyrtec, etc. and they just don’t stop my eyes from itching, burning and watering. At times my allergies get so bad that I can barely see or think. But within 15 minutes of taking my first dose of FLAVINOX my hayfever symptoms completely stopped and I could see and think clearly again. FLAVINOX is simply fantastic.”

“There are so many remedies for allergies, but nothing works as well as FLAVINOX for my system. I have been a fan of this natural allergy supplement for many years. It makes me feel so good that I now take 2 capsules every morning regardless of the season.

Recently, I happened to run into a lady that works at our clubhouse that I have known for years. She was incredibly stuffed up and had red, watery allergy eyes. She looked absolutely miserable. I can’t help myself when I see people in need. So I casually told her about your natural allergy formula that I had been taking for years. Your FLAVINOX herbal allergy formula keeps all my allergy and respiratory symptoms pretty much under control without making me drowsy. I usually keep a supply with me wherever I go, but today I didn’t have any. So, I went home and came back with 12 capsules for her to try. When I saw her a few days later she looked great, even though allergy season was still in full bloom. The experiment worked. She said that she takes 3 capsules first thing in the morning and is “good to go.” She was so grateful and I was so very happy that she had actually believed me. Thank you for this wonderful formulation!”

“I work in the home inspection business and spend a lot of time outside. Every year I suffer with seasonal hay fever allergies. I have tried almost every medicine on the market. None of them seem to work very well and they make me feel drowsy and irritable, so I usually just suffer through the springtime with a drippy nose and tearing eyes that itch and sting. Fortunately, last spring, a very nice lady saw me suffering while I was working at her home. She offered to share her FLAVINOX herbal allergy formula with me. She said here take this and you’ll clear up in a few minutes. I was skeptical, but she was so nice and assuring that I said okay. Sure enough, within 15 minutes, before I had finished my inspection, my drippy nose and watery, itchy eyes had all cleared up. I had been suffering with allergies for so long that I had forgotten how good it felt to be clear headed. I will be forever grateful for the kind lady who cured my allergies by telling me about the FLAVINOX natural allergy formula.”

Vitis vinifera (Grape) seed extract contains a flavanol group similar to bioflavonoids, but distinct by being more highly water-soluble, bioavailable and electrophillic (capable of scavenging free radicals – shown to be 20 times more potent than Vitamin C and 50 times more potent than Vitamin E). The highest quality standardized Grape Seed Extract contains 98-100% polyphenols. The Catechin & Epicatechin molecules that are found in precise concentrations, either alone (monomers) or joined into dimers (2 units), trimers (3 units), tetramers (4 units), and longer polymers including tannins. Oligomeric Proanthocyanidin Complexes (OPC) include the dimers, trimers, and tetramers, the most bioactive components, but not the longer tannins. Catechin, and especially the stabilized Catechins found in the OPC concentration, reduce excessive histamine release from mast cells and prevent its production by blocking the enzyme histidine decarboxylase. OPC also inhibits the excessive production of hyaluronidase, which activates mast cell degranulation and release of histamine into the surrounding tissue.

Camelia sinensis (Green Tea) extract contains at least seven functionally active compounds including (+)-catechin (C), (+)-gallocatechin (GC), (-)-epicatechin (EC), (-)-epigallo-catechin (EGC), (-)-epicatechin gallate (ECG) and (-)-epigallo-catechin gallate (EGCG). It has been shown to possess very strong antioxidant activity against hydroxyl (OH) and superoxide (02-) free radicals, as well as lipid peroxidation. It has been shown to be many times more potent than Vitamin C or Vitamin E, to protect against Vitamin E consumption by free radicals and to chelate Iron. The Catechin in Green Tea provides functional anti-allergy activity by blocking the production of histamine via its inhibition of the enzyme histidine decarboxylase. Green Tea extract has also been fount to possess antimutagenic ((+)Catechin and (-)Epicatechin have been shown to inhibit deoxyribose (DNA) damage by reacting with hydroxyl (OH) free radicals.), antibacterial, hypocholesterolemic, antitumor and cancer preventive activities. The active Green Tea compounds were tested in vitro against each of four human tumor cells lines (MCF-7 breast carcinoma, HT-29 colon carcinoma, A-427 lung carcinoma and UACC-375 melanoma) and found to possess significant chemopreventive activity.

Quercetin is another important flavonoid. It is a potent antioxidant of its own and functions in sparing Vitamin C. It has significant anti-allergy activity through its ability to inhibit both the manufacture and release of histamine and other allergic / inflammatory agents. Quercetin also demonstrates significant antitumor activity against a wide range of cancers, including squamous cell carcinoma; leukemia; and cancers of the breast, ovaries, colon, rectum, and brain in animal and in vitro studies.

Vitamin C functions as a principal antioxidant of aqueous (water) environments in the body, both outside and inside the human cells. It is an essential nutrient that the body must consume on a daily basis to survive. Vitamin C is responsible for regenerating Vitamin E and works along with the antioxidant enzymes such as glutathione peroxidase, catalase, and superoxide dismutase. It functions as both an antioxidant to protects cells of the body and a pro-oxidant in the fight against viruses. It needs to be taken in association with flavonoids such as OPC and Quercetin for optimal function and buffering of its pro-oxidant effects.

Consistently the BEST allergy relief

I started taking Flavinox over 20 years ago when I had moved to a different state, and the seasonal allergies I encountered in the area were so bad, I didn't know if I could continue to live there! Flavinox completely took care of the problem, with no bad side effects like drowsiness or that "loopy" feeling. Now, years later, I sometimes forget that I ever had those bad allergies! They started acting up again this spring, and before you knew it, I was looking at a sinus infection. I ordered more Flavinox and as soon as I started taking it, the allergy symptoms completely went away. I LOVE this product.

Kaye Neidhardt

Works great! I take it nightly. If I forget to take it I definitely notice a difference the next day!

Allergy symptoms gone!

For years, I've dealt with seasonal allergies, and over the counter options did not help and created a host of side effects that kept me from fully functioning. Since taking Flavinox, my seasonal allergy symptoms are gone and my tolerance of other environmental allergens have improved. I love how effective the all-natural ingredients are.

Best allergy med for us

Other other allergy meds made us tired or moody. We've been using flavinox for years and love it.

This Always Works for Me and Many Others

This is amazing!!! It ALWAYS works and I will not be without it! Sometimes my nose runs badly from all the pollen around (I live in a state with many, many trees and the pollen count gets really bad sometimes) I take a couple of Flavinox capsules, and my symptoms clear up like magic! This happens to everybody I give it to! I can't say enough! It really works!
