If You Have Allergies - These Are AMAZING!!
I bought a duvet that I thought was down only then found out it was a down and feathers duvet. I am highly allergic to feathers, cats and dust. It bring on my asthma plus flu like symptoms. I lived with this for over a month and then decided that I would find a natural remedy because I don’t take antihistamines anymore due to reading the inserts and see the side effects. plus I couldn’t take the duvet back having opened it. Every time I did some research this came up at the first suggestion for natural allergy relief. Instead I tried spirulina which worked for 30mins once. I then took a chance on this because I just didn’t believe that it could make a difference. Wow... Was I wrong! This is AMAZING!! All of my allergies stopped in it’s tracks. This morning I started to get a blocked nose and runny nose - remembered to take this and it stopped within 30mins. I would highly recommend this for anyone who has similar allergies. It’s insane how quickly it works. It says to take two a day but I only take one which seems to work for approx 20hrs. Can’t recommend this enough. Oh and one side effect that I’ve found from this supplement is that I have more energy. I wake up at 4am most days and normally I’m groggy... Since taking these I’m wide awake at 4am. No oversleeping for me anymore!

Helped my digestive troubles & stopped hayfever
This REALLY helped with my sensitive stomach. After a long period of stress I was having major problems with my digestion, I'd have reactions to food (crazy huge bloating, anxiety, panic, indigestion, IBS). These were foods that had never caused me any issues before. I suspected "leaky gut" Quick bit of info (from Dr Josh Axe): "Leaky gut syndrome is a condition where undigested proteins like gluten, toxins and microbes can pass into the blood stream. Another name for this condition is “intestinal permeability” which means the “tight junctions” or the gateway between the intestinal wall and bloodstream have been damaged and are allowing the undigested particles to pass through the intestinal wall. When these particles enter the bloodstream it will cause system wide inflammation and can initiate an immune response in the body" Quercetin is said to help tighten up the junctions in your intenstinal wall to stop the permeability causing the problem. I took one of these a day (lower than the suggested dose of 2) and found that I felt a lot more relaxed and did not have the food reactions. Quercetin is also a potent anti-histamine. I started getting hay fever, sneezing and itchy eyes. One of these a day kept it at bay! It needs to be taken BEFORE any reaction as it will not stop it once it's started. Unfortunately after about 2 weeks of taking it I get a tension headache that doesn't stop until I quit it. However, since I was taking it alongside bone broth, collagen and probiotics to heal my gut & digestion further I found I could cycle it on and off to still see improvement and I still found it a massive benefit to me. The capsules are average size and very easy to swallow with water. Highly recommended!

Cured post nasal drip and allergy induced dry skin pads.
WHAT IS QUERCETIN? Quercetin is a flavonoid that’s found in plant foods such as leafy greens, tomatoes, berries and broccoli. Flavonoids are powerful antioxidants that can prevent or delay some types of cell damage. ----- ----- RESEARCHED BENEFITS Quercetin is anti-viral, anti-microbial, anti-inflammatory and anti-allergic. Research shows that quercetin can: - reduce inflammation - reduce symptoms of arthritis - protect brain cells from oxidative stress - fight allergies - support heart health (reduces systolic blood pressure) - reduce pain - protect skin health - exert antibacterial activity against various types of Staphylococcus infections ----- ----- RECOMMEND DOSAGE Quercetin is typically used in the range of approximately 1000mg to 2000mg per day. ----- ----- INTERACTIONS Be careful if you are taking drugs such as antibiotics, cyclosporine or warfarin as quercetin may change how these drugs work and raise the risk of side effects. ----- ----- MY EXPERIENCE OF TAKING QUERCETIN Solgar is a much trusted brand and the capsules are easy to swallow. I've had allergy symptoms such post nasal drip and scaly skin patches for years, which I have managed by taking a daily antihistamine and monitoring my diet. I hate ingesting nasty chemicals so I thought I'd replace my daily antihistamine with quercetin. I take two quercetin a day and my post nasal drip and allergy induced skin patches has completely disappeared. I'm truly amazed at the results and highly recommend this product

I can't praise Quercetin Complex enough!!! My allergies were so bad (allergic to everything except dogs and cockroaches - really). I was on weekly shots (for years), citrizine in the morning, fexofenadine at lunch (loratadine had no effect), 3-4 times the normal dose of budesonide nasal, azelastine as needed, as well as daily guaifenesin and pseudoephedrine, plus Budesonide/formoterol inhaler for the chronic cough, and albuterol in a nebulizer. I was still miserable. Post nasal drip, constant throat clearing, sinus headaches & migraines, chronic rhinitis and frequent bronchitis. Then, the doc said I had GERD. I started reading about side effects and guess what? The OTC antihistamines CAUSE chronic cough and GERD. The omeprazole the doc wanted to put me on also has side effects - all the acid-reducing meds do. They block protein absorption which seriously limits your body's ability to heal. To top it all off, the main symptom of GERD is too LITTLE stomach acid - not too much. Adding 2 Tbsp of organic, non-GMO apple cider vinegar to my tea has helped immensely. Most docs just treat symptoms, none try to find the cause. The cause was all the pharmaceuticals they kept putting me on. Each one to treat the side effect of the last. ENOUGH! I found Quercetin when the doc put me on omeprazole. It made me sick, so I started researching. It took a few weeks for Quercetin to kick in fully, but now, I'm off all the OTC antihistamines, only use budesonide nasal occasionally, haven't touched azelastine, only use Budesonide/formoterol inhaler twice a day instead of 4x, only need the nebulizer if I get sick, and am looking for natural alternatives to the guaifenesin and pseudoephedrine. It also helps to add Similisan nasal allergy relief spray and Similisan allergy eye drops. Both are natural and don't have side effects. Now, my headaches are better, fewer migraines, less post nasal drip, less coughing, less allergies. I feel so much better! The docs and the pharmaceuticals were only making me worse. I live in Florida and I would have migraines at least a week before through a week after every hurricane that came within a few hundred miles of here because of all the pressure changes. My head is a human barometer. Every change triggers a headache and I have to hold my nose and blow like on an airplane whenever the pressure changes. When hurricane Irma came through, I had a migraine for 4 weeks!!!! This year (w/ Quercetin) we had one come close and I just had to clear my ears a few times - no hurricane migraine for the first time since we moved down here (15 yrs)!!! I can't believe the difference!!! Thank you Solgar for making this amazing product!
