This did well for me. the during this allergy season. I didn’t take Flonase or Allegra. Everyone at work was sick as a dog due to spring allergies but me. I skipped a few days during a rainy spell then I got some moderate allergy symptoms but nothing like my coworkers who had to call out sick; so I say be persistent with it and don’t miss any days of taking.

You may be looking at these reviews because you came across something mentioning a current study being done on quercetin and Covid 19? Or possibly you read about the study done years ago that showed quercetin is a promising agent against SARS, which is a coronavirus very similar to Covid 19? Honestly, the theory behind it is very promising, and quercetin is just one of MANY flavanoids that show promise in preventing Covid 19 from infiltrating lung cells, another is dihidromyricetin, which is similar in structure to quercetin. You can look up the studies involving these compounds in Pubmed, just search for quercetin + coronavirus. While you’re at it, look up the research being done on nicotine and Covid 19, it’s fascinating. Covid 19 is primarily destroying lung tissue through “cytokine storms.” Well, we’ve known for a LONG time that nicotine has a major influence on cytokine storms (which are common in autoimmune diseases), there are even studies that show a benefit from taking nicotine with rheumatoid arthritis for this very effect. I’m not a smoker and I would not start just to gain this benefit, but I would consider taking nicotine through a low dose patch or through gum the SECOND I think I’ve caught Covid 19. In the meantime, I am taking 1,000 mg of quercetin per day and I will until we get a working vaccine. I recommend stocking up because a LOT of people have caught on to this outstanding supplement, and this is my very favorite brand. Smell it when you first open it up, it smells delicious. Good luck and good health to you all!
