Works for allergies if you take consistently
These were recommended by my Naturopath for my allergies. Previously I was using Benadryl and Claritin (generics). I kept trying to get off the over the counter anti-histamines due to having several side effects and finally I discovered these. I take four or five a day and keep them handy. They work best if you anticipate and don’t wait until you’re miserable. I have been taking these for about a month in heavy allergy season and haven’t had an antihistamine since. On really heavy pollen days I supplement with a nasal spray but I prefer that to popping the OTC pills with all their side effects so I’m making it work.

Working great for my MCAS. This has NO CORN.
I have MCAS and am super sensitive to a bunch of stuff. I am also allergic to corn, so that makes getting supplements more difficult. There’s NO CORN in this!It has definitely contributed to a huge improvement in my quality of life with MCAS.I have had no side effects other than yellowish poop (it’s to be expected if you consume flavonoids like this – this is a pretty pigmented one, similar to how turmeric is), and I trust this brand to have high quality product. I’ve always had good luck with this brand.I really can’t imagine my life without quercetin, it’s given me so much symptom improvement. Every time I have to stop for testing of some kind, I’m counting the minutes until I can start taking it again.Oh and this stuff doesn’t smell bad. I have been through a few brands and some of them I’ve had to quit because they started smelling awful. This one has not had that problem at all!
