I started taking this immune boosting supplement (along with some others) to improve my health before I contracted covid-19. Since I am middle age, I figured I need all the help I can get! When I did contract covid, I only had cold symptoms and a shallow cough that didn't last very long.

This is an exceptional high quality supplement for seasonal allergies and also something you want to have on hand for any colds that involve nasal stuff! Every year when the acacia trees in our area bloom my husband is a sneezy, nose runny, eye watery disaster and this does the trick for him every time! Throw away that Claratin bottle and swap it out with this NON drug that actually works with your immune system and doesn't suppress it. Simple but oh so helpful ingredients are all you need here!

I have been using different brands of Quercetin since all this covid business as a way of assisting the zinc supplement I also take to enter my cells. My understanding is that quercetin is required for this task. I'm not sure I notice anything in particular with the way my body feels. I use this product more as a way of boosting my immune system in combination with zinc. I feel the product is of a good quality and I look for products which contain ingredients which I'm willing to put into my body. No complaints with the packaging.

I love this form of quercetin and like to keep all supplements food based. I always keep these on hand and take often - keeps up immune system and holds allergies away.

I give this mainly to my Maine Coon cat who was getting ulcers on her lips & since adding a bit to her meals she is 100% Really good natural antihistamine for humans too, lol!

This is one of the best products for allergies. I like it because it is freeze dried. The combination of nettle and quercetin is even better. The quality is excellent !!!

Giving to my dog for food allergies that cause terribly inflamed, sore skin. Working really well. Must taste OK as she eats it sprinkled on her food. Good quality product, plant derived ingredient. Happy with price and delivery.

The package is not the same as it shows, I need to take it for a while and see how effective it is but so far so good

This works extremely well. It takes a couple of days to build up in the system, and once it does, it is every effective. Amazingly patent mast cell inhibitor. I did notice some muscle pain while talking but that could be a coincidence. Regardless, something to look out for.

This formula is great for allergies. I take it during ragweed season in Canada. Makes my nose and eyes less itchy. This is an amazing brand with an amazing formula.
