Boosted immunity
Great supplement. Allergies (nasal) vanished and no side effects. Helped me get over colds n coughs quicker. A super natural antihistamine and anti-inflammatory 🙌.

I don’t see the difference
I was taking this for my allergies and I don’t see any difference… I got on to antibiotics to reduce my allergies. But maybe a continued use of this supplement before the allergy season might help.

It works
I use it as a natural anti inflammatory. Really helps me if I feel a cough or cold coming on.

Great stuff
Ok so my histamine levels were over 7867 in highest ref range 959 /7 times the norm basically/. The bloating was one thing, but every morning I felt like I have something stuck in my throat that I desperately want to caugh out, but couldn’t. ChatGpt told me to get Quercitin and Vitamin C. I’ve heard about this brand Thorne that athletes use so even tho more expensive than other brands - I gave it a try. Long and behold the sensation in the throat IS GONE. I don’t know the histamine levels, but it is obvious this works

Real phytosome, unlike other brands
I bought this brand because it has a license from Indena S.p.A for the phytosome technology whereas most quercetin phytosomes don't and do not have the same absorption. For normal colds, this is probably overkill, but I had a persistent cough from a cold, and I also had inflammation from a slipped rib that simply wouldn't go away after a couple months. I used this since quercetin is a powerful anti-inflammatory (besides being an ionophore), and the inflammation in my ribs was completely gone in two days. Even after the first day of trying it, the pain was about 70% gone. It might be a coincidence, but I was trying all forms of exercise that didn't help. I'm not sure it helped with the cough, which went away slowly.
