Review: 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 🙌.
Review: 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.

### ⭐⭐⭐⭐⭐ Boosted immunity
*by A***! on 27 August 2023*

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
*by P***Y on 18 May 2024*

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.

### ⭐⭐⭐⭐⭐ Review
*by K***R on 23 March 2026*

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.
