I got this per recommendation from friends for natural allergy relief and I think it helped me a lot. This year’s allergy was worst in years (I’m in Midwest). Normally my allergy turns into upper respiratory infections at least one per year but I didn’t experience that! I will continue to take this!

I wanted a quercetin product with around 500mg's. When I saw this product had 750, it was perfect. Thank you!

Packaging is clean and nice. No side effects that I’m aware of. I am sure the vitamins are doing their job like they’re supposed to. You do have to take two pills, and they are on the larger side of capsule size (although I’m sure there’s bigger out there in vitamins).

Bought this to help boost immune system. No complaints. Seems to be working, no side effects.

Awesome supplement! Everything in one pill! And the savings $$.... Not having to buy the 4 vitamins separately is a bonus! Hubby and I both had COVID. This amazing supplement gave us the immunity needed to kick it in just a few days with very little symptoms!
