- More effective immune support: Our quercetin-bromelain supplement contains 500mg natural quercetin, providing 2x more powerful immune support than other supplements’ 250mg of synthetic quercetin. Plus, we blend in 5 added ingredients for broad-spectrum support.
- Potent Zinc form: Our synergistic Z-Pass complex combines 50mg zinc with quercetin 500mg. Quercetin helps zinc pass through lipid membranes for increased absorption. Our quercetin with zinc citrate is more bioavailable than zinc sulfate: its optimal dosage is 5x more potent than 10mg formulas.
- Better quercetin absorption: On its own, quercetin isn’t easily absorbed. To combat this, we combine quercetin with 500mg of the purest vitamin C form (ascorbic acid) and natural bromelain (from pineapple). Together, these nutrients boost uptake of quercetin's polyphenols and flavonoid compounds.
- Nutrients from nature: Elderberry is rich in bioflavonoids like anthocyanins, powerful antioxidants that help defend cells by fighting free radicals. To maintain key mineral levels, we also include Vitamin D3—it’s more potent than the vitamin D2 used in other formulas.
- Vegan formula with no nasties: Our vegan complex contains no gluten, sugar, wheat, gelatin, or artificial colors. It’s also recognized by GMP standards. And, unlike other brands’ chewable tablets, our quercetin blend comes in easy to swallow capsules with no nasty odors or aftertaste.

So far I haven’t been sick.
I bought this product because my father saw something on the internet from a Canadian physician saying that if you took this product the chances of you getting sick with covid was slim. I figured it couldn’t hurt trying it since it’s vitamins. The daily dosage is 4 capsules per day. They are moderate in size. I gave an average rating on easy to swallow because it seems like the older I become the harder it is for me to swallow medicine. There really is no flavor but there is a green dust within the bottle that will sometimes coat the capsules. (I think this is probably the vitamin itself within the capsules. The bottle gives you a months supply so it’s not bad to me for the value. Vitamins in general can be a little pricey.

Great! I’ve been ordering it for some time now!
I know this makes a difference to my immunity system. Recently I was with my grandchildren who were all coming down with colds or flu. They are not very good about covering their mouths when they cough or sneeze – so germs were swirling all around me. I’m doing just fine. Well, worth keeping this up!
