Rated 5 out of 5 by from Great for energy I did a lot of research before I bought this product. I usually get very tired in the afternoon at work. I take 1 pill after lunch and usually feel much better. I tried stopping and could really feel the difference. My son and I both take it religiously.

Rated 5 out of 5 by from This product gives me endurance. I exercise a little over 2 hours a day. Not all at once but at different times that add up to a little over 2 hours and this supplement gives me the energy needed to get through my days. I recommend this supplement.

Rated 5 out of 5 by from It's Quercetin I tried a different brand of Quercetin this one came with proper made capsules, they didn't look damaged like the other brand. I just wish the capsule wouldn't contain rice so because of that I ended up removing the capsule and put it in a blend mix.

Rated 5 out of 5 by from Now my favorite quercetin supplement! Yes, a high-potency quercetin formula. I take it year-around for its multiple health benefits. I used to take a significantly smaller dose of quercetin mixed with bromelain, which was also wonderful, but I think between the 2 of them, this is the one I'd pick. 1 bottle at the suggested dose would last 1-2 months, whether or not you take one or two a day. Quercetin must be expensive to make, or is rare, because it is fairly pricey anywhere. Swansons has some of the lowest prices on it, I believe. Bottom line: If you can safely take high-potency quercetin, and you know what it is for, then here is an option for you. I am personally happy with this purchase.
