Best value quercetin! I am using this as part of my cancer recovery and so far all is well. No cancer, no side effects, no chemo.

great

good supplement. I really liked the effect, I feel the benefits. The ingredients in the composition are in good shape. I was pleased with the quality of the additive, and I also liked the packaging from this manufacturer. The taste and smell are neutral. I am very pleased. I advise all my friends to try this 😍😘😊

Effective !

Really been helping with my severe seasonal allergies due to MCAS. I do notice taking it with Bromelain makes it more effective so am buying the Swanson Quercetin plus Bromelain combo next time.

Good Quality

Great experience with iHerb! The quality of the products is excellent, and I really appreciate that the ingredients are pure. The prices were quite competitive, and the packaging was a good size. The products taste great too! I’m excited to see more discounts in the future—can’t wait to place my next order!

Good Price For Strength

Recently swutched to buying Nutricost for a few items that were out of stock in my regular brand - pricing seems very reasonable, and the strength per dose is considerably higher for quite a few lines. Happy so far with this range.

Great size and price!

I started using quercetin back in 2020 when the epidemic started in combination with zinc to boost my immune system and protect from flu and colds. Quercetin is a fantastic antioxidant, highly important for optimal health and a strong immune system. Highly recommended for lowering inflammation and a strong immune system. This product also had a great price for its size and is quite high quality.

This is one of the best vitamin C supplements I've tried! The absorption is noticeably better thanks to the liposomal form, and it's very gentle on the stomach—no discomfort or acidity at all. I felt a clear boost in my immunity after just a few days of use. The antioxidant benefits are real, and I love that it's high quality with clean ingredients. The taste is surprisingly pleasant, and the individual packets are super convenient for travel. Great mg dosage and well thought-out package size. Highly recommend!

Respiratory support

Quality is excellent — capsules are well‑manufactured, clearly labeled, and contain pure quercetin extract with minimal fillers. Benefit after a few months includes reduced seasonal allergy symptoms, improved respiratory function, and enhanced overall immune support. Ingredients are straightforward: quercetin extract, capsule shell, minimal additives. Capsule size is larger — requires a solid swallow. Taste is nonexistent since the content is fully encapsulated, leaving no aftertaste.
