Prevention recommended
For immunity, it is crucial! Following Dr. Murray's advice, I take Quercetin at 250 - 500 mg daily, NAC 600 mg twice a day, and Selenium. This regimen significantly aids in preventing and treating symptoms of colds and viruses. Thank you, Ayherb! Cheers to Dr. Murray!

Helps with breathing
In our challenging times, I noted this drug's inclusion in treatment protocols. I bought it for prevention, particularly during cold season with vitamin C. After taking it, I noticed a significant improvement in my breathing almost immediately. This is the best I've tried so far; I highly recommend it!

Miracle for colds
This product is excellent for treating bad colds and flu! I was incredibly pleased—after struggling with a severe flu for two weeks that didn’t respond to antibiotics, this optimised Quercetin recommended by my godmother worked wonders. I take it whenever I feel a cold coming on and haven't had a serious cold for 6 months now.

Reduces nasal swelling
It works wonders! I’ve consumed three cans, giving my child one capsule daily to alleviate nasal swelling. After suffering with adenoids for two years, using Quercetin reduced the swelling. At the first sign of a cold, I take two capsules daily.

Helps avoid illness
I am allergic to dust. This supplement aids me while cleaning at home. The capsule size is average and the dosage is appropriate. I also take quercetin along with vitamin C and zinc when I feel a cold or flu coming on. It genuinely helps me avoid getting sick.

Reliable against allergies
Wonderful! This quercetin is excellent with a good dosage from a trusted manufacturer. The medium-sized capsules are light in colour and easy to swallow. During the spring when trees bloom, I take it to combat allergies. Last year, thanks to this supplement, I had no allergies and I consistently use it for colds. Highly recommend!
