I have heard that it is an excellent body booster. I have not finished it yet and I do not have a personal opinion.

Although I bought it while my spring allergies had already started, I can say that it helped to a good extent... Next year, I will start using it earlier.

I am still on the first bottle, so far so good, after 25 years of antihistamines, I will come back.

For anyone who understands... https://c19quercetin.com/meta.html we are talking about META-ANALYSIS... in the field of prevention... statistically significant! Just so we don't forget...

I don't know if I have an intolerance to keratin or any other ingredient, but it caused me intense nausea. I can say that it caused me a problem. Every pill and bloating in the intestine. Unacceptable. I would try keratin but not with this complex, as I can't know what really bothers me. But this particular one, never again. Trash for now.

Quercetin truly works wonders for Rhinitis without burdening you with chemical medications. It completely stops the symptoms for me during the spring season. In the past 5 years, I have tried 5 different products with Quercetin for Allergic Rhinitis. This one from Solgar is the most effective of all in my body and relatively affordable.

I lived for years with antihistamines.... Especially during the Spring months but also throughout the year. With all the related side effects, drowsiness, headache, fatigue, etc... In an alternative pharmacy, I asked for something for allergies, probably by chance. I didn't believe that there was anything better than the related medications and I hadn't heard anything about quercetin. I simply got cured! I didn't take antihistamines again and I don't think I will again. With just one capsule of quercetin per day, 500mg!.. No side effects and a feeling of euphoria!...

My cousin recommended me this product, which she has been using for years and is very satisfied with. I started taking it in early March and I take two capsules a day, morning and night after meals. I really saw results, I am not bothered by sneezing, stuffy nose, and coughing, without taking any other medication. It is a very good alternative for seasonal allergies and for those who want to avoid traditional antihistamines with their known side effects. I will definitely take it every year before the start of spring.

The best product in terms of its active ingredient (quercetin). It had an effect on my wife after one week (so be patient regarding its effectiveness). Use it just before allergies start (as a protective shield), strengthen the immune system, and improve athletic performance.
