  • High quality supplement
I like this brand and am very happy with this product. It’s worth paying a little more for high quality and these work wonders for my health issues.

  • Amazing for people that suffer from allergies, would highly recommend
I have long suffered from allergies seasonally. Every year like clockwork September through November, and April through May, I get intense headaches, runny nose, scratchy throat, and many other symptoms associated with allergies. Sometimes my allergies are so bad that I have sneezing fits wher I sneeze for five minutes nonstop. I have always relied on over-the-counter medication‘s like Claritin and Nasonex to help me. That is until I found this. This pill works so well, and I like that I don’t have to worry about the fact that it’s a pharmaceutically, manufactured chemical, but a naturally occurring compound found in plants. By this medicine, if you suffer from allergies, I know it will help you. ... show more

  • Effective, trusted, supplement. Good quality product.
I trust Thorne products. Quercetin helps me with food allergies. If taken at night, I don't wake up congested. Zinc is also good for food allergies. I take both. I'm doing much better since being on these products.

  • The BEST!!
I started taking this because my immune system was so weak postpartum. I was catching every illness under the sun after having my baby. I was healthy maybe 3 weeks out of a 4 month period. I’ve loved other Thorne supplements, so I scoured their products in hopes of finding something that could help my immune system. THIS IS IT! When I tell you I have not been sick in months, I mean it! I’ve been taking it for 4 months now and I haven’t caught a thing. Even when my whole household would come down with something, I’d be healthy. If you’re struggling with your immune system, definitely give this a go! ... show more

  • Remedio para la alergia
Todavia estoy investigando como me funcionan. Necesito por lo menos tomarme la mitad de las pastillas para poder determinar su eficacia. Hasta ahora parecen ser efectivas.

  • Noticable effects
Been really trying to focus on my nutrition and after adding this I could honestly feel more energy, kind of hard to put it into words, but I will continue taking it.
