Great Alternative to Now Seasonal Rapid Relief

I was extremely disappointed when Now Brand Seasonal Rapid Relief with bioactive quercetin was discontinued! I tried taking Now Brand quercetin with bromelain, but I cannot tolerate bromelain and the quercetin was not nearly as effective as the bioactive type. So, I am glad that I found this Natural Factors EMIQ. It is as effective as the Seasonal Rapid Relief. I just wish it was less expensive. It's a much safer way to deal with seasonal allergies and histamine reactions than pharmaceuticals.

Great Quality

I deal with a lot of sinus issues and once my allergies start kicking in full gear, itchy throat, sore throat, runny nose, sneezing, nasal drip , you name it, even the headaches but that would come if I didn’t get the nasal drip under control. This stuff literally stops all of it when I take it.

Love this item. I have been taking it for occasional sensitivities a few months and it has done something amazing without taking any OTC hypersensitivity prescriptions. At the point when I initially began taking this, I required one AM and two PM. Inside around fourteen days, my sinuses cleared up and my eyes were presently not irritated and watery. I went down to one pill in the first part of the day and one PM for about a month, and presently I simply require one PM. Best sensitivity help I have found...highly suggest!

This is excellent quercetin

This is a very effective quercetin when it comes to allergies but I think Natural Factors makes one that's even better than this. I don't think you can go wrong with this one but I would recommend the LipoMicel version as being the very best. Both of them clear up my sinus passages immensely. The EMIQ version felt like my entire breathing through my nose totally opened up. It's pretty amazing! I think you just have to try them and see what works best for you. I can definitely recommend Natural Factors.

Brand I can trust

Smaller capsules with ingredient I can't find from different manufacturer. You want superiour quercetin , this is your product. Easy to swallow dapsules due to sdmaller size. Natural factors always deliver good quality supplements and this one did not dissapoint.

easy to tolerate

I’m very satisfied with the quality of this supplement. The ingredient form of bioactive quercetin is excellent and feels highly effective. The size of the bottle is practical, and the package is convenient for daily use. I’ve noticed a clear benefit, particularly in supporting immunity and overall respiratory health. This product provides strong antioxidant support and helps with balance during periods of inflammation. I’ve also observed a positive effect on general well-being and daily performance. The taste is neutral and easy to tolerate

This supplement worked better than I anticipated. Its convenient form, easy-to-follow dosing, and neutral taste make it simple to use. The effects are subtle and vary from person to person, so it’s best to consult a healthcare professional before starting.
