This Source Naturals of quercetin has strong formula composed of active substance 1 capsule 1 g of quercetin, almost 2 times higher than other manufacturers of such supplements. Previously, I took quercetin by Now Foods, it is also a good structure, but it had to take 2 cap. 3 times a day. So I decided to test this Activated Quercetin. With the dosage I have not yet fully defined, but the feelings, I think that still will have to take it as well to 2. 3 times a day. The conclusion is, why pay more may come back to quercetin with bromelain from Now. Quercetin is a naturally bioflanoidom combined with bromelain (from pineapple hood), has anti-inflammatory, antihistaminic property.

I recommend to all who have an allergic or vasomotor rhinitis and nasal mucosa swells at various stimuli, such as poor environmental conditions, house dust, allergies and headaches.

I've been using quercetin for lowering my pollinosis symptoms.This one is the second I've tried so far.It works as expected: less irritation from blooming plants, less sensitivity to house dust.Great dosage for that price.The only thing I find disappointing is the size of the tablets which are pretty challenging to swallow. Won't recommend to elder people.Will definitely buy it again.

This is a great supplement, especially for allergies. Allergy medicine, such as benadryl or citirizine, blocks histamine receptors. Quercetin reduces histamine production, giving it a synergistic effect with allergy medicine at reducing allergies. Bromelain and Vitamin C both improve absorption of Quercetin, in addition to their own benefits. This is close to the perfect single supplement for allergies. It would be improved with the addition of Silymarin (a component of Milk Thistle). Silymarin promotes optimal function, and also stimulates regeneration, of both the liver and kidneys. The liver is the primary filtration system of the body, to include removing histamine from the blood. By optimizing liver function, Silymarin improves the rate at which the liver ...

It could also be improved with the addition of Cat's Claw (a tropical vine), which inhibits production of the inflammatory cytokine TNFa, one of the major results of histamine.All of this that I have said is concerning the anti-allergy benefits, and does not include the myriad of other benefits from the components in the supplement nor that I have listed here. For instance, Vitamin C has more than 200 functions in the human body. They called this activated quercetin, and indeed this supplement does a phenomenal job at getting the most of it into your body.

I've developed ashtma last January 2022 after getting covid double vaccinated last December 2021 (got really really sick after 2nd shot) breathing was hard in some days and exercising to get back on track wasn't easy with the breathing issues. After taking Quercetin + NCA for 2 weeks I've noticed I haven't used the inhaler given to me by doctor, I am not losing my breath often and don't get easily tired climbing stairs. There is also extra energy found in me and I've noticed my nose doesn't get irritated by pollutants to start the asthma episodes. It's been great help to manage my breathing problem. I followed the recommended usage at the back. Great product, I'll definitely order again.
