NaturesPlus Quercetin Plus with Vitamin C & Bromelain - 650 mg, 90 Vegetarian Tablets - Gluten-Free - 45 Servings

Great product and it arrived within a few days after ordering

Nutrition.

These work great. I didn't want the 250 mg per tablet so it's nice to have a 100 mg tablet that could be split if I wanted it. Works great for what I need.

It keeps my body feeling less sensitive to the air and elements.

My daughter uses this brand and gave me some to try. I like it for my immune system and it is easy to swallow.

Amazing health benefits. I take several a day when I get a cold and it helps me fight it so much faster! My miracle cure for the common cold. Also helps with any other general inflammation I have. Always feel better taking this stuff.

Product works great for immune system

I ordered this product because I was told it could help with my histamine intolerance issues. For the past week since I started taking it I haven't been able to sleep very well at all. I normally have no problems sleeping. I did some research and found this information on PubMed which is a highly reputable resource to get information about medications and supplements...The bioflavonoid quercetin is widely found in plants and exerts a large number of biological activities such as anti-hypertensive and anti-inflammatory properties. However, the effect of quercetin on the sleep-wake cycle has not been investigated. In the present study, we investigated the effect of quercetin on sleep-wake regulation. Intraperitoneal administration of quercetin (200mg/kg) significantly increased non-rapid eye movement (non-REM) sleep during dark period in rats, while it significantly decreased REM sleep. The decrease in REM sleep induced by quercetin was blocked by intracerebroventricular (i.c.v.) injection of bicuculline, a GABA(A) receptor antagonist. In contrast, the increase in non-REM sleep induced by quercetin was not affected by i.c.v. injection of bicuculline. Therefore, the present results suggest that quercetin alters the sleep-wake cycle partly through activation of GABA(A) receptors.
