A great quality product with the extra ingredient Of Bio Quercetin makes it a great vitamin for the immune system in these trying times. I have been using the Life Extension brand for nearly a year now and have seen so many improvements in the way i feel now. At 75 years of age,I've noticed big improvements in my skin and not bruising like I used to.

I've been trying to drink this product for 10 days & the results are much better than the products. I previously consumed..I'm a new user & this is my first time buying it through HERB...The delivery was very fast, beyond my expectation.. even though the delivery was from USA to Indonesia... Life extention and Herb are the best..I don't regret it. thankyou very much..

Excellent quality and value, and this is the type of Quercetin that is best for immunity. We use Quercetin daily as part of our COVID immunity plan, and will keep on using it, as it has a long-term safety record. Forget the jabs that do more harm than good, and have no long-term studies.

Life Extension is a great quality brand. Package contains 250 tablets which are rather of a big size so you need some water to swallow. Vitamin C combined with quercetin here, so this composition provides an amazing effect for your immunity. Highly recommended in times of Covid or for recovery.

Vitamin C as a supplement is indispensable in our home throughout the winter. Quercitin is a flavonoid that improves the effectiveness of vitamin C. I'm glad I discovered this product and I can tell you that it's been a few years since I've even had a cold.

I am using this product, the bottle of 240 tablets is of good quality, so I bought a bottle of 60 tablets to give to my relatives to try. Everyone feels good reviews about the product quality, easy-to-swallow capsules and thanks for having a pretty unique product to improve resistance during the current epidemic season. I will repurchase this product. Fast delivery, securely packaged. Good.

So glad I was finally able to get my hands on this product. When I read the benefits of Quercetin and Vitamin C for fighting the symptoms of Covid and boost the immune system, I wanted to add it to my protocol. I guess everyone else had the same idea. Even beyond Covid, it's always good to keep your immune system as strong as possible, so I figured I couldn't go wrong.

This stuff was great while it lasted! I only bought one bottle to try for a while, and it really seemed to help me along. Shortly after stopping it though, (I stopped because I ran out) i started getting the sniffles, before getting sick. I am pretty sure that this stuff really helped me fight off a bad cold, until I didn’t take it anymore. good stuff! And its a nice combination!

great quality product. it really works as intended. Will definitely get more soon! Thank you so much for this. it was made of high qualiy ingredients. Plus the packaging and sizes were perfect. over all good quality. i love the smell and the taste of it. im looking forward to purchasing another one!
