Quercetin by Vital Nutrients far exceeds the other brands
I started with Quercetin by Vital Nutrients and then my health food store was out so I tried another brand and let me tell you there is no way I will switch ... Quercetin by Vital Nutrients was so much better on my sensitive stomach!

Great Quality Product.
My naturopath recommended this specific supplement and brand as a part of the holistic plan I am on to support me in healing from cancer. I like it and will repurchase as needed.

Great for me because I have a histamine intolerance. I like this better than the powder form I got on Amazon which hurt my liver. I really trust vital nutrients. My naturopathic doctor introduced me to this brand

This product is a great to support your immune system. You take this in between meals. I found it has been helping me with immune support.

Not easy to find quercetin in 250mg formulation.
Good quality. Does not have an unpleasant smell or leave an after taste.
Would consider repeat purchase.
A bit pricey than other brands.
