Perfect for allergies
Why did you pick this product vs others?: I can definitely tell the difference, they've been a life saver and nice to have instead of constantly taking allergy pills.

Block Histamine
I have developed allergies to wheat, dairy and egg white. I am doing my very best to stay away from these foods. On occasion I do not pick up that a food contains what I can’t eat. Quite often it may say artificial flavors or colors. I did not realize I would react to these. I purchased the Histamine Block to help me when I slipped up. Unfortunately they don’t work for me.

I am shocked that this stuff works
I have a science background and am very skeptical of any and all unproven claims. But because of a year long bout of chronic urticaria (itching) all over my body I was desperate to try anything. Now this is not a miracle cure, but it did seem to reduce the itching significantly. I still need to take anti-histamines, but this seem to make the itching better.

Works but short lived
When allergies are something that you live with, finding an all natural remedy is tough to find. This product is a natural means of achieving that end. It sure beats drugs that may be harmful to you. This product uses Quercetin Dihydrate and Stinging Nettle as its base ingredients. I've heard of the values of Stinging Nettle but not Quercetin. But whatever it is, the two of them do work together pretty well. Unfortunately, for my needs, it is short lived. It lasts maybe 4 hours or so. Based on the instructions on the bottle you take two tablets daily on an empty stomach. This is an easy thing to do. But, when my allergy persists most of the day it just does not provide the protection that I need. I did try it over the term of a week thinking that it might be something that builds over time, but it was not to be. So my search continues. Comes in a double sealed bottle with 60 servings, which is good enough for a 30 day month. Easy to swallow and has little to no real taste. If your allergy needs are not over demanding this is something that might be an option as the stuff does work and it can be felt that you have recieved relief. This is a review on my personal response to the product and yours may vary. It seems to be a good product, if a bit pricy though, and is worth a try if you want to wean yourself off of the drug laden products.

Was hoping this would help my kid and me, not sure yet.
I was hoping this would help my kid and me but l am not sure yet. We are still sneezing and have runny noses due to year round allergies. We still have sun allergies too.

Incredible relief!
Noticed changes the first day. And really was relieved from the pressure build up and allergies i was having. Highly recommend trying. My nasal passage ways open up. Really wished I'd tried to resolve this earlier in life and not just live with it and bear it.

Works better than my current allergy medicine
I have severe allergies. I have prescription meds and Benadryl. These capsules work so much better and without drowsiness. I highly recommend them. You will be glad you tried them. You won’t go back to regular allergy medicine.
