its natural and it works

Best taken between meals or half an hour before a meal. This stuff works well for my allergies and overactive histamine response. Helps with my hay-fever and cat allergies and also relieves my stuffy nose if I have a cold.

Great for relieving my symptoms

This product helps with any itching and the significant fatigue I experience with histamine responses. And the effects happen almost immediately. I recommend this product to anyone who asks!

Stops Hayfever Fast
17-02-2021 15:39:21
I suffered from hay fever for years and didn't try any other natural products after a herbal tea which was meant to be a cure all for hay fever didn't work for me. I tentatively purchased Histablock recently and the first two capsules I took eliminated all of my symptoms. I usually start sneezing when I wake up but now at the first sneeze I take two capsules and I'm good for the entire day. Occaisionally I will take another two before bed. Really pleased to have found this product.

This product is a must have

This product could be great for anyone with allergies. My body produces to much histamine on a daily basis for over ten years now. I get hives, welts, rash and itching. I read up about stinging nettle and Quercetin and was amazed at the info. This product has helped me 90%. Don't get me wrong I still get my hives very mild and some days none but nothing compared to the outbreaks I have suffered with daily for years. Give it a go. Better than any product I have brought over the counter.

Histablock Worked Wonders
23-07-2020 17:35:31
Firstly I tried this product at a friends place down the line. I had severe allergies & nothing with me, within an hour the itchy eyes, sneezing & runny nose had gone. I have since given some to my grandson, who has asthma, allergies & does a lot of fitness with his chosen sport. He took Histablock an hour before training & got through 2 hours without using his primary inhaler. I definitely recommend this product to those who suffer with allergies.

Great for histamine intollerance

I bought this to help with a nasty case of histamine intolerance which has lead to hives and severe eczema. Definitely helped reduce the symptoms and probably more so than the antihistamines that my doctor gave me. I would imagine that it would help with seasonal allergies too. Highly recommended.
