Heavy metal detox
I love the product Heavy metal detox. I got a blood test and it showed I had a lot of heavy metals in my blood. So I have been using it every day. And the last blood test showed a marked improvement. I will continue to use it. It really works!

I've found HistaBlock helpful in controlling spring allergies. i prefer taking natural herbal products to over-the-counter products at the drug store.

The over the counter allergy medicine would make me feel tired and sleepy. I’m so glad I found this alternative. It works with in the hour for me and doesn’t make me drowsy. Great product!

This Stuff Works!
I was recommended a sister product to the Histablock over 10 years ago. When I went to reorder for this year, I saw a product called Histablock and decided to add it to my order to see if it worked. The short answer is YES! It works! The longer answer is that the Seasomal Allergy supplement (Formerly ALJ) worked well on its own, but never really broke up thr nasal congestion, in my opinion. The Histablock does break up the congestion. Since taking the Histablock my sinuses are much clearer and I am not nearly as congested as before. I feel it has improved my ability to breath through my nose and kept my airways clear. Would I recommend this product? Yes. Without hesitation. It works.
