## Overview

Nature's Sunshine Histablock is a scientifically crafted supplement combining bromelain, nettle, bitter orange, and quercetin to support healthy respiratory function. It reduces mucous membrane swelling, stabilizes mast cells, and helps keep airways open, providing natural relief from seasonal allergies and respiratory irritants. Trusted since 1980, this formula is rigorously tested for purity and consistency, making it a go-to for professionals seeking effective, clean respiratory support.

## Description

HistaBlock provides nutrients that support healthy respiratory function while the body fights against irritants, pollutants and toxins. Nettle provides well-known support from airborne seasonal substances. This formula provides antioxidant strength to help stabilize mast cells. Antioxidant quercetin has been used for its reputable respiratory system support effects. Quercetin may help stabilize cells that release compounds when exposed to irritants. Bromelain is an enzyme that acts to help reduce swelling of mucous membranes during periods of respiratory stress. The bitter orange contains synephrine, which helps the body to keep the airway open.

Review: Powerhouses include: Quercetin Nettle Bromelain It’s difficult to explain why HistaBlock has been such a key component to my health without sounding like I’m giving medical advice. But in my experience, HistaBlock has helped reduce my inflammation and allergy symptoms. Symptoms from sinus congestion to wheezing. From regular discomfort to much more serious. Regular H1 and H2 OTC antihistamines are very drying to those of us with certain autoimmune conditions. This supplement works differently (from what I recall) by helping the body not overreact to the histamine and by mucous lubrication, moving the histamine out through normal functions. Natures Sunshine is a company known for research, for thoroughly investigating the growing conditions, harvesting, procurement and transportation of each and every ingredient. And measuring consistency of each batch. I’m not with the company, but over the years have attended several free educational seminars, taught by some Medical Doctors (internists, neurologists, cardiologists), Naturopathic Doctors (who treat world-class athletes), and one of their chemists. My family has used their products since 1980. My medical doctors know which minerals, herbs, vitamins I use and approve. Only caveat is I was told not to switch brands, as my doctors read and agreed to the specific supplements. Now my immunologist is taking Quercetin, too! Some parts of the world have used the components for thousands of years. If you aren’t familiar with the ingredients, they are well-studied and if you have life-threatening (or just annoying) allergies, you should consider reading some of the research done on nettle, quercetin, orange bitter and/or bromelain. If you have question on possible allergens with this product, I’ve called them before, it was easy process to confirm that it was safe for me. (Potato starch and wheat are often in capsules- which I must avoid.) Thanks for reading this novel. I hope it is helpful, and that you find what works best for you.
