Nature's Sunshine HistaBlock | Respiratory Support Supplement | Supports Airways & Blocks Irritants | Antioxidant Strength | Seasonal Allergy Help | Natural Respiratory Function Aid 90 Capsules

Powerhouses include:QuercetinNettleBromelainIt’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.

Effective no side effects. Take everyday to keep allergy symptoms under control

Works great, I’ve repurchased several times now. My seasonal allergies have been getting worse each year but taking these has made a huge difference. I’ve tried all of the other OTC options and they stop working for me at some point or have side effects. Very impressed by this product!

Perfect blend that mellows my sensitivities to allergens. Love this product.

Good product.Wish it could come a little quicker, but reasonable. Just plan ahead so you don't run out.

It seems to help, my allergies aren’t completely gone but this does seem to help.

Great product for allergies!!!

I got quick relief from Histablock which was good. I was coming off Zyrtec and experiencing strong withdrawal symptoms along with high histamine intolerance. However, for me, the relief lasted about 2.5 hours so it wasn’t going the distance like some other supplements I was using. It’s worth a try as everyone is different.
