Nature's SunshineHistaBlock | 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.

I decided to use this product because it has been very effective over the past few years for me. My body became tolerant to name brand antihistamines and they were no longer effective for me. The fact that this antihistamine is made from herbal ingredients is also a reason why I choose to use HistaBlock.

This product is phenomenal! After years of taking Claritin-D for my indoor and outdoor allergies, I finally found something that completely eliminates all symptoms, including stuff or runny nose, burning, itchy eyes, coughing, excessive mucus which left my nose raw from boxes of Kleenex. So grateful as I truly feel this product has improved my quality of life.

I purchased this to help with my histamine flare-ups. My rashes/hives have improved somewhat but I have no idea if it's from this. I've been cutting out foods that trigger a lot of histamine in addition to taking this supplement. The capsules are fairly easy to swallow and I haven't had any issues after taking them for over a month.

Great! Relieved my breathing after 8 years of suffering

The media could not be loaded. I use these when I have any type of problems with my lungs. I have gotten myself in trouble before breathing in mold and dust. I take these to help get my lungs back to normal. Only brand I will buy! :D

Doesn’t work as well as other products I’ve used.

I have used this for many years it is especially helpful during pollen season.
