All Natural Antihistamine Supplement, Compare to Natural D-Hist, Histamine Blocker, Hist Guard, Works for Pollen, Pet Dander, Dust, Mold, and Odor Allergies. 120 Capsules

Very helpful for my husband‘s allergies so he doesn’t have to take Benadryl every day. Sneezing and runny nose at a very minimum with natural help aid.

Natural probiotics and they work great. No issues and easy to take daily.

I have been using Dhist for years as a natural treatment for allergies. Dhist is expensive , and at times difficult to find even on Amazon. I decided to try this generic equivalent and have been pleasantly surprised at how well it works . I love the savings for the same result. I use one capsule daily for maintenance together with a daily zyrtec. I gear the Histamine Shield up up when pollen counts get me sneezing. If you start this product in the midst of an allergy attack you will likely need up to 6 capsules for a few days, and the taper it down. This capsule contains vitamin C, bromelain that reduces swelling, quercetin that is an antihisstamine, nettle leaf a natural treamtent for allergies, N-Acetyl-L-cystein that thins mucus. This product keeps me from having to use flonase. I do not like using steroid products like flonase for my allergies as i dislike the smell and nose bleeds I get.

I tell everyone I know about this stuff. I live in Austin Texas where we have endless sunshine and warmth at the cost of horrific year round allergies. I used to take allergy meds that made me drowsy and whacked out two or three times per week. I’ve now been taking Histamine Shield Plus for about a year. Two every morning religiously and I have had to bust out an allergy med ONCE in the last year. It’s legitimately life changing and I can’t recommend it enough!!

Had such high expectations for this product after reading all the reviews, as I’ve tried just about every OTC item you can think of for allergies. Nothing seems to stop my constant runny nose and eyes(and occasional sneezing.) I'm assuming it’s something environmental, as it seemed to start when we moved into this house we are living in now. I took the required dosage, did the 10 day accelerated dose, even combined it with some drops you put under your tongue, that is supposed to help with environmental allergies (mold, dust mites, dander….) nothing has helped this annoying issue :(
