Everyone's body responds differently. With an inflamitory diet, the benefits might be minimal. But if your already avoiding the foods that make ur immune system mad, this product does s pretty good job of reducing histamine levels that can drive u mad. **Q: does this product have pork or porcine as an ingredient?** A: It contains "Diamine Oxidase (from porcine kidney protein concentrate) 20,000 HDU". The label also states "60 Vegetarian Capsules". "Does not contain: Wheat, gluten, corn protein, yeast, soy, dairy products, fish, shellfish, peanuts, tree nuts, egg, artificial colors, artificial sweeteners, or preservatives." **Q: Hi, how can you say your caspules are vegetarian if the contents are made out of pig's kidney?** A: Technically it does not contain pork. It contains an enzyme found in pig kidneys. I wouldn't call that pork. There are no allergy causing proteins from pigs in the capsule. It should be a safe product for anyone with pork allergies. On a religious basis I don't have an answer. **Q: Why does this product contain so many toxic fillers (shellac(!), polyvinylpolpyrrolidone, titanium dioxide)?** A: The titanium dioxide appears to be a mistake on the safety info above. The actual product label from the maker's website does not list titanium dioxide. http://www.seekinghealth.com/histamine-block-seeking-health.html ## Customer Reviews ### ⭐ Check when you first receive…. *by B***. on 12 August 2023* ### ⭐⭐⭐⭐⭐ This is the one! *by J***N on 21 March 2026* ### ⭐⭐⭐⭐ Small but noticeable difference with my non IgE mediated soy allergy when eating out. *by D***E on 26 October 2025* ## Frequently Bought Together - Seeking Health Histamine Digest - Formerly Histamine Block, DAO Enzyme Supplement for Histamine Food Intolerance, Supports Digestive Health, Upset Stomach, Vegetarian (30 Capsules)* - Seeking Health ProBiota HistaminX, 10 Billion CFU Low-Histamine Probiotic Supplement for Gut Health, Microbiome Balance, Digestive Comfort for Histamine Intolerance, Vegan & Vegetarian (60 Capsules) - Pure Encapsulations Magnesium (Glycinate) - Supplement to Support Stress Relief, Sleep, Heart Health, Nerves, Muscles, and Metabolism* - with Magnesium Glycinate - 90 Capsules --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/723624706-histamine-block-provides-20-000-hdu-of-diamine-oxidase-ascorbic](https://www.desertcart.hr/products/723624706-histamine-block-provides-20-000-hdu-of-diamine-oxidase-ascorbic) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-23*
