- Powerful Histamine Support with Natural DAO Enzyme – OmneDiem Histamine Digest provides 30,000 HDU of Diamine Oxidase (DAO) per serving, a crucial enzyme responsible for breaking down histamine in the gut. This high-potency formula helps individuals with histamine intolerance enjoy a wider variety of foods without unwanted reactions. By targeting histamine directly in the digestive tract, it reduces symptoms like flushing, bloating, nasal congestion, and headaches caused by histamine-rich foods, promoting overall digestive and immune health.
- Combat Histamine Sensitivity & Enhance Digestion – Designed for those sensitive to histamine, OmneDiem Histamine Digest helps mitigate histamine-induced discomfort before it starts. DAO works by degrading excess histamine from food, preventing it from triggering adverse reactions. Whether you're sensitive to aged cheeses, fermented foods, red wine, or cured meats, this supplement provides essential support to ease gastric distress, inflammation, and other histamine-related symptoms, ensuring greater meal tolerance.
- Fast-Acting Formula for Immediate Relief – Unlike general digestive enzymes, DAO targets histamine degradation at the source, working within 20 minutes of ingestion. Simply take it before consuming histamine-rich foods to help prevent symptoms like stomach pain, itching, dizziness, or skin reactions. The rapid-release vegetarian capsules ensure quick absorption, making it an effective tool for maintaining digestive balance, supporting gut health, and improving food tolerance in those with histamine intolerance.
- Non-Systemic & Clinically Proven for Safety – OmneDiem Histamine Digest is formulated with clinically tested DAO, acting exclusively in the digestive tract without affecting overall histamine levels in the body. Unlike antihistamines, which block histamine receptors, DAO naturally breaks down histamine without entering the bloodstream. This non-systemic, side-effect-free approach makes it a safe and reliable solution for daily histamine intolerance management, improving overall gut function and well-being.
- Supports a Balanced Diet & Quality of Life – Histamine intolerance can limit food choices and impact daily comfort, but OmneDiem Histamine Digest allows for greater dietary freedom. By reducing histamine overload, it helps alleviate common symptoms such as flushing, nasal congestion, digestive disturbances, and skin reactions, allowing you to enjoy meals without worry. Whether you’re dining out or following a histamine-restricted diet, this DAO supplement provides the digestive support needed for optimal health and well-being.
