Why Dr. Ruscio, DC Recommends it
- The synergistic blend of ingredients in Histamine Pro helps balance the immune response when the immune system is challenged.
Tinofend® is a superior form of Tinospora cordifolia extract with a guaranteed level of active ingredients (polysaccharides) to support immune health and histamine levels.
Supplies 600 mg quercetin (some products have less than effective amounts).
I recommend using Histamine Pro alongside a gut-healing diet and probiotics, as leaky gut and gut bacterial imbalance can underlie histamine intolerance.
What the Research Shows
- In a randomized controlled trial in subjects with hay fever, Tinofend® stimulated the activity of white blood cells that regulate immune response and reduced the number of eosinophils (immune cells which release histamine). 83% patients obtained complete relief from sneezing, 69% from nasal discharge, and 61% from blocked nose [1].
In cell studies, quercetin stabilizes mast cells that release histamine (the principal cause of reactions to pollen and other allergies) [2] .
Quercetin plant extracts may be better at inhibiting the proinflammatory cytokine IL-8 (stimulated by histamine) than the anti-allergic drug disodium cromoglycate [2].
Vitamin C has also been shown to reduce serum histamine levels [3]
In an animal study, nettle extract reduced allergic inflammation in the lungs of animals who were exposed to an asthma-causing allergen [4].
Histamine intolerance and IBS symptoms / causes overlap, indicating that bacterial overgrowth may be a cause for both conditions [5, 6, 7, 8].
Research suggests that probiotics lower histamine levels in the digestive tract, so Histamine Pro is always best taken with a probiotic [9].
How to Use it
For histamine intolerance
Useful if you react to histamine-rich foods or have trouble breaking down histamine.
To balance the immune system
May Modulate white blood cell balance and mast cell activation so your body becomes a less inflammatory environment.
For seasonal allergies
Can help if you have hayfever / pollen allergy symptoms, or other allergic reactions.
Frequently Asked Questions
Would it be useful to take Histamine Pro before the hayfever season starts?
If you know you are allergic to specific seasonal pollens, it would likely be helpful to start taking Histamine Pro for 4–6 weeks in advance of the season. But quicker results may also be experienced.
Can it be used for intolerance to histamines in food?
Yes, the supplement can be very helpful if you react to histamine in foods. A reduced histamine diet and a gut healing regime is the first priority, given that histamine issues normally start because of problems in the digestive tract.
Can Histamine Pro help with brain fog?
Yes, if the brain fog is related to histamine intolerance. Other common symptoms of histamine intolerance include migraines, nasal congestion, nausea, fatigue and hives.
What other steps should I take to lower histamine?
Dr Ruscio suggests a low histamine diet and use of triple therapy probiotics. High histamine foods include fermented or aged foods like mature cheese and wine. Certain vegetables, including spinach and eggplant, also have high histamine levels.
