The Science

Histamines are part of the body's natural immune system response to help identify foreign invaders. Histamine response is triggered by unfamiliar compounds like pet dander, pollen, and dust and can also be found in certain foods. When histamines are released in the body they can stimulate further production, which causes a positive feedback loop. This can lead to increased mucus production, a runny nose, coughing, and itching. HistPro works to mitigate an excessive response with a formulation of ingredients designed to interrupt and decrease the release of histamines. Quercetin is a biologically active flavonoid and antioxidant, known for its ability to stabilize mast cells and support healthy levels of histamines.

Smaller bottle

I bought this while it was on sale to stock up. The bottle was half the size of what I normally get, so the cost was the same. I love the product just unsure what the quantity is less but price stayed the same.

Skeptical at first
