I was really looking forward to taking this product. Unfortunately, I seem to be allergic to it. So be careful you might be too. I am allergic to grass pollen. My allergy symptoms are: Cough, congestion, a lot of phlegm in throat. Here is the scoop: "Bromelain should not be used by people who are allergic to pineapple or to other substances that may elicit an allergic reaction in those allergic to pineapple (cross-reactivity). These substances include: grass pollen, latex, celery, fennel, carrots, wheat. Bromelain may also increase the effects of certain medications, such as antibiotics, sedatives, and anti-seizure drugs." Best wishes..
