Adrenal Fatigue
During pollen season my allergies get so bad I finally did some research and came across histablock. I take it in the evening at bedtime and so far this has improved my allergies and my asthma.

Hard to tell
I could not tell if they help me or not. I had to quit using them because they gave me digestive issues. However I gave them to my daughter who has allergies to her dogs . I hope they help her

Great Product!
HistaBlock has been a game changer for some of us with allergies. I used to take 2-3 other supplements for allergies,but found this one does a better job preventing allergy symptoms (itching, watery eyes, sneezing). I highly recommend it!
