Hist Diamine | Histamine Blocker | Diamine Oxidase Enzyme Formula | 20,000 HDU of DAO | Histamine Intolerance | 60 Vegetarian Capsules

Have these on hand, all the time, to take with any meals that I think may contain problem foods (for me). I believe these DAO caps keep me from suffering histamine headaches when I take them shortly before or with a meal of suspect foods.

If you look closely, most of these supplements with DAO all have pretty much the same ingredients. The biggest difference is price. I have also taken the Seeking Health brand and both seem quite equal to me at stopping reactions. At the time of purchase, the price was the only significant difference.

Will buy again! Super fast seller.Helps with histamine deregulation phenomenon.

I did not notice a difference.

This product works great when my histamine levels are too high and I need to bring them down and alleve an allergic reaction

This DAO works pretty good. The price is decent and the shipping was fast.

Have not tried but this should not be labeled vegetarian - the DAO comes from pig kidneys

Kind of pricey, but it really helps my histimine intolerance... I can drink coffee again!
