Designs for Health HistaGest-DAO - Diamine Oxidase DAO Enzyme to Support Digestion of Histamine-Containing Foods - 20,000 HDU DAO Diamine Oxidase Enzymes (60 Gastro-Resistant Tablets)

Works well for Mast cell issues

Great product. Really works!

I need this as I do not make enough DAO to process histamine. These allow me to eat many more foods without anaphylaxis

I honestly don't know if this even really does anything. I couldn't eat whatever histamine foods I wanted while taking it, got tired of paying 70 bucks every few weeks, and now eat exactly what I was eating when I took it without issue. (Still have to be low-histamine, just not as broke).

These tiny pills seem to make a difference in my skin and digestive system after I eat particularly high histamine foods. I have been taking two before meals.The only thing I was not happy with was the package was taped closed with a type of perforated tape and that was the only thing that sealed the product. Once I opened the outer box (that had the not very secure tape), the actual dispenser didn't have anything protecting it from being used. It needs to be better protected so that you know it hasn't been tampered with before it gets to you.

Saved my life and quick delivery

The media could not be loaded. The packaging is so unique - I had to make the attached video so you can see this.The product really works too - as well as my regular DAO and possibly a little better. What’s really interesting is this contains 20,000 HDU which is the same amount my regular sized histamine supplement contains.When I was viewing this online, I wasn’t super happy about all the extra ingredients. But since I know it’s a good brand I wanted to try it anyways. However, when I saw it size and that it’s a pill versus a capsule, I suddenly didn’t mind the extra ingredients, because I realized they are in super small doses.On a day-to-day basis, I don’t care about the size of the DAO supplement. However, when/if I travel or go camping, this size is definitely more convenient.I can also see this is being really good for kids and people who have a hard time swallowing pills. I can easily swallow one, without any water.

My food allergies got even worse. I am allergic to something in those pills.Also, it was impossible to remove the pills from the container. After much probing, a bunch of them came out. It was then impossible to put them back.
