HistaHarmony | Delayed Release DAO Diamine Oxidase Histamine Support Enzyme | 30,000 HDU | 60 Servings

It has taken me years to figure out that I have a histamine intolerance and these are the only enzymes that really help me. I love that they are so small and I usually only need to take 2 a day with an extra before a high histamine meal. A lot of other supplements require 6 capsules daily. Highly recommend!

This DAO enzyme works quite well to prevent histamine reactions from food. However, for me personally another brand (which I won't mention here) works even better. I suppose it depends on your level of histamine intolerance and how many HDU's (units) you require for a single dose. For many people, this supplement may be more than adequate. In my experience you don't want to take more DAO than is necessary because it can make you a bit lethargic (similar to the feeling of Benedryl). So, more or more powerful is not always better. I really like the packaging and individual sealed blister packs to prevent exposure to oxygen and the like. If you have problems with histamine intolerance (or think you do), give this one a try. If this supplement does nothing at all, then you probably don't have a lack of DAO enzyme. It's worth the money.

It works!!!this is the best dao supplement out there, good quality

Do not want to slam this product so I gave it a four star rating because the bloating it caused me was linked to my sulfite/sulfur issues. Although DAO does not contain sulfur, it must contain sulfur-containing amino acids like cysteine or methionine because it comes for pigs, which causes me major issues. So instead of helping my HIT it just complicates the issue and all the dovetail issues tied to it. To come to this conclusion regarding the amino acids I just googled "does DAO contain sulfur." Once I stopped taking it, the bloat seems to have gone away. Only sad thing is I had just bought a new box, sitting unopened, now in the supplement bone-yard!

Made my symptoms worse and didn’t help. Taking just beef kidney capsules seems to work better for me.Many people seem to like this, so I think it’d worth a try. The company reached out to me to offer a refund. That says a lot about how they back their product and I appreciate it.

Pop one or two of these when you are drinking red wine and youll be fine

I love the fact that this product is delayed release so that it can get to the intestines where it needs to be to work.

Amazing
