Great product

Seems like a quality product. It’s just not something that worked for me.

I was feeling slight itching all over. Claritin did not seem to help. I thought that it might be from high histamine in foods and that I needed more DAO enzyme. This seems to start in summer when my tomato harvest is coming in and I am eating one everyday. However, once histamine levels get high than other histamine foods even with low levels can keep this perpetuating. I also added Zyrtec and found that worked better for me than Claritin. So I will keep this supplement as an option when I see that I may be needing it.

These have saved my life. Helps so much with digestive issues and eating out

Need double the dose to have any effect

Pills have large pieces of a black substance inside of them. This is not what they look like when ordered directly from Dr Amy Myers website. Obviously these are contaminated with something.

Better to provide third party test on actual inside gut Dao activity.

Item was left in heat outside and was contaminated and was not eligible for return
