Here’s Why Our Customers Love Us

Don't Take Our Word For It

After a very successful 10-day trial of the Histamine Digest with Umbrellux DAO I just ordered another 120 capsules. I am very encouraged that this could be a long-term solution for my histamine intolerance without resorting to the extremes of a low histamine diet. 
Alec
This stuff saved me. I have only been taking it for a couple days now and have seen a huge improvement in my histamine intolerance symptoms – mainly hives and abdominal pain.
Jordan
I ordered Histamine Digest by recommendation from my nutritionist, so whenever I have a ‘flare up’ I have taken this supplement and found a lot of relief, especially related to bloating in the face and abdomen.
