"My Naturopath recommended this brand specifically and I agree - it's great. I take one after each meal even if I didn't eat a food which might be a trigger. I take it that often partly because my Osteopath feels that a big part of my chronic pain and connective tissue disorder is related to Mast Cell Activation. This is the brand to buy because others have other ingredients and I only was the DAO and nothing else."

"I've tried liver capsules, but unless you actually eat Liver on weekly basis, you won't get enough DAO. As body ages, DAO enzyme production declines. Caffeine-containing drinks, coffee, and especially black tea, inhibit DAO. My stupid combo was aged cheese on a cracker, with two cups of English breakfast [palmface]. Lesson learnt. Enter Omne Diem DAO, which from here henceforth, I carry with me at all times.
If you know you'll drink beer/wine, enjoy a charcuterie board, have a tomato bisque - do yourself a favor - drink this 20-30 minutes prior. You can thank me later."

"It seems like my immune system reacts to high histamine levels in foods, and i’ve had to cut out so many things i love, including alcohol. This isn’t a cure-all, but if i know i’ll be having a couple drinks, i take 2 of these per drink, along with a DHM supplement, and it cuts back on histamine intolerance symptoms."
