Every bit helps
I have terrible allergies and have yet to fully suppress them, but this enzyme (paired with antihistamines and other supplements) has made this past allergy season bearable. It has now become a part of my year round routine even when I go off of the antihistamines.

Enzyme a very good Product
I've used this product for about a month now and while more experience will give me a better idea of how useful it is, having used it for this month I already sent a difference in how I feel in response to histamines. Ordering it from Solaray was as easy as could be.

Solaray DAO enzyme
Hi, my doctor suggested a form of DAO as I tested very high histamine. I suffer from celiac and fibromyalgia. So far I've taken this for a couple of months. I feel a little relief in my allergies but not significantly better yet. Maybe the 6 month marker will tell. It is pricey but worth it to feel better. I've taken exactly as directed. I hope this helps.

    What is akkermansia?

    Akkermansia muciniphila (A. muciniphila) is a naturally occurring bacteria found in the digestive tract. Akkermansia feeds on the mucus layer surrounding intestinal cells without destroying it, allowing the gut lining to grow back stronger over time.

    What are CFU?

    CFU—short for colony forming units—are units of measurement that express the potency of a probiotic.

    What is a microbiome?

    A microbiome is a community of microorganisms that live together in a particular habitat. For example, the gut microbiome is comprised of bacteria, viruses, and other organisms that contribute to nutrient absorption, digestion, and directly impact overall health.
