DAO Enzyme
Bloating after meals. Headaches after wine. Flushing after leftovers. Sound familiar?
DAO Enzyme supports healthy histamine breakdown so you can enjoy the foods you love with comfort and confidence.
How to Use It:
- With meals: Take 1 capsule before eating or drinking anything high in histamine such as aged cheeses, wine, fermented foods, cured meats, leftovers, citrus, or overly ripe fruit. This is the most common use and where most people notice the most support.
- On an empty stomach: This is the one most people miss and is actually quite a genius trick. Your gut bacteria and your gut's immune system also produce histamine. If you have dysbiosis, SIBO, or an overactive gut immune response, try taking 1 capsule on an empty stomach. If you feel better within 30 minutes, that tells you your microbiome or gut immune system is producing excess histamine. Continue using it this way as needed.
- For children: Ages 4 and up. Open the capsule and sprinkle on a bite of applesauce if they can't swallow it.
- During pregnancy: With your healthcare professional's approval. Your placenta produces massive amounts of DAO but not until the 2nd trimester, which is exactly when most morning sickness eases. Supporting healthy histamine levels during the 1st trimester may support comfort.
- While breastfeeding: Histamine from your gut absorbs into breast milk. Infant colic is associated with higher histamine levels in breast milk. Supporting your own histamine balance may support comfortable feeding for your baby.
When to Reduce or Stop:
- DAO Enzyme is what I call a palliative supplement. It provides the enzyme your body needs right now, but it doesn't fix the underlying reason your DAO may be low. The goal is to heal your gut lining, rebalance your microbiome, and calm your immune system so your body's own DAO enzyme works well on its own.
- As you make progress in those areas, you'll naturally need less DAO Enzyme. Some people go from taking it at every meal to only when they eat out or travel. Others find they eventually only need it during high-histamine seasons or stressful periods. Let your body guide you.
- If your stools become harder to pass, that's a sign you may be taking too much. High histamine in the gut is associated with loose stools so when you lower it effectively, things can firm up more than expected. Simply reduce your dose to mealtimes only, or take a break. If things normalize, adjust accordingly.
Suggested Use:
- As needed, anytime, take 1 capsule before eating or drinking.
- Alternatively, as needed, take 1 capsule away from food or drink if wanting to support uterine comfort during the menstrual cycle, occasional nausea from pregnancy or healthy histamine levels in your digestive system.
- Capsules may be opened and sprinkled on a bite of food.
- Use as directed by your healthcare professional.

The new capsule form are so much easier to swallow!
I've been coming to the Apothecary for years for supplements that I read about and seek their advice on efficacy and best form of ingestion to get the True Value of some of the nutrients and minerals we may be lacking. The staff is always friendly and knowledgeable and explain the differences between Brands and formulations of supplements that, to an uninformed person, would look to be identical. I count on their advice and appreciate their expertise.
Trying It For the First Time It Work's Great So I Gave Some To My Neighbor And She Loves It So I Told Her Where She Can Buy It. I Ordered Another Bottle Of The Peppermint But You Don't Have It In Stock. LOVE IT.

I had a wonderful experience at Village Green Apothecary. Their staff is top notch in regards to both fund of knowledge and customer care. Gail, the owner, was extremely pleasant taking time to have a one on one conversation with me. Brian also showed himself to be extremely well read, passionate, and driven in this field. You won’t regret coming here for your health needs.

Organic Chamomile with Lavender
I've been using essential oil balms for aches and pains, and they definitely help but their smell is rather strong. Magsoothium cream, by contrast, has a mild, pleasant flowery smell. I use it when I go out and do find it effective for moderate pain. I also use it at bedtime on my calves, as the magnesium helps with leg cramps which often wake me up - and it might be helping me to sleep better as well! I first ordered the small size to test it out, but took advantage of a recent sale and ordered two of the large size.
I appreciate how Village Green supplies the order quickly and efficiently!
