HEART & SOIL Histamine and Immune Support – 3000mg DAO Enzyme Supplements with Bovine Thymus, Selenium & Vitamin A – Non-GMO, Allergen-Free – 180 Capsules

Love this stuff and use it often!

Noticeably better since using this supplement knowing it’s clean and coming from a legit source.

I use this particular product to help with mast cell activation. Kidneys have lots of chemicals in them that help block mast cells. And while I love eating nose to tail as much as possible (I am keto rather than carnivore, though time to time I do eat carnivore) and I eat organs, the most important organs are either not available to purchase or they require a huge preparation (like the kidneys) and the taste may just be marginal.So I have taken other brands before this one, which only have kidney supplements, which are fine, but I seem to thrive on this mix way better! I literally feel fantastic, all my mast cell issues are gone, have lots of energy, and look my best ever.I am definitely buying this product--I already bought it more than once and hope in time to be a subscriber for it, once it becomes available for such. I strongly recommend this over all others.Update: I sure hope this product becomes more readily available. I would like to see a subscription option started on amazon for it. I am a Heart and Soil gal deep in my heart.

The product has been amazing and in two weeks has already started to correct my Alopecia Barbae which nothing else I've tried medically has done! This gives an instant long lasting energy boost and has helped me feel amazing since I've added it to my nose to tail regimen! Amazing product and company!

I feel so much better. I have histamine intolerance and was recommended this in a Facebook support group. I was already taking other supplements and vitamins but when I added this I noticed a major difference.P.S. my family even noticed a major change in my energy and what I was able to get done throughout the day.

I should have done more research before purchasing this product but it’s non refundable. I took this one time and almost had an asthma attack. I had brain fog and a migraine that lasted 72 hours. This product induced histamine to release and cost $50+ I am hoping that the company will make it right but since I bought it off of Amazon there’s no return policy. This was not the answer to MCAS or allergy induce asthma & migraines.

For years my husband has struggled with a wheat allergy. This allergy has been unconfirmed by doctors, but confirmed by all our trial and error. Since taking this (has not even been one month), he has had no symtpoms at all! He has been eating bread and all kinds of other things that he used to avoid. It is truly a life saver!

I want to love this product so much but so far it’s been a bust for me. I took the full dose for five days and noticed significant GI disturbances so I reduced it to 4 pills a day for another five days and still issues. Have stopped the supplement feeling discouraged.
