Carlyle Grass Fed Beef Kidney Supplement | 200 Capsules | 3000mg | Pasture Raised Desiccated Bovine Supplement | Hormone and Pesticide Free | Non-GMO, Gluten Free | by Herbage Farmstead

The Carlyle Grass Fed Beef Kidney Supplement is a great source of DAO. I take them for breaking down histamine and they work great! I am sensitive to the plant-based DAO made from pea sprouts. The porcine (pig) ones don’t agree with me like beef do. I have been taking them for 4 years and have tried ALL the beef ones from expensive to budget-friendly (like these) and these are my favorite. Being grass-fed and New Zealand sourced is important to me, as they are a healthier beef source. These are my favorite and I have them on subscribe and save. I take anywhere from one to three (10-15 minutes before eating) per meal, depending on how low or high the meal is in histamine. I never have a bad reaction. They are the best bang for your buck too, which is always a plus.

I love these kindney supplements. I've taken kidney supplements for a couple of years and a few months ago found this brand. It works just as well but it more economical. It has helped my stomach so much.

Love the quality and price.

WOW do these work fast for clearing histamine. Purchased two more bottles.

Works great as a DAO supplement for histamine-intolerance. Only drawback is the rice flour filler, if that’s an issue for you.
