Not every gut supplement needs a long ingredient list — sometimes the whole product is one thing, dug out of the ground, and the argument for it rests entirely on what that one thing does once it's mixed into a meal.

AniForte's Moor Mud is sourced from a moor spa in Bavaria, Germany, and is pure natural moor mud with no other stated ingredients. It's intended to support a dog's or cat's stomach, immune and intestinal function by binding to and flushing out harmful substances, and AniForte say its humic acid content can stimulate appetite and help regulate stool consistency. It's mixed into daily feed and comes in a 750g tub.

On the daily amount. AniForte don't give a specific daily quantity or a dosing scale by animal weight on the facts we hold, so check the tub itself for their measuring guidance rather than adding it by eye.

Who it's for: owners of a dog or cat with unsettled digestion who want a single-ingredient supplement to mix into food, rather than a multi-ingredient blend.
