How are your mushrooms grown?

Four Leaf Rover’s mushrooms grow on wood. This ensures that the helpful compounds you look for in mushrooms are actually in them.

The greenhouses have fresh water and air filtering through, with natural sunshine coming in.

After harvest time, the mushrooms are tested for chemicals and contamination.

How do I know if I have a real mushroom product?

You'll know the mushrooms you are giving to your dog are high quality if they contain the whole fruiting body and not just mycelium like most mushroom products.

Mycelium is not the whole mushroom. It is grown on grains like oats and rice, then ground up into a powder.

The problem is, if you’re buying a mycelium mushroom product, you’re missing out on the rich beta-glucan content that comes from the whole fruiting body that you’re looking for for your dog.

Beta-glucans are active compounds found in mushrooms. And the whole fruiting body offers more vitamins and minerals for your dog.
