Organic Reishi Mushroom Powder for Dogs

Reishi mushrooms carry the illustrious title of the "Mushroom of Immortality". They have been a cornerstone of traditional Chinese medicine for pets, and their legacy extends across centuries with use by healers and shamans worldwide. Sourced from carefully cultivated reishi mushrooms, this powder offers the perfect balance of tradition and modernity.

These mushrooms are recognized for their potential to help with: 

✔️ Support natural defences against stress¹ 

✔️ Improve sleep quality²

✔️ Bolster the immune system³ 

This product has been tested for pesticides, artificial fertilisers, heavy metals, e.coli, yeast, mould, salmonella and foreign matter. It contains no bulking agents, added sugar, palm oil or GMO. 




During times of intense stress, persistent fatigue often sets in, mainly due to the continual drain on the central nervous system's energy reserves. Reishi mushroom powder is believed to support the body's natural defences against stress¹. Reishi mushrooms contain adaptogenic beta-D-glucans and triterpenes that might help soothe the nervous system and reduce mental stress. This calming effect is said to be akin to achieving a state of focused relaxation, much like meditation. Reishi's ability to calm the central nervous system can also assist with anxiety and restlessness⁴. 


Sufficient and restful sleep is crucial for the overall well-being of dogs, aiding in their growth, learning, cognitive development, and immune system function. Studies suggest that Reishi mushroom powder can improve sleep quality and lead to a lesser feeling of fatigue². 


Reishi mushroom powder is also thought to promote a healthy immune system³. It contains beta-glucan, which is believed to potentially benefit a dog's immune system by stimulating and enhancing immune responses, promoting cytokine production, and supporting the body's natural defences⁵. 


Reishi mushrooms are grown in dark, damp forests and rotting logs, making them a rare find in the wild. However, recent advancements in cultivation techniques have made it possible to grow these medicinal mushrooms in China, Japan and the United States. This not only ensures a sustainable supply but also preserves the wild stands of reishi. Our reishi powder is grown on Duan wood in China as nature intended, by experts with decades of knowledge and experience, for maximum nutritional benefits in our powders.

Dosage for Dogs

We recommend starting with a dosage of 0.356 g (16th of a teaspsoon) per 15 kg of weight for the first 3 days.

We would then look to raise the dosage to 1.42 g (1/4 of a teaspooon) for every 15 kg of bodyweight daily or as recommended by your Vet.

If there is a greater need, this dosage can be raised to as much as 2-3 times this amount.
