Organic Shiitake Mushroom Powder for Dogs

Shiitake mushrooms, also known as the "Elixir of Life", are treasured in traditional medicine for thousands of years in China and Japan. Our organic Shiitake Powder, sourced with care, is a nutrient-rich powerhouse. With essential vitamins, minerals, and immune-supporting properties, it's a valuable addition to your dog’s dietary choices. 

Shiitake mushroom is believed to offer potential benefits such as:

✔️ Supporting the immune system¹

✔️ Aiding in weight management³

✔️ Promoting heart health

✔️ Enhancing digestion and gut health

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. 


Shiitake mushrooms are well-regarded for their potential health benefits.


With its rich profile of phytonutrients, this organic powder is a fantastic nutrition source of Vitamin B2, B5, and D, ensuring you receive a nutrient boost with every sprinkle². Additionally, it contains vital minerals like copper, manganese, magnesium, phosphorus, potassium, selenium, and zinc, promoting overall wellness.

What sets this shiitake powder apart is its unique amino acid composition. It's one of the few plant-based sources that contain all seven essential amino acids, including linoleic acid known for its weight loss and digestion benefits. Incorporating this powder into your diet can help support your overall health goals¹.


Shiitakes, brimming with soluble dietary fibre, including beta-glucan, have the remarkable ability to increase the feeling of fullness, thereby aiding in weight management.

Additionally, shiitake mushrooms boast phytonutrients that promote heart health and bolster immune function. Researchers have even observed that rats on a high-dose shiitake diet experienced a substantial reduction in body weight gain, surpassing the results of low or medium mushroom diets. Even when added to a high-fat diet, shiitake mushroom powder still facilitated weight loss³.


Shiitake mushrooms are low in sodium and free of saturated fats. And they contain linoleic acid. This is an omega-6 essential fatty acid needed to support heart health. Lentinan also supports the heart.  

Cholesterol is also a risk for your dog’s heart, especially since many dogs eat a diet high in fat. Luckily, Shiitake mushrooms contain many compounds that fight cholesterol. They contain eritadenine, which inhibits an enzyme that produces cholesterol. The beta-glucans in shiitake also lower cholesterol². 

Finally, the potassium in Shiitake mushrooms may help reduce blood pressure. This is important for dogs with kidney disease or Cushing’s that may have high blood pressure⁴. 


Shiitake mushrooms promote digestion and gut health with their fibre content, which aids in reducing gut inflammation and maintaining a robust microbiome⁵. These mushrooms also offer a substantial array of around 30 different enzymes, including amylase, which plays a role in breaking down starches—a valuable attribute for dogs consuming high-starch kibble diets.


Shiitake mushroom (Lentinula edodes) is considered a valuable medicinal mushroom in many traditional forms of medicine and has been used in China and Japan for nearly 6,000 years. In Japan, the shiitake mushroom was often used as a medicine for treating bronchial conditions. They were also seen as an excellent substance to tonify the ‘Qi’ or vital life force.

The organic Shiitake powder is sourced from the finest ingredients and produced with utmost care. The mushrooms are grown in their natural habitat on wood in China, allowing them to develop their full potential in taste and nutritional value.

Dosage for Dogs

We recommend starting with a dosage of 0.7125 grams (approx. 8th of a teaspoon) per 15 kg of weight for the first 3 days.

We would then look to raise the dosage for serious need to 1 g (1/2 of a teaspoon) for every 15 kg of bodyweight per day, or as recommended by your Vet.
