Pairs well with:

This small but mighty jar contains finely blended powder from 10 of the highest quality mushrooms. Fera's organic mushrooms are derived from 100% fruiting bodies which contain the highest levels of Beta glucans - the active polysaccharides that support a healthy immune system.

What is β-Glucan? They’re the most important component found in mushrooms!
Research shows beta glucans effectively support a healthy immune response. But not all mushrooms contain enough beta glucan levels. At Fera, we test our mushrooms to measure beta glucan levels to guarantee effectiveness and quality.

You won't find any fillers, mycelium, grain or starch in our immune support blend. Only 100% goodness!

Fruiting Bodies > Mycelium

Never settle for less. At Fera, we always choose the best of the best. Each one of our 10 organic mushrooms is 100% fruiting body. The majority of mushroom supplements contain mycelium which are grown on grains, lowering the mushroom’s active compounds. The “real mushroom” which is the above ground fruiting body, offers a more potent and higher quality product than mycelium extracts.

Our mushrooms come from carefully selected cultivation areas deep in the mountains of China, far removed from industrial pollution, so the growing environment stays clean and pure.

Yes! Quality control is our top priority, so our mushrooms are tested at every stage of their journey. Before leaving China, the mushrooms are tested for microbial contaminants (including bacteria, yeast and mold, E. coli, and coliforms), heavy metals, and pesticides, followed by a final organoleptic evaluation of their appearance, aroma, and texture.
Once they arrive in the US, qualified third-party labs repeat the microbial, heavy metal, and pesticide testing to confirm they meet US standards. These labs also run additional tests to verify quality and authenticity.

All of our mushroom extracts are made using a hot water extraction (90-100 °C) which are then spray dried to create a powder.

Our blend typically ranges between 30-50% beta-glucans, and since this can vary slightly batch to batch due to natural variation in the mushrooms themselves, you can check the exact percentage for your specific jar using our COA lookup tool.

    Amazing

    My great Dane just turned nine he has DCM and intestinal disease. He’s been on fair pets mushroom powder for a few years as well as their cardiac supplement and vitamin powder. He saw his cardiologist over the summer for his annual visit. She said if she did not know he was a DCM dog and on heart medication she would never know he has a heart issue because that’s how good his heart looked on the ultrasound, She said the heart medication along with the supplements I give him are working. She looked amazed! I swear by Fera Pets products. 🩷

    Very convenient and doggo loves it

    Started using this because my sweet baby was killed by cancer and I never want to go through that again. I am giving this to my other one in hopes that she will not have to suffer the same fate.

    Helps boost immune system of my cats!

    I have 4 cats and the LOVE the taste of the mushroom and eat their food right up when I give it to them along with their Fera probiotics! I have 2 cats that need extra support with maintaining a healthy immune system. One cat has a stomach sensitivity and sneezes. Since he has been taking this, he hasn't sneezed as much and his stomach is not as sensitive!
