USDA Organic Mushroom Blend for Immune Support

96 Reviews

Scroll To Reviews

We routinely take supplements to stay healthy and prevent illnesses, and we believe that our pets should, too! That's why we created our Organic Mushrooms Blend since “an ounce of prevention is worth a pound of cure.” For starters, these organic mushrooms are designed to strengthen immune system function and response. On top of that, they support brain health, enhance cardiovascular function, promote healthy digestion and help normalize blood sugar levels. This powerful blend of mushroom magic will keep your dog or cat ready to take on any day for many years to come.

This small but mighty jar contains finely blended powder from 10 of the highest quality, immune-boosting 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 stimulate an increased immune response and may even fight cancer. 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.

Shiitake Happens

but it doesn't have to, with Fera's organic mushrooms

  • 10 Organic Mushrooms 🍄

    Sourced from the highest quality mushroom farms, our USDA organic certified mushrooms feature ZERO fillers, mycelium, grain, starch and only 100% goodness.

  • The importance of a healthy immune system.

    According to the AVMA, approximately 1 in 4 dogs will, at some stage in their life, develop neoplasia. Almost half of dogs over the age of 10 will develop cancer. Mushrooms, and their chemical compounds such as beta-glucans strengthen the immune system to fight cancer and may stop or slow the growth of tumors.

  • Mushrooms as a Superfood

    Mushrooms not only enhance the immune system, they also support the liver, brain, digestion and heart! ❤️

Mushrooms utilized for medicinal purposes are rarely from North America. Most mushrooms come from Asia, primarily China. In fact, China produces about 85% of the world’s mushrooms. We have selected cultivation areas in China that are deep in the mountains and far from industrial pollution. We stand by our Chinese partners 100% and source only the highest quality ingredients.

Yes! Quality control is our top priority. Before exporting the mushrooms from China, they undergo rigorous testing for microbials (bacteria, yeast and mold, E.coli, and coliforms), heavy metals, pesticides, and a final organoleptic evaluation. Once the mushrooms have arrived in the US, testing is repeated by qualified 3rd party labs for microbials, heavy metals, pesticides that exceed US standards, beta glucan testing to ensure presence of active compounds, ergosterol testing to ensure fungal purity, alpha glucan testing to guard against carriers, Reishi extracts analyzed for triterpenodids, cordyceps analyzed for cordycepin, and a final organoleptic evaluation.

All of our mushroom extracts are made using a hot water extraction (90-100 degrees). Some of our concentrated mushroom extracts are made using both hot water & alcohol (also known as "Dual Extract" or "DE"). After these go through the hot water extraction process, they also go through a 50-95% @80 degree ethanol extraction.

Our Mushroom Blend has anywhere between >30-50% Beta Glucans. It changes between batches due to variations in mushrooms.

    Our dogs loved the taste!

    We were thrilled to find a veterinarian formulated supplement for immune support with no inactive ingredients. We have just started adding this into our pets supplement rotation and are happy to report that even our fussy dog approves!

    Thank you Fera!

    We give Fera Organics Immune Support a 10/10!

    We loved finding a veterinarian formulated, organic supplement for our crew!

    We have four dogs (18 months, 4 years, 5 years and 6 years) and a cat (10 years) all of whom have different activity levels and needs. Finding a single supplement that benefits them all (AND that they all enjoy) is always a win in our house!

    Great Addition To Your Pet's Diet!

    I have seniors and brachy kitties, subsequently I wanted to add an immune supplement to their diet to keep them healthy as I am conscious about health. Mushrooms provide an amazing and natural booster as well as this product has unique ingredients that dont overlap with any other supplement i've seen on the market, subsequently it can be combined with other supplements too!

    It's a great powder and easily mixes into wet food.
