From goat milk to soft chews to mushroom powder, we use USDA Organic mushrooms in tasty, easy forms. While many products focus on a single ingredient, we deliver complete protection to strengthen immune defenses and support overall vitality.

Maximum Beta-Glucans. Maximum Benefits.

I have a senior kitty that had a carcinoma removed from his ear. Some of the cancer had already infiltrated surrounding tissue, so even though the surgery went well, he was having some delayed and abnormal healing. The vet wasn't pleased with results, but i read somewhere that wild mushrooms can have a synergistic effect with antibiotics. I started adding 1 scoop per day to his food, and he suddenly started healing better. His ear will never be "normal" and the cancer may come back. But at the very least, his incision is starting to close, it is no longer oozing, and we can finally remove his cone.

I have 4 dogs and I use this for all my dogs as it has great health benefits. My dogs love it! They actually chewed through a container because they were trying to eat the powder. They love the taste and mushrooms have great benefits! I highly recommend!

Used a few containers of this product for my girl dog's lipoma/soft tissue sarcoma. Her lump got bigger and bigger. Now it's the size of a tennis ball. So for my dog, the product did nothing to help her lump. Perhaps it helped prevent future lumps or other issues, but hard to say. I was really hoping that this product would've shrunk her lump, but it didn't. Perhaps you will have better success with your dog and the product.

Just started using it for our Lab a week and a half ago. So far can't say much except if we mix the powder in her food, she eats it. Her energy does seem to have slightly increased. Only reason only giving 4 stars as we just started using.

To be honest, my order just arrived today.So I have not tried this.And i'm a little skeptical to while the bottle looks like everything is there.There is absolutely no seal.There is no plastic wrap.There is no seal under the lid which makes this a very easy product for someone to tamper with had i known the product was not sealed.I probably would not have ordered
