This powder is built for the long game. Real change takes time and builds with every scoop. The more consistent you are, the harder the ingredients work. Stick with it, and you’ll see it in them.†
Research Backed Ingredients
Two ingredients. Zero fillers. Every scoop delivers a clinically studied mushroom and a live probiotic — dosed at levels that actually matter.
Organic Turkey Tail Mushroom
Turkey Tail is one of the most studied mushrooms in the world, used in Japan for over 30 years and a staple of traditional wellness practices for centuries. It's naturally rich in beta-glucans and polysaccharides — compounds researched for how they support a normal, balanced immune response and healthy cellular function. Every scoop delivers a full 1,000 mg of organic fruiting body.

Lactobacillus Acidophilus
Here's the part most brands skip: dogs can't produce chitinase, the enzyme needed to break down mushroom cell walls. That's why we pair every scoop with 1 billion CFU of Lactobacillus acidophilus — a widely used probiotic strain that supports the breakdown and absorption of the beta-glucans, while supporting gut balance, comfortable digestion and nutrient absorption.
Take Action TodayOne scoop. That is the whole routine.
No pills to hide, no wrestling, no skipped days. If your dog eats breakfast, your dog takes KOIRRA.
Scoop
The scoop is in the jar. Under 25 lbs gets 1 scoop, 25 to 50 lbs gets 2, over 50 lbs gets 3.
Stir into breakfast
The bacon-flavored powder disappears into his regular food. Most dogs lick the bowl clean before touching the rest.
Repeat every morning
Daily consistency is the whole game. Gut support first, then normal immune support builds week after week.†
Takes about 10 seconds a day. Refills arrive automatically so the routine never breaks.

Not folklore. One of the most studied mushrooms on earth.
We did not pick turkey tail because it sounds nice. We picked it because the research base is decades deep, and then we solved the absorption problem most brands ignore.
45+ years
Of formal research
Turkey tail extracts have been formally studied and used in Japan since the late 1970s. Its beta-glucans and polysaccharides are among the most researched natural compounds for supporting a normal, balanced immune response.†
The chitinase gap
Why raw mushroom is not enough
Dogs cannot produce chitinase, the enzyme needed to break down mushroom cell walls. Without help, much of a plain turkey tail powder simply passes through. Every KOIRRA scoop pairs 1,000 mg of organic fruiting body with 1 billion CFU of L. acidophilus to support breakdown and absorption of the beta-glucans.†
~70%
Of the immune system lives in the gut
That is why gut balance and immune support belong in one formula. The probiotic supports comfortable digestion and nutrient absorption while the beta-glucans support his normal immune response, every single day.†
Every batch is 3rd-party lab tested for purity and potency. Organic fruiting body only, never grain-grown mycelium filler.

What dog parents are saying
Real comments from our community of 14,932+ dog parents.
Karen T.
My 11 year old lab has a fatty lump the vet said to just watch. Watching felt awful. At least now I'm doing something for him every morning and honestly he runs to his bowl for it. Month 3 for us.
KOIRRA
This is exactly why we made it, Karen. Give him a scratch behind the ears from us. And remember, any new or changing lumps should always be checked by your vet.
Diane R.
Skeptical dog mom here, I've wasted money on supplements before. Ordered 1 jar to test. My picky corgi ate it day one, no drama. His stomach has been way more settled since week 2 or 3. Just ordered the 5 jar bundle.
Mark V.
The probiotic pairing is what sold me. I looked it up and it's true, dogs can't break down mushroom cell walls on their own. Most brands don't even mention it. Respect for actually explaining the mechanism.
Sandra P.
9 year old golden. Around week 5 my husband asked what got into her because she brought the ball back twice on our evening walk. Little things, but they matter when they're getting older.
Jill A.
Asked about the guarantee before ordering and they answered within a day. 90 days, no forms. That's what got me to try it, and 6 weeks in we're staying.
Individual experiences, self-reported by customers. Results vary. KOIRRA supports normal immune response, gut balance and everyday energy; it does not treat, cure or prevent any disease.†
WHY KOIRRA EXISTS
It started with the words "we will just keep an eye on it."
If you have ever heard those words at the vet, you know the feeling. You drive home, your dog asleep on the back seat, and you think: so my job is to just... watch?
That was us. A senior dog slowing down, a lump we were told to monitor, and absolutely nothing we could DO between check-ups. We started reading. Turkey tail kept coming up: decades of research, used in Japan since the 1970s, one of the most studied mushrooms in the world.
Then we found the catch nobody talks about. Dogs cannot produce chitinase, the enzyme that breaks down mushroom cell walls. Most turkey tail powders largely pass straight through. So we built the version we wished existed: 1,000 mg of organic fruiting body paired with 1 billion CFU of a live probiotic to support absorption, in a bacon-flavored powder a dog actually begs for.†
KOIRRA is not a miracle and we will never pretend it is. It is the thing you can do every single morning, backed by a 90-day guarantee because judging a daily routine takes time.
