mushroom powder for dogs

HighV Mushroom Powder for Dogs is a daily meal topper made from nine functional mushroom extracts: Lion's Mane, Reishi, Cordyceps, Chaga, Shiitake, Maitake, Enoki, Tremella and Phellinus. Every extract is standardised to 30% polysaccharides, the beta-glucan-rich compounds mushrooms are valued for, so each scoop delivers a consistent, measurable amount rather than a vague "mushroom blend". Unflavoured, it stirs straight into wet or dry food. 90g tub, suitable for dogs from 6 months. Contains no CBD, hemp or THC.

Why functional mushrooms for dogs?

Functional mushrooms are the species people have used in traditional wellness practices for centuries, as distinct from the button mushrooms in the kitchen or the wild ones a dog should never eat on a walk. What makes them interesting for dogs is a group of compounds called polysaccharides, and in particular beta-glucans. These are complex fibres found in the mushroom cell wall that the immune system recognises and responds to, which is why mushroom extracts are so widely used for everyday immune support in both people and animals.

Different species bring different things to the table. Some are traditionally used for calm and resilience, some for energy and stamina, some for the skin and coat, and some for keeping older minds sharp. A blend lets you cover all of that in one scoop instead of buying four separate tubs.

What "standardised to 30% polysaccharides" means

Most mushroom products for dogs don't tell you how strong they are. A tub of ground-up mushroom might contain anywhere from 2% to 40% of the compounds you're paying for, depending on the species, the part of the mushroom used and how it was processed. Standardisation fixes that: each of the nine extracts in HighV Mushroom Powder is tested and adjusted so that 30% of it by weight is polysaccharides. It's the difference between knowing what's in the scoop and hoping.

Because the extracts are concentrated, a small amount goes a long way. A 10kg dog needs one level scoop a day.

The nine mushrooms and what each is known for

Lion's Mane

The shaggy white mushroom most associated with brain and nerve health. Owners often choose it for older dogs, or for breeds that tend to slow down mentally with age, because of its traditional link to cognitive sharpness and focus.

Reishi

Long used in East Asian traditions as an adaptogen, meaning a natural ingredient thought to help the body cope with everyday stress. It's a popular choice for dogs that are easily unsettled, and for general immune wellbeing.

Cordyceps

Traditionally valued for energy, stamina and efficient oxygen use. Suits working dogs, sporting dogs and seniors who could do with a bit more get-up-and-go.

Chaga

Grows on birch trees in cold climates and is one of the most antioxidant-dense mushrooms known. Traditionally used to support the immune system and help the body handle everyday oxidative stress; many owners also link it to a glossier coat.

Shiitake

A well-studied culinary and functional mushroom, naturally rich in beta-glucans and the polysaccharide lentinan. Traditionally used for immune support and a healthy heart and circulation.

Maitake

Known for its immune-supporting polysaccharides and traditionally associated with a healthy metabolism, which makes it a useful inclusion for dogs whose weight needs watching.

Enoki

The long, thin white mushroom you'll recognise from noodle dishes. It contributes B vitamins, selenium, potassium, dietary fibre and its own beta-glucans, supporting digestion alongside general wellbeing.

Tremella

Sometimes called the "beauty mushroom". Its polysaccharides hold water in much the same way hyaluronic acid does, so it's traditionally linked to skin hydration, coat condition and joint comfort.

Phellinus

Less famous in the West but highly regarded in East Asian traditions for its antioxidant and immune-supporting properties. It rounds out the blend for dogs that benefit from broader immune and gut support.

Which dogs benefit most?

• Senior dogs, for cognitive sharpness, energy and everyday immune support
• Active, working or sporting dogs that burn through a lot of energy
• Dogs that pick up every bug going, or seem slow to bounce back
• Dogs with a dull, dry coat or itchy skin with no obvious cause
• Dogs that find change, noise or being left stressful
• Owners who want a broad daily wellbeing supplement without adding treats or calories

If your dog has a diagnosed condition, is on medication that affects the immune system, or is under veterinary care, talk to your vet before starting. Mushroom powder supports a healthy dog; it doesn't replace veterinary treatment.

What to expect, and when

Mushroom extracts are a slow, steady supplement rather than a quick fix. Most owners describe the change as their dog seeming "more themselves" over a few weeks rather than a sudden difference.

• Weeks 1 to 2: your dog gets used to the powder in their food. Nothing dramatic should happen; a small number of dogs have slightly softer stools while the extra fibre settles in.
• Weeks 3 to 6: owners commonly report steadier energy, a brighter coat and, in older dogs, a little more alertness.
• Two months and beyond: the everyday immune and vitality support these extracts are known for builds with daily use. Keep it up rather than stopping and starting.

Feeding guide

Stir into your dog's usual wet or dry food once a day. With dry kibble, a splash of warm water helps the powder cling to the food. Do not exceed the recommended daily amount. Always provide fresh drinking water.

Suitability and safety

HighV Mushroom Powder is suitable for all breeds and sizes from 6 months of age. It contains no CBD, hemp or THC and can be fed alongside other supplements, including HighV soft chews and CBD pet products. If your dog is pregnant, nursing, has a diagnosed medical condition, or is on prescription medication, especially anything affecting the immune system, check with your vet before adding any supplement. Keep out of reach of children. Store in a cool, dry place with the lid firmly closed, away from direct sunlight. Always check the "Best Before End" date on the label. For animal use only.

Because it goes into food rather than being fed as a treat, Mushroom Powder pairs naturally with any of the HighV soft chews. Owners most often combine it with Immunity Dog Treats for a double layer of everyday immune support, Probiotic Dog Treats for the gut, or 8-in-1 Dog Treats for vitamins and minerals.
