Liver & Kidney Clean

Liver/Kidney Clean is Four Leaf Rover's veterinarian-formulated liver and kidney support supplement for dogs — a carefully composed blend of organic milk thistle seed, four medicinal mushrooms (reishi, cordyceps, maitake, shiitake), broccoli sprouts, and supporting botanicals. It's designed to support your dog's natural detoxification pathways and maintain normal liver and kidney function, gently and steadily, through daily use or targeted reset cycles.

Modern dogs face a constant toxic load — glyphosate on grass, chemicals in tap water, heavy metals in food, flea and tick treatments, vaccinations, household cleaners, plastics. The liver and kidneys carry the bulk of the work processing and clearing those compounds, and over time that load can catch up with them. Liver/Kidney Clean works at the level of the organs themselves, supporting their natural filtration and detoxification capacity. Available in 37.2g.

Every day, a dog's body filters and processes far more than most people realise. The liver breaks down medications, metabolites, hormones, and environmental toxins. The kidneys filter waste products from the blood and maintain fluid balance. Together, they are the body's primary detoxification system — and both are constantly working.

In a dog with healthy organ function, this process is efficient and invisible. But modern dogs face an unprecedented toxic load. Glyphosate sprays on lawns, heavy metals in municipal water, pesticides in commercial food, flea and tick treatments, routine vaccinations, and the cumulative exposure of an urban environment all add up over time. The liver and kidneys can process a great deal, but when the load is continuous, their capacity can gradually diminish. Liver/Kidney Clean is designed for dogs living in that reality — supporting the organs with plant-based antioxidants, adaptogenic mushrooms, and traditional liver herbs, rather than letting them cope alone.

Organic Milk Thistle Seed. Milk thistle is the most studied liver-supportive herb in Western herbalism. It contains silymarin, a group of flavonolignans shown to support liver cell detoxification, protect hepatocytes from oxidative damage, and maintain a normal inflammatory response in liver tissue. While its primary action is on the liver, milk thistle also offers protective effects for the kidneys by reducing oxidative stress.

Organic Broccoli Sprout Powder. Concentrated source of sulforaphane, a compound that activates Phase II liver detoxification — the pathway the body uses to neutralise heavy metals, pesticides, and other environmental toxins so they can be safely eliminated. Also provides antioxidant and gut health benefits.

Organic Reishi Mushroom Extract. Highly regarded in both Traditional Chinese Medicine and modern functional medicine for its liver-supporting properties. Contains triterpenoids and polysaccharides that support liver regenerative capacity and overall organ health. Also acts as an antioxidant for kidney function.

Organic Cordyceps Mushroom Extract. Cordyceps is traditionally associated with kidney support and energy. Contains cordycepin and polysaccharides that support both liver detoxification processes and kidney function. One of the more targeted mushrooms for combined liver/kidney support.

Organic Maitake Mushroom Extract. Rich in beta-glucans and antioxidants. Supports immune response and helps maintain healthy metabolic balance — which benefits the liver by reducing its workload. Traditionally used for liver and overall metabolic health.

Organic Shiitake Mushroom Extract. High in ergothioneine, a powerful antioxidant that helps protect the liver and kidneys from oxidative stress. Also contains polysaccharides like lentinan, which support immune function alongside detoxification.

Organic Marshmallow Root. Mucilaginous herb that soothes and protects mucous membranes throughout the digestive and urinary tract. Its diuretic action also gently supports the kidneys in flushing toxins, promoting healthy kidney filtration.

Organic Dandelion Root. A classic liver-support herb in Western herbalism. Traditionally used to support liver function and as a natural diuretic to assist kidney function. Rich in antioxidants that contribute to a balanced inflammatory response.

Organic Burdock Root. Contains inulin, a soluble fibre that supports healthy gut bacteria — important because the gut, liver, and kidneys work together in detoxification. Also rich in antioxidants that neutralise free radicals.

Natural Curcumin. The active compound in turmeric. Supports a normal inflammatory response and helps the liver process toxins more efficiently. Carbon-14 tested to ensure authenticity — guaranteeing it is plant-derived and not synthetically produced.

Phase II liver detoxification. Broccoli sprouts and sulforaphane activate the Phase II pathway that processes heavy metals, glyphosate, and environmental toxins for elimination.

Liver regenerative capacity. Milk thistle and reishi support the liver's ability to regenerate healthy tissue and maintain normal enzyme function.

Kidney filtration and flow. Marshmallow root, dandelion, and cordyceps support kidney filtration capacity and gently promote healthy urine output — key to flushing waste products efficiently.

Antioxidant protection. Shiitake's ergothioneine, reishi's triterpenoids, and curcumin protect both organs from the oxidative stress produced during chronic toxin processing.

A balanced inflammatory response. Curcumin, milk thistle, and dandelion together support healthy inflammation levels in organ tissue.

Gut-organ axis. Marshmallow root and burdock support gut lining integrity, which directly affects how much of what reaches the bloodstream needs to be filtered by the liver and kidneys in the first place.

Liver/Kidney Clean is a foundational product for any dog living a modern urban life — particularly dogs exposed to lawn sprays or agricultural chemicals, dogs on municipal tap water, dogs eating commercial food (even high-quality options), and dogs who have received medications, vaccinations, or flea/tick preventives in the last 90 days. It is also valuable for senior dogs whose liver and kidney function may be naturally less efficient, and for dogs with a history of drug or chemical exposure.

For dogs with diagnosed liver or kidney conditions, Liver/Kidney Clean is not a treatment — it is a supportive addition that should be used under veterinary guidance alongside prescribed care.

Liver/Kidney Clean pairs beautifully with Protect for comprehensive detox and gut support, since Protect binds toxins at the gut level before they reach the liver. For dogs who need broader antioxidant and polyphenol support, Green Rover adds a whole-food layer of cellular detox support. For foundational gut lining repair that supports healthy detoxification, Gut Guard is a natural companion.

Every batch of Liver/Kidney Clean is third-party tested for heavy metals, pesticides, and microbial contaminants, with a Certificate of Analysis available on request. Four Leaf Rover holds the NASC Quality Seal and is certified Plastic Negative by rePurpose Global. Manufacturing is GMP-compliant.
