How these figures are counted

Figures describe this selected library, including different placenta sources and study designs. Participant counts are summed across canine and feline publications, not verified unique animals. Laboratory mice and cultured cells are excluded from the dog and cat total. Duplicate copies of the same paper count once.

Vitality Enhancement

More interest in daily life and meals

You know their usual enthusiasm. A quieter greeting or less interest in meals can make you wonder what has changed.

  1. 2026

    Canine observations

    More vitality and interest in meals

    Uncontrolled exploratory study in senior dogs; owner-rated outcomes, not established efficacy.

    Owners reported improved vitality and appetite scores over 28 days in senior dogs receiving equine placental extract. These everyday ratings are the focus of this reading.

  2. 2023

    Case reports

    Less exhaustion during an older dog’s care

    One clinical case with concurrent treatment; it does not establish an energy benefit in healthy pets.

    An older dog with suspected anaemia showed reduced exhaustion after equine placental extract was added to prescribed treatment. Here, the observation is about energy during illness.

  3. 2026

    Case reports

    Renewed interest in meals during liver care

    One older cat receiving combined care; the extract’s individual contribution to appetite is unknown.

    A cat’s appetite returned during care for liver disease that included equine placental extract, medicines and nutritional support. This reading focuses on the reported change at mealtimes.

Changes in appetite, movement, skin or night-time behaviour are useful to discuss with your veterinarian, especially when new or persistent.

From the ingredient to your routine

One ingredient to explore.
A format that fits.

Our Japanese-made placenta products use equine placental extract. Choose your format by your pet’s species, size and labelled serving directions.

Research findings depend on the preparation, species and study design. Cow placenta research is labelled separately and does not establish benefits for our equine placenta products.

Browse all source summaries, including additional clinical observations.

Vitality, appetite and ageing-related assessments in senior dogs

2026 · Canine observations

A 28-day exploratory study reported improved owner-rated vitality and appetite, alongside lower composite ageing-assessment scores, in senior dogs receiving equine placental extract.

Uncontrolled exploratory study in senior dogs; owner-rated outcomes, not established efficacy.

Night barking in senior dogs

2022 · Case reports

Owners reported reduced night barking after equine placental extract was added to the care of three senior dogs.

Three dogs with cognitive dysfunction; uncontrolled cases, with other medicines used in some dogs.

Mobility observations in older dogs

2022 · Conference abstract

Veterinarians reported improved pain and activity scores over four weeks in dogs receiving a placental extract supplement.

Conference abstract; no control group, randomisation or blinding described.

Skin & coat observations in dogs

2023 · Canine observations

Researchers reported hair regrowth, improved coat shine and reduced hair fall during monthly assessments of dogs receiving equine placental extract.

Dogs with hair loss; no separate comparator group identified in the methods.

Corneal recovery: two clinical cases

2024 · Case reports

Two dogs received oral equine placental extract alongside ongoing eye-drop treatment, with subsequent clinical improvement.

Two clinical cases receiving eye drops; the supplement’s contribution cannot be isolated.

Coat condition & combined nutrition

2025 · Case reports

Coat coverage improved during a regimen combining equine placental extract, taurine and B vitamins.

One dog receiving several supplements and skin care; placenta’s individual effect is unknown.

Exploring cellular pathways in ageing

2021 · Preclinical research

Researchers reported increases in neural stem cell measures and dendrite length in cell experiments, and improved object-recognition memory in a mouse model.

Laboratory cells and a mouse model; not a clinical trial in pet dogs or cats.

Antioxidant pathways in skin cells

2023 · Preclinical research

Equine placental extract activated antioxidant signalling and lowered selected inflammatory markers in cultured skin cells exposed to UVB.

Extract applied directly to cultured human skin cells; not an oral pet supplementation trial.

Skin-cell ageing under oxidative stress

2022 · Preclinical research

Equine placental extract reduced the proportion of cells showing a senescence marker in cultured human skin fibroblasts exposed repeatedly to hydrogen peroxide or UVA.

Cultured human cells, not a trial in dogs or cats. The findings do not establish slower ageing or protection from sun damage in pets.

Cognitive observations in six older dogs

2026 · Case reports

Five of six older dogs had lower cognitive-dysfunction questionnaire scores at day 49, following four weeks of oral equine placental extract supplementation.

Six dogs; owner-reported scores and no comparison group. Lower scores indicate fewer reported cognitive signs.

Cow placenta extract and cognition in older dogs

2026 · Canine controlled trial

Dogs receiving cow placenta extract had lower cognitive-behaviour questionnaire scores than the placebo group after six months.

Cow placenta, not equine placenta. A different preparation from the ingredient in our collection.

Digestive stability during veterinary care

2022 · Case reports

A dog with protein-losing enteropathy had no reported recurrence of abdominal fluid accumulation or diarrhoea during a combined regimen that included equine placental extract.

One clinical case with prescribed medicines and other supplementation; not a study of routine digestive support.

Energy and condition during anaemia care

2023 · Case reports

The report describes reduced exhaustion and maintained physical condition after equine placental extract was added to an older dog’s ongoing care for suspected immune-mediated haemolytic anaemia.

One dog with suspected disease receiving prescribed treatment; not a trial of energy support in healthy pets.

Eye comfort during care of an older cat

2025 · Case reports

An older cat showed improvements in eye discomfort and several corneal signs after equine placental extract was added alongside ophthalmic treatment.

One cat receiving multiple treatments. The title uses “cats”, but this report concerns a single patient.

Appetite and stability during feline liver care

2026 · Case reports

An older cat’s appetite returned and liver blood markers improved during combined care that included oral equine placental extract.

One cat receiving medicines and nutritional support; not evidence of a general appetite benefit in healthy cats.

Kidney-injury pathways in a mouse model

2025 · Preclinical research

In mice with adenine-induced kidney injury, oral equine placental extract was associated with lower indoxyl sulfate levels and reduced measures of kidney tissue injury, fibrosis and inflammatory-cell accumulation.

A 14-day laboratory mouse study, not a clinical trial in dogs or cats. It does not establish a treatment or preventive benefit for pets with kidney disease.

A selected collection from the supplied placenta research, including studies with Furrmacy involvement. Each summary identifies the study design, preparation and research relationships. This collection is not a systematic review.
