About Saw Palmetto
Saw palmetto is a dried berry extract from a native palm, included in some pet supplements as a hormone-related support herb rather than a nutrient.
Saw palmetto is a botanical supplement sometimes added to pet health products to support urinary tract and prostate health rather than as a nutritional ingredient, and is most commonly used in male dogs for its potential anti‑androgenic and anti‑inflammatory effects. Evidence in pets—especially cats—is limited, dosing is uncertain, and it can interact with hormone therapies or blood‑thinning medications and cause gastrointestinal upset, so it should be used only under veterinary guidance.
- Derived from
- berry of the Serenoa repens palm
- Primary role
- botanical supplement for urinary and prostate support
Why it's used
Extracts of the berry are rich in fatty acids and plant sterols that have been studied in humans for lower urinary tract symptoms linked to an enlarged prostate. Some pet supplement makers carry that same rationale over to intact male dogs, marketing it alongside other adaptogenic or glandular-support herbs.
Common concerns
- Lack of proven effect in dogs A controlled study of dogs with prostatic hyperplasia published in the American Journal of Veterinary Research found that a Serenoa repens extract given for 91 days changed neither prostate weight, prostate volume, histologic scores, nor serum testosterone compared with untreated dogs.
- Limited data in cats Most available research on saw palmetto comes from human and dog contexts, with very little published evidence specific to cats.
- Possible interactions Because of its reported hormonal and anti-inflammatory activity, saw palmetto is discussed as a possible interaction risk alongside hormone therapies or anticoagulant medications, which is why guidance generally points toward veterinary input before combining it with other treatments.
- Digestive upset Gastrointestinal upset has been reported anecdotally as a side effect of saw palmetto supplementation.
Also relevant
The same 91-day study reported no adverse changes in bloodwork, urinalysis, or body weight in the treated dogs, suggesting the extract was tolerated even though it did not shrink the prostate.
