Saw palmetto is a popular herbal supplement that has been used for centuries to treat a variety of ailments. It’s gained popularity in recent years for its purported ability to reduce prostate enlargement and improve symptoms associated with frequent urination.

However, does saw palmetto have any side effects? Does it cause erectile dysfunction? Can it damage the kidneys or liver? Does it increase testosterone? Can you take too much? We answer all these questions and more in this blog!

Side Effects & Erectile Dysfunction

Despite being used for many centuries to treat various medical conditions, there are some potential side effects associated with taking saw palmetto. These include nausea, headache, dizziness, vomiting, and diarrhea.

In addition, saw palmetto can interact with certain medications such as anticoagulants and NSAIDs.

There is also some evidence that suggests saw palmetto may be linked to erectile dysfunction (ED). While the exact mechanism of action is unknown at this time, it is thought that the herb may interfere with the body’s ability to produce adequate amounts of testosterone.

Kidneys & Liver Damage

At this time there is no evidence to suggest that saw palmetto can damage either the kidneys or liver when taken in recommended doses.

Additionally, studies have not found any connection between saw palmetto and increased testosterone levels in men.  In fact, it may interfere with the body’s ability to produce adequate amounts of testosterone.

However, if you have a pre-existing condition or are taking certain medications then it’s best to consult your doctor before taking saw palmetto supplements.

The daily recommended dose for saw palmetto varies depending on factors such as age and health status. Generally speaking, adults should take 320mg - 960mg of standardized extract per day for optimal results.

Who Should Not Take It

Women who are pregnant or breastfeeding should avoid taking saw palmetto as its safety has not been established during these times.

Additionally, people who suffer from bleeding disorders should not take this supplement as it may increase their risk of bleeding complications.

Furthermore, those who are allergic to plants belonging to the Arecaceae family (e.g., coconut palms) should also avoid taking this supplement due to potential allergic reactions.  


Saw palmetto is a popular herbal supplement with many potential benefits including reducing prostate enlargement symptoms and improving urinary function among others.

However, there are some potential side effects associated with taking this supplement including nausea and headache which could lead to further complications if left untreated.

Additionally, there is some evidence linking saw palmetto use to erectile dysfunction although the exact mechanism of action remains unknown at this time.

All in all though – while there are some possible drawbacks – research shows that overall most people who take Saw Palmetto experience positive benefits without any serious negative side effects! Full steam ahead!
