Saw Palmetto


Saw Palmetto extract is a natural product that contains fatty acids and sterols containing stigmasterol and beta-sitosterol. It is a known ingredient in supplements that promote prostate health.


Reported Effects

1) May boost natural testosterone levels.

2) Might help with prostate problems

3) May boost immune system


Saw palmetto is a popular supplement that allegedly decreases and improves the symptoms of enlarged prostate, although this has been disputed by reputable sources that have carried out active research.

The extract can be used for prostate infection treatment. Some people also use saw palmetto as a remedy for colds, sore throats, asthma, coughs, and migraine attacks. It has also been used as a traditional medication for various urinary and reproduction issues.

These effects, as aforementioned partially, have not been strongly backed up by medical research, and continuous studies are still being conducted to determine effectiveness, as well as safety in use. Other reported effects include:

1. Prevention of prostate cancer.

2. Some men think that the product helps them grow hair, and have reported thicker and healthier hair growth. This is especially the case with men who previously had baldness issues or hair problems.

3. Relief for chronic bronchitis.

4. Increased breast size for women.

5. Reduced bleeding after prostate surgery.

6. Possibility of use in cancer treatment.


Possible Dangers

There may be some minor side effects as well as allergic reactions to saw palmetto use, specifically gastrointestinal. It has been associated with an increased incidence of bleeding and even impacts sex hormones. Heart disease may also increase because of the chemical beta-sitosterol. It has properties similar to cholesterol and may have harmful effects at certain levels.

Saw palmetto is also not recommended during pregnancy, and while breast feeding. However, being a natural product, it is likely safe for most users. Adverse side effects are not usually serious, but there are also claims of the following effects on rare occasions:

1. People complain about dizziness.

2. Headaches have also been reported.

3. For some users, vomiting and nausea have been directly associated with use of the product.

4. People with weak stomachs may also experience diarrhea or constipation

5. Impotence.

6. Liver and pancreas problems.


FDA approval

Saw palmetto is not FDA approved for treatment of any disease, and not evaluated for safety or effectiveness. It should not be used as a substitute for prescription. Manufacturing standards have also not been regulated and may have a risk of contamination with toxic elements or other compounds.



Saw palmetto has not shown to tremendously reduce urinary tract symptoms according to a 2001 published in the Journal of the American Medical Association. It covered 269 subjects, and while there was a 2.20 drop in the American Urological Association Symptom Index score of the men in the saw palmetto group, the subjects in the placebo group showed a 2.99 point drop.

Reviews made by the National Center for Complementary and Alternative Medicine, on the other hand, found no notable differences in the treatment for benign prostatic hyperplasia comparing saw palmetto with placebo.

3. John Scott’s Nitro Test2

4. Vigor Labs Ball

Saw Palmetto has been widely used as a potential treatment for prostate issues, but should not be used to replace scientifically proven treatments or medication. Most of the claimed effects have not been backed up by medical research, which means that it is most likely not the solution you are looking for.

At best, saw palmetto may be used as a supplement, bearing in mind that there may be harmful effects for certain people. Trimethylglycine is another active ingredient that is recommended by most users.
