What is Saw Palmetto?
Saw palmetto (Serenoa repens) is a shrub-like palm that too grows best in warm regions of the United States of America, Florida in particular. Its berries contain useful chemicals that have been applied using traditional knowledge of Native Americans for different illnesses.
Nowadays, these berries have finally found their place in the arsenal of folk remedies, although for quite a different purpose: to maintain the health of the prostate gland and decrease inflammation.
Saw Palmetto Benefits for Men
May Improve Urinary Tract Function
Saw palmetto extract (SPE) has been studied for its potential to alleviate lower urinary tract symptoms (LUTS), particularly in individuals with benign prostatic hyperplasia (BPH).
Some research suggests that SPE may improve urinary symptoms by affecting pharmacological receptors in the lower urinary tract.
May Support Prostate Health
Saw palmetto is commonly used to treat symptoms of benign prostatic hyperplasia (BPH). However, the studies and reviews have found it to be no more effective than a placebo in treating urinary symptoms related to BPH.

May Help Regulate Testosterone Levels
Saw palmetto may influence testosterone levels by inhibiting 5-alpha reductase, the enzyme responsible for converting testosterone into dihydrotestosterone (DHT).
By reducing DHT levels, saw palmetto could help maintain higher testosterone levels in the body, potentially benefiting conditions linked to hormonal imbalances.
Dr. Robert Applebaum
According to Dr. Robert Applebaum, a plastic surgeon in Beverly Hills, saw palmetto can stabilize testosterone levels by reducing the activity of 5-alpha reductase, which is an enzyme that converts the hormone into DHT. In addition, it can also aid by decreasing the uptake of DHT by reducing its ability to bind with androgen receptors. So while the jury is still out, there is some attractive data on its ability to help with testosterone levels.
May Prevent Hair Loss
Saw palmetto has shown promise in reducing hair loss, particularly in androgenetic alopecia. It is believed to inhibit the 5-alpha reductase enzyme, thereby reducing DHT levels, which are associated with hair follicle shrinkage.
Some studies have reported improvements in hair density and quality with saw palmetto supplementation.
May Help Reduce Inflammation
Saw palmetto exhibits anti-inflammatory properties, which may contribute to its therapeutic effects. Research indicates that it can downregulate pro-inflammatory cytokines like IL-6 and IL-17, potentially reducing inflammation in conditions such as BPH.
May Support Libido and Fertility
Traditionally, saw palmetto has been used to enhance sexual vigor and increase sperm production. While historical use suggests benefits for libido and fertility, more rigorous scientific studies are needed to confirm these effects.
May Have Anti-Cancer Effects
In vitro studies have found that saw palmetto inhibits the growth of prostatic cancer cells and may induce apoptosis. However, more clinical research is necessary to determine its effectiveness in reducing prostate cancer risk in humans.
May Help With Chronic Pelvic Pain
Saw palmetto extract has been studied for its potential to alleviate symptoms of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). While some studies suggest benefits, results are mixed, and further research is needed to establish its efficacy in this context.
Saw Palmetto Benefits for Women
Generally, saw palmetto supplements are taken by males; however, females can receive some gain from the plant since this substance may regulate hormones.
Similar to men, saw palmetto can benefit women health by inhibiting testosterone conversion to DHT and modulating prolactin levels. This may help address PCOS symptoms like irregular periods, excess facial hair, and fertility issues.
For post-menopausal women, the extract may reduce hot flashes, mood swings, and unwanted facial hair caused by elevated DHT levels.
Saw palmetto may also combat female pattern hair loss by blocking 5-alpha reductase enzyme activity, with topical application showing improved hair density.
The extract's antioxidant compounds provide skin benefits through reduced inflammation and acne prevention, while research demonstrates urinary health improvements, including reduced daytime urination frequency and better bladder function in women with age-related incontinence.

How Does Saw Palmetto Work?
Saw palmetto's effects come from a unique blend of natural compounds, primarily found in its berries. These active ingredients support a range of potential health benefits, particularly for hormone balance and inflammation.
Among the standout components are:
Phytosterols – Plant-based molecules that may influence hormone activity by interacting with androgen receptors, including those affected by testosterone.
Flavonoids – Known for their antioxidant and anti-inflammatory properties, these compounds help shield your cells from oxidative stress and may ease inflammation.
Fatty Acids – Saw palmetto contains beneficial fatty acids such as caprylic, lauric, palmitic, and oleic acids. These contribute to reducing inflammation and may also assist in promoting healthy nerve signals.

Forms of Saw Palmetto & Their Benefits
Saw Palmetto Tea

Health Benefits: The tea supports urinary tract health, reduces inflammation, and offers a milder way to enjoy the benefits of saw palmetto.
Saw Palmetto Berries
Nutritional Content and Uses: Fatty acids and phytosterols found in the berries enhance health. It is therefore justified to conclude that berries are a combination of good health-benefiting properties. They are usually eaten whole, dried, or processed into tablets/supplements.
Capsules and Tablets:
These are the most common supplement forms that provide a higher concentration of saw palmetto extract. Available in standardized dosages, these saw palmetto supplements offer convenient daily intake and consistent potency for therapeutic benefits.
Saw Palmetto Recommended Dosages

Who Should Avoid Saw Palmetto?
Saw palmetto may have benefits, but it's not for everyone. Some should avoid it or consult a doctor first.
- Individuals with hormone-sensitive cancers: Saw palmetto may affect estrogen and testosterone levels, so those with hormone-related cancers like breast or prostate cancer should consult their doctor first.
- Pregnant or breastfeeding women: Research on saw palmetto during pregnancy or breastfeeding is limited, so it’s safest to avoid it.
- Children: Saw palmetto studies focus mainly on adults, especially men with BPH. Since there’s little information on its effects in children, it’s best to keep it out of their reach.
Does Saw Palmetto Really Work?
The history of using saw palmetto as an herbal remedy goes back far in time, and even today many specialists prefer this product as part of a comprehensive wellness plan.
However, recently the interest in its potential for women is growing. There is some evidence of positive results for the treatment of female pattern hair loss, PCOS and other ailments associated with high levels of androgens. Further investigations are needed, but the current results look promising.
One useful information about the use of saw palmetto as an ingredient to prevent hair loss in women is the fact that this product cannot be applied as a separate remedy.
The approach to the treatment in traditional herbal medicine always implies a more holistic approach by taking into account all the aspects of patients' lives and combining proper herbs, nutrition, and healthy lifestyle.
This is why most of the good quality saw palmetto hair supplements include some additional ingredients that help maintain proper testosterone metabolism and hormonal balance.
If you want to try saw palmetto supplements for women or hair loss in general, opt for a well-balanced formula that combines saw palmetto with other supportive ingredients.
Side Effects and Interactions
Saw palmetto is generally well-tolerated, but may cause mild side effects in some people, including:
- Dizziness
- Headache
- Nausea
- Diarrhea
- Blood Thinners: Saw palmetto can increase the risk of bleeding, especially when taken with blood thinners.
- Hormone-related Therapies: It may interact with medications that affect hormone levels.
On the safety of saw palmetto, although no serious side effects were reported when taken for short periods, there is limited information about the proper long-term effects. However, it is advisable to consult a healthcare provider before introducing any new supplement, particularly for long-term usage.

Who Shouldn't Take Saw Palmetto?
Now let's consider the people for whom it might be undesirable to try saw palmetto as a treatment option.
People with hormone-sensitive cancers: Saw palmetto may affect hormone levels, such as estrogen and testosterone. Individuals who have breast cancer or prostate cancer are advised against the intake of saw palmetto without consulting a doctor first.
Pregnant women and those breastfeeding: There is insufficient data regarding the safety of taking saw palmetto during pregnancy. Moreover, it remains unknown whether saw palmetto enters breast milk; hence, its complete avoidance would be the wisest decision.
Children: Most of the studies of saw palmetto products have been done on adults only. As there is no sufficient information about the influence of saw palmetto on children, it is advisable not to use this herb at all.
Can You Take Too Much?
Saw palmetto is generally considered safe and well-tolerated by most men. It is not known to be highly toxic, which is one reason it remains a popular choice for natural prostate support and BPH symptom relief.
That said, more is not always better. Taking higher doses than what is listed on the label is not a good idea unless your doctor tells you otherwise. Sticking to the recommended saw palmetto dosage is the safest approach.
If you are thinking about taking saw palmetto supplements for prostate health, have a quick conversation with your doctor first especially if you are already on other medications. They can help you figure out the right amount for your situation.
What Should You Look For?
There are several points that one should think about before you start using saw palmetto:
First, saw palmetto supplements are not suitable for everybody because they can have some negative interaction with other medications, thus, one should always talk to one's doctor before taking these supplements.
Second, active substances of saw palmetto berries cannot be consumed with water, therefore, one should never consume saw palmetto in the form of tea. Instead, one had better purchase a high-quality saw palmetto supplement.
If you want to gather saw palmetto berries by yourself, remember that you need some permission to collect saw palmetto berries in Florida.
You had better purchase a high-quality prostate health supplement and consult your doctor about its consumption.
