Hair loss is a common condition that can be caused by a variety of factors, including genetics, certain medical conditions, hormonal changes, and the use of medications, such as stimulants and blood thinners (1Trusted Source).Saw palmetto is often used to balance hormone levels and combat hair loss. According to one review, saw palmetto may help block the activity of 5-alpha reductase (5α-R), an enzyme that converts testosterone into a hormone linked to hair loss called dihydrotestosterone (DHT).

2. Improves urinary tract function

Urinary tract symptoms are common among older men and can include issues like incontinence and difficulty urinating. Saw palmetto may improve urinary symptoms associated with benign prostate hyperplasia (BPH) — a condition that causes an enlargement of the prostate gland and results in decreased urine flow.

3. May support prostate health

The prostate is a small gland located between the bladder and the penis in men, which is responsible for maintaining sperm health. Some research suggests that saw palmetto could support prostate health and may aid in preventing issues like BPH and prostate can-cer.

4. May decrease inflammation

Saw palmetto contains the antioxidants epicatechin and methyl gallate — compounds that prevent damage to cells, decrease inflammation, and protect against chronic disease. Some research shows that saw palmetto may have anti-inflammatory properties, which could be beneficial in treating certain conditions.

Although these results are promising, additional studies are needed to determine how saw palmetto may impact inflammation in humans.

5. May help regulate testosterone levels

Saw palmetto is often used by men looking to boost testosterone levels naturally.

Regulating testosterone levels can impact several aspects of health, including body composition, sex drive, mood, and cognition (17Trusted Source).

Testosterone levels decline with age, and some research shows that low levels of testosterone could contribute to conditions like heart disease.
