Does Saw Palmetto Affect Testosterone in Men?

Testosterone is the hormone that, quite simply, makes men men. Testosterone starts forming in the body during adolescence, but to many guys’ dismay, it begins to taper off at the age of thirty years old.

Testosterone is responsible for many important functions in the male body, including the ability to grow facial hair, muscle growth, and a low, deep voice.

Having lower levels of testosterone is problematic for many men – it decreases sex drive,  weak erections, and also can contribute to less energy and at a certain point prevents you from being able to put on muscle mass.

But, is there a way to reverse or replenish falling levels of testosterone? In short: yes. While you’ll never be as young as you once were and your testosterone levels will never be as high as your younger years, using supplements can help replenish those levels to a higher level.

Oftentimes, we overlook natural remedies in place of synthetically made hormones. Instead, research has found on ingredient in particular to be highly effective: saw palmetto.

What is Saw Palmetto?

Saw Palmetto may be a new word for you. It’s not an ingredient that’s often mentioned in the everyday health world and it wouldn’t be too shocking if your primary care physician has never heard of this as opposed to big pharmaceutical drugs.

Quite simple, saw palmetto is a palm that’s native to the southeastern area of the United States. In order to make an extract, the little fruits the palm contains are harvested and converted into powerful extracts.

Saw palmetto is nothing new, and in fact, it has been renown for its uses for hundreds of years. Native Americans use to frequently use saw palmetto as a treatment for reproductive issues and urinary system malfunctions. Additionally, it has been used by Mayans and European settlers as a tonic, antiseptic and nerve sedative.

Saw palmetto is best known for its use in decreasing symptoms of an enlarged prostate (benign prostatic hypertrophy, BPH). According to many research studies, it is effective for this use.
