Benefits Of Nettle Leaf: Nettle Leaves and Testosterone

Testosterone is a vital hormone that plays a significant role in the development and maintenance of various bodily functions in both men and women. It is responsible for regulating muscle mass, bone density, libido, mood, and overall well-being. Therefore, maintaining optimal testosterone levels is essential for overall health and vitality.

In recent years, there has been growing interest in the potential benefits of natural substances, such as nettle leaf, for supporting testosterone levels. Nettle leaf, derived from the stinging nettle plant (Urtica dioica), has gained attention for its potential role in testosterone regulation. It’s also been studied for its effects on organ health, inflammation, and allergies.

Exploring the Benefits of Nettle Leaf for Testosterone

Firstly, it’s important to state that most of the scientific research shows that nettle leaf does not raise testosterone levels, but could play a role in improving free testosterone. Free testosterone is the amount of the hormone that your body has available to work with that isn’t currently bound to other cells. That means that it’s essentially the “effective” testosterone that you’re working with.

That means the main mechanism by which nettle leaf may “increase” testosterone is to reduce testosterone binding to proteins in the bloodstream. With the main two bioactive compounds that may contribute to nettle leaves potential effects on testosterone levels being  lignans and beta-sitosterol. Although there are a couple of other ways in which it could alter testosterone levels.

And it seems nettle leaf has 3 key ways in which it benefits men’s health:

1. Prostate Health Support: The prostate gland is sensitive to hormonal changes, particularly testosterone. Nettle leaf has been traditionally used to promote prostate health and may contribute to the well-being of this important gland. There’s a reasonable amount of evidence to suggest that nettle leaf does have a positive effect with several large trails having cited improvements in urinary tract issues and demonstrated a reduction in size for swollen prostates, the largest being a double blind controlled study of 558 men [1], several trials have also recorded data after the end period and displayed no increased risk of long term side effects of nettle leaf extract. [2] And further trials have confirmed the results. [3][4] And whilst this is enough of a health benefit in and of itself, an enlarged prostate directly decreases testosterone levels. And testosterone levels have been shown to be directly inverse relationship to prostate size. [5] Although it should be noted that the large study we previously mentioned observed no difference to overall testosterone levels despite the positive impacts on prostate size. [1]

2. Reducing Testosterone Binding: Nettle leaf contains compounds that can inhibit the binding of testosterone to sex hormone-binding globulin (SHBG), [6] a protein that circulates in the bloodstream. By reducing this binding, nettle leaf may help increase the levels of free testosterone, which is the biologically active form that can exert its effects on the body.

a. Lignans: Nettle leaves are rich in lignans, which are a type of polyphenol. Studies have suggested that lignans may play a role in reducing the binding of testosterone to sex hormone-binding globulin (SHBG), a protein that circulates in the bloodstream and can bind to testosterone, rendering it inactive. By reducing this binding, nettle leaf lignans may help increase the levels of free testosterone, which is the biologically active form. Increasing free testosterone results in an increase in the effects of testosterone without requiring an increase in testosterone production.[7]

b. Beta-Sitosterol: Another significant compound found in nettle leaves is beta-sitosterol, a plant sterol with structural similarity to cholesterol. Beta-sitosterol has been studied for its potential to modulate testosterone metabolism. It may help inhibit the conversion of testosterone to dihydrotestosterone (DHT), [8] a potent androgen that can contribute to conditions such as benign prostatic hyperplasia (BPH) in men.

3. Flavonoids: Chronic inflammation can disrupt hormone balance, including testosterone regulation. Nettle leaf contains flavonoids and other bioactive compounds with anti-inflammatory and anti-oxidant properties. [9] These can affect testosterone levels by:

a. Increasing the production of steroidogenic acute regulatory protein (StAR) which is essential for cholesterol to enter the mitochondria, which in turn allows for increased testosterone production in the Leydig cells. However, any effect in this regard seems to be minimal from the specific flavonoids in nettle leaf extracts. Flavonoids having a 5,7-dihydroxychromen-4-one structure [10] seem to be more effective.

b. By reducing inflammation, nettle leaf may support overall hormonal health and contribute to the optimization of testosterone levels. However, nettle leaf has shown to be relatively ineffective in treating osteoarthritis [11] [12] and other chronic inflammatory conditions. Meaning there are far better natural anti inflammatory compounds, such as curcumin or gingerol than the specific flavonoids in nettle leaf. However, in healthy individuals the effects of flavonoids can also lead to improvements in athletic pursuits which often leads the general public using nettle leaf to perceive improved muscular recovery times and attribute that to an increase in testosterone.

Can Nettle Leaf Raise Testosterone Levels? 

Nettle leaf contains compounds such as lignans and beta-sitosterol that seem to impact free testosterone levels. The ability of nettle leaf compounds to reduce testosterone binding to proteins, exhibit anti-inflammatory effects, and modulate enzymes involved in testosterone metabolism suggests a potential role in testosterone optimization.

Research suggests that nettle leaf does not raise overall testosterone levels, except in the case where it is responsible for a reduction in prostate size, but this evidence is mixed.

The evidence that nettle leaf is beneficial for prostate health is strong.

However, further research is necessary to elucidate the precise mechanisms and evaluate the long-term effects of nettle leaf on testosterone levels. As with any dietary supplement or intervention, it is always advisable to consult with a healthcare professional before incorporating nettle leaf or any other natural remedy for testosterone optimization.

Dosage Considerations and Guidelines for Nettle Leaf Supplements

When using nettle leaf supplements for testosterone enhancement, it is important to follow dosage recommendations to ensure safety and effectiveness. Consider the following guidelines:

  • Recommended Nettle Leaf Dosage For Testosterone: For testosterone the most well regarded study suggested that 120mg three times a day is effective, most other studies rely on a similar amount. Thus a minimum of 300mg/day is recommended. This is the same dosage as suggested for prostate issues. [1]
  • Recommended Nettle Leaf Dosage For Allergies: 200mg a day is the most studied dosage for nettle leaf as a treatment for allergies. However, it should be noted that there is less scientific evidence to support it’s use for allergies than it’s impact on hormones.
