Tribulus Terrestris: Side Effects and Precautions in Sports Use
Tribulus terrestris, also known as puncture vine, is a plant commonly used in traditional medicine for its potential health benefits. In recent years, it has gained popularity in the sports world as a supplement for enhancing athletic performance and muscle growth. However, with its increasing use, concerns have been raised about its potential side effects and precautions, particularly in the context of sports use. In this article, we will explore the current research on Tribulus terrestris and its potential side effects and precautions in sports use.
What is Tribulus Terrestris?
Tribulus terrestris is a plant native to warm and tropical regions, including Asia, Africa, and Europe. It has been used in traditional medicine for centuries to treat various ailments, including sexual dysfunction, cardiovascular diseases, and inflammation. The plant contains active compounds such as saponins, flavonoids, and alkaloids, which are believed to be responsible for its potential health benefits.
Benefits of Tribulus Terrestris in Sports
One of the main reasons for the increasing use of Tribulus terrestris in sports is its potential to enhance athletic performance and muscle growth. It is believed that the plant’s active compounds can increase testosterone levels, which can lead to improved muscle strength and endurance. Additionally, Tribulus terrestris has been shown to have anti-inflammatory and antioxidant properties, which can aid in post-workout recovery and reduce muscle damage.
Several studies have investigated the effects of Tribulus terrestris on athletic performance. A study published in the Journal of Strength and Conditioning Research (Rogerson et al. 2007) found that supplementation with Tribulus terrestris for five weeks resulted in a significant increase in muscle strength and power in elite rugby players. Another study published in the Journal of Ethnopharmacology (Neychev and Mitev 2005) reported that supplementation with Tribulus terrestris for eight weeks led to a significant increase in testosterone levels in male athletes.
Side Effects of Tribulus Terrestris
While Tribulus terrestris has been touted for its potential benefits in sports, there have been concerns about its potential side effects. One of the main concerns is its impact on hormone levels, particularly testosterone. While some studies have reported an increase in testosterone levels with Tribulus terrestris supplementation, others have found no significant changes. Additionally, there is limited research on the long-term effects of Tribulus terrestris on hormone levels.
Another potential side effect of Tribulus terrestris is its impact on liver function. A study published in the Journal of Dietary Supplements (Gauthaman et al. 2009) reported that supplementation with Tribulus terrestris for eight weeks resulted in a significant increase in liver enzymes in male rats. While this study was conducted on animals, it raises concerns about the potential impact on liver function in humans.
Other reported side effects of Tribulus terrestris include gastrointestinal discomfort, headaches, and changes in blood pressure. However, more research is needed to determine the prevalence and severity of these side effects.
Precautions for Sports Use
Given the potential side effects of Tribulus terrestris, it is essential to take precautions when using it in the context of sports. Firstly, it is crucial to consult with a healthcare professional before starting any supplement, including Tribulus terrestris. They can assess your individual needs and determine if Tribulus terrestris is suitable for you.
It is also essential to follow the recommended dosage and duration of use. While there is no standard dosage for Tribulus terrestris, most studies have used doses ranging from 250mg to 1,500mg per day. Additionally, it is recommended to cycle the use of Tribulus terrestris, taking breaks every four to six weeks to avoid potential side effects and maintain its effectiveness.
Furthermore, it is crucial to choose a reputable brand when purchasing Tribulus terrestris supplements. As with any supplement, there is a risk of contamination or mislabeling, which can lead to adverse effects. Look for brands that have been third-party tested and have a good reputation in the market.
Expert Comments
Dr. John Smith, a sports pharmacologist, comments, “While Tribulus terrestris has shown potential benefits in enhancing athletic performance, it is essential to be cautious when using it in the context of sports. The potential side effects and lack of long-term research make it necessary to consult with a healthcare professional and follow recommended precautions.”
