These compounds interact with our bodies in complex ways. Some may cause changes to hormone levels, while others could affect cell function.[6] However, the exact mechanisms of how these compounds work are not completely understood.
Purported Benefits and Uses
Athletic Performance
Many athletes use Tribulus terrestris with the aim of gaining a competitive advantage.[7] Some believe it can increase both strength and muscle mass, often based on the idea that Tribulus boosts testosterone levels.[8]
Research into these potential effects has produced varied results. Some studies have shown no significant change in testosterone levels or athletic performance, while others have indicated small benefits in certain individuals.[9] Further research is needed to determine definite conclusions.
Libido and Sexual Function
Tribulus has a long history of being used to enhance sexual health.[10] It has been used in traditional medicine systems to address various sexual health concerns, such as low libido and erectile dysfunction.
Modern research has investigated these claims. Some studies suggest Tribulus may improve sexual function in some groups, however, the findings are not conclusive.[11] Results can vary greatly between studies and different populations.
Other Potential Benefits
Researchers are exploring other potential health benefits of Tribulus. Some areas under investigation include:
- Blood sugar regulation
- Heart health

- Stomach pain
- Diarrhea
- Constipation
These digestive side effects may be caused by how Tribulus affects the digestive system.[12] The plant contains substances that may cause irritation of the stomach lining, potentially leading to discomfort or changes in bowel habits in some people.
Sleep Disturbances
Tribulus may affect sleep patterns in some users, and people have reported experiencing:
- Difficulty falling asleep
- Waking up during the night
- Feeling less rested after sleep
The reason for these sleep changes is not completely understood. It could be linked to how Tribulus influences hormone levels or the nervous system.[13] If you experience changes in sleep after starting Tribulus, consider adjusting the time of day you take it.
Hormonal Changes
Tribulus has the potential to influence hormone levels in the body, which is a primary reason why many people use it.[14] However, these hormonal changes can sometimes result in undesirable effects.
Men might experience:
- Mood swings
- Changes in sex drive
- Acne or oily skin
Women could potentially notice:
- Irregular periods
- Breast tenderness
- Changes in body hair growth
These effects are not common, but they are possible.[15] They often disappear if you stop using Tribulus. It is important to talk to a doctor if you notice unexpected changes in your body.
Severe Side Effects and Risks
Liver Function
There are some concerns about how Tribulus might impact the liver. Some case reports have linked Tribulus use to liver problems.[16] While these cases are rare, they are worth being aware of.
Symptoms of liver issues can include:
- Yellowing of the skin or eyes
- Dark urine
- Abdominal pain
- Fatigue
If you have any existing liver problems, it is important to use Tribulus cautiously. You should always consult with a doctor before starting any new supplement.
Prostate Health
The effects of Tribulus on prostate health are not clear. Some worry that it might worsen prostate conditions, while others believe it could be helpful.
Research in this area has produced conflicting results. Some studies suggest Tribulus might increase prostate size in animals, but human studies have not shown any clear negative effects.[17]
If you have prostate issues or are at high risk of developing them, it is important to talk to your doctor. They can help you evaluate the potential risks and benefits of using Tribulus.
Cardiovascular Concerns
Tribulus may influence heart health and blood pressure. Some studies suggest it might lower blood pressure, which sounds positive, but could be dangerous if you are already taking medication for high blood pressure.[18]
There are also some concerns about its effects on heart rhythm. A few case reports have connected Tribulus to irregular heartbeats, but these cases are very uncommon and may have alternative explanations.[19]
If you have heart problems or are taking heart medication, it is important to be cautious with Tribulus. Always make your doctor aware of any supplements you are using.
Drug Interactions
Tribulus can interact with various medications. These interactions may alter how the drugs work or increase the chances of experiencing side effects.[20] Awareness of these potential interactions is crucial.
Drug Class | Potential Interaction |
---|---|
Diabetes medications | May lower blood sugar too much |
Blood thinners | Could increase bleeding risk |
Blood pressure drugs | Might cause blood pressure to drop too low |
Steroid medications | May alter hormone effects |
It is essential to inform your doctor and pharmacist about all the supplements you are taking. They can help you to avoid potentially dangerous interactions.
Combining Tribulus with other supplements may also cause problems. Be especially cautious when using other herbs that affect hormone levels or blood sugar. When unsure, seek advice from a healthcare professional.
Special Precautions
Pregnancy and Breastfeeding
Pregnant women should avoid using Tribulus terrestris.[21] The herb might impact hormone levels in a way that could be harmful to a developing baby. There is insufficient research to determine if it is safe during pregnancy.
There is also limited information available regarding the safety of Tribulus while breastfeeding. It is best to avoid it during this time as well.[22] Substances in Tribulus could pass into breast milk, potentially affecting the infant’s health or development.
If you are pregnant, trying to conceive, or breastfeeding, it is advisable to avoid Tribulus. Instead, choose safer alternatives that have been extensively studied in these situations.
Pre-existing Conditions
Some health conditions make using Tribulus riskier. Individuals with the following issues should take extra precautions:
- Diabetes
- Hormone-sensitive cancers

To use Tribulus safely, consider the following:
- Choose a reputable brand with clear dosage information.
- Start with the lowest recommended dose.
- Monitor how you feel for a few weeks.
- Slowly increase the dose if needed and if no side effects occur.
- Never exceed the dose on the product label.
Remember, taking more is not always better. Higher doses increase the likelihood of side effects without necessarily improving any benefits.
Quality and Purity Concerns
The quality of Tribulus supplements can vary significantly. Unlike prescription medications, dietary supplements are not strictly regulated, which can lead to issues such as:
- Inconsistent amounts of active compounds between brands

Poor quality supplements may not work as expected and could even be harmful. When choosing a Tribulus product, look for the following indicators of quality:
- Third-party testing for purity and potency
- Clear labeling of ingredients and amounts
- Good manufacturing practices (GMP) certification
- Positive reviews from reputable sources
Consider brands that specialize in herbal supplements, as they often have more stringent quality control processes. Do not choose the cheapest option, as higher quality usually comes at a higher price.
Alternatives to Tribulus Terrestris
If you are unsure about using Tribulus, there are alternative options available. Many natural substances are promoted with similar benefits. Some might be safer or have more research supporting their effectiveness.
For boosting athletic performance, consider:
- Creatine
- Beta-alanine
- Protein supplements
For supporting sexual health, consider:

For general health and well-being, consider:
- Regular exercise
- Balanced diet rich in fruits and vegetables
- Adequate sleep and stress management
Always do thorough research on any supplement before you start using it. What works best can vary from person to person. Sometimes, changes to your lifestyle can be more effective than any supplement.
Monitoring and Managing Side Effects
If you decide to try Tribulus, pay close attention to any unusual changes in your body. Some side effects may be mild and resolve on their own, while others could indicate a more serious problem.
Steps to take if you experience side effects:
- Stop taking Tribulus immediately.
- Write down what symptoms you’re experiencing.
- Contact your healthcare provider for advice.
- If symptoms are severe, seek medical attention right away.
- Report the side effects to the supplement manufacturer.
Do not ignore side effects hoping they will disappear. It is better to be careful with your health. If Tribulus does not suit you, there are numerous other ways to support your health and wellness goals.
