What Are the Most Common Tribulus Side Effects?
The most common tribulus side effects may include an upset stomach, nausea, and an enlargement of the prostate gland. Tribulus may affect hormone levels in the body, which could lead to mild side effects, such as a change in voice, or more serious ones including an increased risk of cancer. In general, tribulus is considered to be safe, however, and these side effects are usually limited to only a small percentage of users.
