What are the potential side effects of taking Zantrex Black?

Zantrex Black, a dietary supplement marketed for weight loss and energy enhancement, can have several potential side effects due to its stimulant content, primarily caffeine. Common side effects include increased heart rate, jitters, anxiety, insomnia, headaches, dizziness, and gastrointestinal distress such as nausea or diarrhea. Additionally, it may cause irritability and rapid heartbeat. Individuals with sensitivity to caffeine or other stimulants are more likely to experience these adverse effects. It's also important for users to consider the risk of caffeine overdose and interactions with other medications. Long-term use or high doses might lead to more severe complications, so one should always consult with a healthcare provider before starting any new supplement regimen.
