It is not recommended to take capsules with high levels of caffeine like ENERGEX PLUS if you suffer from mood problems, anxiety, or stress, as caffeine can worsen these conditions. It is advised to choose a product with lower caffeine content or a caffeine-free multivitamin instead. If you decide to take ENERGEX, it is recommended to limit its use to one month and consult a doctor if persistent fatigue, lack of energy, or anxiety occur. Be aware of potential interactions with medications like Citalopram, such as St. John's Wort, and always seek information before starting a new product.
