Modafinil does not directly increase metabolism; instead, it is generally used to increase alertness and decrease daytime drowsiness. Modafinil Modalert 200mg has little influence on metabolism, despite having certain stimulant-like effects including heightened alertness and enhanced cognitive performance. Although mild elevations in blood pressure or heart rate may occur in certain users, which may have an indirect impact on metabolic processes, these side effects are not severe enough to be regarded as the drug's main activity. Before using modafinil, it's crucial to talk to your doctor about any adverse effects or metabolic changes you may be worried about.
