                                Multiple medical sources, including WebMD, indicate that taking lysine in doses up to 3000 mg daily for up to one year is considered possibly safe for most people. Understanding how long is it safe to take lysine requires weighing its therapeutic benefits against the potential side effects and risks associated with prolonged, high-dose usage.
