• In adults (≥18 years), the specified doses 1000, 2000, 2500, 2750 and 3000 mg/day L-lysine in food supplements are unlikely to cause adverse health effects.
• In adolescents (14 to <18 years), the specified doses 1000, 2000, 2500, 2750 and 3000 mg/day L-lysine in food supplements are unlikely to cause adverse health effects.
• In children (10 to <14 years), the specified doses 1000, 2000, 2500, 2750 and 3000 mg/day L-lysine in food supplements are unlikely to cause adverse health effects.
