There is limited specific information available about the safety of L-arginine and L-ornithine supplements for children, particularly those as young as 15 years old. However, some general considerations can be made based on existing data about L-arginine:

1. Potential Safety: L-arginine is possibly safe when taken by mouth in children¹. This is when it is used appropriately and for short periods. There are no specific warnings against its use in children when taken as directed.

2. Ornithine Considerations: There is less specific information regarding L-ornithine supplementation in children, but it is generally suggested that amino acid supplements be approached with caution in this age group due to their effect on metabolism and growth.

3. Dosage and Monitoring: If considering supplementation, it is important to follow recommended dosages and to monitor the child for any adverse effects, especially gastrointestinal disturbances or issues with blood pressure.

4. Medical Consultation: It is crucial to consult with a healthcare provider before starting a 15-year-old on these supplements to ensure they are safe based on the child’s specific health profile and nutritional needs.

In summary, while some evidence supports that L-arginine can be safe for children when used appropriately, the combination with L-ornithine should be approached carefully, and professional medical advice is strongly advised¹².
