GNC Preventive Nutrition
Overview
Tri-Sleep combines several ingredients known for their potential to promote relaxation and improve sleep. While individual components have shown promise in clinical studies, the long-term effectiveness of this specific formulation requires more research. The supplement is formulated in a layered approach, which is not particularly relevant when all ingredients are consumed simultaneously. The use of proprietary blends makes it impossible to assess if the ingredients are present at clinically effective levels.
