You know serotonin is important for mood, but did you know it also supports immune function? If immune cells are cars, serotonin is a traffic copy; it directs them to travel to troubled areas in the body. Serotonin also modulates the release of cytokines, which help coordinate a response to immune threats. In that way, serotonin directly impacts immune function.

But serotonin also indirectly supports immunity, because it helps you manage stress, maintain a positive mood, and enjoy restful sleep — all key for a strong immune system.

PureBalance™ Serotonin includes 5-HTP, the raw material your body uses to make serotonin.* The actions of serotonin are reinforced with ingredients for:

• Immunity: Vitamin D supports overall immunity and helps promotes upper respiratory tract health.*
• Stress management: Rhodiola rosea helps the body adapt to stress, while L-theanine calms the brain.* Relora® may also reduce stress and stress-related eating.*
• Mood support: Insufficient vitamin D may negatively affect mood, while Rhodiola rosea has been used for centuries to promote a positive outlook.*
• Sleep support: L-theanine encourages the transition from the beta brain waves of mental arousal to the alpha brain waves of relaxation.*
