Enhanced Neurological and Nervous System Support* Recommended for mood support, sleep disturbances, poor libido and to maintain a healthy level of stress. MoodPlus™ features a carefully formulated combination of nutrients that function as neurotransmitters to support the overall nervous system and promote a healthy mood. Magnesium is important for vital cellular functions including cell proliferation and signal transduction. 5-HTP, SAM-e and DMAE are included for their important role in serotonin synthesis. 5-HTP and GABA have shown in research studies to enhance endorphin levels and result in a mood lightening effect as well as calming effect. MoodPlus™ includes 5-HTP which is a drug free amino acid derived from a plant that naturally increases the body's level of serotonin, the chemical messenger that affects emotions, behavior, appetite and sleep. Today's stress-filled lifestyles and diet regimens may negatively affect how the body handles serotonin.
