Balanced Mood Support By GNC Total Lean Overview & Drug Interactions

Passionflower (Passiflora incarnata) is a climbing vine with fragrant white and purple flowers that is native to the Americas. It is purported to have a number of potential health benefits, including reducing anxiety and improving sleep. It is thought to work by increasing the levels of GABA (gamma-aminobutyric acid), a neurotransmitter in the brain that helps regulate mood and anxiety. Passionflower may also have mild sedative and muscle-relaxing effects and may be helpful in the treatment of muscle spasms and other muscle disorders. Dietary supplements containing passionflower are generally standardized to contain no less than 1.5% of the flavanoid vitexin.

Rhodiola is a type of plant native to the Arctic regions of Europe and Asia. It is also known as "golden root" or "arctic root." The roots and rhizomes of Rhodiola are commonly used in dietary supplements for their purported effects as an 'adaptogen', which are used to improve physical and mental performance, reduce fatigue, and enhance the ability to cope with stress. Rhodiola is believed to work by increasing the production of certain chemicals in the brain (e.g., serotonin, dopamine, and norepinephrine) that are involved in mood and energy regulation. Rhodiola supplements are often standardized to a specific amount of their rosavin and salidroside content.

Theanine, often referred to as L-theanine as that is the predominant isomer of theanine, is an amino acid commonly found in tea leaves, particularly in green tea. It is purported to increase levels of GABA, serotonin, and dopamine in the brain, which can help to reduce stress and anxiety. L-theanine may also promote a sense of calm and improve overall well-being. Some studies have also suggested that it may improve cognitive function, although more research is needed. Most reported drug interactions with theanine are due to its sedative effects.
