Carb-Edge By PureFormulas Overview & Drug Interactions

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.

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.
