EPA and DHA from fish oil promote cardiovascular health by supporting healthy triglyceride and lipid metabolism, maintaining healthy blood flow, and supporting healthy platelet function. Fish oil is also important for optimal joint function. It maintains healthy prostaglandin and leukotriene production, which is important for maintaining connective tissue health and comfort. Furthermore, omega-3 fatty acids are important components of neuronal cell membranes and are essential to cognitive function. By supporting vascular health, fish oils promote oxygen and nutrient delivery to the brain. Studies suggest that healthy red blood cell membrane omega-3 fatty acid concentration is associated with emotional well-being. Both epidemiological and double blind placebo-controlled trials indicate that fish oil supports positive mood.

Green tea has been recognized for centuries as having relaxant properties. l-Theanine, a unique amino acid derived from tea, provides the characteristic taste of green tea. l-Theanine has also been discovered as the biologically active constituent of green tea responsible for promoting relaxation. In a preliminary non-clinical study, an l-theanine solution enhanced alpha wave production in the occipital and parietal regions of the brains of volunteers. These observed patterns are considered to be an index of relaxation. Furthermore, it did so rapidly and without causing drowsiness. In two additional studies, alpha waves were also shown to be detectable soon after l-theanine administration. Theanine is also useful for supporting healthy cellular function. Preliminary research suggests that l-theanine may be helpful for premenstrual support including healthy mood. Furthermore, theanine has been reported to moderate the effects of caffeine on the central nervous system. l-Theanines safety is supported in studies and by its long history of safe consumption in tea. Pure Encapsulations l-Theanine is Suntheanine®, the brand which has been used in scientific studies.
