Don't let stress overload push you over the edge—get back in control with the advanced calming nutrition of Swanson Ultra GABAplex with L-Tyrosine & L-Theanine. When excessive stress has your feeling overwhelmed, GABAplex helps bolster healthy brain and nervous system function and lighten the burden so you can face life's challenges with confidence. This breakthrough formula starts with GABA (gamma- aminobutyric acid), an inhibitory neurotransmitter that helps put the brakes on runaway stress so you can remain calm and collected when the pressure's on. For additional central nervous system support, GABAplex also includes three amino acids—taurine, L-tyrosine and L-glycine—that serve as biochemical precursors for the formation of neurotransmitters that play vital roles in emotional wellbeing. To complement the activity of these nutrients, GABAplex also includes L- theanine, the "anti-stress amino" that works to promote mental and physical relaxation without impairing mental clarity. For optimal effectiveness, GABAplex is fortified with BioPerine®, a standardized black pepper extract that promotes efficient nutrient absorption in the GI tract. Combined, they provide state-of-the-art, broad-spectrum nutritional support for mental and emotional wellbeing during high-stress times.
