L-theanine helps improve the body’s tolerance to stress and cultivate total emotional health. This amino acid supports balanced levels of the inhibitory neurotransmitters serotonin, GABA, and dopamine. Inhibitory neurotransmitters help reduce rapid transmission of nerve impulses which can cause health problems. Excessive nerve impulse transmission has been linked to convulsive disorders, agitation, and hyperactivity in children. By preventing neurotransmitter deficiencies, L-theanine may also help with emotional problems due to inadequate levels of these important brain chemicals like depressed mood and anxiousness. Healthy serotonin, GABA, and dopamine levels naturally create the feelings of relaxation and calmness, especially during stress. L-Theanine benefits people who are always on the go and are always stressed out from a fast paced lifestyle. It may also help women achieve a healthier mood during PMS and menopause, in which they usually suffer from discomforts and mood swings. By promoting adequate rest periods, L-theanine helps in producing healthy energy levels. Enough rest also rejuvenates and refreshes the different organs of the body for maximum functioning. Pure theanine supports mental clarity and enhances concentration. Regular users of caffeinated products will greatly benefit from the inhibitory action of L-theanine in controlling the stimulatory effects of caffeine. L-theanine may also support normal blood pressure and improve the body’s natural immune response.

Source Naturals L-Theanine is a special formulation of L-theanine, an amino acid that works primarily on the neurotransmitters of the brain. Neurotransmitters are chemicals released in the brain cells or neurons responsible for many vital body processes. L-Theanine acts on the neurotransmitter gamma-aminobutyric acid (GABA), serotonin, and norepinephrine. L-Theanine acts by increasing GABA levels created by the body and distribute it to the parts of the brain. GABA is known for naturally producing a calming feeling. On the other hand, L-theanine also boosts serotonin production and distribution in the bloodstream. Serotonin is responsible for elevating the mood and controlling negative emotions like anger. When there are higher levels of serotonin in the body, it may counteract depressed mood and agitations. While L-Theanine increases both GABA and serotonin, it further helps the body by decreasing the neurotransmitter Norepinephrine. Norepinephrine is released when the body undergoes a “fight or flight” status. During this time, there is a hyperactivity of some body systems including the heart and its blood vessels. Increased norepinephrine causes higher blood pressure levels. As an L-theanine supplement, Source Naturals L-Theanine will not just help you relax, increase your mental alertness, and give you a happier mood. It will also support healthy blood vessels and heart functions.
