News & Research:

  • Glutamate in the brain has unexpected qualities, researchers show with new analysis method - Science Daily, 1/21/20 - "the brain regulates its signals using glutamate in more ways than previously realised. ... Glutamate, or glutamic acid, is found in proteins in food. It occurs naturally in meat, in almost all vegetables, and in wheat and soy. It is also used as a food additive to enhance flavours, for example in the form of MSG, or monosodium glutamate ... Glutamate is an amino acid, and an important part of our body. It is also a neurotransmitter which nerve cells use to communicate, and forms the basis for some of the brain's basic functions such as cognition, memory and learning. It is also important for the immune system, the function of the gastrointestinal tract, and to prevent microorganisms from entering the body" - See glutamic acid at Amazon.com.
  • Boosting glutamate reduces anxiety in monkeys - Science Daily, 2/4/19 - "Hannah Clarke and colleagues were able to make anxious monkeys more comfortable with an unfamiliar human, who wore different masks to conceal his or her identity, by increasing glutamate release in the anterior hippocampus. In response to an unexpected loud sound, increased hippocampal glutamate was associated with increased blood pressure, heart rate, and scanning of the environment -- all of which are part of a typical threat response and reduced in anxious individuals. These effects depended on functioning of area 25, implicating this brain region and its connection to the hippocampus as a promising target for reducing anxiety."
  • Glutamate plays previously unknown role in neuromuscular development - Science Daily, 9/20/16
  • Transcranial direct current stimulation raises glutamate levels in humans - Science Daily, 9/19/16
  • Glutamate: Essential food for the brain - Science Daily, 10/4/15 - "Devoid of the energy supplied by cerebral glutamate, the brain sends signals to the liver to requisition a compensatory proportion of glucose, at the expense of the rest of the body. This is why the transgenic mice also showed a growth deficit and muscle atrophy. "This clearly shows how the brain works in a just-in-time manner and that each percent of energy resources is essential for its proper functioning," highlights Professor Pierre Maechler. "If a part of this energy disappears, the brain serves itself first and the rest of the body suffers. The liver must then make more glucose by drawing upon muscle protein, resulting in loss of muscle mass. Knowing that the brain uses glutamate as an energy resource allows us to reflect on other ways to overcome a potential shortfall" - See l-glutamic acid at Amazon.com.
  • Component Of Vegetable Protein May Be Linked To Lower Blood Pressure - Science Daily, 7/6/09 - "Researchers found that a 4.72 percent higher dietary intake of the amino acid glutamic acid as a percent of total dietary protein correlated with lower group average systolic blood pressure, lower by 1.5 to 3.0 millimeters of mercury (mm Hg). Group average diastolic blood pressure was lower by 1.0 to 1.6 mm Hg" - See l-glutamic acid at Amazon.com.
