The Connection Between Protein and Brain Health: How Amino Acids Affect Your Mood and Cognition

By now, you should know that protein is an essential nutrient for building and repairing muscle, but did you know that it's also crucial for brain health? Amino acids, the building blocks of protein, play a vital role in maintaining the health and function of your brain. Here, we'll explore the connection between protein and brain health, and how specific amino acids can affect your mood and cognitive abilities.

The Brain-Body Connection

Your brain and body are connected in many ways, and one of the most important connections is through the foods you consume. The food you eat provides the building blocks for the cells in your body, including your very important brain cells. Your brain is made up of about 60% fat and 20% protein, which means that protein is a critical nutrient for maintaining brain health.

Amino Acids and Neurotransmitters

Amino acids are the building blocks of protein, and they're essential for the production of neurotransmitters in your brain. Neurotransmitters are the chemical messengers that allow your brain cells to communicate with each other. There are a few key neurotransmitters that are affected by amino acids, including:
  • Dopamine: This neurotransmitter is involved in motivation, reward, and pleasure. It's made from the amino acid tyrosine.
  • Serotonin: This neurotransmitter is involved in mood, appetite, and sleep. It's made from the amino acid tryptophan.
  • GABA: This neurotransmitter is involved in relaxation and reducing anxiety. It's made from the amino acid glutamate.
Amino Acids and Your Mood

Because amino acids are involved in the production of neurotransmitters, they have a significant impact on your mood. One example is, low levels of the amino acid tryptophan can lead to a decrease in serotonin production, which is associated with depression and anxiety. On the other hand, boosting your intake of tryptophan through your diet or supplements can help boost your mood.

Other amino acids, like tyrosine, can help improve focus and concentration. This is because tyrosine is used to produce dopamine, which is involved in motivation and attention to detail. Increasing your intake of tyrosine can help improve cognitive function and reduce mental fatigue.

Amino Acids and Cognition

In addition to affecting mood, amino acids can also have an impact on cognitive function. For example, the amino acid glutamine is involved in the production of glutamate, which is an excitatory neurotransmitter that's important for learning and memory. Increasing your intake of glutamine can help improve cognitive function and support brain health.

Other amino acids, such as arginine and citrulline, can help improve blood flow to the brain. This is because they're involved in the production of nitric oxide, which helps dilate blood vessels and improve circulation. Improving blood flow to the brain can help improve cognitive function and reduce the risk of cognitive decline.

In conclusion, protein is an essential nutrient for building and repairing muscle, but it's also crucial for maintaining healthy brain function.  Amino acids, the building blocks of protein, are involved in the production of important neurotransmitters that affect mood and cognition. By increasing your intake of specific amino acids, you can support brain health and improve your mood, focus, and cognitive function. So the next time you're planning your meals, make sure to include plenty of protein-rich foods and protein shakes (like Legacy FRESH) to support your brain health.
