Apart from improving sleep quality, L-theanine offers a host of benefits for overall health and well-being.
Key Health Benefits of L-Theanine:
- Reduces Stress and Anxiety:
L-theanine is known for its ability to increase relaxation and reduce stress levels. It does this by increasing levels of the neurotransmitters GABA, dopamine, and serotonin, which are associated with reducing anxiety and promoting relaxation.
- Enhances Brain Function:
Many people drink green tea while working to improve their focus. This is because L-theanine has been shown to improve cognitive function, memory, and focus. It is due to its ability to increase levels of the neurotransmitter dopamine, which is associated with improved cognitive function.
- Supports Cardiovascular Health:
L-theanine may also help reduce levels of "bad" LDL cholesterol in the blood. In a study published in the Journal of Clinical Biochemistry and Nutrition, researchers found that supplementing with l-theanine for 12 weeks significantly decreased LDL cholesterol levels in overweight adults.
- Supports Immune System Function:
L-theanine has been shown to enhance immune system function by increasing levels of cytokines, which are proteins involved in the body's immune response.
- Lowers Blood pressure -
The nervous system gets activated by high levels of stress, leading to elevated blood pressure. L-theanine can inhibit the increase in blood pressure through its anti-stress effects on the autonomic nervous system.
Thus, L-theanine may be beneficial for those who experience a rise in blood pressure during stressful situations.
