L-Theanine: one of the main psychoactive compounds found in tea.

L-theanine is extremely safe and has been shown to mitigate the negative aspects of caffeine, such as anxiety, increased blood pressure and diminished sleep quality, while possibly improving upon the positive aspects. Its ability to enhance attention has been repeatedly verified. A recent systematic review of the effects of l-theanine and caffeine has confirmed that the combination seems to improve aspects of attention. The combination of L-theanine and caffeine may improve attention more than caffeine alone. L-theanine alone has been shown to boost alpha brain waves, a pattern of brain activity correlated with relaxed attention. In one recent animal study l-theanine consumption was associated with about a 25% increase in BDNF and about a 100% increase in NGF in the hippocampus. L-theanine taken with caffeine is one of the most reliable and safe nootropic stacks for improving focus.

L-theanine is an amino acid that is commonly found in tea leaves, particularly in green tea. It is believed to have several potential health benefits. Here are five potential benefits of taking L-theanine:

  1. Stress reduction: L-theanine is believed to promote relaxation by increasing the level of the neurotransmitters GABA, dopamine, and serotonin in the brain. This may help to reduce feelings of stress and anxiety.
  2. Improved sleep: L-theanine may help to improve sleep quality by promoting relaxation and reducing stress and anxiety.
  3. Improved cognitive function: Some studies suggest that L-theanine may improve attention, focus, and cognitive function, particularly when taken in combination with caffeine.
  4. Improved cardiovascular health: L-theanine may help to lower blood pressure and improve cholesterol levels, which may help to promote cardiovascular health.
  5. Antioxidant properties: L-theanine is also an antioxidant, which means it helps to protect cells from damage caused by free radicals.

It’s important to note that while L-theanine is considered safe for most people and generally well-tolerated, it’s always best to consult with a healthcare professional before starting any supplement regimen. Also, more research is needed to fully understand the potential benefits and risks of taking L-theanine.
