There are some nootropics Antioxidant properties And can reduce damage to nerve cells within the brain attributable to the buildup of free radicals.

Another study Among those that took L-theanine with caffeine in doses just like those within the above study, several cognitive outcomes improved, including being less at risk of distraction.
Although pure L-theanine is Well toleratedThere are relatively few human trials to indicate that it really works or is protected over the long run. Larger and longer studies examining Maximum dose can also be needed.
3. Ashwagandha
