For Sleep Improvement:
L-tyrosine is not commonly used for sleep improvement, but in some studies focusing on its effects on sleep quality in specific conditions, doses ranging from 100 mg to 2000 mg have been used.

For Physical Performance:

Please note that individual responses to L-tyrosine can vary, and the optimal dosage may depend on factors such as body weight, tolerance, and the specific purpose for which it is being used. It is essential to consult with a healthcare professional before starting any supplement regimen to determine the appropriate dosage and ensure it aligns with your individual health needs.
