3. 5-HTP increases REM sleep significantly (typically by about 25 percent) while simultaneously increasing deep sleep stages 3 and 4 without increasing total sleep time. 5- HTP accomplishes this by shortening the amount of time you spend in sleep stages 1 and 2, which in certain ways are the least important stages of the cycle. The higher the dose, the more time spent in REM. 4. By shifting the balance of the sleep cycle, 5-HTP makes sleep more restful and rejuvenating. Instead of waking feeling tired, worn out, and "hungover," people taking 5- HTP feel vibrant, well rested, and ready to take on the challenges of the day. When we sleep more deeply and dream more efficiently, we wake in the morning with our physical and psychological batteries fully charged. 5. The impact of 5-HTP on sleep stages is dose-related; taking higher doses produces a somewhat greater impact. In most cases, the lower dosage is adequate. Higher doses may lead to a greater number of disturbing dreams and nightmares due to abnormally prolonged REM sleep. It can also lead to mild nausea.
