5-Hydroxytryptophan (5-HTP) (Serotonin Precursor)


What Redefined Vitamins says about 5-Hydroxytryptophan (5-HTP):

This popular supplement is used for anxiety, mood swings, and sleep disorders, especially for people who wake up in the middle of the night with racing thoughts. Some people have a really hard time making enough serotonin (a brain chemical that affects relaxation and sleep) from protein (especially if gut health isn’t up to par). 5 HTP is an essential precursor that provides an extra boost for serotonin production. It can help improve your body’s ability to make enough serotonin to keep you feeling calm, happy and sleepy. A general recommendation is 50-100mg at all meals and/or before bed, and if you don’t notice improvement after a few weeks, we recommend increasing it until you do.

Manufacturer's Description:

Mood Support

5-HTP is a natural supplement that supports healthy mood and well-being. The main ingredient – 5-hydroxytryptophan (5-HTP) – is extracted from the plant species Griffonia simplicifolia.

5-HTP is a primary metabolite of the amino acid L-tryptophan. Many people may know that the amino acid, L-tryptophan, can induce sleepiness if eaten in high quantities. 5-HTP, on the other hand, doesn’t necessarily make you drowsy, but instead works to calm your brain and support relaxation.

Since 5-HTP readily crosses the blood-brain barrier, it is effective for increasing serotonin levels in the brain. 5-HTP differs from L-tryptophan in that it doesn’t necessarily make you drowsy but instead works to calm your brain and help you relax while still being alert. That being said, 5-HTP may be useful for better sleep quality since some of it will be converted to melatonin. Below are some of the most relevant research-backed benefits derived from 5-HTP use:

  • Supports relaxation, calmness, and mood
  • Stimulates deeper sleep
  • May support weight loss (in higher doses)
  • Supports neural tissue
