Support for mood regulation + sleep
- 5-HTP increases serotonin levels in the brain
- Healthy sleeping patterns
- Oral doses are well absorbed into the blood stream
5-HTP (5-hydroxytryptophan) is produced in the body from the amino acid tryptophan and is involved in nervous system health.1 It is a precursor to serotonin, a neurotransmitter involved in mood regulation, sleeping patterns, appetite, sexuality, and emotional states such as anger and aggression.2,3 5-HTP increases serotonin levels in the brain, which can help promote a calm mood and healthy sleep patterns.4
Unlike tryptophan, 5-HTP can easily cross the blood-brain barrier, making it effective for increasing serotonin levels in the central nervous system. Oral doses of 5-HTP are well-absorbed into the blood stream because it is not affected by other amino acids in digestion and it does not need a specific transport molecule.5
Vitamin B6 works with 5-HTP to create serotonin.6 If you are taking a B vitamin supplement, such as our B-Complex, you may wish to take the two products at the same time to optimize effectiveness.
Other Ingredients:Rice flour and Cellulose (capsules).
CAUTION:If you are currently taking antidepressant medication please consult a physician prior to use. May cause drowsiness.
Dosage:Take one or more capsule(s) daily, preferably on an empty stomach. To aid in sleep, take at bedtime.
