5 OH Tryptophan

5-HTP is 5-Hydroxy-Tryptophan, also known as Oxitriptan is the direct physiological precursor of Serotonin, an essential chemical agent of the brain. Sufficient evidence has been found that the low level of Serotonin contributes to different brain and psychic diseases, such as sleep problems, depression, anxiety, compulsive disorders (including eating disorders), restless leg syndrome, migraines, fibromyalgia, and low pain threshold.

5-HTP INSTEAD OF TRYPTOPHAN

5-HTP is more effective than Tryptophan because only 1% or less of dietary/supplementary Tryptophan ever enters the brain. The rest is used to make various body proteins, vitamin B-3; and some may be broken down through the kynurenine pathway, which would convert to hydroxykynurenine (3-OH-K), Xanthurenic acid (XA) and hydroxyanthranilic acid (3-OH-AA) for urinary excretion. These 3 metabolites are all known to cause liver damage and bladder cancer. Indeed, in comparison to Tryptophan, some studies of 5-HTP have shown better results because it directly increases brain serotonin without major side effects.

Directions: Take 1-3 capsules per day or as recommended by a health care professional. Pure 5 OH Tryptophan should be taken with vitamins and minerals.

Recent Development

  • 5HTP differs from Tryptophan in that it slightly increases the activity of an energizing neurotransmitter,NE and Seratonin.
  • 5HTP is essential because body cannot manufacture its own
