Natrol 5-HTP Time Release 100mg

5-HTP is an amino acid that acts as a precursor to serotonin, a neurotransmitter that regulates appetite, mood, feelings, behaviour, and sleep. The body produces 5-HTP from the amino acid tryptophan, whereas 5-HTP supplements are produced from the seeds of Griffonia simplicifolia plant. Natrol 5-HTP helps regulate healthy mood, promote relaxation and sleep, and achieve healthy appetite control.

  • 5-HTP naturally promotes healthy mood, calmness, and relaxation. These psychoactive benefits of 5-HTP is due to its action on supporting healthy serotonin production in the brain. Mood disorders such as depression and anxiety have been directly linked with serotonin deficiency. 5-HTP supplements are suggested to provide healthy mood support to gain emotional and mental health.
  • 5-HTP supplements help individuals achieve healthy appetite control. Serotonin also influences appetite and low levels of this neurotransmitter increases food cravings and binge eating. Healthy appetite control can help people with obesity and people who are dieting to achieve more effective weight loss results.
  • Natrol 5-HTP can help in getting healthy sleep periods. 5-HTP influences not just serotonin but also melatonin, the hormone that regulates the body’s circadian rhythm or clock. It tells the body that it’s time for sleeping and rest.
  • 5-HTP together with DHEA and phenylalanine can support normal energy production. Energy levels decrease with age due to decrease production of these energy producing substances. Replenishing with 5-HTP supplements can help restore normal energy levels even during old age.
  • Higher 5-HTP levels support the body’s natural response to stress. This tryptophan derivative encourages relaxation and calmness during stressful situations.

5-HTP or 5-hydroxy-tryptophan is produced in the body from tryptophan, an essential amino acid required in the synthesis of serotonin. Serotonin is a neurotransmitter that influences mood, behavior, sleep, appetite control, perception of pain and discomfort, and relaxation. Reduced serotonin production occurs with age, and the imbalance is further aggravated with stress. Clinical research have linked serotonin imbalance with anxiety, depression, and insomnia. Tryptophan supplements were traditionally used to correct serotonin deficiency, especially those with resulting depression and anxiety disorders. It was only until 1989 when 5-HTP was discovered to be better than tryptophan as it is one step closer in the metabolic pathway to being converted to serotonin. Thus, 5-HTP may even be more effective in replenishing healthy serotonin levels in the brain. The benefits of 5-HTP is enhanced with adequate levels of Vitamin B6, Vitamin C, folate, and magnesium in the body. Natrol 5-HTP TR – Time Release is especially formulated a controlled delivery system that releases 5-HTP gradually and steadily for a period of time to optimise results.
