What is 5-HTP?

5-HTP, or 5-Hydroxtryptophan, is a derivative of the amino acid L-tryptophan. This nutrient is classed as an essential amino acid as it must be obtained through dietary means due to the body’s inability to produce it. Although this amino acid is present in foods such as cheese, fish and red meat, more and more people are choosing a high-quality supplement to increase their intake.

5-HTP is a supplement that has been subject to numerous scientific trials which have investigated its interaction with certain neurotransmitters.  Neurotransmitters such as serotonin and melatonin are chemical messengers that occur in the brain and are thought to influence the normal functioning of our bodies.

You may find that you live your life at a demanding and challenging pace, which can take its toll on your body. As a result of theses 5-HTP tablets may be a good choice to help support an active and busy lifestyle.
