Product Description:

Tyro-HTP Plusis a proprietary blend exclusive to Bevko Vitamins that is made up of precursor amino acids, building blocks that are required to make certain substances in the body. The body uses these amino acids and turns them into important neurotransmitters like dopamine and serotonin, which are essential for regulating things like mood, attention, and mental alertness.

Suggested Use: As a dietary supplement, take one (1) or two (2) tablets per day or as recommended by your physician or health care professional.

Caution: If pregnant or lactating, use only as directed by your physician.


  • If you are taking phenylalanine or a product containing phenylalanine, you should avoid Nutrasweet (aspartame) and other foods that contain aspartame.
  • Do Not use this product if you are taking antidepressant medications unless specifically directed to do so by your physician.

Importance of Neurotransmitters

Neurotransmitters are chemicals that transmit information (in the form of electrical signals) from one part of the body to another. This transmitted information affects mood, behavior, motivation, energy, attention, and mental alertness. While these transmitters are found in different parts of the body, many of them are concentrated in the brain.

If people suffer from a lack of these mood-regulating neurotransmitters, they may feel depressed, anxious, lethargic, and unable to think clearly. Many may turn to anti-depressants that increase the amount of available neurotransmitters, but Bevko Vitamins' Tyro-HTP Plus provides the natural, biological ingredients necessary to maximize neurotransmitter levels and improve mood and cognition as a result

Components in Tyro-HTP Plus

Tyro-HTP Plus contains 4 precursor amino acids: 5-HTP, L-tyrosine, phenylalanine, and glutamine.


The amino acid 5-HTP is the direct precursor for the neurotransmitter serotonin, which helps regulate:

  • mood
  • sleep
  • sexuality
  • appetite

Deficiencies of serotonin are thought to contribute to a number of disorders, including:

  • depression
  • migraines
  • anxiety
  • insomnia
  • nausea
  • bipolar disorder
  • memory issues


L-Tyrosine is a precursor for dopamine, a neurotransmitter that releases feelings of pleasure that reinforce or motivate a person toward certain activities. For this reason, dopamine is called the "reward" chemical. It also:

  • helps the brain control motor skills
  • releases feelings of pleasure that reinforce or motivate a person toward certain activities. For this reason, dopamine is called the reward chemical.
  • increases resistance to stress
  • acts as one of the body’s natural pain relievers
  • decreases symptoms of depression, anxiety, and addiction withdrawal

Deficiencies of dopamine typically show up first as loss of energy and mental sluggishness. Later deficiencies can manifest in many ways, including:

  • tremors
  • Parkinson’s disease
  • joint pain
  • movement disorders
  • thyroid disorders
  • nicotine/sugar/junk food cravings
  • substance abuse
  • slow metabolism
  • mood swings as well as other personality issues
  • memory and attention issues

Too much dopamine, on the other hand, can over-stimulate a person so that they become intense, obsessed, and impulsive.


Phenylalanine (PEA) is converted in the body to the dopamine precursor, L-tyrosine, and it also builds norepinephrine (noradrenaline).
Norepinephrine acts as an:

  • internal stimulant to increase energy levels
  • anti-depressive substance in humans

PEA is found in high concentrations in chocolate. Low levels of PEA are typically found in people with depression as well as in schizophrenic patients.


Glutamine (known as brain food) is the most common amino acid in the body, and it is the primary provider of nitrogen for the body. It is also a precursor to the powerful neurotransmitter GABA (gamma-aminobutyric acid), which:

  • aids in proper brain function, memory, and mental alertness
  • serves as a relaxant in the body

Deficiencies of GABA can lead to a number of problems, including 

  • panic attacks
  • depression and mood disorders
  • obsessive-compulsive disorder and phobias
  • cardiac arrythmias
  • tremors
  • dizziness
  • headache
  • hyperventilation
  • insomnia
  • irritable bowel syndrome
  • PMS
  • stroke
  • tinnitus

Bevko Vitamins' Tyro-HTP Plus is made up of amino acids that build crucial neurotransmitters for regulating mood and many other functions/feelings. If you're experiencing any of the above symptoms, consider supplementing with Tyro-HTP Plus today!
