PheniTropic PM by Biotics Research contains a proprietary blend of neurotransmitter precursors, with the added benefit of vitamin B6.

  • Promotes proper neurotransmitter balance
  • Supports quality sleep
  • Boosts the relaxation response

Neurotransmitters are required for everything from signaling the heart and lungs to function, to enabling the body to sleep so regeneration and repair can occur. Unfortunately, neurotransmitter balance can be easily disrupted by a number of factors including genetics, immune function, diet, stress, and general chemical exposure. This imbalance can result in less-than-optimal neurotransmitter function, which can lead to anxiety, panic attacks, persistent worrying thoughts, inability to relax, mood disorders, and sleeplessness due to an “anxious mind” or inability to “switch off the mind.”


Phenibut, or beta-phenyl-gamma-aminobutryic acid, is a derivative of GABA. GABA is a primary inhibitory neurotransmitter, which means it inhibits excitatory neurotransmitters in the brain, and is used at the great majority of fast inhibitory synapses in virtually every part of the brain. A number of sedatives act by enhancing the effects of GABA. One of the “feel good” brain neurotransmitters, which include serotonin, dopamine and norepinephrine, GABA is commonly referred to as the “anti-anxiety neurotransmitter”.


Taurine, an amino acid, works to regulate water and mineral levels in the blood. A natural substance that can be found in animal meat, fish and milk products, taurine may stimulate GABA activity by activating GABA receptors. In one study, the relationship between GABA and taurine concentrations suggests that the presence of taurine helps activate GABAρ1 receptors. In addition, taurine has been found to produce an anxiolytic effect and may act as a modulator or anti-anxiety agent in the central nervous system by activating the glycine receptor.

Vitamin B6

Vitamin B6 acts as a cofactor in the conversion reaction of glutamate, a principal excitatory neurotransmitter to GABA, a principal inhibitory neurotransmitter. Inadequate levels of vitamin B6 may result in lower levels of GABA.

PheniTropic PM is free of common allergens. It does not contain corn, dairy, salt, soy, sugar, gluten or any artificial flavors or colorings.

I use nightly

Overall Rating

I use this product at the suggestion of my nutritionist. Some nights I sleep 7 - 8 hours and I am thankful. Other nights I awaken often. I am not sure why the inconsistency in these sleep patterns. I do know I tested NOT taking PheniTropic PM one night and awakened every 2 or so hours. So bottom line: I use nightly!

Excellent product

I love this product and never run out of it. This product has greatly improved my sleep, the depth of my sleep and the improved time it takes me to get to sleep.
