Targeted Nutritional Therapy™


Chewable Inhibitory Support*

A unique, chewable, cherry and raspberry-flavored formula providing support for the inhibitory neurotransmitter system—both serotonergic and GABAergic neurotransmission.* May be used when calm or relaxation is needed in the short term as well as for rebalancing the inhibitory system over the long term.* Doses are appropriate for use in the pediatric population.  
Encapsulating The Art & Science of Functional NutritionTM

Formula Overview

Balance between inhibitory and excitatory neurotransmitters is vital to health and well-being. Inhibitory neurotransmitters such as serotonin and GABA control excitatory signals in the nervous system. That’s why supporting inhibitory neurotransmitters often results in an overall calming and relaxing effect. 

Tranquilent includes ingredients that support the action of inhibitory neurotransmitters.* 5-HTP supports serotonin synthesis.* Myo-inositol works to support serotonergic receptors.*1 Theanine, as Suntheanine®, supports both the release of GABA and its function.*2,3

The chewable format makes Tranquilent easy to use for children and easy to take on the go as neededIt may also be combined with Lentra, SomniTR, or Prolent™ for added inhibitory support.* 

Tranquilent may be used in Initial, Restoration and Maintenance phases along the path to wellness.

L-theanine as Suntheanine® (standardized to >99%): Shown to promote relaxation by multiple mechanisms including antagonizing glutamate receptors, increasing the release of GABA and decreasing norepinephrine levels in the brain*2,3

5-HTP:A naturally occurring amino acid and metabolite of Ltryptophan. 5-HTP is the direct precursor in the biosynthesis of serotonin.* Use of 5-HTP avoids the rate-limiting conversion of tryptophan to 5-HTP 

Myo-inositol (inositol) A precursor for the second messenger system (phosphatidyl-inositol) used by noradrenergic, cholinergic and serotonergic receptors.* Inositol regulates numerous cellular functions including membrane and receptor function*1
