The Science

SeroTrex provided by NeuroScience Inc., chewable tablets with ingredients important for mood and reducing stress. The primary excitatory neurotransmitter in the brain. Glutamatergic signaling underlies mechanisms related to anxiousness and stress.



  • Glutamate
  • Serotonin

Glutamate, anxiousness, and stress 

Glutamate is associated with anxiousness and stress. 

  • Stress activates the hypothalamus-pituitary-adrenal (HPA) axis which releases glucocorticoids that affect brain function. 
  • Studies have shown that the brains of both pediatric and geriatric populations are particularly susceptible to stress. 

L-theanine acts as a glutamate receptor antagonist. 

  • L-theanine binds to glutamate receptors (AMPA, kainate, and NMDA receptors) and blocks the binding of glutamate to its receptors. 

L-theanine improves sleep efficiency 

The effects of L-theanine were assessed in randomized, double-blind, placebo-controlled studies. 

  • In individuals 8-12 years of age, L-theanine (200 mg) twice daily (morning and afternoon) significantly increased sleep efficiency (percentage of night spent sleeping restfully) and reduced nocturnal motor activity.
  • In adults, single administration of L-theanine (200 mg) significantly reduced feelings of stress under mental strain.


Amino Acid:

  • 5-HTP
  • L-theanine

    Though I don’t typically believe in 5 star ratings, these products certainly deserve at least 4.5 stars! I have personally used them for over 12 years and absolutely love them! HPA axis Neuro/Endo testing has become a mainstay in establishing baseline neurotransmitter and hormone values while enabling our health coaches to implement neurotransmitter modulation protocols for all of our clients. I highly recommend taking your health and wellness to the next level while incorporating testing into your program.
