A bottle of Lentra- a neurotransmitter supplement
Targeted Nutritional support™


GABA Receptor Formula*

Lentra™ is a natural formula targeting GABA-A receptors.* It is a highly effective product which supports inhibitory neurotransmission and allows relaxation and restfulness without inducing sedation.*

Encapsulating the Art & Science of Functional nutrition™

Formula Overview

Use when seeking support for healthy inhibitory neurotransmitter function, particularly GABA.* Data shows GABA controls excitability in the brain, making healthy GABA activity critical for balanced calm, relaxation, healthy mood and sleep.1 The ingredients in Lentra are designed to work together to support healthy GABA activity.*

The NeuroSupport Blend™ (NSB) is designed to enhance absorption.* 

Lactium® It acts as a GABA-A receptor agonist to maintain healthy receptor activity.*2 Lactium has been shown to decrease stress-related symptoms for balance in women3 and significantly improve healthy sleep quality.*4

L-theanine as Suntheanine® (standardized to >99%) L-Theanine intake is shown to restore balanced relaxation by balancing multiple internal mechanisms, leading to increased healthy GABA activity and decreased norepinephrine activity.*5,6

Taurine (as taurate free base) Source of taurine, an amino acid molecularly bound to magnesium. Taurine is an inhibitory neuromodulator that can activate healthy glycine receptors, and act as a GABA-A receptor agonist while increasing GABA activity to restore balance.7

Magnesium (as magnesium bisglycinate) Bioavailable form of magnesium as well as a source of glycine, an inhibitory neurotransmitter. 

NeuroSupport Blend (NSB)Proprietary mixture composed of Bioperine® and plant-based enzymes designed to maximize nutrient absorption.

Featured Ingredients


L-theanine (as Suntheanine®)

Amino Acid

Shown to promote relaxation by multiple mechanisms including antagonizing glutamate receptors, increasing the release of GABA, and decreasing norepinephrine levels in the brain.*



Amino Acid

Taurine is an inhibitory neuromodulator that can activate glycine receptors, act GABA-A receptor agonistand increase GABA concentration.*

Lactium Logo


Bioactive Peptide

Lactium has been shown to decrease stress-related symptoms in women and significantly improve sleep quality.* 


What They're Saying

I hear stories in my office every day, but it’s not just about this product but the combination. With Sanesco’s products, people will say, “I can't believe how good I feel.

Sharon Norling, MD, MBA

What I noticed right away about the formulas was that they had the NSB™ (NeuroSupport Blend) in them. So many of our patients with adrenal issues also have gut issues, and they’re malabsorbing. Getting them on a product that's going to actually be bioavailable was super important.
