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


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 support is needed for the inhibitory neurotransmitter system, particularly GABA.* Research shows GABA controls excitability in the brain, making healthy GABA activity critical for calm, relaxation, mood and sleep.1 The ingredients in Lentra work together to support healthy GABA activity.*

The NeuroSupport Blend™ (NSB) enhances absorption.* Improved absorption allows for smaller doses and fewer capsules. 

Lentra contributes, along with Prolent or Tranquilent, to rebalancing and supporting the inhibitory system. Lentra may be recommended in combination with SomniTR or Tranquilent to promote sleep.

Lactium® Generally recognized as safe (GRAS) status from the Food and Drug Administration. It acts as a GABA-A receptor agonist.*2 Lactium has been shown to decrease stress-related symptoms in women3 and significantly improve sleep quality.*4

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.*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 glycine receptors, act as a GABA-A receptor agonistand increase GABA concentration.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 clinically proven to maximize nutrient absorption.

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.
