What is in it, at what dose.

Two products, both disclosed in full. Glutathione supplementation is an area with genuine debate about oral absorption, and we would rather set that out than talk around it.

How the delivery system works

Oral glutathione has a genuine absorption problem: the molecule is a tripeptide and is substantially broken down in the gut before it reaches circulation. That is why the category is full of delivery technologies.

Diagram of a capsule cross-section showing glutathione held at the centre inside a CyLoc fibre matrix shell, with DexKey release trigger points on the outer surface.
Each glutathione molecule sits inside a CyLoc® matrix shell. DexKey® trigger points control where along the gut that shell opens.
  1. Encapsulation

    Each glutathione molecule is enclosed individually in a dextrin-fibre matrix — CyLoc® — rather than grouped inside a lipid bubble, which is how liposomal delivery works.

  2. Passage through the stomach

    The matrix shell is intended to hold together through stomach acid, which is where a meaningful share of unprotected glutathione is broken down before it can be absorbed.

  3. Targeted release

    DexKey® trigger points on the shell are designed to open at specific points along the intestine, rather than releasing unpredictably wherever the shell happens to break down.

  4. Absorption

    Glutathione released at the intended site is available for uptake, without requiring the fats or emulsifiers a liposomal formulation needs to hold its structure.

CyLoc® and DexKey® are registered trademarks of Tesseract Medical Research, used under licence. GlutaYouth™ is a distinct formulation.

Being straight about this

Delivery technology addresses a real limitation, and we think this one is a sound approach. But we are not going to tell you it is settled. Comparative human absorption data between delivery systems is limited, and anyone quoting you a precise multiple over liposomal is quoting a number that does not exist in the published literature.

Manufacturing and testing

GlutaYouth™ is manufactured by Factory6, Inc., in Lindon, Utah. This is what we can verify about that facility and about batch testing, stated plainly rather than as a row of badges.

WhatVerified detail
Facility certificationNSF/ANSI 455-2:2021, certificate C0849922-HSCDS-1, current through June 2026. This standard covers 21 CFR Part 111 dietary supplement current Good Manufacturing Practice.
FDA facility registrationRegistered as a food and dietary supplement facility, initial registration 10823662032.
Independent microbial testingA representative batch was tested by an accredited third-party laboratory for total aerobic microbial count, coliforms, E. coli, Salmonella, Staphylococcus aureus, and yeast and mould. Salmonella, E. coli and Staph aureus were not detected; coliforms and yeast/mould were below the lab's detection threshold. Aerobic count was reported at 700 cfu/g, a figure the manufacturer did not set a numeric limit against on this report.

What this testing does and does not cover

The microbial panel above verifies the batch was clean of the pathogens it screens for. It does not verify potency — it is not an assay confirming the 350 mg glutathione or 10 mg silver figures on the label. We have not seen an identity or potency assay for this product and are not representing that one exists.

On FDA registration: registering a facility is a regulatory requirement for anyone manufacturing food or supplements in the US. It is not an FDA approval and does not mean the FDA has evaluated this product. No supplement claims FDA approval, because none can.

A current Certificate of Analysis for a specific batch is available on request — support@rinnovarelabs.com.

Topical

Rinnovare Labs™ Rejuvenation Gel

$60.00. A topical gel for daily use on the face and neck.

The Rejuvenation Gel tube in use.

The gel is a cosmetic product. It is formulated to affect the appearance and feel of skin — texture, tone, hydration — and it is regulated on that basis. It is not a drug and we make no claim that it alters skin structure or treats a skin condition.

It is designed to sit alongside GlutaYouth™ rather than duplicate it: one works topically, the other is taken orally, and neither depends on the other.

Before you buy

Things worth knowing

GlutaYouth™ contains silver. Silver accumulates in the body over time and is not an essential nutrient. Follow the stated dose of one capsule daily, do not stack it with other silver-containing products, and speak to your physician before taking it if you are pregnant, nursing, taking medication, or managing a health condition.

Neither product is a substitute for medical care, and neither has been evaluated by the FDA. If something on this page reads like a treatment claim, it is not intended as one — write to us and we will fix the wording.
