India’s wellness market is flooded with glutathione supplements. Walk into any pharmacy, scroll through any health platform, and you’ll find dozens of options — tablets, capsules, sachets, drips — all promising brighter skin, stronger immunity, sharper thinking, and slower aging. Most of them don’t work the way they claim to. Some don’t work at all.
That isn’t an opinion. It’s a well-documented scientific problem that took the world’s researchers decades to solve. And it has now been solved — in a product called Continual G, powered by a patented ingredient called Glyteine, available exclusively in India through SkinBB.
To understand why this matters, you first need to understand what glutathione actually is, why the body needs it, and why virtually every attempt to supplement it orally has failed — until now.
Your body produces glutathione naturally in every single cell. It’s a tripeptide — a short chain of three amino acids: glutamate, cysteine, and glycine — and it is the most abundant low-molecular-weight antioxidant in the human body. Scientists call it the “master antioxidant” because it doesn’t just neutralise free radicals by itself; it also regenerates other antioxidants like vitamins C and E, and plays a central role in detoxification, immune function, and cellular repair.
The problem is that glutathione levels naturally decline with age, illness, stress, environmental pollution, and chronic inflammation. When levels drop, cells become vulnerable to oxidative damage — the slow, cumulative process at the root of premature aging, dull and uneven skin, sluggish immunity, brain fog, and a growing list of chronic conditions. Research links depleted cellular glutathione to everything from Alzheimer’s disease and Parkinson’s to diabetes, heart failure, and impaired recovery from physical exertion.
“Glutathione is the body’s most important antioxidant — and it is the one supplement that has eluded science for nearly a century. Until now.”
Given all of this, it seems obvious that supplementing glutathione should be a major priority. Researchers have thought so for decades. The challenge has been that knowing glutathione matters and being able to deliver it effectively are two very different things.
Here is the core issue with every standard glutathione supplement on the market: glutathione is a tripeptide, which means it is a protein fragment. When you swallow a protein, your digestive system is designed to break it apart. That is, quite literally, what digestion does.
Liposomal glutathione, S-acetyl glutathione, sublingual forms — all represent attempts to work around this fundamental barrier. Some improve absorption marginally. None have been shown in peer-reviewed, published human clinical trials to meaningfully raise glutathione levels inside cells following a single dose. The industry has been selling the idea of glutathione supplementation without being able to deliver it.
In 1997, Dr Wallace Bridge — then working for one of the world’s leading baker’s yeast manufacturers and later Associate Professor at the University of New South Wales in Australia — began studying glutathione from an industrial manufacturing perspective.
What he noticed, and what no researcher before him had recognised and pursued with rigour, was the behaviour of a naturally occurring compound called gamma-glutamylcysteine — GGC for short. GGC is the immediate precursor to glutathione in the body’s own two-step synthesis process. The first enzyme joins glutamate and cysteine to make GGC. The second enzyme adds glycine to GGC to produce glutathione.
Bridge’s insight was this: if GGC could be made available as a supplement, the body wouldn’t need to absorb intact glutathione at all. Instead, cells would receive the direct building block they need, synthesise the glutathione themselves, and raise their own levels — bypassing every barrier that defeats traditional supplementation entirely.
The problem was that GGC wasn’t commercially available. So Bridge and his PhD student Martin Zarka spent years inventing a process to manufacture it. That manufacturing process — and the resulting patented ingredient, now branded as Glyteine — is the foundation of Continual G.
This is a fundamentally different mechanism from every other approach to glutathione supplementation. Other products try to deliver glutathione from outside. Continual G delivers the raw material your cells need to make it themselves — from within.
“No other compound, including glutathione itself and the cysteine prodrug N-acetylcysteine, has been shown to be able to rapidly increase cellular glutathione levels following a single dose. Keep in mind, it is inside cells, not outside, where glutathione is most needed.” — Dr Wallace Bridge
This is not theoretical. Glyteine is the only ingredient proven in a peer-reviewed, published human clinical trial to raise cellular glutathione following a single oral dose. The landmark study, authored by Martin Zarka and Dr Wallace Bridge and published in the journal Redox Biology in 2017, measured glutathione levels inside lymphocytes — white blood cells — of healthy participants before and after single doses of GGC.

Glutathione levels peak — above homeostasis Cellular glutathione reaches maximum concentration — measurably above the body’s normal resting levels. This ‘above homeostasis’ result defines Glyteine’s clinical uniqueness. |

Levels return to baseline Glutathione naturally returns to basal levels, consistent with the body’s tightly regulated antioxidant system. Daily supplementation maintains ongoing elevation. |
The trial was sponsored by the University of New South Wales, registered with the Australian New Zealand Clinical Trials Registry, and cleared by the UNSW Human Research Ethics Committee. These are not marketing studies. They are independently reviewed science, published in a peer-reviewed journal.
Glyteine has also been designated Generally Recognized as Safe (GRAS) through the US FDA’s self-affirmation process — following in-vitro, preclinical, and human studies assessing its safety and efficacy profile.
India is the world’s most glutathione-obsessed skincare market. From skin-brightening injectables to daily oral supplements, demand for glutathione products has exploded over the last decade — driven by a cultural desire for luminous, even-toned skin and a growing awareness of antioxidant health. The irony is that most of what the Indian market has been consuming doesn’t deliver what it promises, for the exact reasons described above.

WHAT SKINBB’S INDIA EXCLUSIVE MEANS FOR YOU Continual G with Glyteine is the only clinically proven, single-dose glutathione supplement in the world. It is now available exclusively in India through SkinBB — meaning no other platform, retailer, or distributor in India carries it. This is not SkinBB adding another product to a catalogue. It is SkinBB applying its See Beyond curation standard to one of the most scientifically significant nutritional launches of the last two decades — ensuring Indian consumers get access to the real thing, not an imitation. |
What makes this partnership consistent with SkinBB’s See Beyond philosophy is simple: Continual G doesn’t borrow authority. It earned it — through 20 years of research, a patented manufacturing process, peer-reviewed publication, GRAS designation, and a mechanism of action that addresses the fundamental failure point of every competitor in the category.
WHY CONTINUAL G MEETS SKINBB’S CURATION STANDARD
1. Why don’t regular glutathione supplements work?
Standard oral glutathione is broken down by stomach acid and digestive enzymes before it can be absorbed. Even if fragments enter the bloodstream, glutathione cannot cross cell membranes intact — and it is inside cells where it is needed. Published research confirms oral bioavailability is below 1%.
2. What is Glyteine and how is it different?
Glyteine is a patented form of gamma-glutamylcysteine (GGC) — the body’s own immediate precursor to glutathione. As a dipeptide rather than a tripeptide, it survives digestion, enters cells directly, and triggers the cell’s own glutathione synthesis from within. It bypasses every barrier that defeats conventional glutathione supplements.
3. Has Continual G been clinically tested?
Yes. A peer-reviewed human clinical trial published in Redox Biology (2017) by Zarka and Bridge demonstrated that a single oral dose of GGC raised intracellular glutathione levels above homeostasis within 90 minutes, peaking at 2–3 hours. It is the only supplement to have achieved this result in published clinical research.
4. Who developed Continual G?
Continual G was developed by INID Research Lab, founded on the research of Dr Wallace Bridge, Associate Professor at the University of New South Wales in Australia. Dr Bridge began his glutathione research in 1997 and spent over 20 years developing the manufacturing process for Glyteine alongside his PhD student Martin Zarka and engineering partners.
5. Where can I buy Continual G in India?
Continual G is available exclusively in India through SkinBB. No other Indian platform, pharmacy, or retailer carries it.
6. Is Continual G safe?
Glyteine has received GRAS (Generally Recognized as Safe) designation through the US FDA’s self-affirmation process, following extensive in-vitro, preclinical, and human safety studies. GGC is a naturally occurring compound produced in every cell in the human body.
