The Science Behind GlutaYouth™

Most supplements haven’t changed in decades. GlutaYouth™ pairs 350 mg of reduced glutathione with patented CyLoc® & DexKey® delivery — engineered so more of what you take actually arrives. This page shows the research, the mechanism, and every ingredient in the capsule. No hype.

Why Glutathione Matters

The master antioxidant your body already makes.

Glutathione is a tripeptide — built from cysteine, glycine and glutamic acid — that sits at the center of your antioxidant defense. It neutralizes free radicals, supports detoxification, and recycles vitamins C and E. Research on oral glutathione at 250–500 mg/day links it to higher blood levels, lower oxidative stress and measurable skin benefits.

What the Research Says

Evidence, not anecdotes.

Three findings from the published literature on oral glutathione — with links to the sources, so you can read them yourself.

Skin & Appearance

Measurably clearer-looking skin

Randomized trials report improvements in melanin index, wrinkle reduction and elasticity for oral glutathione after 12 weeks of daily use.

Oxidative Stress

Higher blood glutathione, less oxidative load

Daily oral glutathione raised blood glutathione levels and reduced biomarkers of oxidative stress in clinical studies at 250–500 mg/day.

Immunity & Detox

Central to immune cell function

Glutathione is critical for immune cell function and liver detoxification pathways.

Our Standard

Smarter, cleaner, gentler.

GlutaYouth™ isn’t about cramming as much as possible into a pill. It’s about giving your body what it can actually use — advanced science, clean ingredients, and a design philosophy rooted in real research. No hype. No shortcuts. No empty promises.

The Delivery Technology

One molecule. One cage. One key.

Traditional capsules and even liposomal fat-bubbles can break down before your body can use them. GlutaYouth™ takes a different route.

CyLoc® encases each glutathione molecule in a dextrin-fibre cage; DexKey® trigger points open it where intestinal absorption peaks.
Step 1 · Protection

CyLoc® locks each molecule

Every glutathione molecule is sealed inside its own dextrin-fiber cage — an octadextrin matrix engineered to survive stomach acid intact.

Step 2 · Release

DexKey® opens it at the right place

Trigger points in the cage respond in the intestine — releasing glutathione exactly where absorption peaks, instead of leaking it in the stomach.

Step 3 · Result

More of what you take, actually arriving

Better bioavailability from a 350 mg dose — no fats, no emulsifiers, no mega-dosing. Clean dextrin fiber, gentle on digestion.

Questions, answered honestly

Formula & safety

What’s inside each GlutaYouth™ capsule?

350 mg reduced glutathione (CyLoc® protected), 10 mg nano colloidal silver complex, and vegan capsules — no fillers, no animal products.

Why Nano Silver?

Silver has a long history of use. In GlutaYouth™, the nano silver complex serves as a stable, carefully measured (10 mg) carrier that pairs with glutathione as part of our proprietary CyLoc® formula. We make no medical claims about it.

What makes GlutaYouth™ different?

Most glutathione supplements rely on liposomal delivery — fragile fat bubbles that can break down before reaching the intestines. GlutaYouth™ uses patented CyLoc® & DexKey® delivery instead: each glutathione molecule is locked in a natural dextrin-fiber cage that survives stomach acid and releases at the optimal point of absorption. No fats, emulsifiers or fillers — just clean, targeted delivery.

Why does absorption matter so much?

Oral glutathione is a tripeptide — much of it is broken down in the gut before absorption. CyLoc® and DexKey® are designed to shield it through the stomach and release it where uptake happens. Comparative human data between delivery systems is still limited, which is why we describe it honestly rather than overpromise.

Is GlutaYouth™ FDA approved?

No dietary supplements in the U.S. are FDA “approved.” GlutaYouth™ is produced in FDA-registered, GMP-certified facilities and tested for safety and quality.

Is it safe to take colloidal silver?

GlutaYouth™ uses a low dose (10 mg) of nano silver as a carrier, not as a standalone supplement. Long-term, high-dose silver intake can cause side effects. Always follow label directions and consult your healthcare provider.

How do I use GlutaYouth™?

One capsule daily with water — 60 capsules is a full two-month supply. Consistency matters more than timing.
