You're ingesting a credit card of plastic every week.

Microplastics are fragments smaller than 5mm. Nanoplastics are smaller still — small enough to cross the gut lining, enter the bloodstream, and lodge inside individual cells. Once inside, they trigger a cascade your body struggles to contain.

The core mechanism: microplastics generate reactive oxygen species (free radicals). Your cells respond with inflammation. Over time, that chronic oxidative burden compounds — accelerating cellular aging, disrupting hormone signaling, and taxing your liver's detox capacity.

Glutathione (GSH) is a tripeptide produced in every cell. It's the most abundant intracellular antioxidant in the human body — and the one your liver relies on most for phase II detoxification, the process of binding toxins and tagging them for excretion.

When your oxidative load exceeds your glutathione supply — which happens chronically under environmental toxin pressure — cells enter a state of sustained stress. Tissue repair slows. Inflammation signals don't resolve. Energy output drops.

Replenishing circulating glutathione is the most direct intervention for supporting your body's natural capacity to manage the load microplastics create.

Glutathione is fragile. When taken orally, stomach acid and digestive enzymes break it down before meaningful absorption occurs. Studies show oral supplementation raises plasma glutathione only marginally — and inconsistently.

Nasal delivery bypasses the GI tract entirely. The nasal mucosa is highly vascularized, absorbing compounds directly into systemic circulation within minutes. This is why Curetonix uses nasal spray as its delivery format — not because it's novel, but because the pharmacokinetics are superior.
