MetforminMar 15, 2026
Roughly 1 in 5 metformin products tested in large international surveys contained a probable carcinogen above safety limits. That sounds alarming, and it should be taken seriously. But here's the tension: the other 80% of tested batches met quality and safety standards, no adverse events have been definitively linked to the contaminated products, and abruptly stopping metformin creates its own set of risks for people managing diabetes. The real question isn't whether the recalls were justified (they were), but what you should actually do about it.
Between 2020 and 2022, over 281 extended-release metformin products were recalled in the US alone. The contaminant at the center of all of this is NDMA (N-nitrosodimethylamine), a substance classified as a probable carcinogen. Regulators worldwide set a strict daily limit of 96 nanograms, and a meaningful minority of products exceeded it.

Sodium thiosulfate has been saving lives in emergency rooms since 1912, and it still sits on the WHO's list of essential medicines. But the most interesting story isn't the one everyone already knows. Researchers are now finding that this simple sulfur compound does far more than neutralize poisons: it scavenges damaging free radicals, protects mitochondria, tames inflammation, and behaves like a signaling molecule tied to hydrogen sulfide, one of the body's own gaseous messengers.
The catch? Most of those newer roles have only been demonstrated in animal models and lab studies. What sodium thiosulfate (STS) can reliably do in humans right now, and what it might do in the future, are two very different conversations. Both are worth having.

Nanoparticles are being engineered to fight thyroid cancer and simultaneously accumulating in thyroid tissue where they disrupt hormones. This isn't a conflict between two separate fields. It's the same class of materials producing both results depending on context, dose, and design.
The important caveat up front: nearly all of this evidence comes from animal models, cell studies, or early preclinical work. No nanoparticle-based thyroid cancer therapy is in routine human use yet. But the dual nature of NP thyroid interactions, therapeutic potential on one side, endocrine disruption on the other, is worth understanding if you follow thyroid health or cancer research.

Mercury is a toxic metal that can affect the brain, kidneys, and nervous system, and testing is important if you've had possible exposure through fish, workplace contact, or accidental spills. The right test depends on the type and timing of exposure.

PFAS, often called “forever chemicals,” are synthetic compounds that resist breaking down in the environment and the human body. They are widespread in water, food, and consumer products, and research links them to cholesterol changes, immune dysfunction, hormonal disruption, and certain cancers. Here’s what you need to know about exposure, risks, and whether testing makes sense for you.

As vaping becomes increasingly popular, particularly among younger populations, a pervasive myth continues to spread: the belief that there isn't enough evidence to confirm vaping's harm. But nothing could be further from the truth. Extensive research paints a very different picture, highlighting significant health risks associated with vaping.
