The manufacturing process should give anyone pause. This isn't sunshine captured in a bottle. It's sheep's wool grease (lanolin) irradiated with UV light, then extracted using chloroform – a known carcinogen that the safety sheets warn "may damage the unborn child." Industrial chemistry masquerading as a vitamin. Whatever your body produces when sunlight hits your skin, this isn't it. --UNBEKOMING
I have never taken a vitamin D supplement. Looks as if this might have been a wise choice.

Then there's the mechanism of death – identical in rats and humans. Cholecalciferol kills through hypercalcemia: calcium floods the bloodstream, calcifies soft tissues, damages kidneys, causes heart failure. When rats eat those poison pellets, this is how they die. When humans overdose on vitamin D, this is exactly what happens to them. Same molecule, same biological pathway, same organ damage. The only difference is the dose and the timeline.
The mechanism gets worse when you understand the magnesium connection. Excess vitamin D doesn't just flood your body with calcium -- it actively depletes magnesium in the process. The hormone form of D signals your intestines to preferentially absorb calcium over magnesium. Your kidneys need magnesium to dump the excess calcium, but the very substance causing the calcium overload is simultaneously blocking your ability to get the magnesium needed to fix it.
It's a biochemical trap: the more vitamin D you take to "fix" your deficiency, the more you deplete the magnesium that would protect you from its toxicity. Magnesium is anti-inflammatory; calcium is inflammatory. We're systematically tilting everyone's mineral balance toward inflammation while calling it preventive healthcare. Some practitioners have observed this and recommend topical magnesium to bypass the compromised intestinal absorption -- essentially admitting that oral vitamin D supplementation breaks normal mineral metabolism so badly that you need to absorb minerals through your skin to compensate.
The question isn't whether vitamin D3 can be toxic. It clearly can. The question is whether taking it at supplement doses is slowly building toward that same toxicity, just stretched over decades instead of days.
Where Agent131711's argument becomes more debatable is the dismissal of dose-response. "Poison is poison," they say, but this oversimplifies how biology works. The difference between rat poison concentration (0.075%) and typical supplement doses is often 1000-fold or more. Pharmacology exists as a discipline because dose-response relationships are real and measurable.
It's worth noting that vitamin D toxicity from supplementation at recommended doses is genuinely rare. The Endocrine Society reports that toxicity typically requires doses above 10,000 IU daily for months. Millions supplement daily without acute poisoning. The question isn't whether massive overdoses are dangerous - they clearly are. The question is whether decades of daily supplementation at "normal" doses leads to subtle, cumulative harm that we're not adequately tracking.
We need to distinguish between acute toxicity (rare) and potential long-term effects (unstudied).
The mixture gets heated to 248°F, creating what the patent documents charmingly call a "soup" -- melted lanolin swimming in industrial chemicals. To speed dissolution, they add methanol and benzene. Benzene, for context, is what causes leukemia in factory workers. It's so toxic that OSHA strictly regulates workplace exposure, yet it's a standard ingredient in vitamin D production.
Next comes "purification" through a Diels-Alder cycloaddition, followed by irradiation in what's essentially an industrial X-ray machine. The base for this irradiation can be aluminum oxide (linked to Alzheimer's) mixed with more benzene. The irradiation supposedly "activates" the vitamin -- though what it's really doing is bombarding sheep grease with radiation after it's been dissolved in carcinogens.
The factories producing this are primarily in China and India, where environmental regulations are suggestions rather than rules. The powder ships worldwide in industrial drums, the same shipping infrastructure that moves industrial chemicals, because that's what this is -- an industrial chemical with a marketing department.
Now, defenders of supplementation will argue that many life-saving medications use similar industrial processes. Insulin involves genetically modified E. coli. Antibiotics require complex fermentation. Even "natural" supplements undergo extensive processing. They'll say the manufacturing process is a red herring – what matters is the final molecule, not how it's made.
This would be a fair point if we were talking about acute, life-saving medications given to sick people under medical supervision. But we're not. We're talking about something added to the milk supply, mandated in infant formula, recommended for daily consumption by healthy people for their entire lives. The standards should be different. When you're mass-medicating entire populations, the origin and purity matter enormously.
Moreover, the manufacturing process reveals something crucial: this isn't a nutrient we're extracting from food. It's an industrial chemical we're creating through industrial processes, then retroactively calling it identical to what our bodies produce. Would we accept this logic for other hormones? If we synthesized testosterone from coal tar and chloroform, would we add it to the milk supply and call it essential nutrition?
This is what we're being told to give our infants. This is what's mandated in milk. This is what your doctor measures in your blood and declares you deficient without. Not sunshine captured in a bottle, but sheep's wool dissolved in chloroform, irradiated like nuclear waste, crystallized through benzene, and packaged as health.
WHAT ABOUT THE BENEFITS OF VITAMIN D3 SUPPLEMNTATION ON CANCER?
The cancer mortality data is equally puzzling. A meta-analysis of randomized controlled trials found approximately 15% lower cancer mortality with vitamin D supplementation. Not cancer incidence – people still got cancer at the same rates – but fewer died from it. The reduction was consistent across different types of cancer. If cholecalciferol is purely toxic, why would poisoning people slightly improve their survival from an entirely different disease process?
In intensive care units, a meta-analysis of 16 trials involving 2,449 critically ill patients showed a mortality risk ratio of 0.78 with vitamin D supplementation. Shorter ICU stays, less time on ventilators. These are people whose bodies are already under extreme stress, yet adding a known toxin apparently helps them recover faster.
WHAT ABOUT DIABETES?
Then there's the prediabetes data. Individual trials showed borderline or no effect, but pooled analysis across eight trials found an 11% reduction in progression to diabetes. Modest, but measurable. More interesting: the effect was stronger in non-obese participants. Why would body composition affect how a poison influences blood sugar regulation?
