    Cancer patients are increasingly targeted by unscrupulous individuals promoting dangerous pseudoscientific “treatments” – chief among them the consumption of extreme vitamin doses. While scientific evidence clearly establishes that vitamin D deficiency correlates with higher cancer rates, this correlation has been dangerously distorted into causation claims that massive vitamin doses can cure cancer.

    According to Euro News, a man who was taking vitamin D supplements far in excess of the daily requirements suffered serious health consequences for months. The middle-aged man was hospitalised in the UK after suffering from recurrent vomiting and other serious symptoms for three months.

    The article further stated, “Doctors are now warning the case was an example of hypervitaminosis D – the official term for a vitamin D overdose – a phenomenon that is on the rise due to the popularity of supplements. Hypervitaminosis D can cause a buildup of calcium in the blood, which can cause nausea and vomiting, weakness and frequent urination, according to the Mayo Clinic. The US medical centre also says vitamin D toxicity could cause bone pain and kidney problems, such as the formation of calcium stones.”

    This potentially deadly misinformation ignores a critical medical reality: megadosing vitamins doesn’t cure cancer and instead risks severe vitamin toxicity that can damage organs, disrupt treatment efficacy, and create devastating health complications when patients are already vulnerable.  When serious side effects arise, the individuals promoting it claim that it is a side-effect of either the illness or the medical drugs prescribed or the chemotherapy itself.  

    Vitamin Supplementation: Safety Guidelines and Boundaries

    Responsible vitamin supplementation serves an important role in health maintenance, particularly for individuals with specific needs based on age, genetics, medical conditions, or dietary limitations. However, the distinction between supplementation and megadosing represents the difference between medicine and potential poison.

    Recommended Daily Intake vs. Upper Tolerable Limits

    The chart below outlines both the recommended daily intake (RDI) and tolerable upper intake levels (UL) for essential vitamins – boundaries established through rigorous scientific research:

    VitaminVitamin AVitamin B1 (thiamine)Vitamin B2 (riboflavin)Vitamin B3 (niacin)Vitamin B5 (pantothenic acid)Vitamin B6 (pyridoxine)

    Vitamin B9 (folate)Vitamin B12 (cobalamin)Vitamin CVitamin DVitamin EVitamin K
    RDI for adult men RDI for adult women Upper Tolerable Limit (UL)
    900 mcg RAE 700 mcg RAE 3,000 mcg RAE
    1.2 mg 1.1 mg No UL established
    1.3 mg 1.1 mg No UL established
    16 mg NE 14 mg NE 35 mg
    5 mg 5 mg No UL established
    1.3 mg 1.3 mg 100 mg
    Vitamin B7 (biotin) 30 mcg 30 mcg No UL established
    400 mcg DFE 400 mcg DFE 1,000 mcg
    2.4 mcg 2.4 mcg No UL established
    90 mg 75 mg 2,000 mg
    600 IU 600 IU 4,000 IU
    15 mg 15 mg 1,000 mg
    120 mcg 90 mcg No UL established

    Exceeding these upper limits without medical supervision can trigger toxicity reactions ranging from uncomfortable to life-threatening. While healthcare providers may occasionally prescribe temporary high-dose treatments for specific deficiencies (such as vitamin D injections of 50,000 IU to correct severe deficiency), these are carefully monitored medical interventions—not self-administered regimens.

    The Stark Reality: Vitamin Overdose Consequences

    What cancer patients desperate for solutions aren’t told by supplement marketers is that vitamin megadosing can create severe health complications:

    • Fat-soluble vitamin overdoses (A, D, E, K) can cause organ damage as these compounds accumulate in body tissues
    • Water-soluble vitamin excesses (B complex, C) can overwhelm elimination systems and interfere with medication effectiveness
    • Extreme doses can create dangerous biochemical imbalances when the body’s regulatory systems become overwhelmed

    In the most severe cases, vitamin toxicity has led to nausea, vomiting, severe rashes, hospitalization and even death—an unconscionable outcome when patients were seeking healing.

    The Critical Takeaway

    While appropriate vitamin supplementation plays a valuable role in overall health maintenance, the promotion of megadoses as cancer treatments represents a dangerous exploitation of vulnerable patients. Cancer treatment decisions should always involve qualified medical professionals who can provide evidence-based guidance specific to individual circumstances.

    The most responsible approach to supplementation involves consultation with healthcare providers, adherence to established dosing guidelines, and recognition that more is not better when it comes to vitamin intake. True healing comes through integrated, evidence-based approaches—not dangerous shortcuts that risk making a difficult situation catastrophically worse.

    I have no idea what this guy took but I do know 600IU = 0.015Mg of D3 in the chart is an absolute joke. Many MDs I know recommend 2500IU/day (and double that in the winter) as a baseline and usually goes higher once they get the D3 levels tested which everyone should do when they go blood tested and retested if deficicient after a year of upping dosage.

    We have gone backwards instead of listening to modern medicine and our doctors we have allowed charlatans and fakers sell us useless st best and dangerous st most treatments. And we run to these phonies.
    In the sixties there was apricot treatments for cancer and it killed many. We haven’t learnt from experiences

    You do know what they tell you to take (chemo & radiation) causes 1000 times worse symptoms every single time… do research on healing the whole person instead of focusing on poisoning away some of the symptoms of the disease!!
