• Your cells cannibalize their own mitochondria — Dinkov described this change as your cells dismantling their mitochondria. Once those engines are taken apart, the cells start depending on a faster but dirtier process that leaves behind waste like lactic acid. This is what keeps the cancer state alive. The more your cells rely on this shortcut, the more likely they are to keep breaking down instead of functioning normally.

• Many cancer cells are not beyond saving — If you improve the cellular environment, your cells often return to normal energy production. This means that cancer, at least in its earlier stages, doesn’t always need to be attacked or destroyed. Instead, giving the cells what they need to repair themselves can turn them back into healthy, functioning tissue:

[…]

• What to do for cells that are too far gone — Dinkov said they should be guided toward a natural shutdown process called apoptosis. This is a built-in safety feature in your body that removes damaged cells. “If it’s severely damaged and the cell can and should be forced to commit apoptosis, which is the controlled self-destruction,” he says.

• When your cells begin depending mostly on glycolysis, trouble starts — Dinkov explained that glycolysis doesn’t just mean less energy — it also changes the chemistry inside the cell. The buildup of lactic acid pushes your cells into a more reductive state, which signals them to break down their mitochondria even further. The result is a downward spiral where the cells lose their ability to return to normal function.

• The breakdown in energy production is central to cancer behavior — According to Dinkov, glycolysis is meant as a backup for short-term survival, but cancer locks cells into that mode permanently. If the mitochondria are not working properly, cells become aggressive, multiplying rapidly.

• Restoring oxidative phosphorylation is the key to turning the tide — If you can push energy production back into the mitochondria, your cells have a chance to function normally again. But if the mitochondria are too badly damaged, then the better option is for those cells to self-destruct through apoptosis. Either way, focusing on mitochondrial health rather than simply blasting cells with drugs or radiation offers a different healing pathway.

• Other hormones balance your system — Progesterone, pregnenolone, testosterone, and dihydrotestosterone (DHT) provide a beneficial effect. Dinkov explained that these hormones help your cells resist estrogen’s effects by keeping energy flowing through the mitochondria.

• Here’s one example of how hormones protect against cancer — According to Dinkov, progesterone directly blocks estrogen’s activity at the cell level:

“So, first of all, pregnenolone, progesterone, to a smaller degree, DHEA [Dehydroepiandrosterone], testosterone dehydrogenase — they’re all aromatase inhibitors. So, they directly limit the synthesis of new estrogen no matter where it has been synthesized.

Every cell expresses the aromatase enzyme, which is the rate-limiting step in synthesizing estrogen. So, anything that that inhibits aromatase, you know, basically will decrease the production of estrogen.”

• Toxic chemicals all around you fuel cancer risk — Dinkov explained that pesticides, plastics, and even foods like soy and flax carry compounds that act like estrogen once they enter your body. These are known as endocrine disruptors, and according to him, they create a constant state of estrogen dominance.

• Blue light exposure fuels cancer — Dinkov pointed out that the vast majority of people are exposed to blue light via fluorescent bulbs, which affect your health:

“Our mitochondria does not like blue light because blue light is toxic to bacteria, viruses, fungi, all these primitive microorganisms, which is probably another corroboration of the theory that mitochondria is originally, such an organism that fused with our primitive human cells because blue light is toxic to mitochondria as well.”

• Other side effects of blue light — Aside from increasing your risk of cancer, Dinkov noted that blue light affects your health in different ways. For example, if you sit under it for hours a day, such as being in an office, you’ll eventually develop headaches, cognitive disturbances and increased risk of mental health disorders.

• Killed cancer put your immune system on overdrive — Once you kill cancer cells through pharmaceutical drugs, the debris acts like a danger signal to your body. The immune system reacts as if you are under attack from a major infection, spreading inflammation throughout your body. “A lot of the mitochondrial debris and the debris from the nucleus trigger the exact same pathways and receptors that bacteria or viral infections trigger,” he says.

• Inflammation shuts down your body’s preferred energy system — Oxidative phosphorylation takes a back seat. When that switch is flipped, healthy tissues across your body start acting more like cancer cells. “The entire body says, I’m under attack,” he explained, which pushes cells into the cancer metabolism instead of restoring balance.

This helps explain why many people see their cancer return after initially successful treatments. Dinkov said that doctors are very good at killing the primary tumor, but the aftermath often leads to scattered, aggressive new tumors appearing throughout the body. He described this as turning “a million little cancers, and it’s all over the body” because the environment has been shifted into the wrong metabolic state.

• Returning cancer cells to normal before apoptosis — Instead of going to war with cancer right away, Dinkov suggested another path. He argued that cancer cells can be coaxed back to normal function if energy production is restored:

“[M]ost cancer cells are still structurally normal, they are metabolically deranged, but they’re still normal. Some of them are too damaged, but it looks like there’s a small percentage. So really, the goal should be don’t immediately go on an all-out assault, right, which, it turns out to be self-destructive. Try to coax the cancer cell to act normal again and that can be done metabolically with various approaches.”

• Simply share the information — Instead of chasing recognition, Dinkov said he focuses on getting information directly to people. He’s already received confirmation from doctors around the world who are quietly using his protocols. One oncologist in Ireland, for example, emailed him saying several patients had their surgeries canceled because their tumors had completely disappeared.

• Nefarious forces are pushing back — Dinkov also pointed out how easy it is for his research to be challenged. Powerful interests in the cancer industry could run the same experiments and report different results. If that happens, journals often retract the original paper, which damages the credibility of the scientists involved. That fear, he said, is one reason many professors refuse to publish such controversial work, even if the data looks strong.

• Big Pharma wants to preserve the status quo — Dinkov noted that even if human trials confirm his approach, powerful resistance will remain. Cancer treatment today is a massive industry, and anything that threatens its profit model faces enormous barriers. For him, the biggest confirmation may not come from journals but from a grassroots movement of patients and doctors who have proven results:

“[I]f it works for sufficiently large number of people, then I don’t need to publish. In fact, I don’t care about publishing. Why do I need to give the enemies a sign that, you know, we’re brewing a resistance here and the resistance is working?”

• Aspirin — You might think of aspirin only for pain or fever, but Dinkov described how it works inside your cells to slightly lower their internal pH. This acidic environmental shift gives cells a choice — if they’re still repairable, they switch back to the healthier oxidative phosphorylation, but if they’re too damaged, they self-destruct through apoptosis.

• Carbon dioxide (CO₂) — When you increase CO₂ in your body, it moves through your cells like a current, carrying electrons and helping energy flow more smoothly. Dinkov described carbon dioxide as doing the opposite of lactic acid — it encourages proper energy production and slows down cancer metabolism:

“[T]he acidic nature of the carbon dioxide molecule, it draws electrons across the cell as it moves, as it diffuses out of the cell. And that helps speed up the oxidative phosphorylation reaction. Also, carbon dioxide and lactate are inversely correlated in the body.”

• B vitamins — Vitamins B1 and B3 act as cofactors. Without them, the electron transport chain stalls out, and cells can’t make enough energy. In Dinkov’s research, combining aspirin with these nutrients restored energy flow in cells that had been struggling.

• Hormones — These include pregnenolone, which Dinkov described as the “structural cell stabilizer,” and testosterone. As mentioned earlier, progesterone blocks estrogen’s harmful effects as well. To learn how to use it properly and optimize your health, follow the instructions in the following sections.

• Healthy adults taking 4 grams of acetaminophen daily developed spikes in liver enzymes within just a week — These enzymes are markers of liver stress. Other cases involved individuals who were malnourished, drinking alcohol, or living with chronic liver disease — all conditions that lower your body’s ability to defend against toxins. Children were also affected when caregivers miscalculated dosages or used adult-sized tablets, showing that no group is fully protected from harm.

• Signs of liver harm were seen in more than three-quarters of participants — In a clinical trial cited by LiverTox, 76% of participants taking high therapeutic doses of acetaminophen developed liver enzyme elevations above the normal range.

Within this group, 39% had levels more than triple the normal limit, while 25% showed increases greater than five times the upper limit. These results are striking because the participants were otherwise healthy adults, not people with pre-existing disease. The numbers make it clear: even “safe” doses often overwhelm the liver in a matter of days.

• Acetaminophen toxicity develops in a predictable timeline — Within 24 to 72 hours after overdose, enzyme levels skyrocket — often reaching values over 2,000 units per liter, compared with a normal of less than 40. By 48 to 96 hours, patients present with jaundice, confusion, and even signs of acute liver failure.

This progression is not limited to intentional overdoses; so-called therapeutic misadventures, when people unknowingly take multiple products containing acetaminophen, follow a similar pattern.

• The danger comes from a toxic breakdown product — Normally, your liver quickly detoxifies this by using glutathione, your body’s master antioxidant. But once glutathione stores run low — whether from poor diet, alcohol, illness, or simply too much acetaminophen — the toxic compound builds up.

When that happens, the breakdown product binds to important proteins inside liver cells, triggering cell death through apoptotic pathways. This explains why acetaminophen injury is so sudden and severe.

• Misuse occurs because people see Tylenol PM as harmless — However, it combines acetaminophen with diphenhydramine — a double hit for your body. Acetaminophen places stress on your liver, while diphenhydramine, the same ingredient found in Benadryl, blocks acetylcholine, a brain chemical involved in memory. In his words, regular use “could cause memory loss” and contribute to long-term cognitive decline.

• Details on liver risks — If you take more than 4,000 mg of acetaminophen in a day, which equals eight Tylenol PM pills, your liver becomes overwhelmed. When that happens, a toxic byproduct accumulates and binds to proteins in liver cells, causing direct injury and setting the stage for organ failure. Melillo stressed that many people don’t realize how many products also contain acetaminophen, so stacking multiple medications raises the risk without you knowing it.

• Concerns about brain health — Diphenhydramine brings its own set of issues. Because it’s a type of drug that blocks signals in your brain needed for memory, focus, and learning, it interferes with acetylcholine, the chemical your brain uses to carry out those functions.

Blocking this pathway leads to short-term drowsiness, which is why people take it to sleep. But with regular use, the tradeoff is much larger: impaired memory and a higher risk of dementia. A study cited in the report found that taking anticholinergics daily for the equivalent of three years was linked to a 54% increase in dementia risk compared with shorter-term use.⁴

• Behavioral changes and risk perception — Another surprising finding tied to acetaminophen is its effect on decision-making. In one study, participants who took 1,000 mg rated risky activities like bungee jumping and skydiving as less dangerous compared to those who took a placebo.

Researchers from The Ohio State University concluded that acetaminophen dulls both emotional responses and risk awareness, creating a subtle but important shift in how people judge danger.⁵ This means your nightly pain pill not only stresses your liver and brain but also changes the way you perceive everyday risks.

• Long-term acetaminophen use was linked to a wide range of serious complications — These included gastrointestinal bleeding and ulcers, increased risks of heart failure and high blood pressure, and a higher incidence of chronic kidney disease. For patients, this means that the very drug prescribed as a “safer” alternative to nonsteroidal anti-inflammatory drugs (NSAIDs) brought with it a nearly identical burden of systemic risks.

• The study revealed a sharp increase in gastrointestinal harm — Participants on long-term acetaminophen therapy experienced significantly higher rates of stomach and intestinal bleeding, ulcers, and even perforations, which are tears in your stomach lining. These complications were once thought to be mostly tied to NSAIDs like ibuprofen, but this study revealed that acetaminophen carries similar dangers when used habitually in older adults.

• Serious impact on the heart — Regular users of acetaminophen showed increased risks for both heart failure and high blood pressure. Heart failure means your heart cannot pump blood efficiently, while high blood pressure places constant strain on blood vessels.

• Chronic kidney disease also emerged as a serious risk for long-term users — Kidneys are responsible for filtering waste products from your blood, and the study indicated that sustained acetaminophen intake accelerates their decline. For older adults already dealing with reduced kidney reserve, the drug placed an added burden that increased the likelihood of progressing to advanced kidney disease.

• How acetaminophen harms your organs — The researchers found that acetaminophen disrupts your body’s normal protective systems. It lowers the amount of natural chemicals that keep blood flowing to your kidneys, help control blood pressure, and protect your stomach lining. When prostaglandins drop too low, your stomach, heart, and kidneys lose that protection. Over time, this makes these organs more likely to get damaged, which matches the problems seen in the study.

1. Avoid acetaminophen whenever possible — Your first line of defense is simply not reaching for acetaminophen unless it is absolutely necessary. If you’re dealing with a mild headache, sore muscles from exercise, or day-to-day joint stiffness, avoid defaulting to Tylenol or Tylenol PM.

The science shows these small, routine doses still place stress on your liver over time. Shifting your mindset to view acetaminophen as a last resort instead of a first choice is one of the most powerful steps you can take.

2. Explore natural pain relief alternatives — Many safe options exist that help with pain and inflammation without damaging your organs. Consider turmeric or curcumin for joint pain, magnesium for muscle relaxation and cramps, or herbal remedies for chronic pain.

If you’re struggling with sleep, calming herbal teas such as chamomile and attention to better sleep hygiene ease you into rest without the brain risks linked to diphenhydramine. These choices don’t just dull symptoms — they support whole-body health.

3. Strengthen your body’s defenses with food — Since acetaminophen damages your liver by depleting glutathione, your best long-term protection is keeping glutathione strong. Eat sulfur-rich foods like garlic, onions, and broccoli, which help your body produce more of this key antioxidant.

If you frequently experience aches, focusing on nutrition gives your liver resilience while also addressing the root causes of pain, such as chronic inflammation or oxidative stress. N-acetylcysteine (NAC) also boosts production of glutathione.

4. Understand the role of NAC in emergencies — NAC is the emergency antidote used in hospitals for acetaminophen overdose because it replenishes glutathione so quickly. If you accidentally take too much acetaminophen, NAC is lifesaving. While you should not rely on NAC as a routine “safety net” for daily use, it’s important to understand how it works. By boosting glutathione, NAC helps neutralize acetaminophen’s toxic byproducts and prevents catastrophic liver failure.

5. Adopt lifestyle strategies that lower your need for painkillers — Daily walks, stretching routines, stress management, and good sleep habits all reduce your reliance on pills. If you’re an older adult dealing with arthritis or chronic pain, gentle movement practices like yoga or tai chi are especially helpful.

These daily steps lower inflammation, support circulation, and help you feel more comfortable without reaching for acetaminophen. By building these habits, you put yourself in control of your pain management instead of depending on a drug that carries hidden risks.
