Polysorbate 80, what is it good for? Absolutely nothing except for dysbiosis, leaky gut, and other gut ailments

Why be critical of Polysorbate 80?  Because it's in most nicotine products, like lozenges and patches.  

Polysorbate 80, a common emulsifier in food, cosmetics, and pharmaceuticals, is generally recognized as safe by regulatory agencies like the FDA and EFSA when used within approved limits. However, some studies and concerns suggest potential adverse effects on human biology, particularly at high doses or with chronic exposure. Below is a summary of the potential harms based on available evidence: GUT HEALTH DISRUPTION Mechanism: Polysorbate 80 may alter the gut microbiota and compromise the intestinal barrier. Studies in mice (e.g., Chassaing et al., 2015) showed that it promoted inflammation and dysbiosis, contributing to conditions like colitis and metabolic syndrome.

Human Relevance: While human studies are limited, these findings raise concerns about chronic consumption, especially in individuals with pre-existing gut issues like inflammatory bowel disease (IBD). It may increase intestinal permeability ("leaky gut"), potentially allowing harmful substances to enter the bloodstream. Immune System Effects Inflammation : Polysorbate 80 has been linked to low-grade systemic inflammation in animal models, which could exacerbate chronic diseases in humans, such as obesity or cardiovascular conditions. 

: Rare cases of hypersensitivity or anaphylactic reactions have been reported, particularly in intravenous medications containing polysorbate 80 (e.g., in some vaccines or chemotherapy drugs). Potential Carcinogenicity Concerns Contamination Risk : Polysorbate 80 can contain trace amounts of ethylene oxide or 1,4-dioxane, both classified as potential carcinogens. Regulatory bodies set strict limits to minimize this risk, but long-term exposure to low levels remains under scrutiny. Animal Studies : High doses in rodent studies have shown no direct carcinogenic effects, but the data is not conclusive for humans. Hormonal Effects : Some in vitro studies suggest polysorbate 80 may interfere with estrogen signaling or other hormonal pathways, potentially acting as an endocrine disruptor. However, human evidence is sparse and inconclusive. Reproductive Health : Animal studies at high doses have indicated possible effects on ovarian function or fertility, but these findings are not directly applicable to typical human exposure levels. Metabolic and Cardiovascular Impact

:

Metabolic Syndrome : As mentioned, animal studies link polysorbate 80 to metabolic disturbances, including obesity and insulin resistance, possibly via gut microbiota changes. Cardiovascular Risk : By promoting inflammation or altering lipid metabolism, chronic exposure might indirectly contribute to cardiovascular issues, though direct evidence in humans is lacking. Toxicity at High Doses : At very high doses (far exceeding typical dietary or pharmaceutical exposure), polysorbate 80 can cause gastrointestinal distress, kidney damage, or hemolysis (red blood cell destruction) in animal studies. Human Exposure : Normal consumption levels (e.g., in processed foods like ice cream or salad dressings) are well below these thresholds, with an acceptable daily intake (ADI) set at 25 mg/kg body weight by the WHO. Key Considerations

Dose-Dependent Effects: Most adverse effects are observed at high doses in animal studies, which may not reflect typical human exposure through food or cosmetics: People with compromised gut health, allergies, or chronic inflammatory conditions may be more susceptible to potential harms.

Regulatory Oversight: Agencies like the FDA and EFSA have deemed polysorbate 80 safe within specified limits, but critics argue that cumulative exposure from multiple sources (food, drugs, cosmetics) is understudied.

Limited Human Data: Much of the concern stems from animal or in vitro studies, with few large-scale, long-term human studies available.

Conclusion:

Polysorbate 80 is likely safe for most people at regulated levels, but excessive or chronic exposure may pose risks, particularly to gut health, immune function, and metabolic processes. Those with specific health conditions or concerns about additives may benefit from minimizing consumption of processed foods or products containing polysorbate 80. For personalized advice, consulting a healthcare provider is recommended.

RILEY CHECK: Johnson & Johnson has been around for 139 years and never cured anything. Pfizer has been around for 175 years and never cured anything . . . .

Sounds right. https://t.co/zS8Mb8xqSf

Johnson & Johnson has been around for 139 years and never cured anything. Merck has been around for 134 years and never cured anything. Pfizer has been around for 175 years and never cured anything. These companies ONLY make deadly drugs and vaccines. Shut them down!

1964, Merck produced Adjuvant 65 that contained 65% peanut oil plus Arlasel A, aluminum stearate. Beginning in the 1970s, INJECTING peanut oil became common in vaccines

☝️Vaccines are 100% responsible for all food allergies. Anaphylactic state is created by injecting common proteins, such as derived from peanuts, wheat, soy, corn, etc. In majority of cases it's not a shock, but slow-burning allergy that makes all food containing these proteins…

Sanofi, Glaxo, Merck, & Pfizer: The 4 companies who make the child vaccine are all convicted criminals.

Since 2009, these 4 companies have paid out over $35 billion dollars in criminal penalties, damages, and civil penalties, for falsifying science, defrauding regulators, lying to the public, and for killing hundreds of thousands of people unnecessarily.  Merck, for example, with one drug, Vioxx, [and here], killed over a hundred thousand; some estimates are as high as 500,000 Americans with a drug they were selling as a headache pill that they knew, the company knew, was going to cause heart attacks but they did not tell the public.  For many of the people who took that drug during that period, if they had known that it could kill them, they might have said, "I'll take an aspirin instead."  But they weren't given that choice because they weren't given the knowledge.  And today we have the same thing, but we have a conspiracy of the government to actually comply . . . Merck ended up paying $7 billion dollars.  The entire board of directors should have gone to prison.  They paid $7 billion dollars in penalties and damages for that case.  Today, we have something much worse: we have government conspiring with those same companies to hide facts about these mandatory vaccines from the public.  And remember . . .
