What is Glyphosate?

By now, most people have heard the name glyphosate. Much discussion and debate has surrounded this herbicide, and the potential for glyphosate neurotoxic risks to the human nervous system, but some details still remain obscure.^2,3,5,6

Glyphosate has had a meteoric rise in how and where it is used. Chemistry is a highly complex subject. But even a basic understanding is helpful to understand how glyphosate works as a weedkiller, the ways it can affect human health, and what the downstream consequences might be for the future of our fast-moving modern world.⁷

Glyphosate has been the planet’s most used herbicide for decades. Glyphosate is the active chemical ingredient in the weedkiller known as “Roundup” and is also contained in hundreds of other products used in the agriculture industry. From the farmlands of North America to the wheat fields and orchards of Europe, and other continents, glyphosate products have aggressively found their place in commercial crop production.

Glyphosate began to be used as a non-specific weedkiller in 1974. However, because it is non-specific (kills everything), it resulted in crop losses. Earliest use was limited to clear large weeded areas of land before a construction project, or keeping ditches along the highways clear of weeds, and similar uses. Modifications occurred around the mid 1990s that made the herbicide more attractive for the wider range of commercial food production, which will be discussed in more detail below.

The Glyphosate “Kill Switch”

The way glyphosate kills a plant is by disabling the plant’s ability to uptake and metabolize proteins and other nutrients, causing it to die of starvation in a very short time. Additional ingredients in the herbicide mixtures are there to increase the lethality effects and speed up the process. The blocking of amino acids, and choking the distribution of other nutrients inhibits the production of many other vital components. Comparing this to the biology of humans, glyphosate would be a neurotoxic catastrophe.²⁴

Such a powerful weed-killer could be beneficial to large-scale crop production, backyard gardeners, for effective defoliation in clearing large parcels of land overgrown with weeds, and other uses. The trouble is that glyphosate is non-selective, meaning it kills not just the weeds, but most of the living plants it comes into contact with. Glyphosate can kill the dandelions, but also the corn, the sugar beets, the wheat, and more.

However in 1996 scientists at Monsanto found a way to genetically modify the cells of soybeans. This genetic modification resulted in the creation of “roundup-ready” seeds, making them immune to the “kill switch” effects of the herbicide. GMO (genetically modified organism) soybeans were the first to come to market, resulting in viable large-scale soy production that was resistant to glyphosate. Hence, farmers could spray the entire field of “GMO” soy plants, and kill only the weeds and not the soy. Soon after came roundup ready (genetically modified) corn, cotton, and many other types of seeds.²⁸

However, as the downstream effects of GMOs and the potential neurotoxic risks of glyphosate are still not completely understood, the risk of neurotoxic effects of glyphosate on people and animals has continued to escalate.

Role of Genetically Altered Seed (Roundup Readiness)

To circumvent the potential for large crop losses, genetically altered commercial seed was introduced, widely promoted, and ultimately adopted into the agricultural industry.

As stated above, glyphosate will kill any living plant except those that were grown from seed that was genetically modified to bypass glyphosate’s “kill switch.”

So companies like Bayer (who Monsanto merged with in 2018) have now patented their GMO seeds, requiring the farmer to sign a contract that disallows the farmer from re-planting seeds produced from GMO seed. This creates in effect an on-going seed purchase subscription that the farmer is locked into yearly.

As a result, farmers who have become dependent on Roundup-ready (GMO) seed must re-purchase GMO seeds newly each year. This has replaced the time-honored practice of saving this years seeds for next year’s planting. Roundup-ready seed has in effect created a monopoly on what a farmer is legally allowed to plant.

However, Bayer has paid out over $10 billion so far to settle just a percentage of the claims made against the company for the harms of glyphosate-based products, placing the corporation at risk of bankruptcy.²⁵

More information on the neurotoxic potential effects of glyphosate continues below.

Human Exposures and Neurotoxic Risks associated with Glyphosate

People can be exposed to glyphosate and other herbicides and pesticides through direct contact when the chemicals are applied to crops. Before harvesting, glyphosate is also used as an efficient “desiccant” meant to dry out the moisture of the plants, making them easier to harvest. Crops are sprayed and desiccated several times each season. However, this leaves a residue on the plant materials which might be ingested.^12,19,21-23

If sprayers are used, the chemical mist can drift and be inhaled. Handling wet plants after applying glyphosate is another possible source of contamination. While glyphosate has been the subject of controversy over its level of toxicity to humans, the jury is still out on any downstream effects, especially from either direct contact, or ingesting foods or water that have become laden with these chemicals. The levels may be measurably “low,” but are recurring and ever-present in soil, and other contaminated areas that people will be in contact with. Researchers have voiced concerns that chronic low-level toxic exposure to glyphosate can create disastrous neurotoxic risks to human health that should not be ignored.¹

Groundwater contamination, and soil contamination are 2 other important areas of concern. The half-life of glyphosate in the soil varies greatly from 1 day to 280 days. And one of glyphosates metabolites, amino-methyl-phosphonic-acid (AMPA) has been found to have a half-life of over 900 days. Also, glyphosate can eventually wind up in groundwater, with a half-life in water ranging from a few days to 91 days, and up to 315 days in marine waters. These extended half-life periods present a very real liability of chronic exposure over a significant period of time, to microorganisms, fish and wildlife, farm animals, and people alike.

A study published in the 2022 International Journal of Molecular Sciences reported that glyphosate residue was present in between 60% and 80% of the general population of the United States. And a study published in the Journal of Environmental and Analytical Toxicology demonstrated that glyphosate residues were also detected in the urine of a significant percentage of farm animals tested for glyphosate.^12,19,21-23

Signs of direct exposure to glyphosate can include:

• Irritation or burning of the skin
• Eye or throat irritation or burns
• Respiratory tract inflammation
• Nausea
• Vomiting

The Healthy Human Microbiome vs Glyphosate Exposure

The medical literature on the genetic modification of seeds describes how it disables a pathway necessary for metabolism in plants, essentially starving them to death. For decades, it was proposed that since the human body doesn’t have the same pathway, this meant the product was inert in the human body.

However, it has been discovered that the same pathway that disables plants is also found in microorganisms, such as those found in the human gut microbiome. Concerns have been raised about glyphosate causing a disruption of the bacteria in the gut microbiome, leading to a range of potential harms to health.^{8-11,13-16,20}

This is an important risk to be aware of, because the gut microbiome is where a large percentage of neurotransmitters and hormones are produced. If this hub of the central nervous system becomes dysfunctional, many negative consequences could occur. Glyphosate neurotoxic risks are now being investigated in countless clinical studies across the entire globe.

And an over-arching problem is that these issues could become chronic and disabling over time. More study is called for regarding these important concerns over the neurotoxic risks of glyphosate on the human gut microbiome, as these are still being debated. For instance, the EPA has declared that glyphosate doesn’t cause cancer, while the W.H.O.’s International Cancer Research Agency declared it was probably carcinogenic in humans. The human gut acts as our neurotransmitter “factory” and distribution system, and thus, a functioning microbiome supports life in thousands of ways, all of which are vital for health.^4,5

Negative effects of gut microbiome dysfunction can include:

• Inability to create and distribute vital proteins such as amino acids, which are precursors to creating serotonin, dopamine, glutathione, and more
• Inflammation of, and impairment of the immune system
• Disabled enzymes necessary for metabolism
• Embryo, placenta and umbilical cell damage and cell death
• DNA fragmentation
• Impairment of the mucosal barriers of the intestinal walls
• Dysfunction of the central nervous system
• Increased liability of developing GI and organ disease and other infections
• Prone to lung, respiratory, and cardiovascular disorders
• Can lead to Alzheimer’s disease Parkinson’s disease
• Potential factor in autism and schizophrenic conditions
• Skin disorders
• Obesity (metabolic dysfunction)
• Mood dysregulation
• Decreased cognitive ability
• Impaired neurotransmission and neuronal cell growth and repair

GMO Foods and Alterations to Human & Animal DNA — Researchers Caution

According to a 2019 review on the effects on people and animals eating GMO foods, there is some limited evidence that fragments of GMO food DNA even after processing and digestion can be found in the gastrointestinal tract, the blood, and tissues of both animals and humans. Stronger evidence has shown that gene expression patterns in both animals and humans, however, can be altered by the transference of altered plant DNA material into the microbiota of the gut, and into what are called “somatic cells.”

Somatic cells are cells involved with building and repairing the tissues, and organs that form the body and, importantly, somatic cells include nerve cells.

Somatic cells are not involved in the reproductive pathways or functions of reproduction, not involved with sperm, egg cells, or stem cells according to research published in the International Journal of Food and Chemical Toxicity, and are not affected by modified plant DNA such as DNA from plants which are grown from genetically modified seed.^28,29

However, research is limited which warrants a cautionary approach as the full spectrum of gene transference from altered plant DNA into the human gastrointestinal tract is still in its early stages, and the picture is far from complete, according to a review published in the Journal of Critical Reviews in Food Science and Nutrition.³⁰

Other research echoes the need for caution, as published in the 2022 Frontiers of Bioengineering and Biotechnology Journal. Authors caution that various pathways of gene transfer between species have been underestimated due to the previous deficiency in detection. More effective detection systems are being developed to help regulators and food producers alike to better understand the mechanics and the risks of genetic gene transference.³¹

Learn Holistic Detox Strategies for Glyphosate Neurotoxic Effects

One of the most important things one can do to fight back against potential glyphosate neurotoxic risks is to discontinue using it, stop being exposed to it, don’t use it on your garden or lawn.

The tough thing about glyphosate residue is that you can’t just rinse it off or boil it out of foods. But, there are proven ways to break down the molecular structure of the chemical herbicide residue, and other ways to fight back and achieve very real protection from the harms of chemicals such as herbicides and pesticides used in food production.^{17,18,26,27,32}

Some strategies that can help us to stay healthy can include:

• Use ozone to de-structure the chemical residue on fruits and vegetables before consuming them
• Other types of vegetable soaking products containing vinegar are also available, may not remove all residue
• Peeling or trimming vegetable and fruit skins is recommended
• Binders (capture and eliminate toxic molecules) such as bentonite or other clays, psyllium husk, fruit pectin, used in cleansers to capture and eliminate glyphosate molecules (NOTE: avoid taking such within 2-3 hours of taking medicine or supplements
• Help heal the gut with fermented foods (sauerkraut, kimchi, pickles, yogurt, etc.)
• Probiotics in supplement form
• Prebiotics for microbiota nourishment
• Eat organic foods to avoid those processed/grown with pesticides or herbicides where possible
• Try growing your own vegetables and fruits for the security of knowing they are clean
• Drinking water should be filtered and ozonated, if possible
• Sauna has been found useful for exporting toxins through sweating
• It is also recommended to seek guidance from a naturopath familiar with true detox methods to help you plan the most effective daily regimen.
