GMO & Glyphosate Study Guide

Cotton. Fields of soft, innocent fluff balls. In our clothing, bandages, bank notes annnd feminine hygiene products. Not so long ago, "100% cotton" was a seal of honest natural quality. 


now, more often than not, cotton is genetically modified. 

GMOs, or genetically modified organisms, are plants, animals & other organisms whose makeup has been altered to a state of genetic combinations that don't occur in nature, or through traditional cross-breeding methods. According to the USDA, 89% of cotton planted in the U.S. is genetically engineered.

New "breeds" of plants are designed to: increase the volume of crops from a single seed, speed up the growth process or be more resistant to herbicides & other chemicals. 

A farmer can now spray her fields to kill pesky weeds without damaging her crops. But in fact, her crops are damaged. Now they contain chemicals, the most common of which is glyphosate.

Glyphosate was brought to the market in 1974 by Monsanto under the commercial name RoundUp. Since then, its usage has only increased. The crops with the highest risk of exposure are corn, soy, sugar beets & cotton. You can expect to find glyphosate in many products derived from these crops.

even in cotton products like tampons & pads?

Yup. A 2015 study tested cotton-based products like tampons, pads, swabs & wipes. Glyphosate was found in 85% of the tested products.

If it's in our products, our body will absorb it. Studies have found glyphosate in urine, blood & breastmilk

So what's the big deal? The World Health Organization has concluded that glyphosate is a probable carcinogen. Evidence confirming glyphosate's damaging health effects is mounting. Studies have linked glyphosate to autism, Alzheimer's disease, hormonal imbalances, infertility, gastrointestinal disease, cardiovascular disease, depression, obesity & allergies.

Tampons & pads made with GMO cotton are more than likely to contain glyphosate. Opting for 100% certified organic cotton is the only sure way to avoid it & keep your fields fertile.


  • is a harsh herbicide linked to disease

  • is often found in genetically modified organisms (GMOs)

  • lurks in the majority of non-organic cotton-based tampons & pads

  • can be avoided by choosing organic products
