The Best Organic Period Panties in 2024!
I don’t know about you, but trying to keep our periods under control while working out, sleeping, or even chilling can be a hassle.
I won’t claim that the best organic period panties below will erase all your menstruation-related anxiety with a swipe. But they’ll undoubtedly eliminate one of the biggest fears:
Toxic chemicals near your most private areas.
Unfortunately, the health and environmental impacts of traditional menstrual products, such as regular pads and tampons, are a cause for concern. These disposable items contribute significantly to plastic menstrual waste, leading to long-term consequences for the planet.
To put this into perspective, a recent study found that an estimated 28,114 tonnes of waste is generated annually from menstrual products.
The conventional manufacturing processes and materials involved in these products often include harmful chemicals, and the disposal of used items adds to the global burden of plastic pollution.
These chemicals, known as PFAS, are called the “forever chemicals“. They resist degradation in the environment and remain in our bodies for years after exposure.
Plus, the synthetic materials used in traditional pads and tampons can irritate sensitive skin, contributing to discomfort and potential health issues such as TTS and infections.
We were shocked when we found out that chlorine is often used to bleach cotton or wood pulp to produce sanitary pads. On top of that, synthetic fragrances are often added to period pads to mask the menstrual odor, which contains various chemicals that can cause skin irritation and allergic reactions.
Non-toxic period underwear, on the other hand, is crafted from sustainable materials and designed for maximum absorbency.
The reusable nature of organic period underwear reduces the generation of plastic waste and can easily cater to individuals with irregular cycles or those experiencing heavier flow days.
Read on to find out more about these reusable game changers and grab a pair of period underwear for yourself!
What are organic period panties?
Organic period panties are a sustainable and zero-waste addition to the world of menstrual products. Unlike regular underwear, these eco-friendly undergarments are crafted from layers of breathable organic cotton and other trusted natural fibers.
This ensures that the fabric is free from harmful chemicals and pesticides throughout the supply chain, making it a healthier and more environmentally friendly choice for your menstrual cycle.
The curve-hugging fit of organic period pants offers maximum comfort and overnight support, especially during heavy flows. They often come with a built-in 4-layer core designed to absorb menstrual flow effectively.
The use of anti-leak technology and high-quality absorbent fabric makes them a reliable choice for everyday wear, even on the heaviest days of a period.
So, ultimately, opting for the best period underwear contributes to reducing plastic menstrual waste associated with disposable period products.
How do non-toxic period panties work?
Non toxic and organic pedion panties incorporate several layers of specialized fabrics to fulfill distinct functions. The top layer, made of moisture-wicking materials, serves to keep the wearer feeling dry by swiftly drawing moisture away from the body.
Beneath this, multiple absorbent layers are strategically placed to trap and hold menstrual fluid securely. The bottom layer is typically crafted from waterproof or water-resistant materials to make sure that absorbed fluids do not leak through the fabric, thus providing effective protection against leaks.
Different absorbency levels cater to varying flow intensities, making period underwear suitable for light to heavy menstrual days.
What toxic chemicals are hiding in most period panties?
Most regular underwear, especially disposable period panties, often contain toxic chemicals that can have adverse effects on health. Some common culprits include polyfluoroalkyl substances (PFAS), often used to make fabrics water-resistant.
- PFAS have been associated with health issues, including hormonal disruption and reproductive problems. In disposable period products, the layers of stitched absorbent material may also contain chemicals that are harmful when they come in contact with the skin.
- Additionally, disposable period panties may contain traces of fluorine measured in parts per million (ppm), posing potential health risks. These chemicals are used for moisture-wicking properties, but their impact on the body, especially in intimate areas, raises concerns.
- Regular pads and disposable period underwear, often made from synthetic materials, contribute to plastic menstrual waste, creating environmental challenges. The convenience of these disposable products comes at the cost of the planet and potentially your health.
Choosing organic period panties eliminates exposure to these toxic chemicals, providing a safer alternative for your menstrual cycle.

What’s wrong with PFAS in period underwear?
Current peer-reviewed scientific studies have shown that exposure to certain levels of PFAS may lead to reproductive effects, including decreased fertility or increased high blood pressure in pregnant women, developmental effects or delays in children, increased risk of some cancers, including prostate, kidney, and testicular cancers, reduced ability of the body’s immune system to fight infections, interference with the body’s natural hormones, and more.
Are all period underwear brands safe?
Well, not exactly. Some well-known companies use synthetic fibers like polyester and other petroleum-based materials to create period undies.
While not all polyester contains PFAS (yes, there are third-party-tested safe polyester undies), they can be found in alarming numbers when a brand does not properly test for it and make it part of their production process.
In the last few years, some of the most popular period underwear brands that claimed to be non toxic and organic were charged with selling period panties with forever chemicals (PFAS) in their period underwear.
When you opt for the best organic period panties, you can rest assured knowing you’ll get the best possible leak-proof protection minus the harmful chemicals.
What is the best PFAS-free material for period panties?
The best and safest material for period panties is organic cotton. Organic period panties are breathable and hypoallergenic, which helps prevent moisture buildup, making them a comfortable choice for long-term wear during menstruation.
Additionally, organic cotton can absorb moisture and prevent leaks. In other words, it’s ideal for folks with medium-heavy periods.
Which period underwear is the least toxic?
There are many options if you are looking for non-toxic and PFAS-free period panties. Wuka, Mobibodi, and Tomboy X are size-inclusive brands that use certified organic cotton, bamboo viscose, and merino wool to create sustainable & organic period underwear.
Lesser-known brands like Aisle and AWWA also offer toxic chemical-free period products that are safe for the skin and the environment. Look at our top picks below for your new zero-waste period soul mate!
How to properly wash organic period underwear?
Rinse Immediately! After use, rinse the underwear under cold water as soon as possible to help prevent stains from setting.
- Pre-Treat Stains: If there are any stubborn stains, you can pre-treat them before washing. Apply a small amount of mild, bleach-free detergent or stain remover directly to the stained area. Gently rub the fabric together to work in the detergent.
- Machine Wash: Most period underwear can be machine washed. Place the underwear in a mesh laundry bag to protect them and prevent them from getting tangled with other items. Use a gentle cycle with cold water to help preserve the fabric and prevent any damage.
- Choose The Right Detergent: Use a mild, fragrance-free, and eco-friendly laundry detergent that doesn’t contain bleach or fabric softeners. These additives can affect the absorbency of the fabric and may cause irritation.
- Avoid Fabric Softeners and Bleach: Fabric softeners can leave a residue on the fabric and reduce absorbency, so it’s best to avoid using them. Similarly, bleach can damage the fibers and affect the performance of the period underwear.
- Dry Carefully: Air-dry your period underwear whenever possible. Avoid using a tumble dryer, as high heat can damage the fabric and elastic. Hang the underwear to dry or lay them flat on a clean, dry surface. Direct sunlight can help eliminate bacteria and odors naturally.
- Check Manufacturer Instructions: Always check the care instructions provided by the manufacturer. Different brands may have specific recommendations for washing and caring for their products.
- Avoid Hot Water: Stick to cold or lukewarm water for washing. Hot water can damage the elastic in the underwear and reduce its lifespan.
- Hand Wash Option: If you prefer, you can also hand wash your period underwear. Use a gentle detergent, and follow a similar process to the machine wash instructions.
