If you’re searching for the best non-toxic period underwear, I completely understand the desire for peace of mind—knowing your period panties are both PFAS-free and made with safe, natural materials. In this guide, we share personal experiences and expert insights on non-toxic, organic period underwear brands that put your health first.
When I learned that even some popular period underwear could contain PFAS (so-called ‘forever chemicals’), I was shocked: During my search, I discovered that nearly 65% of period underwear may contain PFAS.
These chemicals are added to some textiles to make them “moisture-wicking” or “stain-resistant.” Yet they can build up in your body and have been linked to hormone disruption, fertility issues, and even some cancers. A 2020 report found high levels of PFAS in Thinx’s period underwear, raising awareness about toxins in menstrual products.
As someone committed to non-toxic lifestyle, I've spent countless hours researching, testing, and personally wearing these period underwear options to create the most comprehensive, science-backed guide available. So I’ve put together this guide on the best non-toxic period underwear that’s free of PFAS and made with safer materials.
Plus, I’ll walk you through exactly what to look for when shopping for clean period products and how to avoid sneaky, misleading claims. Let’s dive in!
What Period Underwear is Non-toxic?
Non-toxic period underwear aims to avoid using problematic chemicals like PFAS. Many brands rely on natural fibers such as seaweed viscose yarn, bamboo yarn, or organic cotton for solid absorbency without exposing you to worrisome toxins. In practical terms, “PFAS-free” means you’re sidestepping chemicals that can linger in your body and potentially mess with your hormonal balance.
Why Choose PFAS-Free Period Underwear?
Per- and polyfluoroalkyl substances (PFAS) are manmade chemicals often used to give fabrics that “stain-resistant” or “leak-proof” quality. But PFAS don’t just wash out—they can accumulate in your body over time, and research links them to all kinds of reproductive and hormonal issues. As someone who cares about clean living, I definitely don’t want these “forever chemicals” near my most sensitive areas.
Here's what experts say about PFAS effects:
-
Bioaccumulation: These long-lasting chemicals build up in your body over time. PFAS can remain in human blood for up to 8 years after exposure, with studies showing that 98% of Americans have detectable levels of PFAS in their bloodstream
-
Immunosuppression: PFAS exposure can affect your immune system.
-
Endocrine disruption: Once PFAS enter your body, these forever chemicals mimic hormones and interfere with their normal functions.
-
Potential carcinogens: PFAS are linked to an increased risk of certain cancers.
One especially concerning detail: the vulva is the most absorbent part of your body, according to experts like Alexandra Scranton from Women’s Voices for the Earth. So if your underwear is laced with PFAS, there’s a direct route for those chemicals to travel into your bloodstream and accumulate in your organs.
Fortunately, more and more brands are stepping up with comfy, toxin-free period underwear. Below, I’ll show you how they work and which ones are the safest.
How Do Non-Toxic Period Panties Work ?
Period underwear has multiple layers: a moisture-wicking top layer (often cotton or bamboo) to keep you dry, and absorbent inner layers (using materials like microfiber or polyester) to lock in fluid.
Importantly, non-toxic brands avoid harmful coatings – being polyester blend does not automatically mean PFAS, as PFAS are special treatments that some brands now eliminate .

How Do We Choose the Best Non Toxic Period Underwear Brands?
We divided our top picks into two categories:
-
"Best" Non-Toxic Period Underwear: These are the purest and safest options. They lean on organic fabrics, hold robust safety certifications like GOTS or OEKO-TEX, and undergo independent lab testing confirming no detectable PFAS. For instance, Lilova states each batch is tested twice. Goat Union publicly shares their lab results, and The Period Company is UL PFAS-FREE certified.
-
"Better" Non-Toxic Period Underwear: These are also PFAS-free, but might not use certified organic fabrics, so there’s a possibility of pesticide residue. They’re still significantly safer than mainstream underwear treated with forever chemicals.

What are the “Best” Non Toxic Period Underwear Brands?
Lilova High-Waist Reusable Period Underwear* (Top Pick)
Best for: Fashionable Designs
Pricing: $34
Certifications: N/A, external laboratories PFAS tests
Materials: GOTS-certified Organic Cotton, TPU (Thermoplastic Polyurethane), Nylon, and Elastane.
Size Range: XS - 3XL
Why We Like It:
If you’re craving a high-waist style that genuinely handles heavy flow, you’ll want to hear about Lilova. I’ve found that it combines comfortable coverage with powerful absorbency—up to 4–5 tampons’ worth—while still feeling surprisingly soft.
In my experience, heavier absorbency can feel a bit thicker, but I’ll take that small trade-off over changing pads multiple times.
Lab tests have shown no detectable PFAS in Lilova’s underwear. If you’ve been on the fence about non-toxic credentials, Lilova delivers. They also use organic cotton against your skin, which many of us appreciate for that softer, safer feel.
So iff heavy-flow nights stress you out, Lilova’s High-Waist can ease that burden. You’ll feel confident and snug, knowing thorough lab testing proves it’s PFAS-free and well-made for overnight security.
Boody Period & Leak Proof Full Brief, Overnight*
Best for: Overnight Use
Pricing: $35.95

Materials: Bamboo Viscose, Cotton, Modal, Seaweed Fiber, Nylon, and Elastane.
Size Range: XS - 3XL
Why We Like It:
Boody’s Period & Leak Proof Full Brief offers a rare combo of luxurious comfort and high performance. Boody’s full brief is one of the best reusable period underwear I’ve tried. I’ve slept so peacefully in Boody’s high-rise briefs. Made from bamboo viscose and cotton, this non toxic period underwear is insanely comfortable and absorbent.
They fit snugly but never feel tight on my belly, even on heavy-flow nights. They’re tested for PFAS (none detected!) and follow OEKO-TEX guidelines for dyes, which is a big relief if you worry about hidden chemicals. Trust me, once you try them overnight, it’ll be hard to go back to your old pads.
Boody also leads on the health front – it’s one of the first brands to obtain third-party PFAS-free certification, so you can trust there are no hidden chemicals. They also use OEKO-TEX-approved dyes and processes, ensuring a safer garment overall.
So if you want a luxuriously soft experience that also keeps you dry on heavier days, Boody is a top contender. It’s a true blend of cozy, safe, and leakproof.
Goat Union Period Underwear Boxer Briefs Boy Shorts*
Best for: Boy Shorts
Pricing: $26.90
Certifications: OEKO-TEX® STANDARD 100
Materials: Bamboo Viscose, Organic Cotton, PFAS-free polyester leakproof Layer, and Spandex.
Size Range: XS - 3XL
Looking for discreet period underwear? Goat Union’s PFAS tested period underwear has you covered. Their boxer briefs provide full protection for moderate flow—They feel invisible under high-waisted jeans and handle moderate flow with ease—no dreaded “diaper” . They work great under high-waisted jeans, staying invisible while keeping you protected.
I love that Goat Union publicly shares PFAS test results, which makes them super transparent compared to some big-name brands.
Goat is comfy, inclusive, and they show you the receipts for being PFAS-free.
The Period Company The Bikini Period Underwear*
Best Affordable
Pricing: $12.00
Certifications: OEKO-TEX® STANDARD 100, Global Organic Textile Standard (GOTS), UL PFAS-FREE certified
Materials: Certified Organic Cotton, Spandex Jersey, Polyester, Polyester PUL
Size Range: XS - 6X
Why We Like It:
The Period Company is known for affordability and a softer, more casual look. If you’re on a budget but still want something you can trust, you might find your match here.
I love that their bikini cut is basically soft cotton with a slightly relaxed fit. It can feel like wearing normal underwear—no fancy lace, just pure functionality. Some folks say it runs a little larger, so if you like snug, you might size down.
The brand focuses on organic cotton, and they’ve tested PFAS-free (Intertek/UL certified). Considering the low price, I’m impressed by how reliable they are, and they’re often recommended as a “first pair” of period panties.
If you need budget-friendly, all-cotton comfort with heavy-flow capacity, The Period Company shines. Don’t expect super sleek styling, but you’ll love that secure and soft feel.
Saalt Seamless Thong
Best for: Thong
Pricing: $29.00
Certifications: B Corp, Plastic Negative
Materials: Nylon, Spandex, and Cotton.
Size Range: XS - XL
Why We Like It:
Saalt is a favorite for anyone wanting sleek, barely-there period underwear. It’s basically “period undies that don’t look or feel like period undies,” if you know what I mean.
I’m personally a huge fan of their Seamless a PFAS-free Thong, non-toxic, eco-friendly alternative to traditional panty liners,—it’s so thin and smooth that you can wear leggings or a body-hugging dress without a trace. The thong absorbs about 1–2 tampons’ worth, ideal for spotting or light days. You can use it to absorb everyday vaginal discharge, light menstrual flow, spotting, and even sweat.
Despite being light and crazy thin, Saalt’s gusset is quick-drying and rarely leaks. On heavier flows, many use their brief or hipster versions, which handle up to 3–4 tampons. If you want minimal bulk yet great coverage, Saalt nails it.
Saalt is OEKO-TEX certified and openly declares no PFAS in their fabrics. They also released third-party testingconfirming no PFAS in their updated collections, so it’s a reliable brand if you want peace of mind. The brand also donates part of its proceeds, so they’re a do-good company, too.
If slim, discreet underwear is your priority—especially on light or moderate days—Saalt offers the perfect blend of style, safety, and performance.
TomboyX Gender-Inclusive Period Underwear
Best for: Gender-inclusive Options
Pricing: $30.20 - $42.70
Certifications: B Corp
Materials: OEKO-TEX Certified Cotton, Spandex, and Polyester.
Size Range: 3XS to 6X
Why We Like It:
I see TomboyX as a haven for those seeking boxer briefs or gender-inclusive designs that don’t look overly feminine. It´s a go-to for inclusive sizing and gender-neutral designs. TomboyX is known for how well their boxer briefs, boyshorts, and trunks fit across all body shapes. What I love most about their period underwear—and what many customers praise too—is how comfortable it feels.
Their period underwear can handle up to 6–8 tampons’ worth—serious capacity! That’s why many trust it for heavy days or overnight.
Additionally, TomboyX menstrual panties tested free of PFOS and PFOA chemicals in a 2020 third-party analysis, so you can shop with confidence. I think they’re especially great if you prefer a more androgynous look.
So if you crave a boxer style that’s size-inclusive and leakproof for heavier flows, TomboyX can give you that effortless, comfy coverage you’ve been looking for—without any toxic chemicals.
What are the “Better” Non Toxic Period Underwear Brands?
LOLA Washable Period Underwear*
Best for: Bikini
Pricing: $24.99
Certifications: OEKO-TEX® STANDARD 100
Materials: Cotton, Lycra, Polyester, and Polyamide.
Size Range: XS - 3XL
Why We Like It:
LOLA made its name with organic tampons and pads, but their period underwear deserves attention, too. I love the way it feels like regular, lightweight cotton undies.
You get an ultra-soft cotton that wicks away moisture and keeps you surprisingly dry. The fit is typically a classic bikini that feels snug without pinching. If you’d prefer something that isn’t bulky or stiff, LOLA could be your go-to.
Though designed for moderate flow (3-ish tampons), I can confirm that they rarely leak.
For a comfy, no-fuss cotton bikini that’s discreet and handles moderate flows, LOLA is a sweet choice. It’s mostly organic, non-toxic, and widely available—an all-around crowd-pleaser.
Why Better?
While these are still PFAS-free, they may not use 100% organic fabrics or hold as many safety certifications. However, they remain safer alternatives to mainstream PFAS-treated underwear.
INNERSY High Waisted Postpartum Period Panties*
Best for: Postpartum
Pricing: $24.99
Certifications: OEKO-TEX® STANDARD 100
Materials: Cotton, Polyurethane Laminate (PUL), and Spandex.
Size Range: XS - 5XL
Why We Like It:
I wish I had these back when I gave birth—I remember how stressful postpartum leaks can be. So if you’re in your late pregnancy, these non-toxic period panties are a must-have. Innersy helps you manage light incontinence, so you can focus on your little one's arrival instead of worrying about unexpected leaks. And they’re free of PFAS (though they don’t detail how they test).
If you want a gentle, high-waisted option that supports postpartum healing or just provides extra tummy comfort, INNERSY can be a lifesaver. They might not hold the biggest flows alone, but they keep most moderate leaks locked in.
Why Better:
The brand claims that its products are PFAS-free, though it doesn’t offer details on third-party testing, aside from its OEKO-TEX certification.
Poppins Period Absorbent Menstrual Underwear
Best for: Absorbency
Pricing: $24.00
Certifications: OEKO-TEX® STANDARD 100
Materials: Cotton/modal blend fabric.
Size Range: XS - 3X
Why We Like It:
If you have a moderate to heavy flow, Poppins Period could be just what you need. This highly-absorbent period underwear is a fantastic option to keep you leak-free throughout your period. Depending on the day, it can serve as your main protection or as a backup alongside a menstrual cup, reusable pads, or non-toxic tampons.
Why Better?
Poppins Period claims its menstrual products are PFAS-free, but the brand only references its OEKO-TEX certification as proof.
Diva Reusable Period Underwear*
Best for: Odor Fighting
Pricing: $30.00
Certifications: B Corp
Materials: Polyester, Rayon, Recycled Nylon, and Elastane.
Size Range: XS - 4XL
Why We Like It:
Diva, famous for its DivaCup, also launched reusable period underwear that feels like normal panties but packs serious absorbency.
Diva’s non-toxic period underwear stands out with its innovative zinc-infused gusset. This addition offers antimicrobial and antibacterial properties, helping to reduce the risk of infections and unpleasant odors. In my experience, they’re so light you forget they’re period panties. If you dislike thick gussets, you’ll appreciate Diva’s “quick dry” technology. You’ll also love how quickly it absorbs menstrual fluids, keeping you fresh and protected all day.
Why Better?
They say they don’t “add” PFAS, but haven’t explicitly proven PFAS-free. If you want a brand known for its menstrual cups and supportive products, Diva might appeal to you, though I’d love to see them do more thorough testing.
Flowette Teen Period Pants
Best for: Teens
Pricing: $18.20
Certifications: N/A
Materials: 95% Cotton and 5% Spandex
Size Range: XXS teen - 6XL
Why We Like It:
Looking for teen-friendly period underwear? Flowette focuses on youth sizing and style to help younger folks feel comfy and confident—often for the first time.
The stylish period underwear is the perfect option to help teens feel comfortable during their period. They have bright, fun patterns, plus the sizing is super inclusive. Even though it’s teen-oriented, Flowette can hold up to 40 ml—around 4–5 tampons—enough for many full school days. Some versions go up to 60 ml if your teen’s flow is on the heavier side.
If you want your teen to feel secure and comfortable, Flowette does a stellar job. They’re size-inclusive, truly absorbent, and a real confidence boost for younger users or anyone who likes a smaller cut.
Why Better?
Because they claim PFAS-free but don’t present any certifications, I’d call this a “Better” choice. That said, it’s still a more reassuring option for a young person than big-brand underwear with no transparency at all
With so many PFAS-free and non-toxic period underwear brands on the market, it can be confusing to pick just one. I’ve found each of these 11 options has its own specialty:
-
Lilova or The Period Company for serious overnight absorbency.
-
Boody or LOLAs if you love ultra-soft, organic-based comfort.
-
Goat Union, TomboyX, or Saalt if you want brand transparency and a range of styles (boxers, thong, etc.).
-
Poppins Period for all-day heavy-flow wear with minimal changes.
-
Diva if you’re already loyal to DivaCup’s reliability.
-
Flowette if you’re looking for teen-friendly sizing.
-
INNERSY if you want budget-friendly, high-waisted postpartum or everyday comfort.
Regardless of which brand you choose, know that all these options focus on safer materials, user comfort, and actual performance. Ultimately, you’re the expert on your own flow, lifestyle, and style preferences.
My biggest tip is: start with a pair that speaks to your main priority (heavy flow, invisibility, or cost), see how it fits your routine, and build from there.
Curious why non-toxic period underwear is worth the switch? Let’s break it down
Benefits of Non Toxic Period Underwear
Making the switch to non-toxic period underwear can provide:
-
Reduced Risk of Irritation & Allergies: Conventional period products contain harmful materials that might irritate your sensitive skin, trigger allergies, or cause textile dermatitis.
-
Fewer Vaginal Infections: Board-certified OB-GYN Alyssa Dweck explains that synthetic fabrics can trap moisture, potentially leading to yeast infections.
-
Reduced Exposure to PFAS: Polyfluoroalkyl substances can lead to fertility issues, period irregularities, liver damage, high cholesterol, and even breast cancer.
But here’s the catch: not all brands labeled “non-toxic” genuinely are. That’s why being an informed shopper is so essential.
Imagine my surprise when I found out how loosely regulated period products are. It’s not mandatory for companies to disclose all ingredients. Some other brands even claim they’re “safe” or “green,” but behind the scenes, they’re using chemicals like PFAS.
Thinx is a prime example: it marketed itself as clean and revolutionary, but a 2020 report revealed high PFAS levels in its underwear. Clearly, it pays to ask tough questions and do a little extra research, because your body deserves nothing less.
How to Find Safe, Non-Toxic (Organic) Period Panties
To ensure your period underwear is truly non-toxic, keep these tips in mind:
-
Materials & Certifications: Prioritize period underwear made primarily from natural fibers or non toxic fabrics, such as organic cotton. Look for GOTS-certified organic cotton or OEKO-TEX® Standard 100 certification, which means the fabric was tested for harmful substances . These ensure your undies are free from pesticides, formaldehyde, and other toxins.
-
Third Party PFAS Testing: There are around 15,000 PFAS, but most certifications only test a few. Only buy from brands that clearly state they are PFAS-free. Some brands provide third-party test results – for instance, Goat Union publicly shares its lab test reports confirming zero PFAS . Transparency is a good sign.
-
Absorbency & Layers: Check how much each pair holds (e.g., “holds 3 tampons worth”). Multi-layer designs without toxic coatings can still be very absorbent. Ensure the brand specifies being PFAS-free despite high absorbency.
For a quick check, see if brands publish PFAS test results. If they’re transparent—like Lilova or The Period Company—you’re more likely getting truly non-toxic period underwear. If not, be cautious.
Key Takeaways
When choosing period underwear, prioritize products made with natural, breathable materials that explicitly state they are PFAS-free. While period underwear can be a safe and sustainable menstrual product option, the specific materials, proper hygiene practices, and transparency from manufacturers all play important roles in ensuring both safety and comfort.
-
PFAS Exposure: Most period panties contain PFAS. These forever chemicals can accumulate in your body, increasing the risk of scary health issues like infertility and cancer.
-
Sensitive Area: Your vulva is the most absorbent part of your body. If your period underwear contains PFAS, they will make their way to your bloodstream and organs faster.
-
Greenwashing: Many period underwear brands claim to be "non-toxic" and "PFAS-free," without providing evidence to back up this claim. Always opt for brands that provide independent lab testing or trusted safety certifications.
FAQ to Nontoxic Period Panties
Is period underwear safe?
Period underwear can be a safe and sustainable alternative to traditional sanitary products when made with appropriate materials like organic cotton, seaweed viscose yarn, bamboo yar, etc. However, there are concerns about some period products containing PFAS, which are potentially harmful chemicals. The safety of period underwear largely depends on the specific materials used and manufacturing processes employed, with many companies now prioritizing non-toxic options.
How do I know if my underwear has PFAS?
Looking for explicit "PFAS-free" labeling on products or contacting manufacturers directly to inquire about their use of PFAS in their products is a practical approach. Professional testing for PFAS requires specialized laboratory equipment like liquid chromatography tandem mass spectrometry, which isn't accessible to most consumers. Products marketed as water-resistant, stain-resistant, or "leak-proof" without specifying PFAS-free status might contain these chemicals. Look for third-party certifications, such as GOTS, USDA Organic, or OEKO-TEX Standard.
Can period underwear cause yeast infections?
According to research, bacterial growth on underwear products can result in health issues including yeast infections, rashes, and other discomforts. Wearing breathable cotton underwear is recommended to help prevent yeast infections, suggesting that period underwear made with breathable, moisture-wicking materials would be helpful.
