Zavi Hamilton created Endo Vitality with one goal: deliver a simple, effective solution for people who push through life despite menstrual pain. As a mom, project manager, and lifelong problem-solver, she designed our signature six-chamber heating pad to be portable, reliable, and built for real daily use - from classrooms to campus move-in to busy workdays. Her mission is clear: no one should have to miss life because of pain.
For everyone with period pain. TM
You’ve just discovered the best-kept secret in period pain support: the official portable heating pad.
No more sitting through class, work, or out and about doubled over in pain. Whether your cramps are mild or severe, it’s time to ditch the bulky old heating pad and upgrade your experience.
Our discreet, all-natural pads stick right to your underwear and deliver up to 8 hours of soothing warmth. Anytime. Anywhere.
Our Motto: For everyone with period pain.
What's the Hype? 👀
Our ultra-thin design fits in your purse, bag, bookbag, pocket...practically anywhere.
No one knows you're wearing it.
Cheaper than the daily Starbucks/energy drink.
For cramps, lower back aches, stress, or abdominal discomfort.
Every pop-up table represents more than product sales - it’s where Endo Vitality meets real people who are navigating real pain. Zavi shows up in communities, campuses, and local events to engage face-to-face with students, parents, and young women who need accessible, portable relief.
These moments drive the brand forward: listening, educating, and understanding what people truly struggle with day to day. Her hands-on presence ensures every product is built around the lived experiences of her community, not assumptions.
This is where connection becomes innovation one conversation at a time.
Zavi’s mission extends far beyond selling heating pads it starts with education. She partners with students, clinics, and wellness shops to break down menstrual health myths, explain practical pain management strategies, and create spaces where questions about wellness are welcomed, not dismissed.
Every conversation is an opportunity to empower someone who’s been silently dealing with discomfort or missing class because of pain. By leading with clarity, empathy, and real-world guidance, she connects young people to tools that help them show up fully.
The goal is simple: informed students make healthier, more confident decisions.

Sea Salt → a natural conductor that boosts the heating process.
Purified Water → kickstarts the natural reaction for steady warmth.

Questions?
We Have Answers.
Q: Is it safe?
A: Yes! Our pads are made with non-toxic, all-natural ingredients and are for external use only. Always stick to your underwear, not your skin.
Q: How long does the heat last?
A: You can expect consistent, soothing warmth for up to 8 hours.
Q: How discreet is it?
A: Very! The pad is only 125mm wide and ultra-thin. It's designed to be invisible under clothing.
Q: How do I dispose of the pad?
A: Simply throw it in the trash after use. The ingredients are all natural and safe for disposal.
Q: How hot does it get?
A: Each pad warms to around 50–55°C (122–131°F) — about the same as the medium/hot setting on a standard electric heating pad.
Q: Why is it safer than my electric heating pad?
A: Unlike electric heating pads, our single-use pads don’t plug in or overheat from electricity. They provide a steady, controlled warmth that gradually cools down after use. That means no cords, no risk of burns from falling asleep with it, and no fire hazards.
