KRAMPZ
100% drug-free menstrual pain relief patches developed
with infrared technology.
A new kind of period care that targets menstrual pain, at the source.
During menstruation, uterine contractions restrict blood flow and reduce oxygen delivery to the uterus,contributing to menstrual pain, cramps, and discomfort.
Krampz Menstrual Pain Relief Patches are clinically tested and shown to increase localized blood circulation and oxygenation where patches are applied—100% drug-free
Why Period Pain Happens
Your body goes through a chain reaction every cycle. Here’s what’s actually happening — step by step.
Prostaglandin Release
When progesterone levels drop at the end of your cycle, the uterine lining releases prostaglandins — chemical messengers that trigger powerful contractions.
Uterine Contractions
Your uterus contracts to shed its lining. Those contractions can temporarily restrict blood flow and reduce oxygen delivery to surrounding tissue.
Restricted Blood Flow
When circulation is restricted, less oxygen reaches your uterine tissue. This localized reduction in blood flow and oxygen delivery creates a low-oxygen environment in the surrounding tissue.
Pain Signals Intensify
Restricted blood circulation and reduced oxygen amplifies pain signals throughout the pelvic region, making an already uncomfortable process considerably more intense for many people.
Menstrual Pain.
That reduction in circulation and oxygen delivery is associated with the cramping, aching, and throbbing many people experience each cycle.
Krampz Patches are clinically tested
and shown to increase localized blood circulation and red blood cell flux (oxygenation) where patches are applied—
a statistically supported increase observed across all measured intervals.
WHY THIS IS IMPORTANT: Restricted blood circulation and reduced oxygen is what turns a contraction into the cramp you feel. Krampz patches support your body’s ability to deliver oxygen back to that tissue.
Data & Testing
A clinical trial conducted by independent university researchers utilized Portable Laser Doppler Flowmetry. Participants were tested using randomized, controlled methodology with bilateral comparison. The patched side demonstrated greater flux and cutaneous temperature values compared to the unpatched side. A statistically supported increase in localized blood circulation was observed across all measured intervals.

Deep energy.
Beyond the surface.
Far-infrared energy is invisible light energy with wavelengths between 4–16 micrometers (μm). The therapeutic range of8–14 μm overlaps with the human body’s natural thermal emission — the same range in which the human body itself radiates heat. When far-infrared in this range interacts with your body, it is absorbed as what researchers describe as wavelength resonance. Krampz mineral-enhanced Circle and Lightning Bolt infrared zones are activated by your body’s heat to deliver far-infrared energy exactly where the patch is placed.
Unlike heating pads that warm from the outside in, the body experiences far-infrared as gentle radiant energy that can penetrate up to 4cm or 1.5in through skin tissue to reach deeper layers — without feeling any noticeable surface heat. This may include muscle, joints, and other tissue. Heating pads typically penetrate 0.25cm to 2cm into the skin.
Far Infrared & Krampz
- Krampz patches include mineral-enhanced Circle and Lightning-Bolt Infrared Zones which emit far infrared energy.
- Krampz patches capture your body’s heat and convert it back as infrared energy.
The Drexel University Emissivity Study
Independent researchers tested Krampz patch technology. The result: far-infrared emissivity with peak performance in the8–12 μm range — the same band in which the human body naturally emits thermal energy.
Avg. 14 scans ▪ peak performance range (8–12 μm) ▪ Human body natural emission: 8–14 μm
