FAQs
What exactly causes high-performance cramping?
How does the FlashRelease™ ODF strip work?
While often attributed to dehydration, science shows most EAMCs are neurological. It's a motor neuron hyper-excitability glitch. YelloCard targets the TRP receptors in the mouth to send an inhibitory signal that effectively 'resets' the misfiring nerve.
Our Oral Dissolving Film (ODF) technology bypasses the digestive system. By melting on the tongue, the concentrated active ingredients immediately stimulate the sensory nerves that connect back to the spinal cord, halting the cramp at the source without the wait time of liquids.
When is the optimal time to use YelloCard?
Is YelloCard calorie or sugar-free?
The ODF can be used both as a preventative measure when you feel the first 'twitch' of a cramp coming on, or as a reactive treatment for a full-blown contraction. Its ultra-light, foil-wrapped design means you can carry it during any run or ride without bulk.
Yes. YelloCard is engineered for performance, not fuel. Our ODF strips are calorie-free and sugar-free, ensuring they don't interfere with your specific race nutrition plan or cause unwanted stomach distress during high-intensity efforts.
Why ODF instead of liquids?
Does YelloCard replace your water, fueling, or electrolytes?
Nope. Think of YelloCard as your ultimate cramp-control sidekick. It works with your hydration and fueling, never replacing your water or salts.
What age do I need to be to use YelloCard?
Speed and weight. Oral Dissolving Films provide precise dosing without the slosh or gastric distress of liquid alternatives. Plus, at less than 3 ounces, it's the lightest piece of high-performance gear in your kit.
Can I use YelloCard for night cramps?
YelloCard is safe but built for athletic performance. Since night cramps usually aren't neural fatigue, check with your doctor for the best recovery plan.
YelloCard is not ingested and is only a strong stimulus to the receptors within the mouth. It can be used at any age that EAMCs can occur
How many strips should I use?
Is YelloCard sold in stores?
Start with one strip at the first sign of a twitch to reset your nerves quickly. Most athletes feel relief within ninety seconds, but you can safely use another if that stubborn cramp persists.
You can grab YelloCard on Amazon or at select local shops right now. If you want to see us on your own store shelves, reach out through the form above and let's get you stocked.
