Let’s say you're training for a half-marathon. With U-Scan Nutrio’s nutrition-focused cartridge, you can monitor your ketone levels to see if your metabolism is shifting. Not getting enough Vitamin C? It'll flag that. Dehydrated? Your urine’s specific gravity will tell the tale.

For someone with a history of kidney stones, the U-Scan Calci cartridge checks calcium and pH levels—two major risk factors. Combined with fluid balance tracking, it helps users stay ahead of potential flare-ups.

The U-Scan is especially useful for:

• People managing hydration, nutrition, or metabolism
• Athletes fine-tuning performance and recovery
• Individuals at risk for kidney stones or chronic kidney issues
• Anyone looking for deeper health insights—without clinical visits

And because it requires no manual input or tracking, it's accessible even to people who may struggle with traditional at-home tests.

Withings isn’t stopping at nutrition and kidney health. Future cartridges could unlock insights into hormone levels, menstrual cycles, or even early disease detection—turning the toilet into a frontline health monitor.

The company’s subscription model ensures users get fresh cartridges every few months, along with AI-driven insights through its Withings+ ecosystem.

The U-Scan seems promising. Will it catch on? We shall see. Learn more by visiting the Withings website.
