Your urine holds a wealth of health information through its 3,000 metabolites, but this data usually goes unmeasured. The U-Scan Nutrio cartridge brings precise urine analysis home, tracking four essential markers to help optimize your nutrition with personalized recommendations¹.

The revolutionary U-Scan Nutrio automatically sends urine analysis results to your app, revealing four key nutritional insights about your body's response to different foods.
Ketone levels
Track your Ketones levels which may indicate early signs of shifts in your metabolism, an important aspect of following your health.
Vitamin C levels
Optimize Vitamin C levels to boost iron absorption and antioxidants by tracking your intake.
Bio-Acidity
Regulate your Bio-Acidity to support better bodily function by tracking your pH levels.
HydroStatus
Follow your HydroStatus which may revitalize your body by optimizing fluid intake through specific gravity measurements.

Ketones level
Understanding Ketones
Ketones are compounds produced by your liver when carbohydrate intake is low, forcing your body to use fat for energy instead.
This parameter is particularly interesting for people following keto diets, practicing intermittent fasting, or training as endurance athletes.
Beyond these scenarios, the presence of ketones in urine may also indicate a metabolic shift away from using carbohydrates as fuel. Typically, there should be no ketones present in urine; however, they can appear in the special cases mentioned above. If your ketone levels reach a high level and you are not practicing intermittent fasting or intentionally restricting carbs, it is recommended to take another measurement for confirmation. If the levels are still elevated, consult a doctor. Source

Vitamin C levels
Boost Your Immune System
Vitamin C levels in your urine reflect your intake of this essential nutrient, which supports antioxidant protection, collagen production, immune health, and iron absorption. The presence of Vitamin C in urine typically indicates that your body has met its necessary daily requirement, with the excess being excreted.
Tracking these levels helps ensure you're getting enough, particularly if you're focused on skin health or boosting immunity during cold and flu season.

Bio-Acidity
Balance your diet
Bio-Acidity measures your urine pH, revealing whether your diet is too acidic or alkaline. By tracking levels, you can understand how different foods may affect your body and may help you maintain a better nutritional balance. Source
It may be useful for athletes and anyone tracking their digestive health.

HydroStatus
Find your optimal fluid intake
Your HydroStatus can be estimated by measuring your urine's specific gravity—a comparison of its density to that of water. A higher specific gravity may indicate an insufficient fluid intake. Source
Tracking your HydroStatus may be valuable for athletes aiming to optimize performance and recovery. Source
