Why Managing a Renal Diet Is So Hard

Kidney patients don't just watch one number. They juggle four nutrients across every meal, every day. Existing tools weren't built for this.

Juggling Multiple Trackers

Most apps track one nutrient. CKD patients need to watch four. We unified them into a single dashboard.

Generic Limits Don't Fit

Your nephrologist says 2,000mg sodium. Generic apps say 2,300mg. We listen to your doctor, not population averages.

No Idea What's In Restaurant Food

We've analyzed 1,600+ dishes at 50+ chains — with sodium, potassium, and phosphorus estimates alongside oxalate.

How It Works

1

Set Your Condition

Tell us about your health. CKD? Dialysis? Post-bariatric? We set personalized nutrient limits based on clinical guidelines.

2

Log Your Food

Search 2,500+ foods, scan barcodes, or snap restaurant menus. We calculate all four nutrients instantly.

3

Watch Your Rings

Four concentric rings show your daily progress. Stay in the green. Your kidneys will thank you.

Built for People Who Need It Most

Different conditions, different limits. OxalateGuard adapts to your specific renal health needs.

CKD Stage 3-5

Your nephrologist said watch sodium and phosphorus. We track both — plus potassium and oxalate — with limits calibrated to your CKD stage.

Dialysis

Pre-dialysis nutrient management in your pocket. Know exactly what you're consuming between sessions so you arrive prepared.

Kidney Stone Formers

The oxalate tracker you know and love — now with the full renal picture. See how sodium and hydration affect your stone risk.

Heart Failure

Sodium restriction is critical. See exactly where you stand meal by meal, with a dashboard designed for daily limits.

Every Food, Four Nutrients

Search any food and see oxalate, sodium, potassium, and phosphorus at a glance. Nutrient pills show exactly how much each food contributes to your daily limits. No more guessing, no more separate lookups.

  • Color-coded nutrient pills for quick scanning
  • Daily impact percentages based on your personal limits
  • One-tap logging to your daily tracker

Frequently Asked Questions

What nutrients does OxalateGuard track?
Oxalate, sodium, potassium, and phosphorus. Oxalate tracking is free for all users. Sodium, potassium, and phosphorus tracking is available with a premium subscription.
Are the nutrient limits personalized?
Yes. When you tell us your health conditions during onboarding, we set nutrient limits recommended for your specific situation. CKD stage 3-5 gets different limits than someone with kidney stones alone. You can also set custom limits based on your doctor's recommendations.
Where does the nutrient data come from?
Our oxalate data comes from 15+ peer-reviewed sources including Harvard and Wake Forest. Sodium, potassium, and phosphorus data comes from the USDA FoodData Central database, matched to our 2,500+ food entries.
Can I use this for dialysis diet management?
Yes. While we don't replace your dietitian, we help you track the nutrients that matter between sessions. Set your own custom limits or use our condition-aware defaults for dialysis patients.
Is the free version useful for CKD patients?
Absolutely. Free users get full oxalate tracking, food database access, and barcode scanning. Premium unlocks sodium, potassium, and phosphorus tracking with the 4-ring dashboard.
Can my doctor recommend this to patients?
Yes. OxalateGuard is designed to complement clinical care, not replace it. Our data is sourced from peer-reviewed research and USDA databases. Contact us for information about recommending OxalateGuard to your patients.
