If you are managing CKD, your doctor has probably told you to watch your sodium, potassium, and phosphorus. But tracking four nutrients across every meal? That has been nearly impossible -- until now.
Today we are launching multi-nutrient tracking in OxalateGuard. The same app you already use to monitor oxalate now tracks sodium, potassium, and phosphorus -- the four nutrients that define a renal diet. One dashboard, one food log, one place to see how your day is shaping up before your next meal.
What's New: The Four-Ring Dashboard
The centerpiece of this update is a new daily dashboard built around four concentric rings, each representing a nutrient that matters for your kidneys.
The new OxalateGuard dashboard showing four concentric rings. The outer sage-green ring tracks oxalate at 128 mg of your 200 mg daily budget. Inside, amber tracks phosphorus (450 mg/1,000 mg), blue tracks potassium (1,430 mg/2,600 mg), and coral tracks sodium (820 mg/2,000 mg). Below the rings, each nutrient shows its current intake versus your personalized limit.
At a glance, you can see where you stand on every nutrient. A ring that is nearly full tells you to choose carefully for your next meal. A ring with plenty of room means you have flexibility. No mental math, no spreadsheet -- just a visual answer to "how am I doing today?"
Oxalate tracking remains completely free, just as it has always been. The three new renal nutrients -- sodium, potassium, and phosphorus -- are available with OxalateGuard Premium.
Personalized to Your Condition
Not every kidney patient has the same limits. A CKD Stage 4 patient managing hyperkalemia has different targets than a recurrent stone former who just wants to keep oxalate in check. That is why the new dashboard is condition-aware.
When you set up multi-nutrient tracking, you tell us your situation, and we configure limits that match:
CKD Stage 3-5: The dashboard defaults to the guidelines your nephrologist likely follows -- sodium under 2,000 mg, potassium under 2,000 mg, and phosphorus under 800 mg per day. These align with KDOQI and KDIGO recommendations for moderate to advanced kidney disease.
Dialysis patients: If you are on hemodialysis or peritoneal dialysis, your between-session limits matter most. The dashboard supports customizable pre-dialysis targets so you can track the nutrients that fluctuate between treatments. Work with your care team to dial in the right numbers.
Kidney stone formers: If your primary concern is calcium oxalate stones, the oxalate ring is still front and center. The additional nutrient rings are optional -- turn them on if your urologist has recommended sodium restriction (which most do, since high sodium increases urinary calcium).
Post-bariatric surgery patients: Bariatric patients face a unique combination of risks including enteric hyperoxaluria, sodium sensitivity, and phosphorus depletion. The dashboard lets you set asymmetric targets -- tracking sodium to stay under a limit while tracking phosphorus to make sure you are getting enough.
Every limit is adjustable. Your nephrologist says potassium under 2,600 mg instead of 2,000 mg? Change it in settings. Your dietitian wants phosphorus under 1,000 mg? Done. The dashboard adapts to your prescription, not the other way around.
It Works Everywhere You Already Use OxalateGuard
We did not build a separate app for renal tracking. We added nutrient data to every feature you already know:
Food search. Every food in our database of 2,500+ foods now shows sodium, potassium, and phosphorus alongside oxalate. Search for "chicken breast" and you will see all four values with risk-coded badges, so you can make a decision in seconds.
Barcode scanner. Scan a packaged product at the grocery store with our barcode scanner, and the results now include all four nutrients pulled from the product's nutrition label. No more flipping the box around to check three different lines.
Menu Check. Snap a photo of a restaurant menu with Menu Check, and the AI analysis now estimates sodium, potassium, and phosphorus alongside oxalate for every dish. This is especially valuable for sodium, which restaurants are notorious for overusing.
50+ restaurant chains. Our pre-analyzed restaurant database -- Olive Garden, Applebee's, Chili's, Outback, and dozens more -- now includes full nutrient profiles for every cached dish. Browse them at /restaurants.
The experience is seamless. You do not need to learn a new workflow. Every scan, search, and log entry now captures the full picture automatically.
Where the Data Comes From
We take data sourcing seriously, and multi-nutrient tracking is no exception.
Oxalate data comes from 15+ peer-reviewed sources including Harvard, Wake Forest, Oxalate.org, MDPI, Avila-Nava 2021, and dozens of individual studies. We show every source on every food page so you can evaluate the evidence yourself.
Sodium, potassium, and phosphorus data comes from the USDA FoodData Central database, the gold standard for nutrient composition in the United States. We have matched USDA nutrient profiles to all 2,500+ foods in our database, cross-referencing by food name, category, and preparation method.
For packaged products scanned via barcode, nutrient values come directly from the product's nutrition facts panel through Open Food Facts, the same source we use for ingredient analysis.
Our methodology is transparent. We show our sources on every food detail page because we believe you should be able to verify the numbers your health decisions depend on. For a deeper look at how we handle data, see our food database methodology.
Who This Is For
Kidney disease is not rare. According to the CDC, approximately 37 million Americans have chronic kidney disease, and most do not know it until they reach an advanced stage. For those who do know, dietary management is one of the most powerful tools available -- and one of the hardest to execute consistently.
This update is built for:
CKD patients (Stages 1-5) who need to manage phosphorus and sodium to slow disease progression and protect their bones and cardiovascular system. For a detailed look at how phosphorus and oxalate interact, see our dual restriction guide.
Dialysis patients managing fluid, sodium, potassium, and phosphorus between sessions. The stakes are highest here -- a single high-potassium meal can cause dangerous cardiac arrhythmias. Having a tracker that shows your running total in real time is not a convenience; it is a safety tool.
Heart failure patients on strict sodium restriction. Many heart failure patients overlap with CKD, and sodium is the nutrient their cardiologist emphasizes most. Tracking sodium alongside other nutrients gives them the full picture.
Post-bariatric surgery patients dealing with the nutritional aftermath of malabsorptive procedures. These patients face elevated oxalate risk alongside sodium sensitivity and potential mineral deficiencies.
Kidney stone formers whose urologists have recommended dietary changes beyond just "drink more water." High sodium intake directly increases urinary calcium, which increases stone risk. Tracking sodium alongside oxalate addresses both sides of the calcium oxalate equation.
Anyone whose nephrologist, urologist, or dietitian has said "watch your diet" -- and who then had to figure out what that actually means in practice, three times a day, every day.
Getting Started
Getting started takes less than a minute:
Sign up free at oxalateguard.com. Oxalate tracking is always free, no credit card required.

That is it. No separate app, no data entry, no manual calculations. The same tools you already use, now tracking everything that matters.
Your Kidneys Don't Care About Just One Nutrient
For too long, kidney diet management has been fragmented. Your nephrologist says watch phosphorus. Your urologist says watch oxalate. Your cardiologist says watch sodium. And you are left trying to juggle three different lists, three different apps, and three different mental models of what "safe" looks like.
Now your tracker does not care about just one nutrient either.
OxalateGuard started because our founder had two kidney stones, two surgeries, and a dietitian who had to Google "oxalates." We built the oxalate tracker we wished existed. Now we have built the renal diet companion we wish had existed even earlier -- one dashboard that shows the full picture so you can eat with confidence instead of fear.
