Dicalcium Phosphate

A useful mineral adjustment, not a bone boost

Dicalcium phosphate is a manufactured mineral powder that supplies calcium and phosphorus together. It helps a complete food meet its mineral targets. Its place on the ingredient list does not reveal the finished food's calcium or phosphorus levels.

Role in the food Supporting nutrient
What it is
A feed mineral produced from a phosphorus source and calcium to supply both minerals in dog food.
Made from
Phosphate rock and calcium carbonate
Main job
Calcium and phosphorus adjustment

Watch for
Total phosphorus in dogs with kidney disease
Not the same as
Bone meal

Straight answer

Is Dicalcium Phosphate safe for dogs?

Check the finished food's mineral levels

Dicalcium phosphate low on the list is an ordinary mineral adjustment. Check the nutritional adequacy statement for your dog's life stage. If calcium or phosphorus matters for your dog, ask the maker for the finished food's levels. The ingredient's position cannot answer that question.

The story

A feed mineral shaped by fluoride and mad cow

One route to dicalcium phosphate starts with mined phosphate rock, the raw material feed phosphate plants turn into mineral salts for pigs and poultry. Raw rock cannot go straight into feed. A 1983 patent noted that Florida phosphate rock carries about 3.0 to 4.2% fluorine, too much for animal feed, so removing most of it became part of making feed phosphates. Dog food recipes use this same feed mineral to adjust calcium and phosphorus.3,7,14

A second route made dicalcium phosphate from animal bones, which put it inside the mad cow crisis. France banned meat and bone meal from cattle feed on July 30, 1990, but bone-derived dicalcium phosphate stayed legal for cattle until November 2000, when a total ban on meat and bone meal for farm animals took effect. A 2007 French analysis of feed use and BSE cases found no significant link to bone-derived dicalcium phosphate.12

Later research compared phosphate forms directly in dogs. In a 2021 trial, researchers fed 8 Beagles high phosphorus diets built on 8 different phosphate sources, each for 18 days. Blood phosphorus after a meal reached 3.1 mmol/L with soluble monosodium phosphate and 1.6 with dicalcium phosphate. Every test diet was deliberately high in phosphorus, and the study did not measure kidney damage.1

What it is

How it is made

Feed phosphate plants process mined rock into phosphorus compounds, then combine them with a calcium source. Dicalcium phosphate is made for animal feed; it is not a leftover from meat processing.7,11

  1. 01 // Source Phosphate rock Mined phosphate rock supplies the phosphorus used to make feed mineral salts.
  2. 02 // Process Release phosphorus Acid treatment releases phosphorus from the rock into phosphoric acid.
  3. 03 // Process Add calcium Phosphoric acid reacts with calcium carbonate, producing calcium phosphates that include dicalcium phosphate.
  4. 04 // Output Dry feed mineral The mineral is separated and dried before shipment to feed makers.

What is in it

Composition, dry matter

245

g/kg calcium

The average for dicalcium phosphate dihydrate. It supplies phosphorus too, so the finished food needs both mineral levels checked.

Calcium 230-311 g/kg5
Phosphorus 168-207 g/kg5
Ash 87.1-95.8%5
Crude protein 0%5

These ranges describe the hydrated form. The anhydrous form has higher average calcium and phosphorus concentrations. Commercial products also vary because manufacturing can leave different proportions of calcium phosphate forms.5,6,7

Why it is in the bag

A small scoop that sets calcium and phosphorus

  1. Main nutrition
  2. Supporting nutrient
  3. Does a job
  4. Mostly filler

Makers add it when the meats, grains and other ingredients leave calcium or phosphorus short of the targets a complete food must meet. Lists run by weight, so a small inclusion lands below the main ingredients, but it averages 245 g/kg calcium and 175 g/kg phosphorus on a dry matter basis. Five test kibbles used 0.87 to 2.33%, likely enough to shift the food's mineral levels. It adds no protein.3,5,8,9

  1. 01

    Adjusts two minerals

    Each addition raises calcium and phosphorus together. Formulators account for the minerals supplied by the other ingredients when setting the amount.5,10

  2. 02

    Meets recipe targets

    Complete dog foods must meet nutrient targets or pass a feeding trial. Dicalcium phosphate is one way to add minerals when a recipe needs them.8,10

  3. 03

    Fits feed production

    Feed phosphate plants produce mineral salts for animal diets at scale. A measured dry ingredient lets makers adjust minerals without replacing the recipe's main ingredients.7

How much Five experimental adult kibble formulas contained 0.87 to 2.33% dicalcium phosphate; that range is not a published typical amount.3

Our read // The claims

What the evidence supports

Strong: controlled studies in dogs agree. Some: small or mixed dog data. Thin: mechanism or lab work only. None: nothing, or the evidence points the other way.

  1. Brands say

    Supplies calcium and phosphorus together

    Evidence

    1. Strong
    2. Some
    3. Thin
    4. None

    The hydrated form averages 245 g/kg calcium and 175 g/kg phosphorus on a dry matter basis. The powder supplies both minerals, but its name cannot tell you the finished food's mineral levels.5,9

  2. Brands say

    Builds stronger bones and teeth

    Outruns the evidence

    Evidence

    1. Strong
    2. Some
    3. Thin
    4. None

    Calcium and phosphorus are required nutrients, and AAFCO sets minimums for growing dogs. Supplying a shortfall matters. That does not show that extra dicalcium phosphate strengthens bones or teeth in a dog already fed a complete diet.8,10

  3. Critics say

    Added dicalcium phosphate damages kidneys

    Outruns the evidence

    Evidence

    1. Strong
    2. Some
    3. Thin
    4. None

    In an 18-day trial with 8 healthy dogs, a high phosphorus diet containing dicalcium phosphate raised blood phosphorus after a meal. The researchers did not test kidney damage or the amounts used in ordinary kibble.1

  4. Brands say

    Its phosphorus is fully absorbed

    Outruns the evidence

    Evidence

    1. Strong
    2. Some
    3. Thin
    4. None

    The dicalcium phosphate diet had 20.5% apparent phosphorus digestibility in one dog trial. Another 8-dog comparison found 20% with the hydrated form, versus 26% with a soluble phosphorus source. Full absorption is unsupported.1,2

  5. Critics say

    It is just filler

    Outruns the evidence

    Evidence

    1. Strong
    2. Some
    3. Thin
    4. None

    The hydrated form averages 245 g/kg calcium and 175 g/kg phosphorus. It supplies no protein or fat, but experimental adult kibble formulas used it to adjust minerals. That is a specific nutritional job.3,5

The research

Studies worth knowing

Published research we read for this page, dog studies first.

  1. 2021 // Feeding trial, 8 phosphate sources

    Dicalcium phosphate raised blood phosphorus far less than soluble salts1

    8 healthy adult Beagles

    Found. Each high phosphorus diet was fed for 18 days. Blood phosphorus after a meal reached 1.6 mmol/L on dicalcium phosphate versus 3.1 on monosodium phosphate, and phosphorus digestibility was 20.5% versus 32.5%.

    What it means. The form of added phosphorus changes how much reaches the blood. Dicalcium phosphate is one of the milder forms, though every test diet was deliberately high in phosphorus.

  2. 2025 // Feeding trial, 2 diets

    Dogs absorbed less phosphorus from dicalcium phosphate than a soluble salt2

    8 adult Foxhound cross dogs

    Found. Apparent phosphorus digestibility of the whole diet was 20% with dicalcium phosphate dihydrate versus 26% with monosodium phosphate. Urine phosphorus before meals was also lower, 31.7 versus 47.7 mmol/L.

    What it means. Swapping a soluble salt for dicalcium phosphate lowered how much of the diet's phosphorus dogs absorbed. The figure covers the whole diet, not the mineral alone.

  3. 2002 // Feeding trial, 3 diets

    Puppy bone mineral followed diet calcium and phosphorus early on13

    32 Great Dane puppies from 4 litters

    Found. From weaning through 18 months, puppies ate 1 of 3 diets with calcium and phosphorus in a fixed ratio. Bone mineral rose with diet levels until 5 to 6 months, then hormones adjusted absorption and excretion.

    What it means. Mineral levels matter most in a giant breed puppy's first months. The study tested mineral amounts, not dicalcium phosphate as an ingredient.

Straight answers

What owners ask

  1. Q01

    Is it just filler?

    No

    It supplies calcium and phosphorus that a complete diet must account for. It has no protein or useful calories, but those are not its jobs. Judge the finished food's mineral levels.5,8,10

  2. Q02

    Is it the same as bone meal?

    No

    Bone meal comes from animal bone. Dicalcium phosphate is made through a mineral production process. Both contribute calcium and phosphorus, but they are different ingredients with different sources.1,7

  3. Q03

    What if my dog has kidney disease?

    Check phosphorus

    The finished diet's phosphorus level matters more than this ingredient's presence. In a trial of dogs with surgically reduced kidney function, those fed less phosphorus survived longer. Ask for the food's phosphorus level.4

  4. Q04

    Can the list show its amount?

    No

    Ingredients appear in descending order by weight, so placement offers only a rough clue. It cannot tell you the amount of dicalcium phosphate or the finished food's calcium and phosphorus levels.9
