M.C.H.A. - Calcium Microcrystalline Hydroxyapatite

Microcrystalline Hydroxyapatite Calcium (MCHA)
The Gold Standard in Bioavailable Bone Support
100% of the calcium in our MCHA comes from real Australian pasture-raised bovine bone, not calcium carbonate, limestone, oyster shell, or synthetic isolates.
This is true bone nutrition in its most bioavailable and species-appropriate form, naturally containing calcium, phosphorus, collagen proteins, amino acids, and trace minerals in the same matrix found in raw bone.
NEW VERIFIED CALCIUM VALUES (CURRENT CERTIFICATE OF ANALYSIS)
Each 455g bag contains approximately 106,800mg of elemental calcium.
This is based on the most recent independent laboratory analysis showing:
• Calcium: 23.47%
• Phosphorus: 11.98%
• Protein: 29.82%
This equals approximately 235mg calcium per gram of MCHA powder.
The natural calcium-to-phosphorus ratio is approximately 2:1, closely matching real raw bone.
How to Use MCHA to Balance Raw Muscle and Organ Grinds (No Bone)
For those feeding boneless muscle meat and organ blends, MCHA can be used to provide the mineral profile of approximately 10% raw bone.
The Math
• Approximately 195mg calcium is required per ounce of boneless muscle and organ food
• A 16oz (1 lb) portion requires approximately 3,125mg calcium
• MCHA provides approximately 235mg calcium per gram
3,125mg ÷ 235mg = 13.3g MCHA
Recommended Use
We recommend using approximately 13 to 13.5g MCHA per pound of boneless muscle meat and organs.
This provides the calcium equivalent of approximately 10% raw bone while maintaining an appropriate calcium-to-phosphorus balance.
Result
One 455g bag will balance approximately 34 pounds of boneless muscle and organ food at the 10% bone equivalent level.
What Makes MCHA Superior?
• Derived from Australian pasture-raised bovine bone
• Freeze-dried and minimally processed
• Never subjected to high-heat rendering
• Provides naturally occurring calcium and phosphorus in the same ratio found in raw bone
• Contains collagen proteins and amino acids including glycine, proline, and hydroxyproline
• Rich in naturally occurring bone growth factors
• Supports connective tissue, skeletal integrity, and healthy mineral metabolism
• Naturally contains phosphorus unlike eggshell calcium
• Suitable for puppies, adults, seniors, pregnant, and nursing dogs
• Extremely low heavy metal levels verified by independent laboratory testing
Unlike calcium carbonate and many synthetic calcium products, MCHA delivers the entire bone matrix, not just isolated calcium.
Why Not Eggshell?
Eggshell is primarily calcium carbonate and contributes virtually no phosphorus.
Dogs require both calcium and phosphorus in proper balance.
The current laboratory analysis of our MCHA shows:
• Calcium: 23.47%
• Phosphorus: 11.98%
This creates a calcium-to-phosphorus ratio of approximately 1.96:1, nearly identical to the ratio found in natural raw bone.
MCHA also supplies additional nutrients absent from eggshell, including amino acids, collagen proteins, and naturally occurring bone factors.
For this reason, MCHA is appropriate for growing puppies, breeding dogs, pregnant and nursing females, seniors, and dogs consuming boneless raw diets.
For Pregnant and Nursing Dogs
Late Gestation (Weeks 6-9)
Add approximately 13 to 13.5g MCHA per pound of boneless muscle and organ food.
MCHA supports:
• Fetal skeletal development
• Maternal mineral reserves
• Healthy uterine function
• Proper calcium metabolism
Labor Support
For females entering labor or experiencing weak contractions:
• Offer a pinch to 1/8 teaspoon mixed with honey, broth, or goat milk
• Can be licked from a spoon or administered via syringe
• Allow the dam to self-regulate intake when offered calmly
Storage
• Store in a cool, dry location
• Keep away from excessive moisture and direct sunlight
• Shelf life up to 3 years when properly stored
• Each package includes storage and usage instructions
Transparency Matters
Every batch is accompanied by a Certificate of Analysis and manufacturer documentation.
Current verified laboratory analysis:
