Did you know there is multiple types of calcium? so when you get encouraged to take so many mg of calcium do your research on the actual calcium that states on the ingredient of the product and what your body is actually absorbing... here is some examples
Common Types of Calcium Supplements
Calcium Carbonate
Contains about 40% elemental calcium.
Best absorbed when taken with food because it requires stomach acid for optimal absorption.
Often inexpensive and widely available in tablets, chewables, and fortified foods.
May cause bloating or constipation in some individuals.
Calcium Citrate
Contains about 21% elemental calcium.
Absorbed well on an empty stomach and suitable for people with low stomach acid or those taking acid-reducing medications.
Less likely to cause gastrointestinal discomfort.
Often recommended for adults over 50 or those with digestive issues.
Calcium Gluconate
Contains about 9% elemental calcium.
Lower calcium content, so higher doses may be needed to meet daily requirements.
Calcium Lactate
Contains about 13% elemental calcium.
Gentle on the stomach and sometimes used in individuals sensitive to higher doses of calcium
Calcium Phosphate
Includes forms like tricalcium phosphate and microcrystalline hydroxyapatite (MCHC).
Found naturally in milk and teeth; supports bone and dental health.
Absorption is generally good, and it may provide additional phosphate for bone structure
Calcium Malate
Calcium bound with malic acid.
Well absorbed and may be gentler on the digestive system.
Often used in combination supplements for bone
Calcium Sulfate
Less common, sometimes used in fortified foods or specialty supplements.
Provides moderate elemental calcium and is generally well tolerated
