BioStacksCalcium and dental
For dental support, Calcium is a key ingredient backed by research. Essential for bone structure, muscle contraction, nerve signaling, and blood clotting. Calcium citrate is better absorbed than calcium carbonate and can be taken without food, while carbonate requires stomach acid and should be taken with meals.
Effective dosing
Most evidence supports 200–600 mg of calcium daily. Supplemental range; absorption drops sharply above 500mg/dose. Most adults get 700-900mg from food. Products below this range may not deliver meaningful results.
Form and bioavailability
Avoid calcium carbonate — requires stomach acid to absorb. Look for calcium citrate for better absorption.
What the research says
The clinical evidence for calcium in dental is strong. Large trials confirm bone density benefits; absorption drops above 500mg/dose, best paired with vitamin D and K2 Learn more
