About Calcium + Phosphate

Calcium alone ≠ bone
Calcium + Phosphate = bone mineral

Bone mineral naturally contains both calcium and phosphate. EncaptiCal™ TCP supplies both ions in one mineral source, helping brands build bone-health formulas around the same calcium-phosphate chemistry found in bone.

About Microencapsulation

Standard tricalcium phosphate offers strong mineral density, but it can be difficult to disperse and may deliver limited calcium bioaccessibility. EncaptiCal™ surrounds TCP with a sunflower lecithin-based matrix designed to improve wetting, dispersion, processing stability, and interaction with the digestive environment.

The result is a high-loading calcium ingredient with stronger preclinical absorption data and broader application potential across tablets, capsules, and powder sachets.

A microencapsulated TCP delivering 36% calcium with stronger preclinical serum calcium exposure than benchmark encapsulated and non-encapsulated TCP.

EncaptiCal™ demonstrated significantly higher calcium exposure compared to both benchmark encapsulated TCP group (**, p<0.01; ***, p<0.001, t-test) and the TCP group (###, p<0.001, t-test), while no significant difference was observed between the two control groups.
