Mineral

Calcium

Approximately 99% of the body's calcium is stored in bones and teeth. The remaining amount supports tightly regulated functions in blood, muscles and nerves.

Adequate calcium intake helps maintain normal bone structure, muscle function, nerve transmission and blood clotting.

In everyday life, Calcium helps maintain the strong skeletal framework, coordinated muscle movement and steady nerve signalling you rely on every day.

The elemental mineral amount is more meaningful than the weight of its source compound.

Ingredient overview

What it is

Approximately 99% of the body's calcium is stored in bones and teeth. The remaining amount supports tightly regulated functions in blood, muscles and nerves.

  • Scientific identity: Calcium; body distribution: approximately 99% skeletal hydroxyapatite.
  • How it works: Supplied as a compound: Calcium is never taken as a bare metal - each form differs in elemental content and in how much it depends on stomach acid. Absorbed in the small intestine: Uptake is active and vitamin D dependent at ordinary intakes, and passive at higher ones.
  • Primary function: Adequate calcium intake helps maintain normal bone structure, muscle function, nerve transmission and blood clotting.
  • What it supports: Calcium helps maintain the strong skeletal framework, coordinated muscle movement and steady nerve signalling you rely on every day.
  • Important consideration: The elemental mineral amount is more meaningful than the weight of its source compound.

Formulation rationale

Why we use it

CARPEDIEM selected Calcium for a clearly defined role within a thoughtfully balanced formulation.

  • Formulation purpose: Adequate calcium intake helps maintain normal bone structure, muscle function, nerve transmission and blood clotting.
  • Used in: CARPEDIEM MultiTeen and CARPEDIEM Whole Family Wellness Pack.
  • Works alongside: Calcium complements Vitamin D3 and Magnesium to support balanced daily mineral nutrition.
  • Meaningful contribution: Calcium helps maintain the strong skeletal framework, coordinated muscle movement and steady nerve signalling you rely on every day. Contributes to nerve signalling that helps muscles respond to everyday demands.
  • Quality and scientific context: The elemental mineral amount is more meaningful than the weight of its source compound. 2 ingredient-specific studies are included because the research reports a relevant benefit.

Ingredient intelligence

How it works

The body's most abundant mineral, and how the skeleton doubles as its store.

Step 01 / 04

Always a compound.

Calcium is never taken as pure metal. Each salt differs in how much elemental calcium it holds and how easily it dissolves.

01 / 04

Distribution

~99 per cent in bone and teeth

Needs

Vitamin D to absorb efficiently

Absorption ceiling

About 500 mg per dose

Controlled by

Parathyroid hormone and vitamin D
