Pouring Marah-Cel liquid onto a 5 mL spoon

The body doesn’t run on milligrams. It runs on ions.

SAC® is an ion-release calcium technology, built to deliver calcium in the form physiology actually uses, and backed by published human and preclinical research.

The Calcium Paradox

Calcium is abundant.
Available calcium is not.

99%of calcium stored in bone and teeth
The body’s mineral reserve
<1%~1% circulates and runs nerves, muscle, heart and cell signaling

At any moment, an adult’s blood holds only about 250 mg of ionized calcium (Ca2+), the fraction that helps nerves signal, muscles contract, and cells regulate. Calcium carbonate is a stable, poorly soluble solid, so conventional supplements compensate with 500 mg+ doses that depend on stomach acid and vitamin D–regulated transport.

How SAC® Works

From Calcium to Cellular Function

1

WEAKER
BOND

SAC® holds calcium less tightly

2

ION
AVAILABILITY

Designed to make free calcium ions available in solution

3

ABSORPTION

Passive (paracellular) as well as active routes

4

CELLULAR
FUNCTION

Homeostasis, signaling, bone remodeling

~200×

Higher ionization potential than regular calcium carbonate

Based on reported solubility-product (Ksp) values. A chemistry measure, not a human absorption multiple.

5–8 mg

SAC® per 5 mL serving, dosed to the scale of the ionized pool, not the skeleton

One serving adds roughly 2–3% to circulating Ca2+, well within normal range.

Conventional CaCO3 SAC®
Typical serving 500–600 mg calcium 5–8 mg SAC®
Primary focus Quantity of elemental calcium supplied Calcium-ion (Ca2+) availability
Absorption Mainly active, vitamin D–regulated Passive and active routes
Format Tablet or capsule Pre-dissolved liquid

Vitamin D remains essential to overall calcium balance and bone health.
