Calcium — 1.5%
Lends rigidity and strength to bones and teeth; also important for the functioning of nerves and muscles, and for blood clotting.
Phosphorus — 1.0%
Needed for building and maintaining bones and teeth; also found in the molecule ATP (adenosine triphosphate), which provides energy that drives chemical reactions in cells.
Potassium — 0.4%
Important for electrical signaling in nerves and maintaining the balance of water in the body.
Sulfur — 0.3%
Found in cartilage, insulin (the hormone that enables the body to use sugar), breast milk, proteins that play a role in the immune system, and keratin, a substance in skin, hair and nails.
Chlorine — 0.2%
Needed by nerves to function properly; also helps produce gastric juices.
Sodium — 0.2%
Plays a critical role in nerves’ electrical signaling; also helps regulate the amount of water in the body.
Magnesium — 0.1%
Plays an important role in the structure of the skeleton and muscles; also found in molecules that help enzymes use ATP to supply energy for chemical reactions in cells.
