Too much of a Good Thing Part 2

CALCIUM
Hypocalcaemia is the term used to describe too much calcium.
The more serious problems that can occur from hypcalcaemia include:
Ø depression
Ø dehydration
Ø kidney stones
Ø bone fractures
Ø sudden heart attacks
Ø calcifications [hardening] of the heart, lungs, and joints

In a less severe situation, excess calcium can cause:
Ø abdominal pain, nausea, vomiting
Ø constipation
Ø fatigue
Ø weakness
Ø excessive thirst and passing of water

The upper limit for calcium intake is 2000mg/day, or about 200% daily value.
Those at risk for exceeding this are typically ones who supplement a diet already risk in calcium. It’s a good idea to check any products, especially nutrition bars, you might eat, since these are often fortified with 10-50% daily value of calcium. It’s also a good idea to refrain from taking a calcium supplement if you already eat dairy and fortified products in your diet.
