Why Calcium Counts for Adults

Calcium is the most abundant mineral in your body. You need it every day for muscle contraction, blood clotting and nerve function. When your body doesn't get enough calcium, it takes the required amount from your bones, which weakens them. This process becomes more damaging during the menopausal years when estrogen drops.

But you're never too young to pay attention to your calcium needs. A healthy diet including enough calcium (and vitamin D to help optimize its absorption), boosted by weight-bearing physical activity every day, may help reduce the risk of later osteoporosis.*

Still: no matter how good your diet is, many adults have inadequate intakes of calcium and vitamin D.** Nearly 80% of Canadian women under 50 years old do not consume the recommended amount of calcium to help maintain healthy bone structure and, therefore, could benefit from calcium supplements. And the need for supplements increases after age 40. Take a look at this chart:

How Much Calcium Do I Need?

Adults 19-50: 1,000 mg/day

Men, 51-70: 1,000 mg/day***

And 600 international units (IUs) of vitamin D per day

**Osteoporosis Canada recommends 1,200 mg/day
