Why is Calcium Important?

Did you know that we only build bone during the first 30 years of our life? In fact, most of us stop building it around the age of 25. After this our bone density stabilizes until we turn 40 or so where it begins to decline which weakens the bone and  increases the risk of osteoporosis, falls, broken bones etc. Therefore calcium is needed in the early stages of life to build up bone density so that we are prepared for it to decline in our forties allowing us to minimize the loss.

Are you getting enough Calcium every day?

The daily requirements differ according to gender, age and lifestyle factors but as a general guide the following amounts should be sufficient:

0-10   years 350-550mg/day
11-18 years 800-1000mg/day
> 20 years 700mg/day


There will be many occasions where someone might need more calcium than what is stated above such as when someone is coeliac, breastfeeding or following a vegan diet. Food is the best source of all nutrients however supplementation may be necessary for:  the elderly and the housebound, people on a restricted diet, people with a raised calcium requirement or when little exposure to the sunlight is indicated. Vitamin D is necessary for effective calcium absorption from the gut.

Where do you get your calcium?
