The Calcium chronicles: How much do you really need? Try calcium Calculator

As one of the building blocks of our body, calcium plays a key role in maintaining the strength and structure of our bones and teeth. This crucial mineral makes up about 1kg of our body weight, and a staggering 99% of it is stored in our bones. But how much calcium do we really need and how can we ensure we're meeting our daily requirements?

The Recommended Daily Allowance (RDA) of calcium varies depending on age, gender and life stage. Here are some general guidelines from the UK’s National Health Service (NHS):

  • Infants 0-12 months: 525 mg/day
  • Children 1-3 years: 350 mg/day
  • Children 4-6 years: 450 mg/day
  • Children 7-10 years: 550 mg/day
  • Adolescents 11-18 years (Boys): 1000 mg/day
  • Adolescents 11-18 years (Girls): 800 mg/day
  • Adults 19-64 years: 700 mg/day
  • Adults 65+ years: 1200 mg/day
  • Pregnant and breastfeeding women: 700 mg/day

The key to meeting your calcium needs is diversity in your diet. Incorporating a variety of calcium-rich foods can help ensure you’re getting the right amount of calcium each day.

If you’re concerned about your calcium intake or if you’re at risk for osteoporosis, it’s always a good idea to consult a healthcare professional or a dietitian for personalized advice.
