Calcium Supplement

Supplement Overview

  • Inadequate calcium intake during adolescence and early adulthood may lead to sub-optimal bone status.
  • Calcium requirements elevated by growth in childhood and adolescence, pregnancy, and breastfeeding.
  • Increased calcium intake may be needed to ensure calcium balance in female athletes with impaired menstrual status (1500 mg/d).
  • At risk athletes:
    • Athletes with an inadequate energy intake, or inadequate intake of dairy and fortified soy products.
    • Female athletes with impaired menstrual function (i.e. failure to start menses, secondary amenorrhoea, menopause)

Supplement Profile

  • 600 mg/d
  • Only used under medical supervision as part of an integrated program for bone health.

Situations for Use in Sport

  • Individuals at risk of consuming an inadequate calcium intake or whom have elevated calcium requirements as determined by an AIS sports physician.

Concerns Associated with Supplement Use

  • Calcium supplementation does not guarantee bone status in absence of an adequate oestrogen/progesterone status. Athletes with impaired menstrual status should receive appropriate attention to hormonal status.
  • Athletes with disordered eating or eating disorders require significant treatment in addition to calcium supplementation.
