WOMEN need a higher daily calcium intake than currently recommended by the Government to prevent bone loss and osteoporosis, a leading charity has warned. The daily amount recommended for adults is currently 700mg but research from New Zealand and France, published in the New England Journal of Medicine, suggests that post-menopausal women need 1,000mg. The National Osteoporosis Society is now advising a daily intake of 1,500mg for women over 45 and 1,000mg for those on HRT.
