Study summary

It was a prospective randomized controlled trial. A sample of 115 apparently healthy post-menopausal women(45 -75 years of age) randomized into four groups and received supplements of Ca, Vitamin D and Mg with or without enriched olive paste and with or without Vitamin C. Changes in calciregulatory hormone were evaluated at the beginning of the study, at 5 and 12 months . Blood levels of vitamin D, vitamin C, Ca, Mg, the lipid profile, anthropometric indices and bone density were assessed at the beginning and at the end of the study.

Read the detailed description

: It was a prospective randomized controlled trial. A sample of 115 apparently healthy post-menopausal women(45 -75 years of age) randomized into four groups: (I) nutritional intervention group(n=40) received daily 1000mg vitamin C, 500mg vitamin D3, 500mg calcium(Ca) and 300mg magnesium (Mg); (II) control group(n=42) received daily 500mg vitamin D3, 500mg Ca and 300mg Mg; (III) nutritional intervention group (n=18) received daily 150mg bisphosphonates, 500mg vitamin D3, 500mg Ca and 300mg Mg; and (IV) nutritional intervention group (n=15) received daily about 364 mg polyphenols via an innovative functional food (50g olive paste enriched with mountain tea extract) along with 500mg vitamin D3, 500mg Ca and 300mg Mg. Groups I -III received supplementation for a year whereas group IV for 5 months. Changes in calciregulatory hormone parathormone (PTH) were evaluated at the beginning of the study as well as at 5 and 12 months intervals. Blood levels of vitamin D, vitamin C, Ca, Mg and the lipid profile were assessed at the beginning and at the end of the study. Anthropometric indices (weight, body fat(Kg), Body Mass Index(BMI) and bone mineral density(BMD) were evaluated at the beginning and at the end of the study.
