The aim of this research study is to determine by laboratory analyses the effects of drinking silicon-rich water on bone health. This will be determined from blood and urine samples from subjects who will be asked to drink 1 liter per day of either silicon-rich water or water without silicon for 12 weeks.

Further study details as provided by University of California, Los Angeles:

Primary Outcome Measures:
  • To measure changes in 12 weeks of biomarkers of bone formation and bone resorption, blood levels of 25 hydroxyvitamin D, parathyroid hormone (PTH), calcium, and urinary silicon. [ Time Frame: 12 Weeks ]

Secondary Outcome Measures:
  • To assess whether the silicon in Fiji water increases bone formation parameters and/or reduces the bone resorption parameter, thus suggesting a benefit in bone health. [ Time Frame: 12 Weeks ]

Enrollment: 15
Study Start Date: June 2007
Study Completion Date: February 2011
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Fiji Water
Participants are asked to consume one liter of this silicon-rich water daily for three months.
Other: Fiji Water
Participants are asked to drink one liter of this silicon-rich water daily for three months.
No Intervention: Aquafina Water
Participants are asked to drink one liter of this deionized water daily for three months.


Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Body mass index (BMI) < 30
  • Postmenopausal women with no evidence of osteoporosis by dual energy X-ray absorptiometry (DEXA) scan (T ≥ -2 in the total hip and lumbar spine).
  • Pre- or peri-menopausal women with osteopenia but no evidence of osteoporosis by DEXA scan (−1.5 ≤ T ≤ −2 in the total hip and lumbar spine)
  • No estrogens or corticosteroids
  • No prior history of bisphosphonate medication
  • Otherwise in good health with no significant illnesses which could affect bone metabolism such as hypercortisolism, untreated hypothyroidism, treatment with statins or other drugs affecting bone metabolism other than calcium and vitamin D3.
  • No change in exercise regimen or calcium intake in the past 3 months.
  • Subject must sign the Institutional Review Board-approved written informed consent prior to the initiation of any study specific procedures or randomization. A subject will be excluded for any condition that might compromise the ability to give truly informed consent for participation in the study.

Exclusion Criteria:

  • Males
  • Premenopausal women with DEXA T scores ≥ -1.5 or ≤ -2.
  • Postmenopausal women with DEXA T scores ≤ -2.
