Plain English Summary

Background and study aims
Previous clinical studies have shown the anti-inflammatory and antioxidant characteristics of calcium fructoborate and suggest that this compound supports cardiovascular (heart) health. In particular, calcium fructoborate has been shown to lower CRP in patients with symptoms of osteoarthritis and stable angina pectoris. Further research suggests calcium fructoborate may lower blood levels of LDL-cholesterol and raise blood levels of HDL-cholesterol. The aim of our study is to assess the effects of FruiteX-B® Calcium Fructoborate on markers of subclinical atherosclerosis in a healthy population.

Who can participate?
This trial will include healthy men and women, age 40-60.

What does the study involve?
The study will take 30 days and participants will be randomly divided into two groups: one group will receive FruiteX-B® Calcium Fructoborate and the other group will be given a placebo (dummy drug). At the end of the study, we will compare the results of the blood clinical laboratory tests between the groups of participants.

What are the possible benefits and risks of participating?
The immediate benefit may be the reduction of inflammation and lipid markers. In the long term, the participants’ quality of life may be improved. There are no known risks of the study.

Where is the study run from?
Natural Research, Ltd. and the University of Medicine and Pharmacy, Craiova, Romania.

When is the study starting and how long is it expected to run for?
It is anticipated that recruitment will start mid 2012 and the trial will last for about 6 months.

Who is funding the study?
Natural Research, Ltd. and the University of Medicine and Pharmacy, Craiova, Romania.
