RESUMO

The paper describes a new, simple, selective and precise high-performance thin-layer chromatographic (HPTLC) method for the simultaneous identification and quantitative determination of boric acid (BA) and calcium fructoborate (CFB) in bulk and tablet/capsule dosage forms of dietary supplements. HPTLC silica gel G 60 F254 precoated glass plates were used as the stationary phase. The mobile phase consisted of 2-propanol-water 8:2 (v/v). The two boron-based compounds were adequately separated with the Rf values of 0.83 ± 0.01 (BA) and 0.59 ± 0.01 (CFB).

RESUMO

Calcium fructoborate (CF), a natural sugar-borate ester found in fresh fruits and vegetables, is a source of soluble boron. CF contains three forms of borate (diester, monoester, and boric acid) and all are biologically active, both at the intracellular (as free boric acid) and extracellular level (as fructose-borate diester and monoester). At the cellular and molecular level, CF is superior to the boric acid/borate, exhibiting a complex "protective" effect against inflammatory response. CF is commercially available in the USA as a "nature-identical" complex, an active compound for dietary supplements. It provides effective and safe support against the discomfort and lack of flexibility associated with osteoarticular conditions (arthritis and joint degeneration), and improves Western Ontario and McMaster Universities Osteoarthritis (WOMAC) and McGill indexes. In addition, orally administered CF is effective in ameliorating symptoms of physiological response to stress, including inflammation of the mucous membranes, discomfort associated with osteoarthritis disorders, and bone loss, and also for supporting cardiovascular health. Clinical studies have exhibited the ability of CF to significantly modulate molecular markers associated with inflammatory mechanisms, mainly on the elevated serum levels of C-reactive protein (CRP).

RESUMO

Calcium fructoborate (CFB) has been reported as supporting healthy inflammatory response. In this study, we assess the effects of CFB on blood parameters and proinflammatory cytokines in healthy subjects. This was a randomized, double-blinded, placebo-controlled trial. Participants received placebo or CFB at a dose of 112 mg/day (CFB-1) or 56 mg/day (CFB-2) for 30 days. Glucose, total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG), C-reactive protein (CRP), homocysteine, interleukin 1 beta (IL-1ß), IL-6, and monocyte chemoattractant protein-1 (MCP-1) were determined before and after supplementation. CFB-1 showed a reduction in blood levels of CRP by 31.3 % compared to baseline. CFB-1 and CFB-2 reduced LDL levels by 9.8 and 9.4 %, respectively. CFB-1 decreased blood homocysteine by 5.5 % compared with baseline, whereas CFB-2 did not have a significant effect. Blood levels of TG were reduced by 9.1 and 8.8 % for CFB-1 and CFB-2, respectively. Use of both CFB-1 and CFB-2 resulted in significantly reduced IL-6 levels, when compared within and between groups. IL-1ß was reduced by 29.2 % in the CFB-1 group. Finally, CFB-1 and CFB-2 reduced MCP-1 by 31 and 26 %, respectively. Our data indicate that 30-day supplementation with 112 mg/day CFB (CFB-1) resulted in a significant reduction of LDL, TG, TC, IL-1ß, IL-6, MCP-1, and CRP. HDL levels were increased, when compared to baseline and placebo. These results suggest that CFB might provide beneficial support to healthy cardiovascular systems by positively affecting these blood markers (ClinicalTrials.gov, ISRCTN90543844; May 24, 2012 ( http://www.controlled-trials.com/ISRCTN90543844 )).

RESUMO

Inflammation has been identified as a possible contributory factor to disruption of the normal bone remodeling process, a process essential to healthy bone mineral density. Several large population-based clinical studies have specifically shown that levels of C-reactive protein, an immune recognition protein that is a sensitive marker of inflammation, are inversely and independently associated with total bone mineral density. The evidence suggests that control of C-reactive protein levels may contribute to bone health by protecting against inflammation's disruption of the equilibrium between bone resorption and bone deposition. Calcium fructoborate, a patented complex of calcium, fructose, and boron found naturally in fresh and dried fruits, vegetables and herbs, and wine, is a sugar-borate ester. A growing body of peer-reviewed, published clinical research indicates that the calcium fructoborate significantly reduces serum levels of the C-reactive protein in humans, suggesting that this unique plant-mineral complex may contribute to bone health by controlling the inflammation associated with loss of bone mineral density.

RESUMO

OBJECTIVE: This study aimed to evaluate the effects of short-term (60-d) oral supplementation with calcium fructoborate, resveratrol, and their combination on the clinical and biological statuses of subjects with stable angina pectoris. METHODS: A randomized, double-blinded, active-controlled, parallel clinical trial was conducted in three groups of subjects. Of the total number of subjects included in study (n = 166), 87 completed the 60-d test treatment study period and 29 followed in parallel their usual medical care and treatment. The primary outcomes were inflammation biomarkers (high-sensitivity C-reactive protein), left ventricular function markers (N-terminal prohormone of brain natriuretic peptide), and lipid markers (total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triacylglycerols). Quality of life was assessed by the Canadian Cardiovascular Society angina class and the number of angina attacks per week. RESULTS: There was a significant decrease of high-sensitivity C-reactive protein in all groups at the 30-d and 60-d visits. This decrease was greater (39.7% at 60 d) for group 3 (calcium fructoborate), followed by group 2 (resveratrol plus calcium fructoborate, 30.3% at 60 d). The N-terminal prohormone of brain natriuretic peptide was significantly lowered by resveratrol (group 1, 59.7% at 60 d) and by calcium fructoborate (group 3, 52.6% at 60 d). However, their combination (group 2) was the most effective and induced a decrease of 65.5%. Lipid markers showed slight changes from baseline in all groups. The improvement in the quality of life was best observed for subjects who received the resveratrol and calcium fructoborate mixture (group 2). CONCLUSION: The results indicate that the combination of resveratrol and calcium fructoborate has beneficial effects in patients with angina
