Abstract

Background: vitamin D (25(OH)D) is a fat-soluble vitamin that is unstable in the gastrointestinal environment and has low bioavailability. A protein-lipid complex (liprotide) can be used as a shell to increase vitamin D stability and bioavailability. Liprotide can also serve as a delivery system for transporting vitamin D to its intended site. Little attention has been paid to utilizing liprotide as a delivery system for vitamin D and evaluating its functional activity.Objective: to investigate the effect of liprotide-encapsulated vitamin D3 on PTH levels and bone microstructure in vitamin D and calcium (VD-Ca) deficient rats.Materials and Methods: an overall of 24 Wistar rats had been divided into four groups, a normal control group (K), a VD-Ca group without treatment (K-), a VD-Ca group with 180 IU/200 gBW/day free vitamin D3 (FVD3), and a VD-Ca group with 180 IU/200 gBW/day liprotide-encapsulated vitamin D3 (LVD3). Before and after 28 days of vitamin D intervention, blood samples were taken and analysed for serum PTH levels. The microstructure of the bone was analyzed using the Scanning Electron Microscope (SEM).Results: the VD-Ca rats supplemented with vitamin D3 (FVD3 and LVD3) had a significant decrease in serum PTH levels (p<0.001) and improved bone microstructure (p<0.05) compared to the (K-) group. The reduction of PTH in the LVD3 group was higher compared to the FVD3 group. The bone microstructure between the FVD3 and LVD3 groups is significantly different, as seen in the Ct.Wi parameter, with the LVD3 group having a higher Ct.Wi than the FVD3 group.Conclusion: liprotide-encapsulated vitamin D3 improves the serum PTH level and bone microstructure in a rat model of vitamin D and calcium deficiency.

Abstract

Over the past five decades, the increasing incidence of obesity has sparked considerable interest in nutraceuticals as promising natural alternatives for effective weight management and metabolic health improvement. Sulforaphane (SFN), an isothiocyanate abundant in cruciferous vegetables, has gained attention for its potential in obesity management, particularly by promoting the browning of white adipose tissue (WAT) and transforming it into energy-burning fat. While its potential is significant, the underlying molecular mechanisms are complex and require a comprehensive synthesis. Therefore, this review explores sulforaphane (SFN) as a potential nutraceutical alternative by examining the scientific evidence of its anti obesity effects, focusing on its ability to activate multiple signalling pathways, including Nuclear Factor Erythroid 2-related factor 2 (Nrf2), AMP-activated protein kinase (AMPK), and sirtuin 1 (SIRT1), as well as upregulation of uncoupling protein 1 (UCP1). These are the key pathways in mitochondrial biogenesis, lipid metabolism, and thermogenesis. Additionally, SFN can mitigate oxidative stress and modulate inflammatory responses, further contributing to improved metabolic function and energy expenditure. While much of the research on SFN has focused on its effects on mature cruciferous vegetables, current research increasingly directs attention to microgreens, which contain significantly higher concentrations of bioactive compounds, including SFN. This review highlights SFN’s molecular mechanisms underlying its role in the context of obesity, specifically its effects on WAT browning, metabolic regulation, and thermogenesis. We also explored the potential of microgreen-derived SFN as a promising nutraceutical for obesity intervention and metabolic regulation, highlighting the novel bioactive chemical and biological properties of these plants.
