Enhancing Bio-Availability of Vitamin D by Nano-Engineered Based Delivery Systems- An Overview

These functional foods designed to provide health benefits beyond basic nutrition (KayaCeliker and Mallikarjunan, 2012). Accruing evidences have acclaimed that dietary consumption of vitamin D is linked with low risks of multiple chronic diseases (Calvo et al., 2013; Green et al., 2010; Hohman et al., 2011; Jasinghe et al., 2005; Keane et al., 1998; Keegan et al., 2013; Ko et al., 2008; Koyyalamudi et al., 2009; Lehtonen-Veromaa et al., 2008; Natri et al., 2006; Outila et al., 1999; Stephensen et al., 2012; Urbain et al., 2011). Nevertheless, vitamin D has poor bioavailability, which significantly reduces its efficacy as disease-combating agents (Holick 2004; Hollander et al., 1978).
