ABSTRACT The goal of this study was to examine the effect of a standardized silybin and soy phosphatidylcholine complex (IdB 1016) on serum markers of iron status.
Milk thistle and its components are widely used as an alternative therapy for liver disease because of purported antioxidant, anti-inflammatory, and iron chelating properties.
Thirty-seven patients with chronic hepatitis C and Batts-Ludwig fibrosis stage II, III, or IV were randomized to 1 of 3 doses of IdB 1016 for 12 weeks. Serum ferritin, serum iron, total iron binding capacity, and transferrin-iron saturation were measured at baseline, during treatment, and 4 weeks thereafter. Wilcoxon signed rank tests were used to compare baseline and posttreatment values.
There was a significant decrease in serum ferritin from baseline to end of treatment (mean, 244 vs. 215 mug/L; median, 178 vs. 148 mug/L; P=0.0005); 78% of subjects had a decrease in serum ferritin level. There was no significant change in serum iron or transferrin-iron saturation. Multivariate logistic regression analysis in a model that included dose, age, sex, HFE genotype, history of alcohol use, and elevated baseline ferritin levels demonstrated that stage III or IV fibrosis was independently associated with decreased posttreatment serum ferritin level.
Treatment with IdB 1016 is associated with reduced body iron stores, especially among patients with advanced fibrosis stage.

A published study reported that the iron-chelating properties of silybin were responsible for a decrease in body iron stores in patients with chronic hepatitis C who had been taking silybin orally for 12 weeks (Bares et al., 2008), which supports the outcome of our study. Likewise, silybin in conjunction with desferrioxamine may be a more effective means of reducing iron stores in patients with β-thalassaemia, compared with desferrioxamine alone (Gharagozloo et al., 2009).

    ABSTRACT: Milk thistle contains silybin, which is a potential iron chelator. We aimed to determine whether silybin reduced iron absorption in patients with hereditary haemochromatosis. In this crossover study, on three separate occasions, 10 patients who were homozygous for the C282Y mutation in the HFE gene (and fully treated) consumed a vegetarian meal containing 13.9 mg iron with: 200 ml water; 200 ml water and 140 mg silybin (Legalon Forte); or 200 ml tea. Blood was drawn once before, then 0.5, 1, 2, 3 and 4 h after the meal. Consumption of silybin with a meal resulted in a reduction in the postprandial increase in serum iron (AUC±s.e.) compared with water (silybin 1726.6±346.8 versus water 2988.8±167; P<0.05) and tea (silybin 1726.6±346.8 versus tea 2099.3±223.3; P<0.05). In conclusion, silybin has the potential to reduce iron absorption, and this deserves further investigation, as silybin could be an adjunct in the treatment of haemochromatosis.

    ABSTRACT: Plant-derived polyphenols are increasingly receiving attention as dietary supplements for the homeostatic management of inflammation, to support detoxication, and for anticancer, weight loss, and other benefits. Their pro-homeostatic effects on genes, transcription factors, enzymes, and cell signaling pathways are being intensively explored, but the poor bioavailability of some polyphenols likely contributes to poor clinical trial outcomes. This review covers four polyphenol preparations with poor bioavailability and their complexation into phytosomes to bypass this problem. Silybin and the other silymarin flavonolignans from milk thistle conserve tissue glutathione, are liver-protective, and have anticancer potential. Curcumin and its related diphenolic curcuminoids have potent antioxidant, anti-inflammatory, and anti-carcinogenic properties. The green tea flavan-3-ol catechins have antioxidant, anti-inflammatory, cardio- and neuro-protective effects, and anti-carcinogenic benefits, with fat oxidation effects coupled to weight loss. The complex grape seed proanthocyanidin mix (including catechin and epicatechin monomers and oligomers) counters oxidative stress and protects the circulatory system. For each of these preparations, conversion into phytosomes has improved efficacy without compromising safety. The phytosome technology creates intermolecular bonding between individual polyphenol molecules and one or more molecules of the phospholipid, phosphatidylcholine (PC). Molecular imaging suggests that PC molecule(s) enwrap each polyphenol; upon oral intake the amphipathic PC molecules likely usher the polyphenol through the intestinal epithelial cell outer membrane, subsequently accessing the bloodstream. PC itself has proven clinical efficacy that contributes to phytosome in vivo actions. As a molecular delivery vehicle, phytosome technology substantially improves the clinical applicabilities of polyphenols and other poorly absorbed plant medicinals.

    ABSTRACT: The poor and/or erratic oral bioavailability of polyphenolics can be improved using the PHYTOSOME delivery system, a strategy that enhances the rate and the extent of solubilization into aqueous intestinal fluids and the capacity to cross biomembranes. Phospholipids show affinity for polyphenolics, and form supramolecular adducts having a definite stoichiometry. This article reviews the preparation and characterization of PHYTOSOME complexes and their activity in various medicinal (cardiovascular, anti-inflammatory, hepatoprotective, anticancer) and cosmetic (skin aging) realms of application.
