There is some indication from dose–response assessments that

the n-3 LCPUFAs may be efficacious in reducing fasting TG levels when consumed at doses even lower than these recommended doses. In a recent meta-analysis of randomized controlled trials, it was demonstrated that TG levels are dose-dependently selleck compound reduced by the n-3 LCPUFAs, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) [5]. Even though there were only a limited number of data points in the dose–response assessment at EPA and DHA intakes of less than 1 g/day, there was some suggestion that even modest intakes of the n-3 LCPUFAs could be beneficial with regards to reducing fasting serum TG levels. Likewise, in a dose- response assessment restricted to algal sources of DHA, Ryan et al. demonstrated a dose–response relationship between dose of DHA and the reduction in fasting buy GDC-0068 TG level [6]. Although this latter dose–response assessment was restricted to studies conducted with algal DHA, it has been reported that EPA and DHA have similar TG-reducing effects when administered individually [7], [8] and [9]. Krill oil is processed from Antarctic krill (Euphausia superba), small shrimp-like animals of the crustacean superorder Eucarida found in the Southern Ocean. Krill oil is a unique source of EPA and DHA

because unlike most other oils of marine origin, the major part of EPA and DHA in krill oil occurs naturally in phospholipid (PL) and not in TG form [10] and [11]. There are indications that, compared to the delivery of EPA and DHA in the TG form, the delivery of EPA and DHA in the PL form results in higher tissue levels of EPA and DHA [12], [13], [14] and [15]. Krill oil is characterized by a higher amount of EPA compared to DHA, with a ratio of 2 to 1. While there is consensus in the scientific literature that the dietary intake of both EPA and DHA (either individually or in combination) can reduce elevated TG levels, DHA (but not EPA) has been suggested to be responsible for a simultaneous elevation in LDL-C seen particularly in patients with very high

(>500 mg/dL) TG levels [8], [9] and [16]. In rodents, krill oil supplementation Racecadotril has been shown to suppress lipid synthesis by up-regulating genes involved in lipid oxidation and down-regulating those that are involved in lipogenesis [17] and [18]. Blood TG and cholesterol levels were significantly reduced after the administration of krill oil, both in normolipidemic rats [19] and in rats with diet-induced hyperlipidemia [20]. Pre-clinical experiments also suggest that the endocannabinoid system plays a major role in the action of krill oil on fat distribution in obese rats [12] and [21]. Thus, the objective of the clinical study described herein was to test our hypothesis that krill oil can lower serum TG levels in humans with borderline-high or high fasting serum TG levels (i.e., 150–499 mg/dL).
