Abstract
Background: Coenzyme Q10 (CoQ-10) plays a vital role in cellular energy production and protection against oxidative stress. However, its absorption from orally administered forms is limited due to its poor water solubility and relatively large molecular weight. While co-ingesting CoQ-10 with a fatty meal can enhance absorption, this approach is not always practical. The aim of this study was to evaluate whether a liposomal formulation of CoQ-10 could improve its absorption compared with standard CoQ-10 without the need for the concurrent consumption of fatty foods.
Methods: In a randomized, double-blind, placebo-controlled, crossover study design, 7 men and 11 women (n = 18; age: 33.5 ± 6.4 years, height: 171.2 ± 8.1 cm, weight: 65.6 ± 8.8 kg) ingested a single dose of placebo (PLA), 100 mg of unformulated CoQ-10, or 100 mg of liposomal CoQ-10 (Lipo CoQ-10, LipoVantage®, Specnova, LLC, Tyson Corner, VA, USA). Venous blood samples were collected at 0, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, and 24 h after ingestion and analyzed for plasma CoQ-10 concentrations.
Results: CoQ-10and Lipo CoQ-10 demonstrated significantly greater Cmax and AUC0-24 compared with placebo (p < 0.001). Additionally, Lipo CoQ-10 had significantly higher Cmax (+31.3%, p < 0.001) and AUC0-24 (+22.6%, p < 0.001) values as compared with CoQ-10. CoQ-10 formulations were well-tolerated, with no significant changes in safety markers (blood pressure, renal function, liver enzymes, and lipid profile; p > 0.05), indicating a favorable safety profile.
期刊介绍：
No subject pertains more to human life than nutrition. The aim of Frontiers in Nutrition is to integrate major scientific disciplines in this vast field in order to address the most relevant and pertinent questions and developments. Our ambition is to create an integrated podium based on original research, clinical trials, and contemporary reviews to build a reputable knowledge forum in the domains of human health, dietary behaviors, agronomy & 21st century food science. Through the recognized open-access Frontiers platform we welcome manuscripts to our dedicated sections relating to different areas in the field of nutrition with a focus on human health.
Specialty sections in Frontiers in Nutrition include, for example, Clinical Nutrition, Nutrition & Sustainable Diets, Nutrition and Food Science Technology, Nutrition Methodology, Sport & Exercise Nutrition, Food Chemistry, and Nutritional Immunology. Based on the publication of rigorous scientific research, we thrive to achieve a visible impact on the global nutrition agenda addressing the grand challenges of our time, including obesity, malnutrition, hunger, food waste, sustainability and consumer health.
