Coenzyme Q10 supplementation: Efficacy, safety, and formulation challenges.

World population growth and aging are posing unprecedented challenges in sustaining the health of 9.1 billion people that will be occupying the planet by 2050. Although noncommunicable diseases such as cardiovascular and neurodegenerative diseases, cancer, and diabetes are among the top 10 global causes of death, they can be prevented by risk factor reduction, early detection, and adequate treatment. Since a healthy diet along with dietary supplementation could play an important role to reduce morbidity and cut off its associated health care costs, research in the food and nutrition area is required to find solutions to global challenges affecting health. As a result of the healthy living trend, dietary supplements category is growing fast, leading to an urgent need for dietitians, physicians, and policy makers to broaden the scientific evidence on the efficacy and safety of a wide range of active ingredients. Coenzyme Q10 (CoQ10), as the third most consumed dietary supplement, and as a potential candidate for the treatment of various noncommunicable diseases that are among the global top 10 causes of death, has gained interest over years. Scientific evidence regarding mainly CoQ10 efficacy and safety, as well as formulation challenges, is addressed in this review.

Therapeutic potential of nicotinamide adenine dinucleotide (NAD).

Nicotinamide adenine nucleotide (NAD) is a small ubiquitous hydrophilic cofactor that participates in several aspects of cellular metabolism. As a coenzyme it has an essential role in the regulation of energetic metabolism, but it is also a cosubstrate for enzymes that regulate fundamental biological processes such as transcriptional regulation, signaling and DNA repairing among others. The fluctuation and oxidative state of NAD levels regulate the activity of these enzymes, which is translated into marked effects on cellular function. While alterations in NAD homeostasis are a common feature of different conditions and age-associated diseases, in general, increased NAD levels have been associated with beneficial health effects. Due to its therapeutic potential, the interest in this molecule has been renewed, and the regulation of NAD metabolism has become an attractive target for drug discovery. In fact, different approaches to replenish or increase NAD levels have been tested, including enhancement of biosynthesis and inhibition of NAD breakdown. Despite further research is needed, this review provides an overview and update on NAD metabolism, including the therapeutic potential of its regulation, as well as pharmacokinetics, safety, precautions and formulation challenges of NAD supplementation.

Trends in the food and sports nutrition industry: A review.

This revision intends to provide an overview on the major and emerging trends in food and nutrition. Food scientists and dietitians should keep an eye on the trends shaping the food industry in order to understand consumer changes in preferences, expectations and dietary patterns; and to identify those areas that should be added to the research agenda. In addition, to comprehend the major drivers of change in the food industry, global consumer trends are also reviewed in this article. Global concerns are shaping consumer attitudes, and with an easier access to information and an unprecedented consumer power through social media, the food industry should quickly adapt to meet consumer needs. In order to meet these objectives, this review is organized in three different but interrelated sections: global consumer trends, food and nutrition trends, and trends in sports foods and nutrition. This last one is also included due to its influence over food trends, and its significant relevance as a category and food trend.
