“…Dozens of controlled trials have evaluated the effects of CoQ10 on CVD. Early studies summarized in the prior edition of this volume showed that CoQ10 has benefi cial subjective (quality of life) and objective (increased left ventricular ejection fraction, improved stroke index scores, decreased hospitalizations) effects, but more recent studies have been less supportive [ 226 ].…”

IntroductionThis chapter focuses on the rationale and evidence base for the use of dietary supplements for both maintaining health and decreasing the risks of some common chronic diseases. This review also updates the information in a review of data through 2009 on nutritional supplements for older adults [ 1 ] by summarizing evidence published in 2009-2013 from systematic reviews and meta-analyses of randomized clinical trials with disease endpoints. The chapter concludes with recommendations for assessing dietary supplement use in older persons and suggestions for counseling them. We have categorized these supplements according to their active ingredient(s), and we pay particular attention to

Qualitative analysis was conducted using thin layer chromatography (TLC) to determine the presence of other oils containing triglyceride structures that were mixed in four imported saw palmetto extracts. Two different eluting solvents were used to distinguish between ethyl ester and triglyceride components and to identify triglyceride spots. Solvent A was made by mixing [hexane: ethyl ether: acetic acid = 90: 10: 1] and [hexane: ethyl ether: methanol: acetic acid = 85: 15: 3: 2] in a ratio of 1:1. Solvent B was made with toluene: ethyl ether: acetic acid = 70: 30: 1. In solvent A, both triglyceride and ethyl ester were detected in the standard saw palmetto extract, but weak spots were detected. In contrast, strong triglyceride spots were observed in the four imported extracts. In solvent B, similarly to solvent A, weak spots were confirmed in the standard saw palmetto extract and strong triglyceride spots were confirmed in four imported extracts. These results suggest the possibility of these four imported extracts being mixed with other oils and fats containing triglyceride structures. This data is valuable for verifying the accuracy of import declarations involving saw palmetto extract and assessing the potential adulteration with other oils and fats. It serves as a foundational dataset for further analysis.
