Alpha-lipoic acid as a dietary supplement: Molecular mechanisms and therapeutic potential

Alpha-lipoic acid (LA) has become a typical ingredient in vitamin pill formulas, anti-aging supplements, and even pet food. it’s well-defined as a medical aid for preventing diabetic polyneuropathies, and scavenges free radicals, chelates metals, and restores intracellular  glutathione levels that otherwise decline with age. however do the organic chemistry properties of los angeles relate to its biological effects? Herein, we have a tendency to review the molecular mechanisms of los angeles discovered victimization cell and animal models, and also the effects of los angeles on human subjects. [2]

Dietary supplement use among U.S. adults has increased since NHANES III (1988-1994).

KEY FINDINGS: Use of dietary supplements is common among the U.S. adult population. Over four-hundredth used supplements in 1988-1994, and over half in 2003-2006.

Use of supplemental atomic number 20 raised from twenty eighth throughout 1988-1994 to sixty one throughout 2003-2006 among ladies aged sixty and over. Use of supplements containing B complex among ladies aged 20-39 didn’t increase since 1988-1994. In 2003-2006, thirty fourth of girls aged 20-39 used a dietary supplement containing B complex. [3]

Poor chemical and microbiological quality of the commercial milk thistle-based dietary supplements may account for their reported unsatisfactory and non-reproducible clinical outcomes

Herbal-based dietary supplements became progressively common. The extract from milk weed (Silybum marianum), is commonly used for the treatment of liver diseases.

Effect of Herbal Dietary Supplement White Ginseng (Panax ginseng Meyer) on Sprague-Dawley Rats Performance

Aim: The aim of this study was to look at the dietary effects of white ginseng (WG) supplementation on physical performance and expression of genes in colon and small intestine of rats.

Study Design: Male Sprague-Dawley rats aged eight weeks (young) and forty four weeks (aged) old-time were allotted into 3 treatment teams (n = 5) and fed a customary eutherian chow management diet or a diet containing two hundred mg/kg b.w (low-dose) or five hundred mg/kg b.w (high-dose) WG.

Place and period of Study: Department of Food Science and Technology, school of Agriculture and Biotechnology, CNU, Daejeon. The experiment lasted for eleven weeks within the year 2014. [5]
