Nutritional supplement

Yeasts are also used as nutritional supplements. It is often referred to as nutritional yeast when sold as a dietary supplement. Nutritional yeast, inactivated yeast, usually S. cerevisiae, is an excellent source of protein and vitamins, especially the B-complex vitamins, as well as other minerals and

Food. Lecithin is a widely used nutritional supplement rich ia polyunsaturated fatty acids, phosphatidylcholine, phosphatidylethanolamine, phosphatidjhnositol, and organically combiaed phosphoms, with emulsifying and antioxidant properties (38). 

Vitamins are sold for direct appHcation to foods and animal feeds. In addition, they are further processed into nutritional supplements. This last market is particularly significant in the United States. In many other countries, vitamins are regulated as dmgs, leading to a much lower supplement usage. 

As a therapeutic agent, ch oline is adininistered orally in the form of symps or elixers containing the chloride, citrates or bitartrate, or in the form of compressed tablets or capsules of the dihydrogen citrate. Choline is also given in small doses as a nutritional supplement in combination with a variety of other materials. In dry pharmaceutical-dosage forms, the dihydrogen citrate is usually preferred because of its lower tendency to absorb atmospheric moisture. Both salts have been used parenteraHy. 

When obtaining the drug history, the nurse must always question the patient about the use of herbs, teas, vitamins, or other nutritional or dietary supplements. Many patients consider herbs as natural and therefore safe It is also difficult for some to report the use of an herbal tea as a part of the health care regimen. Display 1-4 identifies teaching points to consider when discussing the use of herbs and nutritional supplements with patients. Although a complete discussion about the use of herbs is beyond the scope of this book, it is important to remember that the use of herbs and nutritional supplements is commonplace in many areas of the country. To help the student become more aware of herbal therapy and nutritional supplements, Appendix B gives... 

Sucrose caramels have been produced under anhydrous thermal conditions that are designed to maximize the content of fructose-rich oligosaccharides.100-102 These sucrose thermal oligosaccharide caramels (STOC) have been tested in animals as a nutritional supplement. Improved weight gains and feed conversion, and increased levels of bifidobacteria (see section VIII) were observed in broiler chickens that were fed this supplement.103... 

The carotenoids are the most widespread group of pigments in nature, with an estimated yield of 100 million tonnes per annum. They are present in all photosynthetic organisms and responsible for most of the yellow to red colours of fruits and flowers. The characteristic colours of many birds, insects and marine invertebrates are also due to the presence of carotenoids, which have originated in the diet. Animals are unable to synthesise carotenoids de novo, and so rely upon the diet as the source of these compounds. Carotenoids found in the human diet are primarily derived from crop plants, where the carotenoids are located in roots, leaves, shoots, seeds, fruit and flowers. To a lesser extent, carotenoids are also ingested from eggs, poultry and fish. Commercially, carotenoids are used as food colourants and in nutritional supplements (Table 13.1). Over recent years there has been considerable... 

The 2000 U.S. Pharmacopoeia and National Formulary, USP 24-NF 19, was published in October 1999. It became official on 01.01.2000. USP-NF is one of, if not the most, widely recognized of the world s pharmacopoeial compendia of standards for drug strength, quality, purity, packaging, labelling and storage. USP-NF also provides standards for devices and diagnostics, as well as nutritional supplements. 

Niacin (vitamin B3) has broad applications in the treatment of lipid disorders when used at higher doses than those used as a nutritional supplement. Niacin inhibits fatty acid release from adipose tissue and inhibits fatty acid and triglyceride production in liver cells. This results in an increased intracellular degradation of apolipoprotein B, and in turn, a reduction in the number of VLDL particles secreted (Fig. 9-4). The lower VLDL levels and the lower triglyceride content in these particles leads to an overall reduction in LDL cholesterol as well as a decrease in the number of small, dense LDL particles. Niacin also reduces the uptake of HDL-apolipoprotein A1 particles and increases uptake of cholesterol esters by the liver, thus improving the efficiency of reverse cholesterol transport between HDL particles and vascular tissue (Fig. 9-4). Niacin is indicated for patients with elevated triglycerides, low HDL cholesterol, and elevated LDL cholesterol.3...

Regardless of whether the microbes are native or artificially introduced into the soil, it is important to understand the mechanisms by which they degrade or detoxify hazardous pollutants through their metabolic activity. Understanding these mechanisms is essential for the proper design of bioremediation systems that provide the optimum conditions and the required nutritional supplements for the specific microbial process. 

As has been pointed out earlier in this chapter, the dietary consumption and historical medicinal use of carotenoids has been well documented. In the modern age, in addition to crocin, 3.7, and norbixin, 3.8, several carotenoids have become extremely important commercially. These include, in particular, astaxanthin, 3.6 (fish, swine, and poultry feed, and recently human nutritional supplements) lutein, 3.4, and zeaxanthin, 3.3 (animal feed and poultry egg production, human nutritional supplements) and lycopene, 3.2 (human nutritional supplements). The inherent lipophilicity of these compounds has limited their potential applications as hydrophilic additives without significant formulation efforts in the diet, the lipid content of the meal increases the absorption of these nutrients, however, parenteral administration to potentially effective therapeutic levels requires separate formulation that is sometimes ineffective or toxic (Lockwood et al. 2003). 

Based on these capabilities, the RRS detection method has already found commercial application in the nutritional supplement industry (BioPhotonic Scanner , Pharmanex LLC, Provo, and Utah), which has placed thousands of portable instruments with their customers for rapid optical measurements of dermal carotenoid levels, and which has further developed the instrumentation for rugged field use (Bergeson et al. 2008).

Isolated polynucleotide clusters from Rhodococcus opacus which encode four polypeptides possessing the activities of a NHase (a and /3 subunits), an auxiliary protein P15K that activates the NHase, and a cobalt transporter protein were expressed in Escherichia coli DSM 14459 cells [34]. Methionine nitrile was added continuously to a suspension of the transformant cells (5.6% w/v of wet cells) in phosphate buffer (50 mM, pH 7.5) at 20 °C, at a rate where the nitrile concentration did not exceed 15 g L 1 while maintaining the pH constant at 7.5. After 320 min, the nitrile was completely converted into amide, corresponding to a final product concentration of 176 gL1.4-Methylthio-a-hydroxybutyramide is readily hydrolyzed with calcium hydroxide, where the calcium salt of 4-methylthio-a-hydroxybutyric acid (MHA) can be directly used as a nutritional supplement in animal feed as an alternative to methionine or MHA. 

The business of BioZone Laboratories concerns development, manufacturing, and marketing of products and technologies, such as drugs and preparations, cosmetics, and nutritional supplements. All product lines are supported by proprietary technologies, and research and development activities are considered to be of a core importance for the business. The IP estate is also available for commercialization, particularly in the prescription area, for which several drug delivery systems and a prescription version of Inflacin were developed.
