BIOAVAILABILITY, ABSORBABILITY AND STABILITY COMBINED! POWDER SELENIUM prevents problems in farrowing, such as high piglet mortality, lethargic and weak piglets, as well as mulberry heart disease. It enhances muscle tone and strength of sows, preventing dystocia and related stillbirths. It is a primary component of Glutathione peroxidase (GPX), that functions to protect the cell membrane from oxidation preventing carcass paleness, drip loss and increased shelf-life of eggs in poultry SELENIUM CHELATE* is a 4th generation chelate**, produced in a three stage chelation process utilizing final form amino acids as ligands, assuring complete and stability SELENIUM CHELATE* is non-buffering to gastric pH, helping maintain optimum High Bioavailability Selenium Supplement SELENIUM CHELATE CURRENT NUTRITION NUTREX TECHNOLOGY EXPONENTS XPONENTS chelation of selenium ions, resulting to unequalled bioavailability, absorbability acidity for protein digestion and immune enhancement SELENIUM CHELATE* is non-precipitative in intestinal pH—does not form gut harmful “magma” SELENIUM CHELATE* is non-reactive to vitamins and other vital nutrients in the gut—resulting to unimpaired vitamin bioavailability SELENIUM CHELATE* is independently absorbed and is not antagonized by other minerals and substances (e.g. phytic acid) SELENIUM CHELATE* is the superior, high bioavailability selenium supplement for predictable and cost effective growth performance enhancement * As compared with inorganic selenium **Should be differentiated with “dry blends/complexes”, which are mere physical attachment of the amino acids with the metal (tends to separate into its component parts in acidic pH) CONTENTS Selenium amino acid chelate 1M µg* (bioavailable Selenium) Carrier calcium carbonate q.s. ad 1 kg *Equivalent to 1,000 ppm RECOMMENDED USE AND DOSAGE Use at 80-300g/ton of feed to achieve 0.08-0.3 ppm active bioavailable Selenium PACKAGING 25 kg box A Performance Enhancing Nutritional Product of: AGRIaccess 4714 175th ST SE Bothell WA 98012 USA www.agriaccess.com METABOLIC ROLE OF SELENIUM 1. 2. 3. recently recognized as one of the more essential micronutrient for humans and animals - multi-organ, protective and regulatory role primary metabolic role - major antioxidant - as a vital component of GLUTATHIONE PEROXIDASE (GPX1) secondary roles - functional part of various enzymes (GPX2, GPX3, GPX4, iodothyronine deiodonases, thioredoxin reductase selenoprotein P & W, and functional mitochondrial proteins ) acid and glycine major antioxidant enzyme in humans and animals (Rotuck et.al. 1973, X.G. Lei 1999) GPX1 cellular location, present in most body cells composed of selenium and three amino acids — cysteine, glutamic THE SELENIUM METHIONINE ISSUE Taking the Animal Perspective Selenomethionine is the storage form of selenium in PLANTS. The functional, and to a certain extent storage, and plasma transport form in ANIMALS is selenocysteine (Hill et.al.1991) Methionine is convertible to cysteine. But as methionine is a limiting essential amino acid, and cysteine is a common, non-essential amino acid, in the animal there practically exists a RARE NEED TO CONVERT METHIONINE TO CYSTEINE. DIAGRAM OF SELENIUM METABOLISM IN MAMMALS and in the tRNA Se joins the amino acid Serine to form selenoprotein THUS - if selenomethionine is absorbed - chances are it will NOT be converted to selenocysteine - selenium in selenomethionine will either be extracted and combined with required amino acids, OR remain as-is, used as methionine or excreted. - actual bioavailability of selenomethionine is much lower than the GPX composite amino acid chelates (Sunde 1999) Shows selemethionine has to pass thru the same breakdown and recombination process, then the extracted Se joins the intracellular inorganic mineral pool, COMPARATIVE BIOAVAILABILITY OF DIFFERENT SELENIUM FORMS HIGH PERFORMANCE LIQUID CHROMATOGRAPHY (HPLC) PROFILE Selenium Amino Acid Chelate 1% _________________________________ Form Bioavailability ————————————————– Se amino acid >90% Se methionine yeast <45% Se methionine complex <25% Na selenite (inorganic) <0.05% ————————————————– (HPLC is the preferred screening or assay tool of biotechs for organic molecules/materials; (Methionine included in solution to provide perspective)
