bone Health Mineral Rights But calcium isn't the only mineral in town. It's calcium's partnership with phosphorus, potassium, zinc, manganese, copper, and other minerals that "has proven critical for improving bone health," says Max Motyka, director of the human products division at Albion Laboratories Inc. (Clearfeld, UT). Magnesium, in particular, pays bonehealth dividends by suppressing parathyroid hormone release and thus decreasing osteoclast activity. "Tis has the net efect of drawing calcium into the bone structure," says Motyka. "Without magnesium, calcium may not be fully utilized." But, for any bone-building mineral to be fully utilized, we must consume it in a bioavailable form. Motyka notes, for example, that individuals vary widely in their ability to absorb diferent forms of iron. Robab Emami, technical services manager at AMT Labs and Kelatron Corp. (Ogden, UT), divisions of Innophos Inc., adds that in the acidic environment of the stomach, minerals dissociate into charged ions that are attracted to other charged stomach contents—say, fber and fat. "Terefore, only a small portion of the mineral content will be absorbed," she says. Most minerals naturally occur in an inorganic state and require conversion to a stable organic form for optimal absorption. Tis conversion process is called chelation, says Emami, "where a metal is bonded to an organic ligand, such as an amino acid, to protect the mineral from ionization and optimize its absorption in the body." Chelation minimizes mineral dissociation in the stomach, which Emami says not only increases absorption but reduces stomach irritation, too. To be successful, mineral chelates must make it through the stomach intact, so they can pass into the small intestine—the duodenum and jejunum sections—where their chances of absorption are much Grape Seed Extract Straight from the Source! A Powerful All-Natural Antioxidant FDA-GRAS Affirmed for Foods & Beverages greater, says Motyka. To produce its specialty Calcium Bisglycinate Chelate, his company uses a patented technology to bond chelated minerals to amino acid ligands, "creating a stable molecule with a neutral charge," he says. "Tis molecule passes through the stomach intact and is available for absorption. Tis is particularly important for bone-health nutrients because the body recognizes the amino acid components as food and absorbs them a little more easily." And, while increased mineral uptake may not top the list of prebiotic fber's most ballyhooed benefts, Patrick Luchsinger, marketing manager of nutrition at Ingredion (Westchester, IL), points out that his company's patented prebiotic short-chain fructooligosaccharide, NutraFlora, improves bone strength by improving absorption of minerals like calcium. But how? As benefcial gastrointestinal bacteria ferment the fber, they produce short-chain fatty acids that "nourish the gut tissues through which minerals are absorbed," Luchsinger says, "while at the same time lowering the pH to an optimal level for ionizing and solubilizing minerals." Te most recent study on the fber's relationship to bone health has been submitted for review and publication, and scientifc studies show that about 3.2 g of NutraFlora per day may signifcantly and immediately improve calcium and magnesium absorption in human subjects.

But research raises questions about whether calcium supplementation may do more harm than good—for the heart, that is. Te results of an epidemiological study published in 2013 in the Journal of the American Medical Association (Xiao et al.) indicate that daily intake of 1000 mg of supplemental calcium correlated with signifcant increases in death from cardiovascular disease (CVD), particularly in men. And, notes NattoPharma's Badmaev, further studies reveal similar risks in women. "Use of calcium supplements with or without vitamin D was associated with a signifcant 24% increase in risk of coronary heart disSeptember 2013 ■ NUTRITIONAL OUTLOOK ES314194_NO1309_044.pgs 08.30.2013 23:49 UBM
