An increase of only 1 mg of soy isoflavones per day has been associated with a yearly increase in bone mineral concentration of .018-.028%, according to a study of Chinese postmenopausal women. The double-blind, randomized, placebo-controlled study included dosages of 40mg or 80mg of aglycones daily, or a placebo. All women were given 500mg of calcium and 125IU of vitamin D3. The results showed that women taking the higher (80mg) dosage of the isoflavone showed a significant increase in bone mineral concentration. The isoflavone used in the study, SoyLife, is produced by Acatris; this is the third study showing the positive bone effects of SoyLife. Acatris Inc., Laurent Leduc, 905-829-2414
