Although calcium carbonate taken on an empty stomach is poorly absorbed by people with hypochlorhydria, calcium carbonate taken with food appears to be well absorbed regardless of gastric acid secretory capacity.维生素 D Vitamin D维生素 D 增加钙的吸收，促进骨胳、牙齿正常发育。在绝经后妇女的临床研究中发现，每天补充800 IU的维生素D可以减少骨折的发生（每天400 IU则无效）。镁 Magnesium镁是构成骨胳的主要成分，是人体不可缺少的矿物质元素之一。它能辅助钙和钾的吸收。骨质疏松一般都伴随着“低镁”。一项临床试验结果表明绝经后妇女每天补充250－750 mg的镁1-2年，71%的试验者骨密度都有提高。维生素 K Vitamin K成熟的成骨细胞合成和分泌骨钙蛋白，后者与钙离子结合，将钙离子固定下来，这样骨骼才得以骨质化。骨钙蛋白必须要有维生素K才能正常工作。 无数的临床试验结果表明补充维生素K可以减缓骨质疏松，预防骨折。锶 Strontium锶是一种微量元素，每天食物中可以摄取2－3 mg。 锶的作用是促进成骨，进而增加骨密度。.In double-blind trials, strontium supplementation (170-680 mg per day) significantly increased bone mineral density and decreased fracture incidence in postmenopausal women. Preliminary evidence suggests that 170 mg per day is at least as effective as 680 mg per day for fracture prevention, which raises the possibility that even lower dosages would be effective.
