补充剂不能预防成年人的骨折,并且可能增加胃肠道问题,结石和心血管事件的风险. 它们在骨质疏松症治疗中的作用有限.
科学领域:
- 骨健康和骨质疏松症研究
- 心血管风险评估心血管风险评估
- 营养补充剂的疗效 营养补充剂的疗效
背景情况:
- 骨质疏松症是一个重大的公共卫生问题,历史上建议补充来预防骨折.
- 新出现的证据质疑补充剂的有效性和安全性,特别是在心血管结果方面.
研究的目的:
- 评估补充剂在预防骨折方面的有效性.
- 审查补充剂的不良影响,重点关注心血管健康.
- 确定补充剂在骨质疏松症管理中的当前作用.
主要方法:
- 对补充剂和骨折预防的试验证据的系统审查.
- 临床试验中不良事件的元分析,包括心肌梗塞 (MI) 风险.
- 关于循环水平和心血管疾病 (CVD) 的门德尔随机化研究的分析.
主要成果:
- 补充并不能预防社区成年人的骨折.
- 常见的副作用包括胃肠道问题和结石;心脏病发作风险可能增加10-20%.
- 急性摄入增加了血液凝结能力,化倾向和血压,可能增加心血管疾病风险.
结论:
- 补充剂在预防或治疗骨质疏松症方面发挥的作用有限,因为其他治疗方法,如雌激素和双酸盐,在不同时使用的情况下都有效.

Skeleton and Calcium Homeostasis
Hormones and Bone Tissue
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Synthesis and Functions of Calcitonin
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...
Feedback Regulation of Calcium Concentration
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...
Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
Essential Minerals for Bone Health
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
