Vitamin D has recently been given a lot of attention for its role in controlling insulin secretion. Many studies have spoken of its role in weight management, blood sugar control and many other metabolic variables.
In a randomized double-blind clinical trial, 210 people with vitamin D deficiency were randomly allocated into two groups receiving vitamin D (50,000 units per week) or placebo for 8 weeks.
Vitamin D levels were significantly increased in the group receiving vitamin D supplementation (13.7±5.2 unit increase versus 0.8±2.8). The increased levels of vitamin D lead to significant changes in fasting insulin levels (6.8±8.1 unit reduction versus 2.3±3.7), a 2-h insulin (31.1±34.9 unit reduction versus 4.5±24.6) and Homeostasis Model Assessment (HOMA) indices.
Correction of vitamin D deficiency leads to increased insulin sensitivity that was significantly able to maintain glucose in the normal range with lower levels of insulin.
维生素D在控制胰岛素分泌方面的作用最近备受关注。许多研究都提到了它在体重管理、血糖控制及许多其他代谢变量方面的作用。
在一项随机双盲临床试验中,210名维生素D缺乏者被随机分为两组,一组接受维生素D(每周50,000单位),另一组接受安慰剂,为期8周。
接受维生素D补充剂的组中维生素D水平显著升高(增加13.7±5.2单位,而另一组增加0.8±2.8)。维生素D水平的升高导致空腹胰岛素水平(降低6.8±8.1单位,而另一组降低2.3±3.7)、2小时胰岛素水平(降低31.1±34.9单位,而另一组降低4.5±24.6)和稳态模型评估(HOMA)指数发生显著变化。
纠正维生素D缺乏会导致胰岛素敏感性增加,显著能够以较低的胰岛素水平将血糖维持在正常范围内。
