根据《中国居民膳食营养素参考摄入量》当中明确建议,0～64岁的人群,每天需要摄入400IU的维生素D(IU是国际单位,400IU维生素D为0.01 毫克)。 根据中华人民共和国卫生行业标准(WS/T)《人群维生素D缺乏筛查方法》的规定,当血液中25-羟基维生素D水平大于20ng/mL时,表明维生素D的营养状况是正常的,低于12ng/mL时即为缺...
D3 参与人体的骨骼代谢,提高免疫功能,调节情绪。 由于现代人缺乏户外活动时间,且暴露的皮肤过少,导致身体无法经由阳光合成足够的维生素D。 特别是女性,青少年(上学)和缺乏室外活动的老人,需要外部补充。 使用方法:胶囊形式可餐后服用,春夏阳光较为充足,建议1000IU;秋冬阳光较少,建议5000IU。 消费者告知书 您好!为帮...
[1] IU is still commonly seen alongside μg, so it’s good to become familiar with both units: 40 IU is equivalent to 1 μg. How many grams of vitamin D should I take per day? The ideal daily dose of vitamin D should correspond to its recommended daily allowance (RDA), which is...
Among 131 individuals using 2001 IU/d vitamin D3 or more, 4 of 24 individuals (17%) with vitamin D level less than 20 ng/mL had test results positive for COVID-19, while 2 of 107 individuals (2%) with a vitamin D level of 20 ng/mL or higher had test results positive for COVID...
·mL−1or less, Gallagheret al.55reported that a vitamin D dose of 800 IU per day (in conjunction with sufficient calcium intake; 1 200–1 400 mg) increased 25(OH)D levels greater than 20 ng·mL−1in 97.5% of the women. This level, as indicated by the Institute of...

Vitamin D deficiency is typically defined as circulating 25D concentrations Ͻ20 ng/mL (50 nM) (7,9). In this state, the subsequently low ionized calcium (iCa) concentration stimu- lates PTH secretion, which eventually leads to increased 1,25D synthesis. The elevated PTH concentrations also...
Oral vitamin D 3 400–4000 IU/day (effectively 400–1860 IU/day) resulted in a return to normal of the serum vitamin D metabolites, correction of the impaired intestinal calcium absorption and healing of the osteomalacia. Increases in serum calcium, phosphate, and the renal tubular reabsorption...
Animals were euthanized to isolate arteries for histomorphometric and immunohistochemical studies. Animals had graded levels of serum 25(OH)D; vitamin D-deficient (15.33 ± 1.45 ng/ml), vitamin D-sufficient + 1,000 IU oral vitamin D post-intervention (32.27 ± 1.20 ng/ml), and vitamin D-...
In CKD patients, supplementation with cholecalciferol showed a significant increase in serum 25(OH)D concentration and a decrease in PTH levels when compared with the placebo [34]. More recently, Westerberg reported that high-dose cholecalciferol (8000 IU/day) in patients with CKD stages 3–4 ...
