ABSTRACT Hypovitaminosis D appears to be on the rise in young children, with implications for skeletal and overall health.
The objective of the study was to compare the safety and efficacy of vitamin D2 daily, vitamin D2 weekly, and vitamin D3 daily, combined with supplemental calcium, in raising serum 25-hydroxyvitamin D [25(OH)D] and lowering PTH concentrations.
This was a 6-wk randomized controlled trial.
The study was conducted at an urban pediatric clinic in Boston.
Forty otherwise healthy infants and toddlers with hypovitaminosis D [25(OH)D < 20 ng/ml] participated in the study.
Participants were assigned to one of three regimens: 2,000 IU oral vitamin D2 daily, 50,000 IU vitamin D2 weekly, or 2,000 IU vitamin D3 daily. Each was also prescribed elemental calcium (50 mg/kg.d). Infants received treatment for 6 wk.
Before and after treatment, serum measurements of 25(OH)D, PTH, calcium, and alkaline phosphatase were taken.
All treatments approximately tripled the 25(OH)D concentration. Preplanned comparisons were nonsignificant: daily vitamin D2 vs. weekly vitamin D2 (12% difference in effect, P = 0.66) and daily D2 vs. daily D3 (7%, P = 0.82). The mean serum calcium change was small and similar in the three groups. There was no significant difference in PTH suppression.
Short-term vitamin D2 2,000 IU daily, vitamin D2 50,000 IU weekly, or vitamin D3 2,000 IU daily yield equivalent outcomes in the treatment of hypovitaminosis D among young children. Therefore, pediatric providers can individualize the treatment regimen for a given patient to ensure compliance, given that no difference in efficacy or safety was noted among these three common treatment regimens.

    ABSTRACT: ABSTRACT Introduction Vitamin D3 (cholecalciferol) is unique in nutritional science for its impressive safety, low cost, and wide range of clinical applications. The breadth of its clinical applications provides evidence of the importance of this nutrient/hormone in a wide range of physiologic functions, including calcium absorption and bone health, maintenance of gut mucosal integrity, maintenance of muscle strength, anti-inflammatory benefits, modulation of NFkB, antirheumatic and anti-autoimmune benefits, immunosupportive and anti-infection benefits, anti-cancer benefits, cardioprotection, neuroprotection, and ability to prevent deficiency-induced musculoskeletal pain, weakness, and seizures. In 2004, the current author lead the writing of an important review paper for the integrative medicine and functional medicine communities in Alternative Therapies in Health and Medicine, and this paper sought to effect a "paradigm shift" in the way vitamin D is perceived by clinicians with the hope that more clinicians would embrace its use for the benefit of their practices and patients. The purpose of this article is to briefly outline the arguments for and against and to invite proponents of "medically endorsed/promoted nutritional deficiency" to clearly articulate their position, its mechanisms, and to provide a risk/cost-benefit ratio substantiating what is otherwise contrary to the bulk of science and clinical practice on this topic.

    ABSTRACT: Objective: To determine whether vitamin D supplementation of indigenous school children living at high altitude who are vitamin D insufficient improves lipid profile. Methods: A prospective two-year study evaluated 60 children (29 males) from Hogar School who received 100,000 units of vitamin D and 36 children (16 males) from Sosa School who received 50,000 units. Anthropometric measures, Triglycerides (TG), HDL-C, TG/HDL-C, and vitamin D levels were measured in November 2011 and in November 2013. Results: Children aged 8.8±2 years with mean z-BMI (-0.43) were evaluated. After vitamin D supplementation, mean vitamin D levels increased from 14.7 to 32.1ng/mL (p Conclusions: Indigenous children who received 100,000 U of vitamin D significantly improved vitamin D and lipid levels compared to children who received 50,000 U, suggesting that optimal vitamin D levels are associated with a healthier lipid profile.
