Total Cholesterol | HDL-C | LDL-C | Triglycerides | |
<35 ng/ml | 187 | 42 | 97 | 160 |
35–61ng/ml | 156 | 40 | 94 | 148 |
>61 ng/ml | 147 | 48 | 79 | 132 |
Aim: The aim of this study was to evaluate the effect of vitamin D supplementation in patients with type 2 diabetes mellitus (T2DM) with regard to their glycemic control and lipid profile.
Methods: One hundred subjects with diabetes were recruited and given 4500 IU/day of vitamin D for 2 months. 25-Hydroxyvitamin D [25(OH)D], fasting blood glucose (FBG), glycosylated hemoglobin A1c (HbA1c), and lipid profile were measured pre- and postsupplementation.
Results: There was a significant increase in the mean value of 25(OH)D level after supplementation (baseline level 16 ± 5.3 ng/ml vs. after supplement level 49.2 ± 17.7 ng/ml, p < 0.05). Both FBG and HbA1c but not lipid profile were significantly decreased after supplementation. However, the univariate general linear model between 25(OH)D percentiles and lipid profile levels showed that subjects with diabetes with high 25(OH)D levels (>61 ng/ml) had significantly lower levels of total cholesterol and low-density lipoprotein cholesterol (LDL-C) in comparison to those in the low or middle percentiles. Furthermore, participants in a higher percentile had a significantly higher level of high-density lipoprotein cholesterol (HDL-C) than those in the middle percentile. Lipid profile levels were not affected by the supplement except for triglycerides (TG) levels in females, which were significantly decreased.
Conclusions: Vitamin D supplementation may be beneficial to subjects with diabetes because it improved glycemic control. Subjects with diabetes with high 25(OH)D levels (>61 ng/ml) had better lipid profiles.

Overview Diabetes and vitamin D contains the following summary
- Diabetes is 5X more frequent far from the equator
- Children getting 2,000 IU of vitamin D are 8X less likely to get Type 1 diabetes
- Obese people get less sun / Vitamin D - and also vitamin D gets lost in fat
- Sedentary people get less sun / Vitamin D
- Worldwide Diabetes increase has been concurrent with vitamin D decrease and air conditioning
- Elderly get 4X less vitamin D from the same amount of sun
Elderly also spend less time outdoors and have more clothes on - All items in category Diabetes and Vitamin D
553 items: both Type 1 and Type 2 Vitamin D appears to both prevent and treat diabetes
- Appears that >2,000 IU will Prevent
- Appears that >4,000 IU will Treat , but not cure
- 90% less T2 Diabetes in the group having lots of Vitamin D
- Appears that Magnesium helps both Prevention and Treatment
- Many diabetics would be better treated if Gut-Friendly Vitamin D were used
