Aims: To assess the dietary supplement use in adult individuals with type 1 diabetes, and to study the association between vitamin D supplementation and glycaemic control in an observational cross-sectional study.

Methods: The study subjects were participants of the Finnish Diabetic Nephropathy Study. Data were included from all individuals with type 1 diabetes with estimated glomerular filtration rate ≥60 mL/min/1.73 m2 , who had completed a diet questionnaire. In the questionnaire, the participants reported dietary supplement use for the past 30 days. A thorough investigation with an assessment of the blood panel was conducted at the study visit.

Results: Data were available from 1181 individuals (43% men, mean ± SD age 45 ± 13 years). Altogether 62% of the sample reported supplement use; 56% reported some vitamin or mineral and 27% reported non-vitamin and non-mineral supplement use. Supplement use was more frequent among women and those supplementing had better overall health. In the study sample, of the vitamins and minerals, vitamin D (45%) and magnesium (31%), respectively, were the most frequently reported. In the multivariable models, vitamin D supplementation was associated with better glycaemic control.
Starting from a daily dose of ≥30 μg, there was evidence of improving glycaemic control with higher doses of supplemental vitamin D (e.g., for 30 μg: B [Wald Confidence Internal], p-value, -2.76 [-5.03 to -0.49], 0.017).

Conclusions: Supplement use was frequent in this sample of adult individuals with type 1 diabetes. Due to potential drug-supplement interactions, the attending physicians should be aware of their patients' supplement use. The causality between vitamin D supplementation and glycaemic control should be assessed in a randomized controlled trial.

Note: Finns may have the highest Vitamin D levels on the planet, so do not need much more

After years of adding vitamin D, Finland now has 38 ng levels - March 2022

VitaminDWiki – Overview Diabetes and vitamin D contains

• 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
