Large fluctuations in glucose (sugar) levels could influence the risk of complications in type 1 diabetes patients. This study, executed by a Brazilian university hospital, aimed to evaluate these fluctuations and insulin needs in type 1 diabetes patients supplemented with vitamin D. 22 study participants received 4000 IU/day (100 µg) and 10000 IU/day (250 µg) of vitamin D3 for 12 weeks and underwent continuous glucose monitoring. The results showed significant correlations between variations in glucose levels, insulin needs, and vitamin D levels, which means that in patients who had better vitamin D levels, insulin needs were significantly lower. In conclusion, this study suggests a relation between vitamin D supplementation, improved glucose fluctuations, lower insulin needs, and lower frequency of too low blood glucose levels (hypoglycemia) in these patients.
