Poor gut is associated with Gut diseases as well as Diabetes, Multiple Sclerosis, and many other diseases
Reminder - Vitamin D is absorbed in the first portion of the small intestine
Some gut problems which only occur in large intestine may not be a problem

Oral vitamin D supplementation is better than parenteral in improving vitamin D deficiency in individuals with no systemic illness. Our aim was to compare the efficacy of oral and parenteral routes of vitamin D supplementation on circulating serum 25(OH) vitamin D level in patients with type 2 diabetes mellitus.

Total 85 cases of with type 2 diabetes mellitus were screened for vitamin D status of which 71 patients were vitamin D insufficient/deficient. They were randomized into two intent to treat groups with different vitamin D supplementation protocols

  • (a) Oral-60000 IU per day for 5 days (group I; n = 40) and
  • (b) injectable-300000 IU intramuscularly once (group II; n = 31).

Baseline and one-month post supplementation 25(OH) vitamin D levels were measured in both the groups.

Baseline clinical characteristics and 25(OH) vitamin D levels were comparable in both the groups. Post treatment 25(OH) vitamin D level in

  • group I was 26.06 ± 9.06 ng/ml and in
  • group II was 49.69 ± 18.92 ng/ml.

After one month of vitamin D supplementation, increment in 25(OH) vitamin D level from baseline was significantly higher in group II than group I (p < 0.001).

Interpretation & conclusions
Injectable method of supplementation was better than oral route in improving serum 25 (OH) vitamin D status in patients with type 2 diabetes. The study suggested impaired absorption of vitamin D from the gastrointestinal tract in patients with type 2 diabetes mellitus and a need for parenteral route of vitamin D supplementation in deficient patients with type 2 diabetes mellitus.
