The debate is still being carried out among scientists on whether vitamin D supplements could help slow down type 2 diabetes or even treat it. A new study on the matter is showing positive results by analyzing several people with this diagnosis. The patients have been treated with a vitamin D supplement.
The Center for Disease Control and Prevention or the CDC has announced that type 2 diabetes and its precursor is affecting more than 100 million people in the US. Prediabetes is described by higher than normal glucose levels that lead to an increased risk in developing the disease.
Forty percent of adults US citizens are reported to be vitamin D deficient. This has been associated with reduced insulin sensitivity, which means that insulin cannot be used appropriately to regulate glucose levels in the bloodstream.
Varied results with vitamin D and type 2 diabetes
Vitamin D deficiency is linked with type 2 diabetes, but some trials and studies do not confirm this. Different studies have found that: “Replenishment with a large dose of vitamin D-3 to [people] with [type 2 diabetes] and vitamin D deficiency did not change insulin sensitivity or insulin secretion.”
Quite a few researchers have reached similar results, but all of these trials have been performed on patients that have been affected by the disease for a long time, as well as having a short duration of only a couple of weeks.
A more recent study is taking more time to research the effects of a vitamin D supplement. This is being done to both prevent the disease as well as try to treat it.
Extensive study with vitamin D treatment
Many factors have been taken into consideration for this research trial. These include insulin sensitivity, insulin secretion, blood pressure, and beta-cell function.
The study took place in Quebec, Canada. It was double-blind as well as placebo-controlled and had 96 subjects. The participants were under medication for diabetes but did not have a vitamin D supplement intake during prior months.
Half of the subjects were given 5-10 times the recommended dose of vitamin D3 daily for six months. The other half received placebo capsules. The results of the 6-month trial study showed that increased vitamin D supplementation significantly improved insulin sensitivity as well as beta-cell function. Newly diagnosed individuals saw the most favorable results. But those with the lowest insulin sensitivity showed the most significant increase in terms of efficiency.
