The British Journal of Nutrition reported about a new trial which suggests that taking Vitamin D supplements may help improve insulin resistance and insulin sensitivity.The head of the study P.R. von Hurst and colleagues of Massey University in Auckland Australia found that in a group of women increasing the average serum level of vitamin D from 21 to 75 nmol/L drastically improved insulin sensitivity and reduced insulin resistance.
The study involved 81 South Asian women aged 23 to 68 years with insulin resistance, homeostasis model assessment 1 greater than 1.93 and serum vitamin d level less than 50 nmol/L.
For the study, 42 subjects were given 100 microg or 4000 IU of vitamin D per day while 39 subjects received a placebo as controls. The randomized, controlled, double-blind trial lasted six months.
Subjects did not take vitamin d supplements if any in a dose of no more 25 microg or 1000 IU/d.
The researchers also found improvement of insulin resistance was maximized when serum vitamin D levels reached or exceed 80 nmol/L. The vitamin D supplementation did not affect insulin secretion.
The recipe to improve your insulin resistance is thus as follows:
Taking vitamin D in a dose of 4000 IU per day for six months.
The target serum level: 80 to 115 nmol/L
People with insulin resistance can produce insulin, but their bodies do not use insulin properly. Insulin resistance boosts the risk of type 2 diabetes mellitus and heart disease.
Vitamin D3 enhances intestinal absorption of calcium and phosphate. It also regulates the circulation of Renin (enzyme) in our blood stream, responsible for the rise of blood pressure. Deficiency of Vitamin D3 has been connected to neurological disorders.
vital for bone health – enables calcium absorption;
acts as an immune system modulator in the body;
help reduce the risk of diabetes, hypertension and heart diseases.
