New research on humans shows that daily vitamin D3 supplements can help lower body fat. Obese subjects showed significant improvements in body fat levels.
A new study shows that supplementing with 1000 IU (International Units) of vitamin D3 per day lowers body fat in overweight and obese women who were otherwise healthy.
The randomized study was conducted by Amin Salehpour of the Department of Nutrition, School of Public Health, at Tehran University of Medical Sciences, in Tehran, Iran, and by Farhad Hosseinpanah at the Obesity Research Center, Research Institute for Endocrine Sciences, Shahid Beheshti University of Medical Sciences, in Tehran, Iran, and their colleagues.
Researchers divided a group of 77 women into two groups, and gave one group 1000 IU of vitamin D per day, and gave the other group a placebo, for 12 weeks. After 12 weeks, those who used vitamin D had a statistically significant decrease in body fat, compared to those on placebo. Vitamin D supplement use produced a seven percent reduction in fat mass. The study was published in the Nutrition Journal.
Recent research also shows that low serum vitamin D concentrations are common in obese or overweight humans, and that not having enough vitamin D is linked to greater abdominal obesity.
Vitamin D3 is an important supplement that everyone should consider using, as it provides beneficial effects on body fat levels and metabolic health. You can only know if you have proper levels of vitamin D by having your blood tested. The correct amount you would need to supplement with will depend on blood tests. For proper absorption, you must use it with a fatty meal.
