Vitamin D3 May Reduce Inflammation in Overweight Women
Inflammation is common in individuals who are overweight or obese and has been linked with higher risk of chronic disease. A recent study suggests that sticking to a regimen of daily vitamin D3 supplements may reduce levels of C-reactive protein (CRP, a marker of chronic inflammation) in obese and overweight women.
Participants in the study included 218 overweight and obese women between the ages of 50 and 75. Over the course of one year they were assigned either 2,000 IU daily of vitamin D3 or a placebo. All of the women were also placed on the same weight loss diet and participated in 225 minutes per week of moderate aerobic activity,
For the 188 women who completed the study, no difference was seen between the vitamin D3 group and the placebo group in terms of weight or fat loss, nor was there any difference in CRP levels.
However, when the researchers looked at just the women who had a 97% compliance rate with the supplement program, they saw that CRP levels were reduced by 46% while the placebo group showed reductions of only 25%.
Researchers from the Fred Hutchinson Cancer Research Center in Seattle conducted the study. It was published online ahead of print on March 12, 2014, in The American Journal of Clinical Nutrition.
Consumption of vitamin D3 has been linked to reducing the risk of osteoporosis and high blood pressure in mature adults, improving kidney health, reducing the risk of skin cancer, improving cardiovascular health, combating diabetes, and improving age related eye degeneration.
Vitamin D can be found in milk, fortified cereals, fish, and eggs. Your body also processes vitamin D from the sun but it becomes harder for our bodies to process vitamin D as we age. This can be a particular problem for people living in the northern hemisphere, where sunlight is scarce for much of the year. A high quality vitamin D3 supplement is always a good option if you feel that you’re not getting enough through diet and sun.
