Weight gain in older women

According to a new study funded by the National Institutes of Health and published in the Journal of Women’s Health, more than 4,600 women with age 65 years and older shows that having low Vitamin D levels can lead to mild weight gain. Previous research has already showed that obese people are more inclined to have low Vitamin D levels.

On the other hand, there have been randomized controlled trials that have shown a very modest weight loss after taking Vitamin D supplements.
