Vitamin D and Weight Management
A nutrient often low in people with obesity, important to check and correct during a weight loss journey.
Plain English
Patient-Friendly Explanation
Vitamin D is a nutrient your body makes from sunlight and gets from certain foods. Research shows people with obesity often have lower vitamin D levels, and low levels may be linked to weight gain and metabolic problems. Checking and correcting your vitamin D can support your overall health during weight loss.
Medical
Clinical Definition
Vitamin D is a fat-soluble secosteroid hormone involved in calcium homeostasis, immune function and metabolic regulation. Obesity is associated with lower circulating 25-hydroxyvitamin D, partly because the fat-soluble vitamin is sequestered in adipose tissue. While observational studies link vitamin D deficiency to obesity and insulin resistance, interventional trials have not consistently shown that supplementation alone produces weight loss.
