Can Vitamin D Support Fat Loss?

Let’s explore the science, potential benefits, and how vitamin D may — or may not — affect your weight loss journey.

Vitamin D is a fat-soluble vitamin that the body produces when the skin is exposed to sunlight.

Some research suggests:

- Chronic inflammation is tied to weight gain
- Helps people stay consistent with workouts

Scientific Evidence and Limitations

- A study in 2014 found that overweight women who took vitamin D lost more fat than those who didn’t supplement.
- Another review showed vitamin D helped improve metabolic markers related to weight control.
- Some trials show no major impact on weight loss unless deficiency was corrected first.

While promising, the evidence is not yet strong enough to say vitamin D alone causes weight loss.
