Many people ask: does vitamin D help with weight loss?
Let’s explore the science, potential benefits, and how vitamin D may — or may not — affect your weight loss journey.
What Is Vitamin D?
Known as the “sunshine vitamin,” it plays a key role in many bodily functions.
It helps with:
- Calcium absorption
- Helps defend against infections
- Linked to serotonin and depression
- Contributes to physical performance
What the Research Says
Several studies have found links between low vitamin D levels and higher body weight.
Some research suggests:
- Vitamin D may influence fat metabolism
- Chronic inflammation is tied to weight gain
- Helps people stay consistent with workouts
- Can help manage blood sugar and appetite
Studies That Support the Link
- 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.

People most likely to benefit from vitamin D supplementation include:
- Those who are deficient or low in vitamin D
- Vitamin D may support improved hormone function
