Health benefits of Vitamin D Example
Getting enough vitamin D helps the growth and development of bones and teeth. It may also provide improved resistance to certain diseases.
Vitamin D is a fat-soluble vitamin in a family of compounds that includes vitamins D1, D2, and D3.
Your body produces vitamin D naturally when it’s directly exposed to sunlight. You can also get vitamin D from certain foods and supplements to ensure adequate levels of the vitamin in your blood.
Getting enough vitamin D is important for typical growth and development of bones and teeth, as well as improved resistance to certain diseases.
Here is more information about the benefits of vitamin D, plus information about downsides, how much you need, and foods with vitamin D.
In addition to its primary benefits, research suggests that vitamin D may also play a role in:
Reducing the risk of multiple sclerosis (MS). A 2018 review of population-based studies found that low levels of vitamin D are linked with an increased risk of MS (
Decreasing the chance of heart disease. Low vitamin D levels have been linked to increased risk of heart diseases such as hypertension, heart failure, and stroke. But it’s unclear whether vitamin D deficiency contributes to heart disease or simply indicates poor health when you have a chronic condition (
Reducing the likelihood of severe illnesses. Although studies are mixed, vitamin D may make severe flu and COVID-19 infections less likely. A recent review found that low vitamin D levels contribute to acute respiratory distress syndrome (

Supporting immune health. People who do not have adequate vitamin D levels might be at increased risk of infections and autoimmune diseases, such as rheumatoid arthritis, type 1 diabetes, and inflammatory bowel disease (
Research has shown that vitamin D might play an important role in regulating mood and decreasing the risk of depression.
A review of 7,534 people found that those experiencing negative emotions who received vitamin D supplements noticed an improvement in symptoms. Vitamin D supplementation may help people with depression who also have a vitamin D deficiency (
People with higher body weights have a greater chance of low vitamin D levels (
In one study, people with obesity who received vitamin D supplements in addition to following a weight loss diet plan lost more weight and fat mass than the members of the placebo group, who only followed the diet plan (
In an older study, people taking daily calcium and vitamin D supplements lost more weight than subjects taking a placebo supplement. The researchers suggest that the extra calcium and vitamin D may have had an appetite-suppressing effect (10).
The current research doesn’t support the idea that vitamin D would cause weight loss, but there appears to be a relationship between vitamin D and weight.
