Does Vitamin D Help With Weight Loss?

Vitamin D has many potential health benefits. This vitamin is a crucial nutrient that our bodies need for many important functions. One of its most important key roles is keeping our bones strong by helping our bodies absorb calcium from the food we eat or the sunshine we get.

This vitamin may also support our immune system, helping us fight off illnesses and infections. It’s also involved in muscle function, can help to improve mood and mental health, and may even aid in weight loss.

Vitamin D can be known as the sunshine vitamin because our bodies can make this vitamin when our skin is exposed to sunlight. When we do not get enough sunlight or nutrient rich foods, that’s where these vitamin supplements can help. It fills in the gaps to ensure we get the right amount for optimal health.

The Natural Barrier Support supplements with The Roots Brand can help you get all the benefits of vitamin D, while providing you with a blend of other nutrients for overall health.

What is Vitamin D?

Vitamin D is a fat-soluble vitamin that you can get in vitamin D rich foods, through supplements, or produced by your body from sun exposure. Vitamin D is a nutrient that is needed for bone health. It also supports brain cell activity, immune system health, and muscle function.

The majority of vitamin D is gained through sun exposure, which allows the body to naturally produce this vitamin. However, there are a few vitamin D rich foods like:

  • egg yolks
  • fatty fish
  • cheese
  • mushrooms
  • beef liver
  • fortified milk

Vitamin D is best known for its role in calcium absorption, which is critical for the development and maintenance of teeth and bone health and strong and healthy muscles. If you don’t get enough of this vitamin, you could be at a higher risk for osteoporosis or other bone disorders.

What is the Link Between Vitamin D Deficiency and Obesity?

There seems to be a connection between vitamin D deficiency and body fat mass. There may be a link between low vitamin D levels and a higher body fat percentage and body fat mass. Here are some studies that have shown this association:

Studies from 2003 and 2004 measured the connection between body fat percentage and serum 25-hydroxyvitamin D (25-OHD) in healthy adults. The results showed that adults with a higher body mass index had lower vitamin D levels.

Another study in 2018 researched the effect of vitamin D supplementation on obese and overweight women. After 6 weeks of the overweight and obese women using vitamin D supplements, they showed a decrease in several measures such as, body mass index, body weight, and waist circumference.

The relationship between vitamin D deficiency and obesity is not fully understood. There are several theories as to why low vitamin D levels may be associated with higher body weight. Some of these theories include:

  • Overweight and obese individuals eat less vitamin D rich foods, like egg yolks or fatty fish.
  • Obese individuals may not get enough sun exposure on their skin and may not be absorbing as much of this vitamin from the sun.
  • Vitamin D is fat-soluble, which means it can be stored in the body’s fat tissues. In obese individuals, higher amounts of body fat can hide away more vitamin D, making it less available to the rest of the body.

Regardless of the theories, more research is needed to determine the connection between vitamin D and body weight.

Symptoms of Vitamin D Deficiency

Vitamin D absorption is important for many functions in the body. It helps the body absorb calcium from the food you eat, which is crucial for bone density and health.

Vitamin D has many health benefits and also plays roles in immune system function, reducing inflammation, regulating cell growth, and supporting muscular function. Therefore, a deficiency fat soluble vitamin can have wide-ranging effects on overall health.

Low vitamin D levels are very common, with around 1 billion people worldwide being vitamin D deficient. Low vitamin D status can occur due to a variety of reasons like inadequate dietary intake, not enough sun exposure, and/or not using vitamin D supplements.

Here are some of the symptoms you might experience if you are not getting enough vitamin D intake:


Though fatigue can have many causes, having low vitamin D may be one of the reasons. A decrease in serum vitamin D levels has been associated with feelings of tiredness and fatigue, especially in older adults.

Bone Pain or Achiness

Vitamin D is an essential vitamin for bone health and calcium absorption. Thus, low vitamin D levels can affect bone density and lead to aches and pains in the bones and weakness in the muscles. Those not getting enough vitamin intake may be at a higher risk for lower back and bone pain.


Vitamin D deficiency has been linked to depression, especially in older adults. This may be because it is associated with the synthesis of serotonin – one of the neurotransmitters responsible for several body functions including mood.

Hair Loss

While hair loss can be due to many factors, severe vitamin D deficiency has been linked to hair loss in some cases. Having low vitamin D levels may lead to alopecia areata, which is an autoimmune disorder that causes hair loss.

Muscle Weakness

Low vitamin D levels can affect muscle mass and result in muscle weakness and pain. Those with vitamin D deficiency are at an increased risk of falls due to muscle weakness.

Can Vitamin D Help With Weight Loss?

Whether or not vitamin D can help you lose weight is still being researched and is not yet fully understood. There is some research that has looked at the relationships between vitamin D and weight. What we do know is:

  • Obesity is associated with vitamin D deficiency. People with higher BMIs tend to have lower levels of vitamin D.
  • There are some indications that adequate vitamin D levels might help enhance the effectiveness of weight loss efforts, particularly when combined with calcium. Some studies suggest that people who have higher levels of vitamin D before they start a weight loss plan lose more weight than those with lower levels. However, it’s not clear whether this is a cause-and-effect relationship. It might be that people who have healthier lifestyles in general are more likely to have adequate vitamin D levels.
  • In terms of a vitamin D supplement, some research suggests that taking vitamin D supplements could aid weight loss or fat reduction, particularly in people who are deficient. However, the results are mixed, and more research is needed to clarify this relationship.

How Does Vitamin D Aid Weight Loss?

Vitamin D and weight loss is a subject that continues to need research. There is conflicting evidence as to whether increasing vitamin D levels can help you lose weight. But there are some studies that show the ways that more vitamin D intake could aid in weight loss:

  1. 2008 study has shown that Vitamin D may potentially reduce the formation of new body fat cells in the body.
  2. Vitamin D seems to suppress the storage of fat cells, which makes it more difficult for new fat cells to form in your body. This effectively reduces fat accumulation.
  3. Vitamin D seems to also be associated with serotonin production and serotonin has been associated with controlling your appetite and helping you feel full, which can result in a decrease in body weight.
  4. Vitamin D may be associated with higher levels of testosterone. Testosterone has been known to play a role in body weight and can trigger weight loss.

Does Weight Influence How Much Vitamin D is Needed?

Vitamin D and weight is a tricky topic. It seems that body weight can influence the amount of vitamin D a person needs. Research suggests that individuals with a higher BMI may need higher doses of vitamin D supplementation to achieve the same blood levels as those with lower BMIs.

The reason for this may be due to how vitamin D is stored and utilized in the body. Vitamin D is fat-soluble, which means it’s stored in fat tissue. In people with a higher amount of body fat, more vitamin D can be taken up and stored by fat tissue, which may reduce the amount of vitamin D available for use by the rest of the body.

For this reason, obese and overweight people are often found to have lower levels of vitamin D in their blood and may require higher vitamin D levels to reach and maintain adequate levels. However, the optimal dose can vary widely depending on individual factors, such as age, geographical location and sun exposure.

Benefits of Taking a Vitamin D Supplement

Vitamin D supplements have a variety of health benefits, especially for those who may have difficulty obtaining sufficient vitamin D through sunlight exposure or diet. Here are some of the benefits of taking a vitamin D supplement:

Supports the Immune and Nervous System

Vitamin D is important for immune and nervous system function. It helps to fight off infection by regulating the activity of immune cells which elicit antiviral responses

Regulates Insulin Levels

There has been some research showing that low vitamin D may be associated with an increased risk of Type 2 diabetes. Thus, higher vitamin D levels can help lower the risk of insulin resistance. One reason may be because insulin is produced by the beta cells of the pancreas.

Vitamin D receptors are present on these cells, and vitamin D is believed to play a role in their function and insulin secretion. If there isn’t enough vitamin D available, this could disrupt normal insulin production.

Helps Lung Function and Heart Health

Vitamin D has been shown to help with the immune responses in chronic respiratory diseases by restricting viral and bacterial colonization in the lungs. For the heart, it is believed to help manage blood pressure and improves the lining of blood vessel walls which allows for improved blood flow. This healthy blood flow can help lower the risk of cardiovascular disease.

Is Vitamin D Supplementation Useful for Weight Loss?

While vitamin D supplements has many benefits, losing weight is one that continues to need more research. So the answer to the question, “can vitamin D help you lose weight” can vary depending on a variety of factors, including age, body size, whether or not you have low vitamin D levels, etc.

Those who are obese and overweight seem to already have low vitamin D. While the reason for these low vitamin D levels is not exactly understood, it may have to do with more weight and body size. So getting enough of this vitamin might contribute to losing weight and body size by reducing fat accumulation and the formation of new fat cells.

Thus, vitamin D supplements may help reduce body fat caused by poor weight management. Those experiencing weight gain may benefit from making sure they are getting enough vitamin D. But it’s important not to use too much due to the risk of toxicity. For the best results, contact a medical professional and take the supplements as prescribed.


Vitamin D is an essential nutrient that plays numerous roles in maintaining our overall health. It aids in the absorption of calcium for strong bones, supports our immune system to help us ward off illnesses, and potentially contributes to heart and lung health. It may also play a role in weight loss.

While the relationship between vitamin D and weight loss isn’t entirely clear, adequate levels of this vitamin could enhance the effectiveness of a weight loss regimen. However, they are not a magic solution for weight loss and should be used in combination with a balanced diet and regular physical activity.
