Vitamin D is an essential nutrient that has many important roles within our bodies. It helps us absorb calcium, strengthen bones, and regulate our immune systems. It is also known for its role in protecting us from certain diseases and illnesses.
How does Vitamin D Work? Vitamin D is created from the ultraviolet beams of the sun on our skin. Our bodies convert it into a hormone that helps us utilize the calcium that we take in from food. This helps to keep our bones strong, and our teeth healthy. Vitamin D also helps regulate the production of T-cells, which are important to the function of our immune systems.

- Supplements – if you can’t get enough vitamin D from the food you eat and sun exposure then you may want to consider a vitamin D supplement.
What are the Benefits of Vitamin D? Vitamin D is incredibly important for our immune systems, as it helps us produce the white blood cells that are needed to fight off infection. It is also essential for our bones and teeth, as it helps our bodies absorb calcium and ensure that our bones stay healthy. In addition, it has been linked to a reduced risk of certain diseases such as diabetes, heart disease, and certain types of cancers.
How Much Vitamin D Do I Need? The exact amount of vitamin D an individual needs will vary based on age and health, but in general it is recommended that adults get 600-800IU of vitamin D per day. It is a good idea to discuss this with your doctor to make sure you are getting the right amount.

Vitamin D helps to ensure that the body’s natural immune response is neither too weak nor too aggressive.
The health benefits of Vitamin D are numerous. Not only does it boost the immune system, but it also increases the absorption of calcium, phosphorus, and magnesium.

Furthermore, a can also lead to rickets, a condition that affects the development of children’s bones, teeth, and tissues.
Ensuring sufficient Vitamin D intake is particularly important during the winter months when the sun may be blocked by clouds and the intensity of its UV rays is weaker. Taking a Vitamin D supplement during these times can help to replenish Vitamin D levels in the body. This, in turn, helps to prevent a deficiency and maintain the integrity of the immune system.
