The Importance of Having the Right Vitamin D Intake

Vitamin D is an essential nutrient that plays a crucial role in maintaining good health. It is a fat-soluble vitamin that is naturally found in very few foods, but it can also be obtained through exposure to sunlight and supplementation.

42% of Americans don’t get enough vitamin D. If you’re an outdoorsy person with a warm, sunny climate, getting your vitamin D naturally may be easier than those who stay indoors or who don’t get much sun where they live. Those in warmer climates might need to invest in a bug screen for doors if they’re going to be coming and going a lot and want to keep air flowing through their home.

Let’s take a closer look at why having the right vitamin D intake is essential.

Stronger Bones

One of the primary roles of vitamin D is to help the body absorb calcium from the intestines. This is essential for maintaining healthy bones and teeth, as well as preventing conditions like osteoporosis and fractures. Vitamin D also helps to regulate the levels of calcium and phosphorus in the blood, which are important for overall health.

Immune System

Vitamin D has also been shown to have immune system benefits. Studies have found that vitamin D deficiency is associated with an increased risk of infectious diseases, including respiratory tract infections, such as the flu and pneumonia. This is because vitamin D plays a role in activating the immune system and producing antimicrobial peptides that can help fight off infection.

Helping with chronic conditions

In addition to its effects on bone health and the immune system, vitamin D has been shown to have a role in preventing and managing certain chronic conditions. For example, research suggests that vitamin D may help reduce the risk of certain types of cancer, including breast, colon, and prostate cancer. Vitamin D may also help to lower the risk of type 2 diabetes, cardiovascular disease, and autoimmune diseases like multiple sclerosis and rheumatoid arthritis.

Risk Groups

Getting the right amount of vitamin D is important for everyone, but certain groups may be at higher risk for deficiency. People who live in northern latitudes, where there is less sun exposure, and people with darker skin, which makes it more difficult to absorb vitamin D from sunlight, may be at higher risk for deficiency. People who are obese, have certain medical conditions that affect the absorption of vitamin D, or take certain medications may also be at risk for deficiency.


The recommended daily intake of vitamin D varies depending on age, sex, and other factors, but the general guideline for vitamin D supplements for adults is 600-800 IU per day. However, some experts believe that this may not be enough for optimal health and recommend higher amounts, up to 2000 IU per day.

Vitamin D Naturally

  • Sun

There are a few natural ways to increase your vitamin D intake. The most obvious is through sunlight exposure. Vitamin D is produced in the skin when it is exposed to UVB rays from the sun. However, it is important to balance sun exposure with the risk of skin damage from too much UV radiation. A good rule of thumb is to aim for 10-15 minutes of sun exposure on the arms, legs, and face two to three times per week, without sunscreen, during peak hours when the sun is at its highest.

  • Diet

Diet is another natural source of vitamin D. Fatty fish like salmon, tuna, and mackerel are some of the best sources of vitamin D. Other foods like egg yolks, cheese, and fortified dairy and grain products can also contribute to your vitamin D intake. It is important to note that most foods do not contain enough vitamin D to meet daily intake requirements, so dietary sources should be combined with other sources like sunlight and supplementation.

Mushrooms are another source of vitamin D, but only when they have been exposed to UV light. Some commercial varieties of mushrooms are grown under UV light and can provide a source of vitamin D. Additionally, some types of mushrooms can be placed in the sun for a few hours before eating to increase their vitamin D content.


Vitamin D is an essential nutrient that plays a crucial role in maintaining good health. It is vital for bone health, immune system function, and the prevention of chronic diseases. Getting the right amount of vitamin D through diet, sunlight, and supplementation can help to ensure optimal health and well-being.

It’s essential to eat a healthy diet that includes vitamin D-rich foods like fatty fish, egg yolks, and fortified dairy products. However, it can be difficult to get enough vitamin D through diet and sunlight alone, especially for those at higher risk for deficiency. In these cases, vitamin D supplementation may be necessary to meet recommended intake levels.
