Learn about the importance of getting enough vitamin D for overall health. Discover natural and unconventional sources of vitamin D, including diet, sunlight, and supplements. Explore the link between vitamin D and bone health and the risks of vitamin D deficiency, along with ways to get enough of this crucial nutrient.


If you’re concerned about your overall health, you’ve probably heard about the importance of getting enough vitamin D. This essential nutrient is crucial for maintaining healthy bones, supporting the immune system, and even regulating mood. While many people know that vitamin D can be obtained through sun exposure, there are actually several ways to get this vital nutrient. In this article, we’ll explore some of the natural and unconventional sources of vitamin D to help you maintain optimal health.

Top 10 Foods Rich in Vitamin D to Include in Your Diet

One of the best ways to get vitamin D is through food. While it can be challenging to get enough vitamin D from diet alone, incorporating certain foods into your diet can help ensure you’re getting enough. Here are the top 10 foods that are rich in vitamin D:

  • Sockeye salmon – 3 oz: 447 IU/26%DV
  • Sardines – 3 oz (canned in oil or drained) : 154 IU/9%DV
  • Egg yolk – 1 large: 41 IU/2%DV
  • Mushrooms – 1 cup (raw, exposed to UV light): 680 IU/34%DV
  • Fortified cereals – 3/4 cup: 40 IU/2%DV
  • Fortified orange juice – 3/4 cup: 40 IU/2%DV
  • Fortified dairy milks – 1 cup: 115-124 IU/6-10%DV
  • Tuna – 3 oz: 154 IU/9%DV
  • Cod liver oil – 1 tablespoon: 1,360 IU/170%DV
  • Fortified non-dairy milks – varies by brand and type

Unconventional Sources of Vitamin D: An Overview

In addition to food sources, there are several other sources of vitamin D. One common way that vitamin D is added to food is through fortification, which means that extra vitamin D is added to certain foods to boost the overall nutrient content. Some examples of fortified foods include:

  • Fortified cow’s milk
  • Fortified almond, soy, and other non-dairy milks
  • Fortified orange juice
  • Fortified breakfast cereals
  • Fortified margarine or other spreads

In addition to fortification, there are some natural and unconventional food sources that contain vitamin D. For example, mushrooms contain vitamin D when exposed to ultraviolet light, and some types of fish eggs are also rich in vitamin D. Other sources of vitamin D include:

  • Cod liver oil
  • Fatty fish like salmon and mackerel
  • Egg yolks
  • Butter made from grass-fed cows
  • Liver from beef, pork, or chicken

The Link Between Vitamin D and Sun Exposure: Exploring the Science

Sun exposure is one of the primary ways that our bodies generate vitamin D. When the skin is exposed to sunlight, it produces a type of cholesterol called 7-dehydrocholesterol. This compound is then converted into vitamin D3 (also known as cholecalciferol) in the liver and kidneys.

However, not all sunlight exposure is equal when it comes to vitamin D production. The amount of vitamin D your body synthesizes depends on several factors, including:

  • Time of day – vitamin D is most efficiently produced when the skin is exposed to sunlight between 10 am and 3 pm
  • Latitude – people who live closer to the equator receive more intense sun exposure year-round, which means they can make more vitamin D in their skin
  • Skin color – people with darker skin need more sun exposure to produce the same amount of vitamin D as lighter-skinned individuals because melanin (the pigment that gives skin its color) reduces the skin’s ability to produce vitamin D
  • Age – as we get older, our skin becomes less efficient at producing vitamin D

So how much sun exposure is necessary? According to the Vitamin D Council, fair-skinned people can produce enough vitamin D with just 10-20 minutes of sun exposure on their face, arms, and legs, a few times per week. However, people with darker skin may need up to six times as much sun exposure to produce the same amount of vitamin D.

Vitamin D Supplements vs. Natural Sources: Which is Better for You?

While getting vitamin D from natural food sources and sunlight is the most efficient way for your body to produce this nutrient, there are some circumstances in which vitamin D supplements may be beneficial. For example, people with limited sun exposure, those with digestive issues that affect their ability to absorb nutrients, and older adults may benefit from taking a vitamin D supplement.

While there are many different types of vitamin D supplements, the two most common forms are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D3 is the form of vitamin D that is produced in the skin, so it’s thought to be more effective at raising blood levels of the nutrient than vitamin D2.

When deciding whether to take a vitamin D supplement, it’s important to consider the potential risks and benefits. While vitamin D toxicity is rare, it’s still important to follow recommended dosages and talk to your doctor about any supplements you’re considering taking.

The Importance of Vitamin D for Bone Health: What You Need to Know

Vitamin D is essential for bone health because it helps the body absorb calcium from food. Without enough vitamin D, your body is unable to effectively use calcium, which can lead to weaker bones and an increased risk of fractures. In fact, severe vitamin D deficiency can lead to a condition called osteomalacia, which causes softening of the bones and can result in bone pain, muscle weakness, and difficulty walking.

Additionally, research has linked vitamin D deficiency to a higher risk of osteoporosis, a condition in which bones become less dense and more prone to fractures. By getting enough vitamin D through diet or sunlight, you can help support strong and healthy bones.

Vitamin D Deficiency: Causes, Symptoms, and How to Get Enough

Despite the importance of vitamin D, many people don’t get enough of this essential nutrient. Some common causes of vitamin D deficiency include:

  • Spending little time outside
  • Wearing clothing that covers most of the skin
  • Living in a region with little sunlight, especially during the winter months
  • Having dark skin
  • Being overweight
  • Having a condition that affects the ability to absorb nutrients, like celiac disease or inflammatory bowel disease
  • Following a strict vegan diet

If you’re not getting enough vitamin D, you may experience symptoms like fatigue, muscle weakness, bone pain, or frequent infections. To ensure that you’re meeting your daily needs, consider incorporating vitamin D-rich foods into your diet and spending a few minutes in the sun each day.


Vitamin D is a crucial nutrient for overall health, supporting bone health, immune function, and more. While sunlight exposure is the primary way that our bodies produce vitamin D, there are several natural and unconventional sources of this vitamin, including fatty fish, egg yolks, and fortified foods. By making an effort to include vitamin D-rich foods in your diet and spending a few minutes in the sun each day, you can help ensure that you’re getting enough of this important nutrient.
