Vitamin D is essential for strong bones as it helps in calcium absorption from food. Vitamin D deficiency has long been associated with rickets, a bone disease in children. It causes bone pain, slow growth, and brittle bones that can result in deformities. However, studies increasingly demonstrate the essential role of vitamin D in preventing various health problems. According to a study published in 2018, approximately 40% of Americans are vitamin D deficient. It has even been described as a global health problem and "An Ignored Epidemic".


Symptoms such as muscle weakness and bone pain may indicate vitamin D deficiency. Many people, however, experience just minor symptoms. Even if you don't have any symptoms, not getting enough vitamin D can harm your health.


The most effective way for determining the vitamin D level in the body is the 25-hydroxy vitamin D test. For healthy individuals, a 20–50 nanograms/milliliter level is deemed sufficient. But if the level is less than 12 nanograms/milliliter, it shows that you are Vitamin D deficient.


There following are simple ways to increase your vitamin D levels significantly:


Expose yourself to the sun to get adequate vitamin D. When UVB rays from the sun strike your skin, they trigger a chemical process that leads to vitamin D production. Although the quantity of sun required to produce sufficient vitamin D varies, research suggests that to maintain enough vitamin D levels:

  • Try to spend at least 5 to 30 minutes in the sun between 10 a.m. to 4 p.m. every day or twice-weekly.

  • Let your face, arms, legs, and hands be exposed to the sun for this short period of time without using sunscreen.

For this process to work, direct sunlight is required—windows, clouds, smog, clothing, and sunscreen can block or reduce your skin's ability to absorb UVB rays.

Additionally, if you have darker skin, you may need to stay longer in the sun to get the same vitamin D level as those with lighter skin tones. People who have fair skin or are less than 50 convert sunlight into vitamin D much more proficiently than those who have darker skin or are greater than 50. Once the sun's rays strike your skin and trigger the formation of a vitamin D precursor, it takes around eight hours for this forerunner to be transformed to vitamin D3. Vitamin D obtained from the sun has been shown to stay longer in the body than vitamin D obtained from diet or supplements.


Although your body produces vitamin D in response to sunlight, you also require it through your diet. Therefore, increase your diet of vitamin D enrich foods if you wish to boost your vitamin D levels. The following foods may help you increase your vitamin D levels:

  • Cod liver oil

  • Swordfish

  • Salmon

  • Sardines

  • Mushrooms

  • Egg yolk

  • Beef liver

  • Cheese

  • Fortified cereals

  • Fortified Tofu

  • Vitamin D-fortified dairy products,

  • Vitamin D-fortified orange juice

Fish liver oils and fatty fish flesh are two of the greatest vitamin D sources, while egg yolks, beef liver, and cheese have smaller amounts. Mushrooms are the sole vegetarian source of vitamin D. Egg yolk is an easy-to-incorporate vitamin D source.


Supplements may be the simplest and most effective way to boost vitamin D levels. Because of the risk of skin cancer linked with using sunlight to increase vitamin D levels and the difficulty in obtaining adequate vitamin D through diet, supplements are frequently the first line of defense for vitamin D deficient persons. Several multivitamin supplements contain vitamin D, but it is also available as a standalone supplement.

Vitamin D exists in two primary biological forms D2 and D3. D2 is often derived from plants, while D3 is derived from animals. In a 2017 study, D3 is substantially more beneficial than D2 at maintaining and increasing overall vitamin D levels, so look for the supplements that contain this type. A daily dose of 1,000-4,000 IU is considered safe for maintaining healthy levels for most people. However, in other cases— particularly if your present levels are really low or you have inadequate exposure to sunlight — you may require a considerably higher dose.

It's best to consult your doctor before taking supplements to ensure that you're taking the correct dosage. It's also critical to get high-quality supplements that have undergone independent testing.


UV-B-emitting lamps can also help you get more vitamin D, albeit they can be expensive. Your skin can produce vitamin D on its own when exposed to radiation from the sun. UV lamps imitate the sun's action and could be especially beneficial if your exposure to the sun is limited owing to location or time spent indoors.

UV radiation has long been used to treat various skin problems, but it has only recently been promoted as a technique to increase vitamin D levels. However, safety is a major concern with these devices since excessive exposure might result in skin burns. So it is suggested to limit the exposure to 15 minutes at one time.

It is important to note that vitamin D is an essential nutrient. If a test shows that you are vitamin D deficient, you should visit a doctor to determine the right amount of vitamin D you should take to raise and maintain your levels.
