How to Get Vitamin D: The Sun, Other Sources, and Benefits

Vitamin D Sun, Other Sources and Its Benefits: بسم الله الرحمن الرحيم

Vitamin D we often call “the sunshine vitamin”. It is one of the most powerful nutrients you all know. Moreover, it has significant effects on our overall health. Our skin indeed creates vitamin D under sunlight conditions. It has many more hidden dimensions beyond those apparent in its name alone.

Here I will discuss How you can get vitamin D from the sun, what are its other best sources, and what are the benefits, and signs of its deficiency. And the many ways it enhances your good health.

You can get vitamin D from the sunshine, your food, and supplementation as needed.

How to Get Vitamin D From the Sun


Sunlight is the most natural and a major source of vitamin D. It is possible to make vitamin D when you expose your skin to UVB rays from the sun. To ensure enough vitamin D from sunlight, I usually advise spending 10-30 minutes in the sun several times each week. Focus on the chest, arms, and legs during sun exposure for optimal production.

Other Sources of Vitamin D

Here are some best food sources.

Fatty Fish

High-fat marine fishes (such as salmon and tuna) provide abundant natural vitamin D.

Some excellent choices include:

  • Salmon
  • Mackerel
  • Tuna
  • Sardines
  • Trout

Fortified Foods

Common fortified foods include:

  • Milk
  • Breakfast cereals
  • Orange juice
  • Plant milk substitutes (e.g. Convert to almond milk, convert to soy milk, etc.).
  • Yogurt
  • Margarine
  • Tofu

Make sure you read the label to see how much Vitamin D is in the cream.


Some varieties of mushrooms like Cordyceps, Shiitake or Portobello have low quantities of Vitamin D. Exposure to UV radiation can increase it. Similar to the synthesis of vitamin D by human skin after exposure to sunlight.

Egg Yolks

Egg yolks are another source of vitamin D but in small quantities. One large egg yolk has around 20 IU (IU).

Beef Liver

Beef liver is an excellent source of Vitamin D (about 50iu per 3oz serving).

Cod Liver Oil

Cod liver oil is a true Vitamin D superstar. One tablespoon of cod liver oil contains around 1360 IU. Don’t overdo it on the cod liver oil supplements — too much can cause vitamin D toxicity.


If you can’t get enough of the “sunshine vitamin” naturally. If you have health issues that prevent absorption of the nutrient, your doctor may suggest supplements. Take them based on the doctor’s advice for accurate dosages.
These sources can certainly aid in keeping vitamin D levels, nonetheless, it is essential to balance out. Taking high doses of supplements is dangerous. You should check in with a doctor about your levels of vitamin D and what dosage you should be taking.

There is no one-size-fits-all daily recommended dosage for Vitamin D based on factors. Such as age group, gender, and the degree of skin type. How they live, where they live (latitude), and sun exposure among others. The recommended Dietary Allowance (RDA), as established by health authorities. This is often expressed in terms of International Units (IU) or micrograms (mcg). 

Here are the general guidelines for vitamin D intake:

Infants (0-12 months): The average recommended daily dose for children under one year old is often in the range of 400 – 1000 IU per day. Breastfed infants may need vitamin D supplementation as breast milk is often insufficient in providing sufficient amounts of the nutrient.

Children (1-18 years): Kids and teenagers usually require between 600-1000 IU (15-25 mcg) of Vitamin D per day. Vitamin D needs to be in their growing bodies and overall well-being.

Adults (19-70 years): Most adults between the ages of 18 and 70 need at least 600-800 IU of vitamin D each day. The 0.8 gram/day dose was used in the studies. That was found to be an adequate level for preserving bone health and overall wellness.

Adults (over 70 years): Older seniors, especially over the age of 70+, might need somewhat greater daily. This level of vitamin D insufficiency is usually resolved by the suggestion of 800-1000 IU/day. This is a supplementation plan for those over the age of 70 years aimed towards reducing age-associate.

Pregnant and Breastfeeding Women: Pregnant and nursing mothers — 600-800 IU (15-20 mcg) per day. Vitamin D supplement during pregnancy and lactation is important for both maternal and neonatal health.

Important Things about Vitamin D Dosage

Vitamin D is one of the four fat-soluble Vitamins. Which means that the body can store it and liberate it slowly. This means you don’t need sunlight every day. The Vitamin D that your body makes and stores in the summer. They can be liberating slowly over a couple of months, to get you through winter. Some people who are at high risk of its deficiency may benefit from taking its supplements. Especially older people who are at risk of fractures. People who are naturally very dark-skinned and live in less sunny climates. Those who spend long hours indoors, and women that are already Vitamin D deficient and are pregnant.

If you think you or a family member are at risk of Vitamin D deficiency. Do consult with your doctor to see if a supplement may help you. It is a fat-soluble vitamin; your body can’t eliminate it if you take too much. Vitamin D from sunlight can’t reach toxic levels. But Vitamin D from supplements can, especially if taken in very large doses.

You should be especially careful with children. They have small bodies and if they are given too much Vitamin D through supplements, it may become toxic. There have been cases of children who suffered from a condition called hypercalcemia. Because of surplus Vitamin D given by their parents.

Remember to talk to your pharmacist before you give your children any kind of Vitamin D supplement. It’s always best to consult with your doctor to determine the appropriate amount of vitamin D for your specific needs.

How can I Check my Vitamin D Levels?

The most accurate method of determining how much vitamin D you have in your system. The gold standard is to conduct the 25-hydroxyvitamin D blood test. This test measures the amount of vitamin D in your blood; it may help identify whether or not you’re deficient.
If you’re worried you don’t have enough of the stuff in your body, your GP might suggest having a blood test. The physician can order the study and guide on reading its results.
This is a point I’ll keep emphasizing. Some doctors won’t even check your vitamin D level unless you’re showing symptoms of deficiency or they have a particular reason to. However, if you feel like a risk for low levels of Vitamin D, the benefits aren’t even worth it.
in case of deficiency, you should consider talking to your doctor for a serum 25-hydroxy vitamin D (total) test.


It’s easy to get deficient in vitamin D. You can’t synthesize it with UV-A and UV-B rays from the sun. This is at an intensity high enough (for a significant period) and food doesn’t supply enough of it either.
Therefore, it’s better to consult a doctor about taking a vitamin D pill.
If you’re curious about your vitamin D status, a blood test can reveal whether you’re deficient. Which might mean supplementation is required to bring levels back to normal. By making efforts such as the above, you could guarantee your body’s needs of fulfillment and maintaining health.
