Vitamin A: Its Benefits and Sources

Sources of Vitamin D:

While the body can synthesize vitamin D through exposure to sunlight, it can also be obtained through certain foods and supplements. Here are the top 7 sources.

  1. Sunlight: The most natural and efficient way to get this vitamin is through exposure to sunlight. Your skin can synthesize vitamins when exposed to ultraviolet B (UVB) rays from sunlight. However, the amount of vitamin D your skin can produce depends on various factors such as your skin type, location, time of day, season, and amount of skin exposed.
  2. Fatty fish: Fatty fish such as salmon, tuna, and mackerel are excellent sources of it. A 3-ounce serving of cooked salmon contains about 447 IU of this vitamin, which is over 100% of the recommended daily intake for adults.
  3. Fortified dairy products: Many dairy products such as milk, yoghurt, and cheese are fortified with vitamin D. One cup of fortified milk contains about 120 IU of it.
  4. Egg yolks: Egg yolks are another good source of it. One large egg yolk contains about 37 IU of this vitamin.
  5. Mushrooms: Some mushrooms are also a natural source of it, especially those that have been exposed to UV light during growth. One cup of sliced, raw, white mushrooms contains about 9 IU of vitamin D.
  6. Cod liver oil: Cod liver oil is a supplement that is high in vitamin D. One teaspoon of cod liver oil contains about 450 IU.
  7. Supplements: Supplements are widely available and can be an easy way to ensure adequate vitamin D intake. It is important to speak with your healthcare provider before starting any supplement regimen to determine the appropriate dosage and ensure it does not interact with any medications or medical conditions.

Vitamin D Deficiency:

Despite the importance of vitamin D, many people are deficient in this nutrient. Factors such as age, skin colour, and geographic location can affect its levels. Symptoms of its deficiency may include muscle weakness, bone pain, and fatigue.


 It is an essential nutrient that plays a critical role in many aspects of health. Maintaining adequate vitamin D levels through sun exposure, diet, and supplementation can help to prevent a range of health problems and promote overall well-being. If you suspect that you may be deficient, speak with your healthcare provider to determine the best course of action.
