Understanding Vitamin D
Vitamin D, a fat-soluble vitamin, helps the body enhance calcium and phosphate absorption, maintaining bone and teeth health. It also plays a vital role in various physiological processes. Under the influence of sunlight, the body can synthesize Vitamin D, with two crucial structures known as Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol).

Eggs are a nutritious food containing abundant protein, fats, vitamins, and minerals. However, vitamin D is mainly found in the egg yolk. A regular egg yolk from a farm-raised chicken can provide between 18 – 39 IU of vitamin D. However, the vitamin D content in eggs also depends on the source and diet of the chicken.
Free-range chickens exposed to natural sunlight lay eggs with more vitamin D than chickens raised in greenhouses. Chickens fed with vitamin D-rich feed can produce eggs with up to 6,000 IU of vitamin D per egg yolk. This is an effective and safe vitamin D supplement for those who do not consume fish or seafood.
However, it's important to note that vitamin D can lead to toxicity if over-supplemented. Therefore, it's advisable not to consume too many eggs per day and instead combine them with other foods to provide sufficient other vitamins and minerals for the body.

Mushrooms are the only plant source that can provide vitamin D. They have the ability to synthesize vitamin D when exposed to UV rays from sunlight, similar to humans. However, mushrooms differ from animals in that they synthesize vitamin D2, while animals synthesize vitamin D3. Studies show that vitamin D3 can effectively increase vitamin D concentration in the blood compared to vitamin D2. The amount of vitamin D in 100 grams of mushrooms is approximately 2300 IU.

After knowing which foods contain vitamin D, consider the following when consuming them:
- Diversify your diet: Foods rich in vitamin D not only supplement the vitamin but also provide various other nutrients beneficial for the body. However, combine them with vegetables, fruits, grains, and legumes to avoid deficiencies in other vitamins and minerals.
- Pay attention to the necessary vitamin D amount for the body: Each person's vitamin D needs vary depending on age, health status, and lifestyle. Avoid over-supplementing vitamin D as it may lead to side effects such as nausea, vomiting, headaches, yellow or itchy skin. If there's a risk of vitamin D deficiency due to age, illness, or diet, consult a doctor for appropriate vitamin D supplementation.
- Properly process and store food: Foods rich in vitamin D may lose some of their content during improper processing or storage. Consume fresh seafood or cook at moderate temperatures to preserve vitamin D. Store vitamin D-rich foods in the refrigerator or an airtight container to avoid exposure to light and air.
