One of the unique aspects of vitamin D is that it can be produced by your body when your skin is exposed to sunlight. This process is vital, especially for those living in regions with limited sunlight.
Let’s discuss primary sources of vitamin D:
1- Sunlight Exposure and Synthesis
Sunlight is a natural source of Vitamin D. When your skin is exposed to sunlight, specifically ultraviolet B(UVB) rays, it triggers a process in which your skin synthesizes vitamin D. Just 10-15 minutes of sun exposure a few times a week can help your body produce enough of this nutrient.
2- Dietary Sources of Vitamin D (Vitamin D rich foods, Dietary sources of vitamin D)
If you’re not getting enough sun exposure or want to diversify your sources of vitamin D, your sources of vitamin D, your diet can provide a boost. Here are some dietary sources of Vitamin D:
- Fatty Fish: Fatty fish like salmon, mackerel, and trout are excellent sources of vitamin D. Just a single serving can provide a significant portion of your daily needs.
- Fortified Foods: Many foods are fortified with Vitamin D, vitamin C, including milk, orange juice, and cereals.
- Egg Yolks: Egg yolks contain a small amount of vitamin D, so including eggs in your diet can contribute to your intake.
- Dairy products: Some dairy products, such as yogurt and cheese, are also fortified with Vitamin D.
- Mushrooms: Certain types of mushrooms, like shiitake mushrooms, contain Vitamin D, especially when exposed to ultraviolet light. While they may not provide as many sources, they are a good option for vegetarians and vegans.
Supplements: Vitamin D Tablets, Capsules, and Injections
In some cases, dietary sources and sun exposure may not be sufficient to meet your Vitamin D needs. That’s where supplements come in.
Vitamin D supplements, available in tablets, capsules, and injection forms, can be prescribed by a healthcare professional to address deficiencies.
Vitamin D3 vs. D2: Different Forms of Vitamin D
Vitamin D exists in several forms, with the most common being Vitamin D3(cholecalciferol) and Vitamin D2(ergocalciferol). Understanding the differences between these forms is important, as they impact how your body absorbs and utilizes Vitamin D.
Vitamin D3 – Cholecalciferol
Vitamin D3 is the form of Vitamin D that your skin synthesizes when exposed to sunlight. It’s also found in some animal-based food sources, such as fatty fish and egg yolks. Research suggests that Vitamin D3 is more effective at raising and maintaining blood levels of Vitamin D.
When it comes to supplements, Vitamin D3 supplements are widely available in various forms, including tablets and capsules. They are preferred by many healthcare professionals due to their superior bioavailability.
Vitamin D2 – Ergocalciferol
Vitamin D2, on the other hand, is typically found in plant-based sources, such as certain types of mushrooms that have been exposed to UV light. It’s also used in some fortified foods and supplements.
While Vitamin D2 can raise blood levels of Vitamin D, it’s generally considered to be less portent than Vitamin D3. However, it can still be a suitable option for individuals who follow a vegetarian or vegan diet.
