Getting enough vitamin D is key for your health. Knowing how to get it from different sources is important. You can do this by eating foods rich in vitamin D, getting sunlight, and taking supplements when needed.
Natural Sources of Vitamin D: Foods to Include in Your Diet
Your diet is a big part of getting enough vitamin D. Eat foods that are naturally high in this nutrient or have it added. Here are some important vitamin D food sources:

But, food alone might not be enough for everyone, like those with certain diets. Low vitamin D can cause problems like weak bones and muscles.
The Role of Sunlight in Vitamin D Production
Sunlight is another natural way to get vitamin D. Your skin makes vitamin D when it’s exposed to UVB rays from the sun. But, your skin color, where you live, and the season can affect how much vitamin D you make.
To get the most sunlight:
- Spent at least 15 to 30 minutes in the sun several times a week.
- Choose midday sun, as it’s strongest.

For some, like older adults or those in cloudy places, vitamin D supplements are a must. The daily amount needed varies by age and health, usually between 600 IU and 800 IU for adults. Those over 70 need 800 IU a day.
| Age Group | Recommended Daily Allowance (IU) |
|---|---|
| Under 70 years | 600 IU |
| 70 years and older | 800 IU |
When picking a supplement, vitamin D3 is better than D2. Vegans can find plant-based options. Don’t take more than 4,000 IU to avoid side effects. Consider your risk, lifestyle, and diet when deciding if you need supplements.
