Calculate your daily Vitamin D intake from sun exposure with this free online tool
Vitamin D is an essential nutrient that can be obtained through sun exposure, diet, and supplements. This calculator helps you estimate your daily Vitamin D intake from sun exposure based on factors like skin type, location, and time spent outdoors.
The amount of Vitamin D produced in the skin depends on several factors, including the time of day, season, latitude, and skin pigmentation. For example, people with darker skin types require more sun exposure to produce the same amount of Vitamin D as those with lighter skin types [Wikipedia].
To use this calculator, simply input your skin type, latitude, time of day, and time spent outdoors, and it will estimate your daily Vitamin D intake from sun exposure.
| Skin Type | Latitude | Time of Day | Time Outdoors | Vitamin D Intake |
|---|---|---|---|---|
| II | 40°N | 12:00 PM | 30 minutes | 200 IU |
| IV | 20°N | 10:00 AM | 1 hour | 400 IU |
