One of the main sources of vitamin D for the human body is the sun. UVB radiation can trigger vitamin D synthesis in the skin. However, in winter, our skin is almost completely covered with clothes, so we almost never get the vitamins necessary for health.
However, some foods contain vitamin D. These are salmon, tuna, beef liver, fish oil, fortified milk, cereals and mushrooms.
Since not everyone can get the amount of vitamin D they need from their diet, taking supplements may be another solution.
The recommended daily intake of vitamin D for people ages 1 to 70 is 600 international units (15 mcg). After age 70, this dose increases to 800 international units (20 mcg) per day because the aging body can no longer absorb it as efficiently as before.
It is generally safe to supplement with vitamin D concentrations ranging from 600 to 1000 international units. In this case, you are unlikely to experience any side effects.
