How well can you produce enough vitamin D with sun protection?

the Federal Office for Radiation Protection (BfS) It states that to obtain adequate vitamin D, it will be sufficient to expose the face, hands and arms exposed and without sun protection to minimal ultraviolet radiation from sunlight for no more than twelve minutes two to three times a week. “Longer exposure to radiation does not increase vitamin D, but only increases the risk of health damage associated with ultraviolet radiation,” the website states. By the way. If left unprotected for twice that long, there is also a risk of sunburn.

Vitamin D can only be formed from UV-B rays.

The intensity of UV-B radiation is critical for the production of vitamin D in the body. In Germany, UVB rays in winter are often not enough to produce enough vitamin D. In contrast, high UVB radiation in spring, summer and fall enables enough vitamin D to be synthesized in a short time.
