Infra red is awesome. Look up sunlight on medcram for more info.
Uvb is awesome. But you get diminishing returns after sunbathing for 20min.
Uva is shit. So the best time is when the sun is at its peak and uvb concentration is the highest.

Another thing to note, you can't actually produce any vitamin D if you aren't eating the right foods for the precursor.

i've known this, you also burn the fastest between 12 and 3, but its the only time you can get D in europe especially. you can look up the UV levels online on weather forecasts, typically they warn people to avoid the sun between 12-3 and show those UV levels with red.

it doesn't matter if you're in the sun, a general rule is that if your shadow is taller/longer than yourself you wont gain any vitamin d, however during the early morning and evening it might be more red light, which has its own benefits.


the best method is basically to be in the sun from morning and then get 20-30 minutes during the peak, then kind of avoid it, don't tan and you will only keep your skin young, then maybe take moderate supplement doses in fall/winter to maintain levels.
