there's also the alternative to create vitamin d3 with exposure to sunlight
from my understandind after reading articles and studies is that in order ur body to absort d3 from the sun you must not wash the skin for 48 hours after the sun exporsion

de is needed for bone healh,among others,it's critical for calcium metabolism

some links :






(this post is just an intro to vitamin d,more will come)
I have never heard that about not washing the skin after exposure to the sun. Guess that I am not really getting much out of it then since I refuse to go that long without a shower. I am a daily shower guy.
