I think the number is actually 8000 IU (missed a zero). The old recommendations used to be below 5000. I've read that 15 minutes of sun exposure (maybe 20-30 at high latitudes) generates 10,000 IU and dumps it directly into the blood stream. Funny that...

It's still important to get D through diet though, as it facilitates calcium and magnesium absorption in the gut. D in the blood might be good for other things (mood, cellular health, metabolism), but it does nothing for mineral absorption.

My rules:
1) eat real food - more vegetables, moderate meat, moderate fruits, less grains, less sugar, less vegetable oils.
2) exercise - moderate intensity cardio, sprinting, heavy lifting, dedicated stretching and mobility.
3) live - relax, de-stress, meditate.
