Nutrition: Vitamins on trial

It is also dependent on your profession and location. If you are a collegiate or professional athlete living in the Northern US where sunlight exposure is generally bad for 6 months out of the year, then while your Vit D levels may just be below-average (but nothing major for a normal human), this could be a real issue regarding athletic performance.

Supplementation and testing must always be taken in context. The average sedentary human does not have the same caloric needs as the aspiring professional athlete, nor do they have similar supplementation needs either.

I fully agree. Athletes, pregnancy, high-stress jobs, depression, etc. Each have different concerns and specific nutrition focusing on them can be quite efficient at mitigating symptoms/improving results. Also location as you mentioned and genetics as well can influence the requirements of certain nutrients.

This

I don't remember the exact numbers, but if the sun is out there, around 10min (or maybe up to 30min) under the sun with light clothing will give you the needed Vitamin D dosage.

Now, in high latitude winter, the time needed is in the order of hours. With heavier clothing this becomes much harder.
