The best and most natural way to get the vitamin D that you need is through sun exposure. This is because humans evolved to be out in the sun and safe, sensible sun exposure is associated with benefits outside of vitamin D production.
Now, in today’s world it is very hard for many to get outside during the right time of day for vitamin D production, or they live in areas where sunlight capable of vitamin D production doesn’t reach Earth’s surface.
That is why we recommend supplements as the next best bet. Overall, we would recommend that you get moderate sun exposure between 10:00AM and 2:00PM on the days that you can, and supplement on the days that you cannot.
