Do you realize that when you take a vitamin D3 supplement, it is not the same as the one you make in your body? We make vitamin D from getting UVB rays on our skin that convert cholesterol to pre-vitamin D, which is then thermally isomerized into vitamin D. The correct name of vitamin D is cholecalciferol. Notice the name has a huge clue for the cholesterol that is used. Just another reason to get into the sun. Also, people taking statins may have a harder time making vitamin D because of lower cholesterol levels. This is a huge reason to maybe rethink about what level you want your cholesterol to be.
Have you heard all the doctors saying to stay out of the sun especially midday? Well UVB rays are only strong enough to help you make significant amounts of vitamin D from around 10AM-2PM depending on where you live. So, you need midday sun to make vitamin D. This is incredibly important to your health! Everyone needs to get outside midday with bare skin, so take your lunch outside and show as much skin as possible. Yes, I’m saying no sunblock! If you have VDR gene variations then you need to stay longer in the sun and potentially show more skin. Always be careful at first so you don’t burn. How much sun exposure you need also depends on your skin color. Lighter skin makes it faster and darker makes it slower. Please realize that you cannot supplement this process! Summertime is the best and most efficient time to make vitamin D depending on where you live so get outside as much as possible.
As always, this is educational and not medical advice.
