Vitamin D supplementation in Winter vs Sunlight in Summer


Senior Member
I'm curious if any of you have found supplementing vitamin d in the winter gives you the same effect as natural sunight in the summer?

I understand we are all different in response to supplementation,climate and genetics

Thank you
There are better chances to have a good effect on vitamin D directly from the sun. although the supplement can also help.

Vitamin D helps me with brain fog and mood, also it regulates m y circadian rhythm if I take it very early in the day.
