A few hours in the sun can deliver 10,000iu of Vitamin D3 and up to 30,000iu depending on how long and how few clothes. Even with taking in the sunshine as much as possible, I take around 10,000iu of Vitamin D3 in my supplements every day and more in the winter.

Whether you are in the South and covering up from the sun or in the North with winter approaching, I believe Vitamin D3 supplementation is essential.

Just look at a fraction of what the studies say:
