You won't piss out Vitamin D overdoses. It's fat soluble so if you're fat you store in in your fat cells. If you're skinny you store it in your blood. A most unfortunate circumstance as blood isn't really designed for this and becomes over-calcified. Vitamin D's job is not to prevent inflamation or viruses, it is to make calcium absorbable in your blood. The excess calcium then deposits itself on the walls of your veins and arteries and overtaxes the organs which have to remove it.

The main consequence of vitamin D toxicity is a buildup of calcium in your blood (hypercalcemia), which can cause nausea and vomiting, weakness, and frequent urination. Symptoms might progress to bone pain and kidney problems, such as the formation of calcium stones.

So knock yourselves out with your supplement pills. I'll have a serving of salmon, some eggs, a glass of milk or some cheese. Go for a walk in the sun, your body will make its own!

Good coffee, good weed, and time on my hands...
