Vitamin D - green stool?
On days when I know I didn't spend much time in the sun, I've been supplementing with 6000iu of Vitamin D (D3, Kirkland).
Whenever I do this, the next day, my bowel movements have a distinct greenish color to them. I feel fine, and they're otherwise the same as normal. I find some references to this with infants and Vit. D, but haven't seen it mentioned here or on other athletic/supplement sites.
Is it just me? Can anyone point me toward a link maybe explaining what's happening?
