bad for liver...
Hmmm... but the sun manufactured D on the skin isn’t absorbed right away or all at once, especially if one washes off the skin oil before it’s all absorbed.
Well, it’s theoretical, since I don’t take vitamins nor bask in the sun. Probably should worry about deficiency!
Thanks to both for info.
Qx was taking 10,000 units and the MD, after a routine blood screen, merely suggested cutting back some. He does, also, take liver enhancing stuff and no longer takes so much D3.
