You would : Have to have occasional blood work to determine what your levels are. Vit d in high doses can be toxic.

Generally safe: 2000 units of d3 is a usually daily dose, but 4000 a day shouldn't be a problem for most people. Have your lab checked at intervals. Don't know if it'll be effective against psoriasis. Talk w/your dermatologist.
