We get 20,000 iu of Vitamin D in like 15 to 30 minutes of sun (if you're pale skinned). Pretty sure taking 5,000 iu every day isn't going to be harmful.
Also, fun side note: Vitamin D is produced as an oil on the skin and actually seeps through your skin overtime to enter the bloodstream. So don't take a shower after getting some sun, because you could be washing off your Vitamin D.
