I doubt it. I am very fair skinned and get get vitamin D in a prescription form because I am severely deficient and unable to process it properly. This week I take one 10,000iu once a day and after that will take 2 per week to try to keep my levels up to normal.

I'm sorry for your difficulties and hope the treatment helps but you're one case. My question was in general terms across the population at large. Do fair skinned people tend to have fewer cases of colon cancer because the vast majority if them over produce vitamin D from sunlight?
