Mine was a 12 when it was first tested. My neuro have me taking 4000 IU of D3. Last time it was tested it was in the low normal range. That is when he increased the dosage from 2000 to 4000.

KittyLady - Be careful taking that much vitamin D without the testing. Too much vitamin D can cause your blood calcium to rise and cause other problems. I never supplemented with vitamin D before for this reason.

My calcium was fine so I don't need to supplement with any calcium. Since I am low on funds, I took the D2 prescription. According to the article, both D2 and D3 supplementation increases over the first few days at about the same rate. I hope to get to the bank so that I can get the D3 supplements. (Insurance covered the D2). I also plan on spending more time out in the sun. Don't worry Aussiemom, I plan on only doing 10 minutes in the morning sun a few days a week. I don't want skin cancer either and it does run in my family.
