Wow, I'm taking 50,000 i.u. per week, b/c after my blood work came back, my Vitamin D level was so alarmingly low at a '5.' Normal is 45! No wonder I was depressed and tired.. It never occurred to me, until I changed doctors and the new doctor's first mode of business was to get a level on me...
Your doctor will be able to recommend the dosage based on your lab/bloodwork results. My doctor told me that over 2500 i.u. a day could possibly cause gallstones for me. Everyone is different though so I'd suggest having the bloodtest and following your doctor's guidelines. Best wishes!
Hello Erika,
Welcome to the Pain Management Forum.
You've asked a good question that does not have a simple answer. There are many factors that must be taken into account when determining the amount of Vitamin D each of us require on a daily basis. Even the the area of the country that one lives in should be considered. If you are exposed to a lot of sunshine this helps with the levels of Vit D.Floridians have less problems with Vit D deficiencies. If you are in a colder climate like the upper mid-west or in a rainy area like the state of Washington, it's near impossible to obtain enough sunlight to reach recommended levels.
Obviously your general health needs to be taken into the equation. If you have any problems with malabsorption as I do nothing but supplements will help you obtain adequate levels of Vit D.
Add to this the fact that there is a lot of debate, even in the medical community regarding what is the adequate daily intake of Vitamin D. Obviously it is always best to consult your PCP or even your pharmacist.
That said, the general consensus of 1,000 - 1,500 IU is usually a safe daily dose of Vit D. Please do not use that as a guideline, consult your PCP. As said earlier much goes into determining the amount of IU's that is right for you. Vit D is not water soluble vitamin and it can build up to toxic levels. So know or learn your bodies needs.
Hope this was helpful. There is so much more to learn about Vit D levels and requirements. I hope you will do some more research on the subject. Thanks for asking a good question.
Best of Luck,
