2K IU per day likely won't help much. Use what you have for a few weeks until next labs. If you're still low, then I'd opt for the 50K IU dry D3 from Vitalady.com . I had an 8 for my post op D labs. Script D was a waste of time--after 6 months it rose to 14?? One month on a liquid vitamin with only 600 IU dry D3 and my D labs were a 33. I then went to 4 of of the 50K IU per week of the D3. Two years later, labs were at a 65. So at year 5 post op, I decided to make another uptake in my dry D3, taking one 50K IU daily, or 7 per weeek. After 16 months, my D labs finally came back at 104. Target areas (based on several studies) says 80-90 for D labs for the general public and wt loss pateints is very desirable. Since I finally made it to 90+, I've adjusted my D3 to 6 of the 50K IU per week. Each patient is different in the amount of D3 to put them at 80-90, so adjust your D3 intake based on lab reports.
I had severe bruising on my forearms for almost 4 years post op. I finally asked my surgeon's nurse, and she said to take some additional vitamin K. K is one of the vitmanins we need as post ops, and some major vitamins have no vitamin K in them. The K supplements are very inexpensive, small and easy to swallow. I get mine from Puritan Pride vitamins when they have their common buy 2 get 3 free sales.
On the topic of cramps, this issue has been discussed at my support groups. Low potassium levels can cause this issue, so you may have to take a potassium supplement. DAVE
