My wife's vit D level was 7 also. She was prescribed 50,000IU pills of D2 to take twice a week. They told her to come back in 12 weeks. She's also taking 5000IU of D3 several times a week that the doctor doesn't know about. Her platlettes also were slightly elevated.
I heard from a reliable source that vit D levels this low could point to something very sinister...it may mean there is inflammation or a serious underlying condition that is 'using up' all the vit D in the body. Wife has appt with oncologist today, hopefully they will order up some really good labs to get to the bottom of this.
Also, if your vit D is way low, good chance you have bone issues as your body can't absorb calcium w/o vit D. Make sure you take the vit D with a fat such as coconut oil or after a meal w/plenty of fat.
So the wife goes to the oncologist today who is also a hemotologist and he checks her platlettes. Finds the are still high, just maybe 10% above the range. Says it's worrisome and wants to recheck her in 90 days. Says if it's still high he wants to do a bone marrow biopsy. Also says her super-low vit D level is completely unrelated. He didn't order any labs. I think he's a quack and we need a new dr.
