Vitamin D Deficiency despite efforts to correct! Help?

I recently had my yearly physical, and the only thing that was off was my Vitamin D. It was coming in at 21 (should be at least at 30 for the low range). At this point, I had been taking 1,000IU of Vitamin D per day, along with getting lots of sun. After expressing my concern, my doctor recommended I increase my IU to 4,000 per day and retest in 8 weeks. I retested this week and I'm still very low at 26.5

I take the Vitamin D with fat (avocado/eggs) every morning with breakfast. I am outside for at least an hour each sunny day with quality time for sun exposure. 

(I do live in Minnesota)

My doctor doesn't seem very concerned, but I am! I know how important Vitamin D is to my immune system, bone health, and I know there are tons of links with Vitamin D deficiency and breast cancer.

Any ideas of where I should go from here?

100iU is pretty small, you'd need twice that daily to make a dent. It can take some time to raise serum vitamin D levels.


Some folks have broken Vitamin D receptors, a genetic test via 23andMe/ancestry.com then taken to promethease.com can reveal that.
