Is it prescriotion D? All of the prescription D I have seen is in oil, and D2, not D3.

D2 must be transformed in our bodies to D3 before it can be used. Only a small percentage becomes D3. If it is in oil, we absorb even less. You are likely getting very little benefit from prescription D2. You can get dry D3 inexpensively on Amazon and other places, and it will boost your numbers much better.

Normally I'm a naysayer too, but these results were in fact pretty right on. And it makes sense that I'm not able to absorb the B vitamins so there just sitting in my blood. It makes me wonder if the people who have elevated B12 on this board all have the very common gene polymorphism MTHFR mutation? Time will tell for sure once I start supplementing with what they suggest, if it makes my symptoms go away. But I'm not throwing the baby out with the bath water on Spectra Cell yet.

Thx for the help guys. I'm still pondering this high b12 thing. Read an interesting article on it. http://www.yourhealthbase.com/B12overload.htm

It's interesting because I went to a nutritionist who did blood work through a company called Spectra Cell that measures the amount of each vitamin/mineral is actually being absorbed by my cells. This report came back saying that I'm actually LOW in B12 & other B's incidentally which means that even though I've got Vit B12 floating around in my blood, it's not actually being absorbed. All this lead me to discover that I have the Mthfr gene mutation that doesn't allow my body to absorb B or folate in top of having our surgery- oy vay! Thought it may be useful to all of us to read the article at least.

I also have always had very high B12 - haven't taken it for years. I think my multi has a small amount.

Do you take any fiber? I add a scoop of really good organic fiber to my morning beverage to help keep things regular. I take massive amounts of calcium and have never had issues with constipation. Hope you find some relief.
