I'm aware of this. I just got mine tested and they were at 70nmol/l. I want to get it up to at least over 90 even over 100. Poliquin says that the higher you are in the normal range, his normal range of 80-100nmol/l, the better off you are in terms of health, hormones and building muscle. Well, the longer I have been taking D3, the better I have been feeling so I am going to keep it up til I hit 100nmol/l.
It took me 3 months of supplementing with 10,000 IU of vitamin D3 a day to just get to 70nmol/l. I will continue taking 10,000IU for another month and see where I am at again. If it is not moving I will up the dose to 15,000IU a day and go from there.
The reason I am curious is just to see what CT had been doing with his D3 supplementation.
