The acceptable range is up to 100ng/l for vitamin d 3. The 50ng/l is in the acceptable range, the question is do you see disease rates lower than a particular number or greater than a particular number that is caused by that number. As far as I know they can't determine if a particular number causes a disease except above 100ng/l and below 20ng/l. The endocrinology society(or whatever their exact name is?) decided to raise to above 30ng/l a year or 2 ago. There are studies that support higher numbers than 30 for various diseases based on cancer survival rates being higher when the number is such, colon cancer I think was 32ng/l and breast cancer was 50ng/l, these are close to the numbers that I remember and may be the exact numbers.
There is not a chart that you can look at and say if I want to avoid this disease than I will pick that number and then read on and see another disease and say ooh, I don't want that disease either, so I pick that number instead. The only thing that you can probably get Doctors to agree on at about 100 percent is below 20ng/l is too low and above 100ng/l is too high. There needs to be more practical work and analysis on vitamin d 3 numbers. Or a combing thru of existing clinical trials to see if a more thorough explanation can be determined from the existing data.
The question to ask is. What is your supporting documents for that level of vitamin d 3 in this situation? If the answer is dammit Jim, I'm a doctor, you may want to take the advice or not.
