vitamin D

[Flash]

@lylemcd

Studies have also examined what are thought to be optimal levels of serum D (e.g. 30-50 ng/dl depending on who you read). Those levels are generally NOT achievable with intakes of the DRI and many are suggesting an increase in the DRI to much higher levels (e.g. 800 IU/day to 2000 IU/day).

It’s not all deficiency stuff being misinterpreted as you suggest above.

Lyle, do you have any opinions about the values that are considered optimal? 30-50ng/dl has traditionally been used as the recommended optimal range, but I have also seen recommendations that 50-99ng/dl is optimal.
