Barbara Z Kravets CCN LDN, CCN LDN PRIVATE PRACTICE Send rapid response to journal: Re: Questions regarding levels of 25 OH D and 1, 25 OH D and PTH licnutrition{at}hotmail.com Barbara Z Kravets CCN LDN	Dear Sirs: In re: your article Gains in Bone Mineral Density with Resolution of Vitamin D Intoxication John S. Adams, MD, and Gene Lee 1 August 1997 | Volume 127 Issue 3 | Pages 203-206 in Annals of Internal Medicine. Thank you for your interesting article. However, I would appreciate if you could answer questions for me: 1) What was the level of Vitamin D consumed? Two sententences, as below, are confusing. "No patient knowingly consumed more than 1200 IU of vitamin D daily or took other medications known to alter skeletal metabolism." "Some of these products were advertised as containing as much as 3600 IU of vitamin D3 per daily dosage" 2) What were the measured levels of 25 OH D3 and 1,25 OH D3 and 25 OH D2? 3) What was the measured level of Parathyroid Hormone? 4) Was was the animal extract product?. 5) What was the level of Calcium measured? Thank you for your attention to my questions. Barbara Zeitlin Kravets CCN LDN licnutrition@hotmail.com Conflict of Interest: None declared
