Vitamin D - advice still unclear

[JimJimJimJim]

• Some doctors believe men with prostate cancer should take vitamin D supplementation to ensure their vitamin D levels are within the normal range. (Dr Snuffy Myers, for instance).
  
• As with all supplements, some doctors believe in much higher levels.
  
• Dr Mark Moyad is very wary of vitamin D supplementation.
  

Dr Moyad has said:

• You should remember that despite its name, Vitamin D is really a hormone. Hormones usually do not work if there is too little or too much.
  
• Many studies of large quantities of a number of supplements have shown harm to date. Taking large quantities of vitamin D may also do harm.
  
• Increasing you vitamin D by exercise, diet, and occasional sunshine does seem sensible.
  

Note that USA lab measurements of Vitamin D are in ng/ml, while in Australia nmol/ml (same as pmol/L) is used. My N&S report says the normal range is 65 to 175 pmol/L. Your doctor may use as an approximation nmol/L divided by 2.496 -> ng/ml.
