Vitamin D - What are Optimal (healthy) Levels?

Whenever you are addressing a health issue: "Normal" is not necessarily "Healthy". Always find out what is "Optimal" and go for that and settle for nothing less
When interpreting Lab test results for Vitamin D:
Optimal 25-hydroxy vitamin D values are:
  • 45-50 ng/ml or 115-128 nmol/l
Normal 25-hydroxy vitamin D lab values are:
  • 20-56 ng/ml 50-140 nmol/l
Your vitamin D levels should NEVER be below 32 ng/ml, or the equivalent in nmol/l. Any levels below 20 ng/ml are considered serious defiency states and will increase your risk of breast and prostate cancer, osteoporosis and autoimmune diseases like MS and rheumatoid arthritis - to name a few.
