current vitamin B12 recommendations are too low. Proper vitamin B12 biomarker testing reveals this fact. The problem is most people fall prey to the lack of knowledge behind simple serum levels. Simple B12 serum levels are woefully inadequate. Insurance would rather one stay with inadequate testing to save money, rather than actually read the science to learn about new testing.

cross sectional study finds low vitamin D associated with a decrease in SHBG and an increase in free Testosterone; a decrease in estradiol and an increase in DHEA was seen in women. No association with total Testosterone was found. There are studies that show a direct decrease in testicular Testosterone production in men with low vitamin D and decrease in AR function.
