You eat healthy and take vitamins, but are you absorbing enough nutrients that your body can use?
Although my vitamin B12 seemed to look ok in a blood test, there were other indicators in my blood work that I was suffering from a deficiency. A heavy metal and essential elements test revealed the true picture: I had no detectable B12 in my body tissues. Well, a deficiency will cause fatigue, nerve problems, and immune system deficiencies as well.
I was taking plenty of supplements, but they weren't being absorbed properly.
I am now taking b12 shots, and I am really started to feel better....
