High Vitamin B12

An increased level of vitamin B12 in blood ranges above 900 pg/ml. This indicates the presence of renal dysfunctions, liver disorders, diabetes, and leukemia. High doses of vitamin B12 can cause dermatologic conditions like acne and rosacea, which produces pus and redness. The excess vitamin is stored in the liver, and when not consumed it takes about three to five years to exhaust the stored vitamins.
