Tag: Elevated b12 levels

While excess B12 is often excreted through urine, a persistently high blood concentration can sometimes signal an underlying health issue rather than just a supplement overdose. While many people with elevated levels experience no symptoms, others may report unpleasant side effects.

According to the Cleveland Clinic, it is common for people to have high B12 levels with no symptoms, as the body typically excretes excess amounts. However, in some cases, certain symptoms can manifest, often indicating an underlying medical condition rather than the vitamin itself. Understanding what symptoms are there if B12 is high can help you determine when to seek medical advice.
