Tag: B12 half life

Unlike most other water-soluble vitamins, vitamin B12 is stored in substantial amounts, primarily within the liver. This robust storage capacity means a deficiency can take years to manifest, leading many to ask: How long does vitamin B12 stay in the body?.

The liver is remarkably efficient at storing vitamin B12, often holding several years' worth of reserves. Despite this, how long does it take B12 to leave your system in other ways? The answer depends on whether you're talking about the immediate clearance of excess B12 or the long-term depletion of your body's stored supply.

Unlike other water-soluble vitamins that are quickly flushed from the system, vitamin B12 has a unique storage mechanism that allows the body to retain it for an extended period. This exceptional storage capacity is a key factor in understanding how long will vitamin B12 stay in your body and why deficiency often develops gradually over several years.

While excess vitamin B12 is a water-soluble vitamin that is rapidly excreted through urine, the body also maintains long-term stores in the liver that can last for years. This means the speed at which it exits your system depends heavily on whether you are clearing a recent surplus or depleting your body's reserves.
