Typical Dosage Range Most men with low vitamin B12 levels receive around 1,000 mcg per injection, depending on their blood levels and health goals.( 9 ) However higher doses, as much as 2,000 mcg can also be safe in some cases
A deficiency in B12 can disrupt this process, leading to anemia, impaired red blood cell production and even nerve damage[7]
Many drugs look promising in cells, mice, or tissue samples but fail in later stages because: The treatment doesnt work well enough in humans It causes side effects at real doses The effect fades over time The human joint environment is much more complex than the lab So while we are hopeful, there is a long road ahead before this approach could become a real treatment
A 2024 systematic review published in a peer-reviewed orthopaedic journal acknowledged these findings while flagging a critical limitation: there are no completed Phase III clinical trials in humans
The body is not designed to produce vitamin B12 naturally
