Vegetarians and vegans lack dietary B12 sources unless they consume fortified foods
Athletes often seek ways to improve their stamina and recovery times, and adequate levels of B12 can contribute to better oxygen transport in the blood, which is crucial for endurance
Common symptoms like anemia, memory loss, confusion, and tingling are signs of it
Pharmacokinetic studies in rats demonstrated an oral bioavailability of 38.4%, with a mean Cmax of 2,252 ng/mL and terminal elimination half-lives of 3.80 1.10 hours (IV) and 6.90 1.20 hours (oral) (Awosemo et al., 2021)
In general, we advise a weekly shot for four weeks, then a maintenance dose per month
