Vitamin B12 is generally considered safe and non-toxic, even at high doses. The body is able to excrete excess vitamin B12 through urine, so the risk of overdose is low. However, it is still important to follow recommended dosages and consult with a healthcare professional before taking high doses of any vitamin or supplement, as individual needs and tolerances can vary. In some cases, excessive intake of vitamin B12 may lead to certain side effects or interactions with medications, so it's important to use caution and seek guidance from a healthcare provider. **

It is possible that their traditional diets include fermented foods, certain plants, or other sources that provide them with sufficient vitamin B12. Additionally, their gut microbiome may be more efficient at producing or absorbing vitamin B12 compared to individuals in modern societies. It is important to note that individual differences in genetics, lifestyle, and dietary habits can also play a role in vitamin B12 absorption and utilization. **

Additionally, some research suggests that methylcobalamin may have unique neurological and cognitive benefits compared to other forms of B12. **
