Actionable Insight: The next time you see a "B12 boost" offered, ask this simple question: "Is a registered prescriber on-site, and will they review my medical history and blood test results before treatment?" If the answer is no, or they seem hesitant, its a clear sign to walk away
Water-soluble vitamins like B12 are carried to tissues through water, but excess amounts aren't stored long-term
MTHFR A1298C variation has also been associated with decreased MTHFR enzyme activity, which can impact the bodys ability to metabolize vitamin B12
Unlike other vitamins, the absorption of vitamin B12 depends on a protein produced in your stomach, called the intrinsic factor
Supplements that contain only vitamin B12 tend to contain doses ranging from 500 to 1,000 mcg
