According to sources including StatPearls, a serum B12 level between 200 and 300 pg/mL is considered borderline, not definitively low. A result of 250 pg/mL falls squarely in this ambiguous range, meaning it requires additional medical evaluation rather than an automatic diagnosis of deficiency.

Approximately 20% of adults over 60 have a vitamin B12 insufficiency, yet mild cases are frequently overlooked. A mild or borderline B12 deficiency is a state of marginal insufficiency that can cause subtle symptoms and, if left unaddressed, could potentially worsen over time.

While some labs might classify a vitamin B12 level of 250 pg/mL as technically within the 'normal' range, many experts consider this value to be borderline or even potentially insufficient. This gray area often warrants further investigation, especially if you are experiencing subtle symptoms of deficiency. Understanding what this level means for your health is the first step toward proactive wellness.

According to the National Institutes of Health, B12 levels between 200 and 300 pg/mL are considered borderline, potentially leading to a variety of subtle symptoms. While not a full deficiency, knowing how do you treat B12 borderline is crucial for preventing more serious health issues and improving overall well-being.
