Elevated serum B12 levels (hypercobalaminaemia) detected on blood tests may indicate underlying conditions such as liver disease, kidney dysfunction, or myeloproliferative disorders rather than representing a direct cause of symptoms
B12 injections are generally well-tolerated and safe
So, to ensure your body absorbs the B12 effectively, staying hydrated is key
Your batch is inspected, labeled, and sealed
Low dead space syringes are designed to minimize this loss and are worth the marginal extra cost
When given by intramuscular injection, the dose bypasses the digestive tract and is absorbed reliably, which matters because dietary B12 absorption depends on stomach acid and a protein called intrinsic factor, both of which decline with age, medication and certain gut conditions
