Understanding your options and what to expect Delivery timing and how the process works General questions before you decide Symptoms of B12 Overdose Genuine symptoms directly attributable to vitamin B12 overdose are poorly documented in medical literature, reflecting the vitamin's excellent safety profile
By injecting B12, clients get the most bang for their buck as the vitamin does not have to bypass the digestive tract where much of its effectiveness is reduced
Reported side effects are typically mildsuch as injection-site irritation, headache, or fatiguebut regulatory reviews highlight potential immunogenicity and uncertainties around long-term safety and product quality in compounded or nonapproved forms
Patients are given an intravenous solution of the vitamin of their choice
Look for third-party testing showing greater than 98% purity, preferably 99% or higher
