Symptoms of vitamin B12 deficiency include: Anemia Intestinal disorders and weight loss Fatigue, weakness, lightheadedness Memory loss or confusion Depression or dementia Rapid heartbeat and respiration Mouth or tongue soreness or bleeding Excessive bruising Injections are the most effective means of administration of vitamin B12 since they do not depend on the body's ability to absorb the substance through the gastrointestinal tract
The FDA does inspect compounding pharmacies but does not test every individual batch
High B12 without supplementation is a different clinical picture entirely
Every prescription is documented and compounded according to strict quality procedures
It should only be handled by licensed, qualified professionals
This favorable preclinical safety profile has led investigators to advocate for the initiation of formal human trials [52, 83]
