1500 mcg b12 injection Compounded Methylcobalamin (Vitamin B12) Injection, 5mg/mL Cyanocobalamin (Vitamin B12) Injection is sold as an FDA approved generic drug Methylcobalamin B12 Injection in Beverly
Description
A blood test is an indication for how much the brain might have access to B12, but if for instance the blood-brain barrier does not absorb enough B12, the brain will have too little B12, while the blood test is normal

This is because it is water-soluble, so most ingested B12 is actually flushed out in the urine

If you are experiencing symptoms such as fatigue, weakness, numbness, or memory problems, these could be signs of a B12 deficiency

Not having enough functioning red blood cells to carry oxygen through the body will leave you feeling tired and weak as a result

However, despite promising efficacy and safety data, it did not advance to Phase 3 trials or obtain regulatory approval for therapeutic use
