Higher Bioavailability : Injections provide higher bioavailability of B12 because the vitamin is delivered directly to the bloodstream, ensuring maximum absorption
Normalization of vitamin B12 (B12) levels achieved following 1000 mcg oral Eligen B12 therapy: a clinical study comparing the efficacy and safety of oral B12 therapy versus intramuscular (IM) therapy
PubMed 18068698 TB-4 / TB-500 product mislabeling documented bidirectional mislabeling between full-length TB-4 (43 aa) and the TB-500 fragment (residues 1723) in marketed peptide products: Esposito M et al
Additionally, in muscle tissue, mitochondrial translation and respiratory genes were also induced, and moreover, patients demonstrated a mild clinical improvement
In all our previous murine studies we have used short cycles (1014 days) of very low subcutaneal doses (20 g/kg/day) after carefully assessing its circulating concentrations and using the minimum amount that was sufficient to adequately restore physiological values of the molecule
Chemically, vitamin B12 can exist in a number of different forms, but all of them contain the mineral Cobalt
