Humanin vs Methylcobalamin

Humanin vs Methylcobalamin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Humanin
Mitochondrial & Longevity

Humanin is a 21-amino acid mitochondrial-derived peptide (MDP) encoded within the 16S ribosomal RNA gene (MT-RNR2) of the mitochondrial genome - the same mitochondrial gene region that encodes MOTS-c. Discovered in 2001 from a cDNA library screening against Alzheimer's-linked neu...

Methylcobalamin
Mitochondrial & Longevity

Methylcobalamin is the biologically active, methyl-group-carrying form of Vitamin B12 (cobalamin). Unlike cyanocobalamin (the synthetic form found in most oral supplements), methylcobalamin is the form that functions directly in the central nervous system and participates in the ...
