This activity supports cytosolic redox balance, particularly under high glycolytic flux, and contributes to energy metabolism and reactive oxygen species (ROS) generation in metabolically active tissues 55
However, they are also more invasive and require administration by a healthcare professional
That triple-agonist mechanism is what separates it from semaglutide (single agonist) and tirzepatide (dual agonist)
its administered via injections or capsules in clinical settings.[4] It enhances fat burning, energy, insulin sensitivity, muscle preservation, and repair, while indirectly boosting NAD+ by slowing depletion.[5][23][24] Its membrane-permeable nature allows efficient cellular entry, making it suitable for therapeutic use
Vitamin B12 injections could be useful for many individuals with a whole range of goals and motivations, but may be of particular benefit to those who are vitamin B12 deficient
