Fatigue, lightheadedness, and overall weakness are the most common symptoms of low B12
Always confirm the ratio against your own vial's exact mg amount before drawing a dose
Up to 1:1 Cu(II):octarepeat molar ratio, this region binds a single Cu(II) ion by four imidazole sidechains of His residues, from 1:1 to 2:1 Cu(II):octarepeat molar ratio, each Cu(II) ion is coordinated by two His sidechains and two amide nitrogens 27 , and possibly an additional carbonyl oxygen 24,25 , where starting from above 2:1 Cu(II):octarepeat molar ratio each His sidechain starts to coordinate a single Cu(II) ion with two amide nitrogen and one carbonyl, from the neighboring Gly, binds a single Cu(II) ion 24,25
Reports are inconsistent: some community sources describe no perceptible effect at all, and there is no placebo-controlled human data to separate signal from expectation
