As your body absorbs B12 oral supplements and B12 injections in different ways, a dose of 1,000mcg of B12 taken orally is not equivalent to a B12 injection of 1,000mcg
However, always consult with your OB-GYN or midwife before starting any new supplement, particularly at higher-than-recommended doses
Seek medical attention immediately after you experience an allergic reaction
Reconstitution Math: 5mg Vial Add 2.5mL of BAC water to a 5mg (5,000mcg) vial: 5,000mcg 2.5mL = 2,000mcg per mL On a standard U-100 insulin syringe (100 units = 1mL): 300mcg dose = 0.15mL = 15 units 250mcg dose = 0.125mL = 12.5 units 500mcg dose = 0.25mL = 25 units 1,000mcg dose = 0.5mL = 50 units Reconstitution Math: 2mg Vial Add 2mL of BAC water to a 2mg (2,000mcg) vial: 2,000mcg 2mL = 1,000mcg per mL On a U-100 insulin syringe: 300mcg dose = 0.3mL = 30 units 250mcg dose = 0.25mL = 25 units 200mcg dose = 0.2mL = 20 units Step-by-Step Reconstitution Process Gather and prep Wash hands thoroughly

If you are feeling fatigued this spring, B12 deficiency is one possible explanation worth investigating but so are thyroid dysfunction, iron deficiency, sleep disorders, and numerous other conditions
