can you have b12 injections while breastfeeding Injection Breastfeeding: What Every Nursing Mother Should Kn – MomMed How to Give a B12

Do not try to "catch up" by injecting more

We will talk about this a little bit later, but it turns out that Vitamin B12 must go through several steps before it is properly absorbed through your GI tract and several hormone imbalances (including thyroid) can alter this absorption

Here is how they relate: 1mg = 1,000mcg (milligrams to micrograms) 1mL = 100 units (on a U-100 insulin syringe) Units to draw = (Dose in mg / Concentration in mg per mL) x 100 Or equivalently: Units to draw = Dose in mcg / (Concentration in mcg per mL / 100) Some researchers find it easier to work entirely in micrograms because it eliminates decimals

At 33.33 mg/mL, those doses equal 3, 4.5, and 6 U-100 units [18]

In the U.S., injectable B12 (cyanocobalamin and hydroxocobalamin) is only available with a prescription, as regulated by the FDA
