If you have a sulfur allergy, liver disease, or are pregnant or breastfeeding, you should consult with a provider first before taking MIC + B12
As the body ramps up red blood cell production in response to B12, potassium can be used up, so your provider may recommend monitoring it with a blood test
In the UK, the standard NHS regimen for B12 deficiency without neurological involvement is hydroxocobalamin 1mg IM three times a week for two weeks
In my experience, injections in the skeletal muscles (intramuscular injections) result in a more dramatic improvement in symptoms including energy and weight loss

For individuals with digestive sensitivities, those taking acid-reflux medications, or anyone on a plant-based (vegan/vegetarian) diet, absorbing enough B12 through food or pills is virtually impossible
