Defender IV (Immunity Boost) Powerful immune support with B-complex, vitamin B12, high-dose vitamin C, zinc, and glutathione
Proton pump inhibitors, histamine H2 blockers, and heartburn medications meant to lower the acidity in the stomach can contribute to B12 deficiency
Because symptoms can have overlapping causes, these should not be used to diagnose B12 deficiency
Unlike pills or injections that need to go through your digestive system, B12 shots bypass this process and start working right away
