can vitamin b12 injections cause insomnia Vitamins and insomnia: Correlation and more how often should i get

How you react largely depends on your specific situation

Two common evidence-based patterns: How fast will I feel better

So, while we dont get much B12 in the water anymore, we dont get much cholera, either, which is a good thing

Other reactions warranting urgent GP contact include: Unexplained muscle weakness or cramping Persistent vomiting or severe abdominal pain Signs of hypokalaemia (low potassium) during initial treatmentmuscle weakness, irregular heartbeat, or severe fatigue In patients with severe, longstanding B12 deficiency, rapid correction can occasionally precipitate hypokalaemia as new red blood cells are produced, consuming available potassium

For example, B12 helps convert food into glucose rather than storing it as fat, which boosts energy levels
