b12 injection leg cramps What happens if you inject wrong? How to Give B12 Injections

Some studies suggest that B12 shots provide a more immediate and potent effect than pills, mainly because the vitamin is injected directly into the bloodstream

Clinical signs of B12 deficiency include nausea, vomiting, loss of appetite, poor absorption of food (malabsorption syndrome), constipation, gas, weight loss, fatigue, lethargy, abdominal pain, and diarrhea

Methylcobalamin also supports neurological health and may remain in your system longer than cyanocobalamin, offering a more sustained benefit

The sensation you felt after drinking the wine may, or may not, have had anything to do with the B12 but personally I have a tiny (snifter) glass of fortified wine every day without any adverse effect and I'm still " clivealive " and nearly 77 years old Don't forget to get your Folate level checked, Thank you clivealive
