b12 injection breastfeeding 8 Best Postnatal Vitamins B12 Injection Dosage and Frequency:

Can do well with supplements Most doctors here in the UK will do anything rather than prescribe injections, even if it's clear you can't absorb B12 from oral supplements

Neurological symptoms can manifest in various ways and may include: Numbness or tingling in the hands and feet (peripheral neuropathy) Difficulty with balance and coordination Memory problems or confusion Mood changes, including depression or irritability Difficulty concentrating or 'brain fog' These neurological manifestations occur because B12 deficiency affects the nervous system's ability to function properly

Other symptoms of B12 deficiency, such as numbness and tingling in the hands and feet, are also common in people with diabetes and spinal stenosis

Because B12 is found almost exclusively in animal foods, the NIH notes that vegans and vegetarians face a higher risk of deficiency without supplementation

The injection is typically given intramuscularly, meaning it is injected directly into the muscle, allowing for quick absorption into the bloodstream

Individuals with severe B12 deficiency benefit most from IV infusions because intravenous delivery raises serum levels faster than other supplementation routes
