do not eat animal products, ask a healthcare professional how to safely meet your B12 needs.
Treatment: Tablets or Injections
Treatment depends on the cause. Some people can improve with oral B12 supplements. Others need injections, especially when the body cannot absorb B12 properly.
The NHS says people with neurological symptoms such as numbness or tingling caused by B12 deficiency may need referral and injections every 2 months in some cases.
Never stop treatment early without medical advice. Symptoms may improve slowly, and follow-up may be needed.
