Most people get enough vitamin B12 in their diet, but some need supplementation
It has also been stated that Cbl, along with other B complex vitamins, positively affects the immune system, and deficiencies in these vitamins can decrease immune responses and T-cell proliferation [54,55,56]
Periods do not always arrive exactly on time, and in many cases, this can be completely normal
While B12 can be taken orally, injections or IVs are really the most effective, absorbable ways to get B12 into your system
However, other symptoms of low B12 can make you feel crappy at the very least, and at their worst leave you hospitalized or bedridden (intense, right?) These include: Dizziness Fatigue Memory loss and dementia Confusion, particularly in the elderly Nerve pain Irritability Mood disorders Difficulty concentrating Cognitive impairment Shortness of breath Nerve demyelination Growth failure and brain injuries in babies Tremors Brain Atrophy Looking back on my days as a hospice nurse, I wonder how many of my patients had B12 deficiencies and could have gotten significant relief from a simple supplement
