3 warning signs you are low in Vitamin B12


Vitamin B12 deficiency is common in vegetarians, older age and with chronic digestive issues. If any one of these is you, it pays to know the warning signs.

Here are some of the main symptoms that could indicate you are low in this crucial vitamin:

  1. Fatigue and shortness of breath after exercise could be early signs of anemia, which is a key sign of vitamin B12 deficiency.
  1. Vitamin B12 deficiency affects your mood and mental function, that's why depression and other mood changes are one of the major symptoms.
  1. Brain fog, poor attention and memory problems are all warning signs as well. If you are not feeling yourself and notice these it could be down to low B12.

The good news is low B12 can be treated with by a vitamin supplement. If your symptoms are serious you should see a doctor. Otherwise, try 500-1000 mcg daily for a month. And take a daily multivitamin with at least 30 mcg of B12 to keep you topped up in the future. If you are older than 50 years should take at least 400 mcg per day of supplemental vitamin B12 to ensure you avoid deficiency.
