Some people get a vitamin B-12 deficiency. B-12 is an essential vitamin (that is, our bodies cannot produce it) that supports nerve cells, red blood cell formation and DNA synthesis. For me, it manifested as a “brain fog” which felt like everything was run through a black and white television grain filter. I confirmed it with a doctor, and doctors offer B-12 injections. I opted for oral B-12 drops (purchased online). The “brain fog” lifted. I think the deficiency is from the low replenishment rate. We keep using our own stores but don’t get enough from the food that we eat. As we get older this cycle develops into a deficiency. I like using B-12 (in the Methylcobalamin form) that comes in a dropper bottle and I place a few drops with the dropper under the tongue. That basically tries to get some through the capillaries in your mouth and the rest from being ingested. Vitamin B-12 is a very large molecule and is easily destroyed, which is the reason that half a dropper is 50,000% the recommended daily value. You take a lot and statistically some will survive the digestive process. Basically, B-12 supplements are something that helped my brain fog, but please remember to talk to your doctor about your situation.
