In “B12 deficiency: a silent epidemic with serious consequences,” Chris Kresser says:
What do all of these diseases have in common?
- Alzheimer’s, dementia, cognitive decline and memory loss (collectively referred to as “aging”)
- Multiple sclerosis (MS) and other neurological disorders
- Mental illness (depression, anxiety, bipolar disorder, psychosis)
- Cardiovascular disease
- Learning or developmental disorders in kids
- Autism spectrum disorder
- Autoimmune disease and immune dysregulation
- Male and female infertility
Answer: they can all be caused by vitamin B12 deficiency.
But what does it do? For what do we — and our children — need it?
Vitamin B12 works together with folate in the synthesis of DNA and red blood cells. It’s also involved in the production of the myelin sheath around the nerves, and the conduction of nerve impulses. You can think of the brain and the nervous system as a big tangle of wires. Myelin is the insulation that protects those wires and helps them to conduct messages.
Severe B12 deficiency in conditions like pernicious anemia (an autoimmune condition where the body destroys intrinsic factor, a protein necessary for the absorption of B12) used to be fatal until scientists figured out death could be prevented by feeding patients raw liver (which contains high amounts of B12). But anemia is the final stage of B12 deficiency. Long before anemia sets in, B12 deficiency causes several other problems, including fatigue, lethargy, weakness, memory loss and neurological and psychiatric problems.
Chris also says:
B12 is the only vitamin that contains a trace element (cobalt), which is why it’s called cobalamin. Cobalamin is produced in the gut of animals. It’s the only vitamin we can’t obtain from plants or sunlight. Plants don’t need B12 so they don’t store it.
So make sure you — and your children!! — eat meat!! Or at least supplement!!
