Vitamin B12 Deficiency is Excitotoxic, Part I
What do vitamin B12 deficiency-pernicious anemia, fibromyalgia, and multiple sclerosis have in common? More than you realize. For one, vitamin B12 deficiency occurs often with fibromyalgia, MS, and chronic fatigue syndrome. Another clue is homocysteine, an excitotoxin that rattles your nervous system, sometimes with debilitating results.
What are excitotoxins?
Dr. Russell Blaylock, author of Excitotoxins: The Taste That Kills defines excitotoxins as amino acids “that react with specialized receptors in the brain in such a way as to lead to destruction of certain types of brain cells.” Because they damage your nerve cells, excitotoxins are also referred to as neurotoxins.
Damaged nerve cells are one of the many side effects of vitamin B12 deficiency-pernicious anemia.
Homocysteine, for example, is an excitotoxin. Too much homocysteine causes your brain’s nerve cells to malfunction, breaking down the myelin sheathe and the blood-brain barrier (BBB), letting in free radicals, and potentially killing brain cells that can never be replicated.
Elevated homocysteine levels are also one of many side effects of vitamin B12 deficiency-pernicious anemia.
The following amino acids are classified as excitotoxins (neurotoxins):
- Homocysteine (L-cysteine)
- Glutamate (found in MSG and hydrolyzed vegetable protein)
- Aspartate (found in aspartame)
- Beta amyloid
Symptoms of excitotoxicity
The following symptoms may indicate nerve damage caused by excitotoxins:
- Chronic headaches (migraines)
- Painful tingling and numbness in your hands and feet (vitamin B12 deficiency)
- Muscular pain in specific sensitive spots (fibromyalgia)
- Unexplained constant tiredness, despite sleeping well and not overexerting oneself physically (chronic fatigue syndrome)
- Loss of muscular control (multiple sclerosis)
