Vitamin B12 Deficiency is Excitotoxic, Part II

Friday, March 2nd, 2012

 

 

What do vitamin B12 deficiency, 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.

Part I introduced you to excitotoxins…now in Part II, find out how to keep neurotoxins from disrupting your life.

What illnesses are linked with excitotoxicity?

Many neurodegenerative illnesses and other conditions are linked with elevated levels of excitotoxins such as homocysteine:

  • Fibromyalgia
  • Migraines
  • Multiple sclerosis
  • Pernicious anemia (Vitamin B12 deficiency)
  • Hypoglycemia
  • Seizures
  • Stroke
  • AIDS dementia
  • Huntington’s disease
  • Alzheimer’s disease
  • Parkinson’s disease
  • Infections
  • Lyme borreliosis

“Glutamate and aspartate are doubled in viral meningitis, acute multiple sclerosis (MS) and myelopathy compared with control subjects and patients with peripheral facial nerve palsy.”

What causes elevated homocysteine levels?

When your body produces homocysteine, it is immediately broken down by vitamin B12 (cobalamin) and vitamin B6 (pyridoxal phosphate).  Vitamin B12 and vitamin B6 keep your homocysteine levels down to a healthy minimum where already healthy homocysteine levels occur.

However, if you have vitamin B12 deficiency, including pernicious anemia, then you don’t have enough vitamin B12 to break down homocysteine. 

As a result, homocysteine levels spike, permeating your neurons, causing irreparable damage to your nerve cells and increasing your risk for stroke, heart attack, blood clots, and memory problems.

“…increased homocysteine levels in the central nervous system characterize patients fulfilling the criteria for both fibromyalgia and chronic fatigue syndrome.”

Here’s Your Brain on B12 Deficiency- Memory Loss and Aging

If you have pernicious anemia, then you may not be able to digest dietary forms of vitamin B12 (food, pills), due to a digestive system disorder.

In order to maintain healthy homocysteine levels (and thus gain the neurological health benefits of B12), you need to insert vitamin B12 directly into your bloodstream through vitamin B12 shots.

For maximum vitamin B12 benefits, experts recommend supplementing with extra over-the-counter (OTC) vitamin B12, as well.  Many patients experience improved neurological health in as little as a few days following vitamin B12 supplementation.

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.

VITAMIN B12 DEFICIENCY IS EXCITOTOXIC, B12 PATCH

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.

Can Vitamin B12 Deficiency Cause Brain Lesions?

Common excitotoxins

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)

Coming in Part II, find out which illnesses are linked with excitotoxins, and what you can do to prevent nerve damage…
