Vitamin B12 (Cobalamin)



Vitamin B12 deficiency is quite common in the elderly, vegetarians, vegans, smokers and alcoholics, but its prevalence may be increasing because of modern diets and lifestyle factors and especially vegetarianism and chronic mercury toxicity. A functional deficiency underlies various cardiovascular and neurological diseases, resulting in ataxia (shaky movements and unsteady gait), muscle weakness, faintness and fatigue, lethargy, weight loss, spasticity, incontinence, hypotension, vision problems, irritability, mood disturbances, dementia, psychoses, and even megaloblastic anaemia.

The body stores several years supply of this vitamin so deficiency takes some time to establish itself. If not treated, vitamin B12 deficiency can potentially cause severe and irreversible damage especially to the central nervous system. If Vitamin B12 deficiency is allowed to become chronic it may result in the accumulation of the toxin homocysteine which has been implicated in a variety of neurological and cardiovascular diseases including atherosclerosis, myocardial infarction, stroke and cognitive impairment, dementia, Parkinson’s disease, multiple sclerosis, epilepsy, and eclampsia.

About Vitamin B12 (Cobalamin)

Vitamin B12 deficiency is becoming more common due to modern diets and dietary exclusionism, and lifestyle factors which directly deplete the vitamin and include excess consumption of alcohol, smoking, chronic mercury toxicity from dental amalgam and thimerosal based vaccinations, the use of vitamin-depleting pharmaceutical drugs, and mal-absorptive bowel disorders.

Vitamin B12 is essential for methylation reactions in the body, the production of vital neurotransmitters in the brain, the maintenance of the myelin sheath on nerves, the production of red blood cells, and the formation of nucleic acids like DNA and RNA. Vitamin B12 deficiency is associated with symptoms of ataxia such as shaky movements and unsteady gait, muscle weakness, faintness and fatigue, spasticity, incontinence, hypotension, vision problems, irritability, mood disturbances, dementia, psychoses, and even megaloblastic anaemia. It may also underlie various inflammatory and cardiovascular states like skin conditions, asthma, high cholesterol, and heart disease. It is also implicated in neurological diseases like neuralgia, neuropathy, diabetic neuropathy, neuromuscular degeneration, chronic fatigue syndrome, sleep disorders, depression, dementia, and Alzheimer’s disease.

These conditions often get misdiagnosed as illnesses in their own right by doctors and psychiatrists unfamiliar with this simple biochemical imbalance and they may resort to prescribing pharmaceutical drugs to manage symptoms without addressing the underlying cause. Vitamin B12 deficiency responds well to the introduction of activated coenzyme form of vitamin B12 like methylcobalamin, 5-deoxyadenosylcobalamin, adenosylcobalamin, and dibencozide.

  • I have been using Nutrivitality Immune Support for around 6 months. I feel it has made a difference to my immune system as I’ve managed to get through the dreadful cold season without getting a cold – very unusual for me! I would definitely recommend Nutrivitality.

  • I’m a busy primary school teacher with a young family at home. Through the autumn and winter I often succumb to the odd cold and sometimes tonsillitis – a teacher is useless without her voice! Taking Nutrivitality Immune Support has helped me to keep going and avoid all the bugs the children bring in!

    - Sally
  • I run two businesses; a training company and a property business. They are both very demanding of time, typically I work around 50-60 hours per week. Since using Nutrivitality I have noticed a difference in my energy levels, which has been great as it's allowed me to keep going and be more productive for longer.

    - Charles
  • I started taking Nutrivitality every day to help prevent colds and found it to be very effective. I am eighty-seven years of age and so I need some help during the long winter months. I now have less colds and those I've had have been less severe and have cleared up quickly. Also, my general health has been much better.
