Boost your Metabolism with Vitamin B12

Wednesday, June 19th, 2013



If you’ve been feeling tired and mental unfocused lately, you may just need to give your metabolism a boost with some extra vitamin B12. Difficulty losing weight, brain fog, and extreme fatigue are all signs of a sluggish metabolism that can be helped by replenishing your body’s healthy stores of vitamin B12.

Boost your Metabolism with Vitamin B12

Why B12?

Vitamin B12 is one of the most essential nutrients for allover health; it helps to boost energy, promote cellular activity, protect the nervous system, and delay many of the effects of aging.

For metabolism, vitamin B12 helps by enhancing cell growth, enabling your body to build DNA more efficiently, in addition to sustaining red blood cell production needed for oxygen.

Hypothyroidism and vitamin B12

If you suffer from slow metabolism due to hypothyroidism, then you may be more prone to vitamin B12 deficiency than people without thyroid disorders.

And the symptoms of hypothyroidism- chronic fatigue, brain fog, and slow metabolism- actually mimic typical signs of vitamin B12 deficiency, making it all that much harder to diagnose vitamin B12 deficiency in people with underactive thyroids.

How much vitamin B12 do I need?

The standard dose is 1,000mcg of vitamin B12, to be taken as advised by your physician, or as needed.

Vitamin B12 is safe to take in any amount, and many studies confirm the healthy benefits of taking mega-doses for energy, good mood, and fit thinking skills.

If your vitamin B12 levels are very low, then you may need to take weekly supplements for a while, and then continue with monthly doses of vitamin B12.

Boost your metabolism with these tips.

In addition to taking vitamin B12 for energy and maintaining a healthy weight, you should also follow these simple guidelines for metabolic integrity:

  • Eat a healthy balanced breakfast every day, in order to prevent going into metabolic starvation mode.
  • Eat small regular meals throughout the day to keep your metabolism running smoothly.
  • Exercise every day for at least thirty minutes, and you’ll be rewarded with hours of increased energy for the rest of that day.
  • Drink cold water throughout the day, not just to prevent fatigue from dehydration, but also because ice water increases energy and promotes a healthy metabolic rate.

Low B12 means Low Thyroid- Hypothyroidism and B12 Deficiency

Tuesday, November 8th, 2011



Being tired all the time is a symptom of B12 deficiency, but it can also signal hypothyroidism (low thyroid), a thyroid disease that occurs with low B12 levels.  Because hypothyroid symptoms are similar, vitamin B12 deficiency often goes undetected.


B12 deficiency causes fatigue, depression, and other mood disorders often associated with an underactive thyroid. If you’ve been diagnosed with thyroiditis, then it’s also important also to recognize the symptoms of B12 deficiency, and know whether you might require more vitamin B12 (cobalamin).

What is hypothyroidism?

Hypothyroidism is an autoimmune thyroid disease (AITD) that occurs in the thyroid gland, causing inflammation, and reducing its ability to produce sufficient amounts of thyroid hormones.
Hashimoto’s disease is one example of thyroiditis that causes low thyroid levels.  

Sometimes, thyroid treatment for hyperthyroidism (overactive thyroid), such as radioactive iodine or surgery, can backfire, causing underactive thyroid symptoms.

Why am I always tired?  Symptoms of hypothyroidism

Symptoms of low thyroid include:

  • Empty facial expressions
  • Husky, gravelly voice
  • Chronic fatigue, tiredness
  • Sluggish, droning speech patterns
  • “Brain fog,” or confusion
  • Depression
  • Uncontrolled weight gain
  • Droopy eyelids
  • Puffy, bloated face
  • Constipation
  • Diarrhea
  • Dry skin and hair
  • Sparse hair, including eyebrows
  • Tingling and numbness in the hands and feet
  • Muscular pain
  • Feebleness
  • Slow resting heart rate
  • Orange-colored skin on the hands and feet
  • Heavy menstrual periods in women

Vitamin B12 deficiency symptoms

Vitamin B12 is a water-soluble nutrient that is responsible for making red blood cells, controlling DNA synthesis, regulating the nervous system, and improving cognitive functioning.  Without proper levels of vitamin B12, you may suffer neurological damage, dementia, or heart attack resulting from elevated homocysteine levels.

Low B12 symptoms include:

  • Depression
  • Chronic fatigue, tiredness
  • Anxiety
  • Short-term memory loss
  • “Brain fog,” or confusion
  • Difficulty concentrating
  • Neurosis
  • Altered taste perception
  • Swollen, red tongue
  • Tingling and numbness in the hands and feet
  • Awkward hand movements
  • Loss of balance
  • Clumsiness and stumbling
  • Sleep problems

Thyroid disease and low B12 levels

In a study conducted in Sapir Medical Center, Kfar Saba, Israel, patients with autoimmune thyroid disease received blood screening for vitamin B12 deficiency.  Researchers noted a significantly high percentage of people with AITD who also had vitamin B12 deficiency caused by pernicious anemia, a disease that inhibits proper absorption of vitamin B12.

Another study conducted in Pakistan by Aga Khan University produced similar results; namely, a 40% prevalence of vitamin B12 deficiency among patients with hypothyroidism.

Hypothyroidism treatment

If you are a patient of hypothyroidism, then physicians strongly recommend routine blood testing for vitamin B12 deficiency, regardless of thyroid hormone levels.
