Vitamin B12 is a complex and important B vitamin in the body.  Your personal wellness and the efficiency at which your body operates is a direct result of the quality and completeness of the nutrients you consume. Complete nutrition promotes complete wellness, nutritional deficiencies result in wellness deficiencies. Energy levels and metabolism are some of the most noticeable status indicators of wellness.

To encourage both to be at their best, special attention needs to be paid to thyroid gland health and vitamin B-12 intake. A sluggish thyroid, or hypothyroidism, may cause you to be deficient in vitamin B-12, and the resulting vitamin B-12 deficiency can further exacerbate the slow thyroid or negatively affect energy.Find out how vitamin B12 deficiency can reduce the production of thyroid hormones and how you can improve thyroid function through supplements.

Thyroid Gland and Its Function

Thyroid Gland

The thyroid gland is a small, butterfly-shap gland in the front of your neck. It’s the brain of the endocrine system and responsible for synthesizing thyroid hormones T3 and T4 which control metabolism and heartbeat. The gland secretes more thyroid hormone when you need a boost in energy, such as when you’re cold.

The hormone boost cues your body to speed up your metabolism, or the rate at which chemical reactions occur, and this generates more heat and raises your body’s temperature. Consequently, thyroid hormones affect your basal metabolic rate (BMR) and that determines how many calories you burn while you’re at rest.

Symptoms and Effects of B-12 Deficiency

The process of metabolizing vitamin B-12 is a complicated one, and there are several ways to develop a deficiency. The vitamin B-12 found naturally in food is bound to proteins. Once consumed and in the stomach, it separates from these proteins through the action of pepsin and gastric acid. From here, it immediately binds to R protein from saliva which protects it from damage in the acidic environment.

In the duodenum, the first section of the small intestine, the B-12-R protein complex splits apart. Intrinsic factor (IF), a protein secreted in the stomach, joins B-12 and safely transports it past the protein-digesting enzymes that would otherwise destroy the vitamin. Once it reaches the last part of the small intestine, the ileum, it’s absorb from the GI tract where B-12 detaches from IF and joins transcobalamin to become B-12–TC-II. This last complex is taken up by the bone marrow, liver, and other cells; the liver stores 90% of a person’s B-12.

A B-12 deficiency may result when you either don’t consume enough B-12, or your body doesn’t absorb enough B-12. Absorption issues can result from inadequate intrinsic factor, digestive enzyme issues, or organ damage. Symptoms of deficiency vary depending on severity. The most common include fatigue, constipation, decreased appetite, tingling in the hands and feet, impaired memory, depression, and soreness of the tongue.

Some people have a higher risk of B-12 deficiency:

  • Older adults, due to decreased hydrochloric acid in the stomach.
  • People whose bodies don’t produce enough intrinsic factor.
  • Vegetarians and vegans who don’t get B-12 from food.
  • People with conditions that irritate mucosal lining in the stomach and intestines, such as Crohn’s or celiac disease, chronic alcoholism, or inflammatory bowel disease

Effect of Hypothyroidism on B-12 Absorption

Hypothyroidism can compromise your ability to absorb vitamin B-12. An infection of Helicobacter pylori bacteria may also interfere with gastric secretions and hinder B-12 absorption.

Experts believe that 4.6% of the U.S. population age 12 and up suffers from hypothyroidism. One study found that approximately 40% of hyperthyroid patients also suffer from a B-12 deficiency. Adding supplementary B-12 to these patients’ routines improved weakness, memory, mood, and other symptoms. The USDA recommends B-12 supplementation for people at risk of deficiency because it’s more easy to  absorb than B-12 from food sources.

Dietary Sources of Vitamin B-12

The most common sources of B-12 are meat, seafood, eggs, and dairy.Since vitamin B-12 is produced by a soil based bacteria,[14] animals pick it up while foraging for food. Some vegetarian sources such as fortified cereals and nutritional yeast do exist if you’re trying to avoid animal products. A B-12 supplement is a great way to fill the gaps in your nutritional intake.

The Benefits of B-12 Supplementation

A B-12 supplement is invaluable, especially for older adults. The right B-12 supplement is easy to absorb and provides the B-12 the human body requires. All people at risk of B-12 deficiency should consider a B-12 supplement. VeganSafe B-12™ offers the most bioactive forms of B-12—methylcobalamin and adenosylcobalamin.
