The Basics of Vitamin B12

Are you aware of the vital role vitamin B12 plays in sustaining your health? B12 is one of several nutrients that make up the complex vitamin B. Also known as colbamin, it acts in many different ways to support your metabolism and overall health. Just some of vitamin B12’s functions include:

• Aids in the formation and regeneration of red blood cells


• Supports the health of the nervous system


• Increases energy


• Helps children grown and develop


• Facilitates the metabolism of carbohydrates, proteins and fats


• Assists with the development of DNA

Vitamin B12 Deficiency

Like all nutrients, a lack of vitamin B12 can have serious affects on the body. Deficiency results when not enough B12 is ingested or when the body is unable to absorb adequate quantities. Individuals who fail to consume enough B12 because of dietary restrictions or personal choices are at risk.

Deficiency manifests itself in a variety of ways. Common symptoms include:

• Unexplained fatigue


• Feeling dizzy or week


• Parathesia


• Deficiencies in growth among children


• Degeneration of the spinal cord


• Depression


• Loss of appetite

Deficiencies during pregnancy can be particularly harmful to the fetus, and a vitamin B12 supplement is usually recommended for pregnant or nursing women. A vitamin B12 supplement is also recommended for individuals over the age of 50. Vegetarians who follow a strict animal-food free diet and vegans may be at risk of deficiency due to their avoidance of typical sources of vitamin B12.

If you believe you are suffering from a vitamin B12 deficiency, it is important to seek medical care to restore your health. Testing can determine whether a B12 deficiency or some other condition is present. A vitamin B12 supplement may or may not correct the underlying cause of your deficiency. Medical professionals must make this determination.

Vitamin B12 Rich Foods

Many animal products contain vitamin B12, including fish and mollusks, meat, and poultry. Eggs and milk are another good source of B12. Vegetarians or lactose intolerant individuals can also consume B12 via cereals. Alternatively, a quality vitamin B12 supplement can provide the RDA of this all important nutrient.

Although vitamin B12 toxicity is rare, consuming mega-doses of this or any nutrient is ill-advised. Your doctor or a nutritionist can suggest an appropriate dosage for your vitamin B12 supplement considering your dietary intake and unique medical history.
