In the fast pace of modern society, energy is an important commodity. However, many of the methods that are used to generate an alert response are actually taxing on the body and can lead to adrenal deficiencies. Vitamin B-12 offers support for internal function and cellular growth, while also stimulating a metabolic response that results in greater physical energy. This combination has made this supplement popular for chronic fatigue conditions, although the benefits extend beyond this effect.
One of the greatest functions that Vitamin B-12 offers is to the health of the nervous system. It is integral to the health formation of nerve tissue and assists in cellular metabolism for generating stronger connections and stimulus-response throughout the body. This makes it effective in supporting people with neuralgias and for aiding cognitive processes.
Vitamin B-12 is also necessary for the healthy formation of blood cells. It has a supportive role in the manner that Iron is processed within the body, and is needed for good absorption in order to maintain cell membranes. A lack of Vitamin B-12 can cause anemia, and may also lead to spinal cord and nerve degeneration.
All these actions also affect the noticeable benefits of mental alertness and physical energy. This is also because supplemental Vitamin B-12 can aid in digestion and absorption of nutrients, so that the body is able to function efficiently. While Vitamin B-12 can be found in foods such as red meats and grains, processing and heating can diminish the amount found in these sources.
For most people, dosages around 4 mcg can prevent the symptoms of a deficiency, although people who are on a restrictive or vegetarian diet may need as much as 20 mcg to combat fatigue, anemia, and slow muscle response. In people who are generally healthy, the lower daily dosage will offer a positive boost that is also supportive of nerve growth within the body.
