Vitamin b complex

Vitamin B-12 (cobalamin) plays an essential role in red blood cell formation, cell metabolism, nerve function and the production of DNA, the molecules inside cells that carry genetic information. Food sources of vitamin B-12 include poultry, meat, fish and dairy products. Vitamin B-12 is also added to some foods, such as fortified breakfast cereals, and is available as an oral supplement. Vitamin B-12 injections or nasal spray might be prescribed to treat vitamin B-12 deficiency. Vitamin B-12 deficiency is not common in the U.S. However, people who follow a vegetarian or vegan diet might be prone to deficiency because plant foods don't contain vitamin B-12. Older adults and people with digestive tract conditions that affect absorption of nutrients also are susceptible to vitamin B-12 deficiency. Left untreated, a vitamin B-12 deficiency can lead to anemia, fatigue, muscle weakness, intestinal problems, nerve damage and mood disturbances. The recommended daily amount of vitamin B-12 for adults is 2.4 micrograms. Research on the use of vitamin B-12 for specific activities and conditions shows: • Heart and blood vessel disease. Researchers had previously believed that vitamin B-12, when combined with folic acid (vitamin B-9) and vitamin B-6, might prevent diseases of the heart and blood vessels by reducing the levels of an amino acid in the blood (homocysteine). However, studies show that the combination of these vitamins doesn't seem to reduce the risk or severity of cardiov...

The confusion arises because the standard 12 content does not measure the B 12 directly. Instead, it measures a bacterial response to the food. Chemical variants of the B 12 vitamin found in plant sources are active for bacteria, but cannot be used by the human body. This same phenomenon can cause significant over-reporting of B 12 content in other types of foods as well. A common way to increase vitamin B...

You’re probably familiar with Vitamin B6 and B12, but did you know there are actually eight B vitamins? • • • • • • • • These vitamins help a variety of enzymes do their jobs, ranging from releasing energy from carbohydrates and fat to breaking down amino acids and transporting oxygen and energy-containing nutrients around the body. Spotlight on Three of the Bs: Folate, Vitamin B6, and Vitamin B12 One of the advances that changed the way we look at vitamins was the discovery that too little folate is linked to birth defects such as spina bifida and anencephaly. Folate is the natural form of vitamin B9, water-soluble and naturally found in many foods. It is also added to foods and sold as a supplement in the form of folic acid; this form is actually better absorbed than that from food sources—85% vs. 50%, respectively. Another line of research about folate and two other B vitamins, vitamin B6 and vitamin B12, explores their roles in reducing some types of cancer and heart disease. Vitamin B12, or cobalamin, is naturally found in animal foods. It can also be added to foods or supplements. Vitamin B12 is needed to form red blood cells and DNA. It is also a key player in the function and development of brain and nerve cells.

Verywell / Joshua Seong Health Benefits Each of the eight vitamins in vitamin B complex supplements has its own unique set of health benefits. For instance, vitamin B1 is critical for the growth, development, and function of cells in the body. Other vitamins, such as B2, work cooperatively in the body with other B vitamins to convert food into energy. B2 converts B6 into a usable form and aids in niacin production, which is mainly obtained from food and is essential in the proper functioning of cells. B7 helps the body convert fats, carbohydrates, and proteins from the food you eat into energy. It is also needed to make fatty acids (which help to build and sustain overall health) and maintain bone and hair health. Vitamin B9 is required to help cells produce and maintain DNA (the genetic material found in all body cells), while B12 is important for protein metabolism. Keep in mind, not everyone requires vitamin B supplementation. Speak with your health care provider if you believe supplementation may benefit you. Depending on your individual needs, your provider may advise you to take a specific B vitamin sup...

B-Complex refers to the eight B vitamins found in our diets, B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin). B vitamins are most notably involved in energy production, protein metabolism, and cell division. Lucky for us, many people can easily meet their B vitamin requirements from their diets, and there are no demonstrated benefits of getting extra B vitamins beyond the body’s requirements. People with limited diets, older adults, those with Some folks may just need to supplement with one or two B vitamins rather than taking the entire B-complex, so it is important to talk with a healthcare provider if you are thinking of supplementing with any B vitamins. When choosing a B-complex supplement, look for which B vitamins are included and the dosage of each compared to your needs, note what other ingredients the supplement contains, and aim for a supplement that is third-party tested to verify that it contains what it says it contains.
