VITAMIN B IN-DEPTH

B vitamins are a group of water-soluble vitamins, and play essential roles in cell metabolism. There are eight B-group vitamins Vitamin B1 (Thiamin), Vitamin B2 (Riboflavin), Vitamin B3 (niacin), biotin, Vitamin B5 (Pantothenic Acid), Vitamin B6 (Pyridoxine), Folic acid, and Vitamin B12 (cyanocobalamin). The B vitamins were thought to be a single vitamin, referred to as vitamin B, but later research showed that they are chemically distinct vitamins. B vitamins are essential for growth, development, and a variety of other bodily functions. They play a major role in the activities of enzymes that regulate chemical reactions in the body, which are important in turning food into energy and other needed substances. B vitamins are essentail to maintain healthy skin, hair and muscle tone, enhance immune and nervous system function, promote cell growth and division, including that of the red blood cells.

 

BIOLOGICAL FUNCTION OF B VITAMINS

Vitamin B1 (thiamin) supports energy metabolism and nerve function. Thiamine is required by our bodies to properly use carbohydrate, enhances circulation, helps with blood formation, also required for the health of the nervous system and is used in the biosynthesis of a number of cell constituents, including the neurotransmitter acetylcholine and GABA. It is required for the manufacture of gastric acid, and therefore plays a part in digestion.

Thiamin supplementation may improve brain functions and help with depression and assist with memory and learning. In children it is required for growth and has shown some indication to assist in arthritis, cataracts as well as infertility.

Thiamin deficiency affects the cardiovascular, nervous, muscular, and gastrointestinal systems. Insufficient intake results in a disease called beriberi affecting the peripheral nervous system and/or the cardiovascular system. Significant food sources: spinach, green peas, tomato juice, watermelon, sunflower seeds, lean ham, lean pork chops, soy milk.

 

Vitamin B2 (riboflavin) supports energy metabolism, normal vision and, required for the proper development and function of the skin, lining of the digestive tract, blood cells, and many other parts of the body.

Riboflavin supplementation can be a useful adjunct to pharmacologic therapy in migraine treatment and prevention. It can also help in the prevention of cataracts.

Riboflavin deficiency include sore throat, redness and swelling of the lining of the mouth and throat, cracks or sores on the outsides of the lips and at the corners of the mouth, inflammation and redness of the tongue. A deficiency may also cause dry and scaling skin, fluid in the mucous membranes, and iron-deficiency anemia. The eyes may also become bloodshot, itchy, watery and sensitive to bright light.

Significant food sources: spinach, broccoli, mushrooms, eggs, milk, liver, oysters, clams.

 

Vitamin B3 (niacin) supports energy metabolism, skin health, nervous system and digestive system. As many as 200 enzymes require the niacin coenzymes, nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). NAD functions most often in energy producing reactions involving the degradation of carbohydrates, fats, proteins, and alcohol. NADP functions more often in biosynthetic reactions, such as in the synthesis of all macromolecules, including fatty acids and cholesterol.

Niacin supplementation in pharmacologic doses has been known to reduce serum cholesterol. It is also used along with other treatments for circulation problems, migraine headache, and dizziness. It also improves joint flexibility and reduces pain and swelling. Niacinamide is applied to the skin for treating three skin conditions called inflammatory acne vulgaris, bullous pemphigoid and granuloma annulare

The most common symptoms of niacin deficiency involve the skin, digestive system, and the nervous system. The late stage of severe niacin deficiency is known as pellagra, which causes skin irritation, diarrhea, and dementia.

Significant food sources: spinach, potatoes, tomato juice, lean ground beef, chicken breast, tuna (canned in water), liver, shrimp Biotin supports energy metabolism, fat synthesis, amino acid metabolism, glycogen synthesis.

 

Biotin is an important component of five mammalian enzymes known as carboxylases that catalyze essential metabolic reactions.

Studies have shown that supplementation with biotin and chromium picolinate can improve glucose utilization, insulin sensitivity, and may be a beneficial adjunct therapy in patients with type 2 diabetes. Biotin supplements may also be helpful in strengthening brittle nails.

Symptoms of deficiency include thinning of the hair, and red scaly rash around the eyes, nose, and mouth. Nervous system symptoms include depression, exhaustion, hallucinations, and tingling of the arms and legs. In addition biotin deficiency impairs glucose, fat and protein utilization.

Significant food sources: egg yolk, liver, and yeast. Avidin is an antimicrobial protein found in raw egg white that binds biotin and prevents its absorption. Cooking egg white denatures avidin, rendering it susceptible to digestion.

 

Vitamin B5 (Pantothenic Acid) is a component of coenzyme A that is required for chemical reactions that generate energy from food (fat, carbohydrates, and proteins). It is also required for the synthesis of essential fats, cholesterol, steroid hormones, acetylcholine, and melatonin.

Administration of oral pantothenic acid and application of pantothenol ointment to the skin have been shown to improve the wound-healing process. Pantothenic acid derivative called pantethine has been reported to lower cholesterol levels.

Naturally occurring pantothenic acid deficiency in humans is very rare and has been observed only in cases of severe malnutrition.

 

Vitamin B6 (pyridoxine) is essential for the function of approximately 100 enzymes that catalyze essential chemical reactions in the human body. Nucleic acids, heme (an iron-containing component of hemoglobin), and neurotransmitters, such as serotonin, dopamine, norepinephrine and GABA are synthesized using niacin-dependent enzymes.

Pyridoxine supplementation can reduce high blood levels of homocysteine, a substance thought to be involved in heart disease. The American College of Obstetrics and Gynecology considers pyridoxine a first-line treatment for nausea and vomiting caused by pregnancy.

Pyridoxine supplementation improves Premenstrual syndrome (PMS) symptoms such as breast pain and depression. Pyridoxine alone or combined with magnesium can decrease the risk of kidney stones in people with type I primary hyperoxaluria, a hereditary disorder. Low pyridoxine intake has been associated with impaired immune function, especially in the elderly.

Pyridoxine deficiency includes inflammation of the tongue, sores or ulcers of the mouth, and ulcers of the skin at the corners of the mouth. Severe vitamin B6 deficiency leads to irritability, depression, and confusion.

Significant food sources: bananas, watermelon, tomato juice, broccoli, spinach, acorn squash, potatoes, white rice, chicken breast.

 

Folic acid is needed for the proper development of the human body. The synthesis of the genetic material called DNA from its precursors is dependent on folate coenzymes. Folate coenzymes are also required for the metabolism of amino acids. Pregnant women take folic acid to prevent miscarriage and neural tube defects, birth defects such as spina bifida that occur when the fetus’s spine and back don’t close during development.

Administration of oral folic acid have been shown to reduce increased homocysteine levels, and decrease the risk of getting colorectal, pancreatic and cancer.

Insufficient folic acid intake has been associated with increased levels of homocysteine and abnormal blood cell division resulting in fewer but larger red blood cells, that leads to a decreased oxygen carrying capacity of the blood and may ultimately result in symptoms of fatigue, weakness, and shortness of breath.

Significant food sources: tomato juice, green beans, broccoli, spinach, asparagus, black-eyed peas, lentils, pinto and garbanzo beans.

 

Vitamin B12 is required for the proper function and development of the brain, nerves, blood cells, and many other parts of the body. It is used in new cell synthesis, helps break down fatty acids and amino acids.

Vitamin B12 supplementation have been shown to reduce increased homocysteine levels. It is also protective against dementia, decreases the risk of Alzheimer\'s disease, AMD (age-related macular degeneration), and depression.

Insufficient vitamin B12 intake has been associated with elevated homocysteine, methylmalonic acid (MMA) levels, and abnormal blood cell division resulting in fewer but larger red blood cells, that leads to a decreased oxygen carrying capacity of the blood and may ultimately result in symptoms of fatigue, weakness, and shortness of breath. Neurological symptoms of vitamin B12 deficiency include numbness and tingling of the arms and legs, difficulty walking, memory loss, mood changes, disorientation, and dementia. Studies have found as many as 30% of patients hospitalized for depression are deficient in vitamin B12. Vitamin B12 deficiency is estimated to affect 10%-15% of individuals over the age of 60.

Significant food sources: meats, poultry, fish, shellfish, milk, eggs.
