what does vitamin b6 do for your body?
445567
Vitamin B6 is needed by the body to break down a substance called homocysteine, which can directly damage blood vessel walls. Individuals who suffer a heart attack despite having normal or even low cholesterol levels are often found to have high levels of homocysteine. Since high homocysteine levels are signficantly associated with increased risk of heart attack and stroke, having a good supply of vitamin B6 on hand makes a great deal of sense. High intakes of vitamin B6 have also been shown to reduce the risk of heart disease.\n\nVery high levels of vitamin B6 can damage sensory nerves, leading to numbness in the hands and feet as well as difficulty in walking; supplementation should be stopped if these symptoms develop after beginning vitamin B6 supplementation. Vitamin B6 is usually safe in amounts of 200 to 500 mg per day, although occasional problems have been reported in this range. Higher amounts are clearly toxic

Niacin, also known as nicotinic acid or vitamin B3, is a water-soluble vitamin whose derivatives such as NADH play essential roles in energy metabolism in the living cell and DNA repair. The designation vitamin B3 also includes the amide form, nicotinamide or niacinamide. Severe lack of niacin causes the deficiency disease pellagra, whereas a mild deficiency slows down the metabolism, which in turn decreases cold tolerance and is a potential contributing factor towards obesity.

Quite the opposite.  The B vitamins are known to have a sedative effect on the nerves. \n\nVitamin B6 supplements of 50 to 100 milligrams/day can help to prevent insomnia. A tablespoon or two of nutritional yeast is an excellent Source of vitamin B6. Stir it into a glass of juice.\n\nVitamin B12 is another important supplement for treating insomnia. 25 milligrams of vitamin B12, supplemented with 100 milligrams of pantothenic acid (B5) can serve as an effective anti-insomnia vitamin regimen.\n\nAre you taking a multi-vitamin?  They sometimes have niacin, which will keep you awake.

Yes.  Taking too much of anything can hurt your body.  There are two types of vitamins: water-soluble vitamins and fat-soluble vitamins.  If the vitamin is water-soluble (e.g. vitamin C), it would take a lot of it to hurt your body, because it dissolves in water and will be excreted during urination.  However, if the vitamin is fat-soluble, it will be absorbed into your fat and remain in your body for a while.  Too much of a fat-soluble vitamin will be toxic.  That's why you should follow the "percentage of recommended daily intake" label on the side of the bottle.

it is B-12. B group vitamins are for energy, so i guess they could be used to treat fatigue.

Your body is like a dam when it comes to vitamins. First you have to fill it, then everything runs over the top or through it in the case of your body.  It is said that in America we have the most expensive urine in the world. This is becasuse of all the vitamin supplements we consume.  Make sure to drink lots of water with the vitamins you take.  Our bodies are 70% water. Not 70% coffee or 70% cola.

I believe that the vitamin niacin acts as a coenzyme in the electron transport system of cellular respiration in aerobes. This system is a major producer of ATP . A niacin defficiency would therefore cause an individual to experience early fatigue during exertion.

Functions\nVitamin B12's primary functions are in the formation of red blood cells and the maintenence of a healthy nervous system. B12 is necessary for the rapid synthesis of DNA during cell division. This is especially important in tissues where cells are dividing rapidly, particularly the bone marrow tissues responsible for red blood cell formation. If B12 deficiency occurs, DNA production is disrupted and abnormal cells called megaloblasts occur. This results in anaemia. Symptoms include excessive tiredness, breathlessness, listlessness, pallor, and poor resistance to infection. Other symptoms can include a smooth, sore tongue and menstrual disorders. Anaemia may also be due to folic acid deficiency, folic acid also being necessary for DNA synthesis. \nB12 is also important in maintaining the nervous system. Nerves are surrounded by an insulating fatty sheath comprised of a complex protein called myelin. B12 plays a vital role in the metabolism of fatty acids essential for the maintainence of myelin. Prolonged B12 deficiency can lead to nerve degeneration and irreversible neurological damage. \n\nWhen deficiency occurs, it is more commonly linked to a failure to effectively absorb B12 from the intestine rather than a dietary deficiency. Absorption of B12 requires the secretion from the cells lining the stomach of a glycoprotein, known as intrinsic factor. The B12-intrinsic factor complex is then absorbed in the ileum (part of the small intestine) in the presence of calcium. Certain people are unable to produce intrinsic factor and the subsequent pernicious anaemia is treated with injections of B12. \n\nVitamin B12 can be stored in small amounts by the body. Total body store is 2-5mg in adults. Around 80% of this is stored in the liver. \n\nVitamin B12 is excreted in the bile and is effectively reabsorbed. This is known as enterohepatic circulation. The amount of B12 excreted in the bile can vary from 1 to 10ug (micrograms) a day. People on diets low in B12, including vegans and some vegetarians, may be obtaining more B12 from reabsorption than from dietary sources. Reabsorption is the reason it can take over 20 years for deficiency disease to develop in people changing to diets absent in B12. In comparison, if B12 deficiency is due to a failure in absorption it can take only 3 years for deficiency disease to occur. \n\nDietary Sources\nThe only reliable unfortified sources of vitamin B12 are meat, dairy products and eggs. There has been considerable research into possible plant food sources of B12. Fermented soya products, seaweeds and algae have all been proposed as possible sources of B12. However, analysis of fermented soya products, including tempeh, miso, shoyu and tamari, found no significant B12. \nSpirulina, an algae available as a dietary supplement in tablet form, and nori, a seaweed, have both appeared to contain significant amounts of B12 after analysis. However, it is thought that this is due to the presence of compounds structurally similar to B12, known as B12 analogues. These cannot be utilised to satisfy dietary needs. Assay methods used to detect B12 are unable to differentiate between B12 and it's analogues, Analysis of possible B12 sources may give false positive results due to the presence of these analogues. \n\nResearchers have suggested that supposed B12 supplements such as spirulina may in fact increase the risk of B12 deficiency disease, as the B12 analogues can compete with B12 and inhibit metabolism. \n\nThe current nutritional consensus is that no plant foods can be relied on as a safe source of vitamin B12. \n\nBacteria present in the large intestine are able to synthesise B12. In the past, it has been thought that the B12 produced by these colonic bacteria could be absorbed and utilised by humans. However, the bacteria produce B12 too far down the intestine for absorption to occur, B12 not being absorbed through the colon lining. \n\nHuman faeces can contain significant B12. A study h

Taking a multi-vitamin should be in addition to healthy eating. It helps you to get nutrients that you might not get in the foods you normally eat. \n\nIn order to get more veggies into your diet why not eat salads with your meals, slide extra veggies into your recipes and choose them for snacks.

What it does?\n\nAlpha-lipoic acid affects nearly every cell in the body. It assists all of the B vitamins -- including thiamin, riboflavin, pantothenic acid, and niacin -- in converting carbohydrates, protein, and fats found in foods into energy the body can store and later use. Alpha-lipoic acid is a cell-protecting antioxidant that may help the body recycle other antioxidants, such as vitamins C and E, boosting their potency. Thanks to its unique chemical properties, alpha-lipoic acid is easily absorbed by most tissues in the body, including the brain, nerves, and liver, making it valuable for treating a wide range of ailments. \n\nForms: Tablet, and Capsule\nAlpha-lipoic acid can be purchased as an individual supplement or part of a general antioxidant booster, along with vitamins C, E, and other antioxidants. Look for it on the ingredients list; it may also be called thioctic acid. \n\nCommon Uses-\nHelps treat numbness, tingling, and other symptoms of nerve damage in people with diabetes or other conditions. \nProtects the liver in hepatitis, alcohol abuse, or exposure to poisons or toxic chemicals. \nAids in preventing cataracts. \nMay help preserve memory in Alzheimer's disease. \nServes as a high-potency antioxidant and possible immune booster, combating a wide range of disorders, including psoriasis, fibromyalgia, and AIDS. \n\nDosage: To treat specific disorders: \nAlpha-lipoic acid is usually taken in doses of 100 to 200 mg three times a day. \nFor general antioxidant support: Lower doses of 50 to 150 mg a day may be used.\n\nGuidelines for use: Alpha-lipoic acid can be taken with or without food. No major adverse effects have been reported.\n\nPossible side effects:\nAlpha-lipoic acid appears to be very safe, and there have been no reports of serious side effects in people taking it. Occasionally, the supplement may produce mild gastrointestinal upset, and in rare cases, allergic skin rashes have occurred. If side effects appear, lower the dose or discontinue using the supplement\n\nWarnings:\n\nFor people with diabetes, the use of alpha-lipoic acid may require a change in insulin or other medications. \nReminder: If you have a medical condition, talk to your doctor before taking supplements.
