Vitamin B Complex and Urine
Vitamin B complex is highly responsible for changing the color of the urine. Some members of the B complex family, like Vitamin B1 (thiamine), Vitamin B3 and Vitamin B6 (pyridoxine) are white in their natural state whereas Vitamin B12 is pink and Vitamin B2 is orange.

The kidneys process liquids or urine from whatever we eat and drink. The resulting urine consists of mainly water and dissolved waste material. It also involves various dead blood cells and other eliminated materials from body processes.

Vitamin B complex comprises of all the water soluble vitamins. These vitamins get dissolved in water and are washed out from the body in the form of urine. The excretion of B vitamins in normal growth cycle does not change the color of urine but when taken in excess riboflavin tends to change the color. If B vitamins are not consumed daily in adequate amount, it tends to cause the deficiency symptoms. These symptoms further lead to organ malfunctioning which in turn eliminates waste materials with the urine. Thus, color of the urine indicates the health condition of an individual.

The normal urine color is pale yellow.

Taking excess of Riboflavin changes the color to yellow or orange because riboflavin is orange in color. It indicates that a vitamin tablet has completely dissolved in the body. A deficiency in Vitamin B12 causes liver problems which in turn results in dark yellow urine. Excess of Vitamin B 2 can result in orange color urine. Brown urine is an indication of a serious health condition like liver disease or hepatitis, caused by deficiency of B complex Vitamin.  Urine can turn to a brighter green color in case of toxicity of B vitamins.

The color of your urine may determine your health condition. Ensure that you incorporate adequate nutrients from B group vitamins to curb the deficiency symptoms and fight diseases. If these symptoms are curbed and diseases are treated, the process of color change in your urine will automatically reduce.

Urine is the liquid waste produced in the human body. The waste disposal process helps the body get rid of excess substances from within the various parts of the body.



Waste disposal is also useful to remove toxins from the body. Urine is extracted from the blood by the kidneys. This is a continuous process that takes place throughout the day. This urine is then passed into the urinary bladder where it collects until there is a sufficient quantity to trigger the desire to urinate. Under normal health conditions, the concentration of urine determines its color. An individual who has not urinated for a long period of time will have darker colored urine. This is because some of the moisture from the urine gets absorbed back into the body. Darker colored urine may also create a burning sensation in the urethra during and after urination. Urine will be extremely light if an individual drinks lots of water and urinates regularly.



This is a better situation than one where urine is dark in color. Several health problems in the liver, kidneys and urinary system can cause darkening of urine. This is a medical symptom and must be reported to a doctor immediately as it occurs.

Vitamins and minerals are essential nutrients for the human body, even though they are consumed in small quantities. The human body is extremely complicated and has several different functions that take place at any given time. Each of these functions requires different nutrients. The consumption of vitamins is essential for the maintenance of the health of the human body. Vitamin and minerals are usually absorbed into the body from the various different foods that are consumed. However, one may not be consuming enough of certain vitamins. In this situation, the consumption of vitamin supplements may be advised.



It is best to consult with a doctor before adding vitamin supplements to one’s diet. One such group of supplements is known as Vitamin B complex.

There is an interesting link between Vitamin B complex and urine. Individuals consuming Vitamin B complex will have a bright yellow urine color when they urinate within two hours after consuming the vitamin. After this bright yellow urine color has passed, the individual will urinate normally in subsequent visits to the toilet. The reason for the bright yellow urine color is that all B complex vitamins are water soluble. The body absorbs the vitamins that it needs through the digestive system into the blood. Of these vitamins, some are absorbed and others are discarded as they are not needed. These discarded vitamins are those that cause the bright yellow urine color.

The link between Vitamin B and urine color is normal.



Any individual who has this condition should not be concerned. The link between Vitamin B and urine color is linked to the first urination that occurs after the consumption of the vitamins. If this color persists throughout the day, then the individual should consult with a doctor for a series of tests. The link between Vitamin B and urine color means that some people prefer to consume the supplement in the morning or day time so that their urine color is normal before they go to sleep.

While the consumption of Vitamin B makes urine yellow, it does not have any bad effect on the body. The body is capable of filtering out the waste or excess vitamins which is why Vitamin B makes urine yellow in the first place. Individuals consuming such vitamin supplements should consume normal amounts of water and should urinate regularly as well. It is possible that the consumption of Vitamin B along with irregular urination may cause discomfort during urination. However, this is linked to poor urination habits rather than the vitamin itself.

Reduce Homocysteine and Improve Mood and Energy with B Vtiamins!                                                                                                                                                                                                                                                                                       
        The benefits of B-complex vitamins sound almost too good to be true: improved mood, mental clarity, and energy, improved reaction time, reduced homocysteine levels, and smart nutrient effects including alertness, verbal fluency, improved concentration, mental agility, learning, and thinking.                                                       
                                                       
                       
        Yet, if you have a B vitamin deficiency, you could find yourself with any one or all of these symptoms:

•                 Depression
•                 Dry, rough, cracked, scaly skin
•                 Dull, dry hair
•                 Fatigue
•                 Headache, dizziness
•                 Poor appetite
•                 Constipation and other digestive disorders
•                 Nervousness
•                 Abnormal growth and development

        More reasons to take vitamin B-Complex

•                 If you want to make sure that you’re getting the full complex of B vitamins in scientifically chosen amounts.
•                 If you are under stress—either emotionally, physically, or mentally—your body requires more energy. And that means that you need more B vitamins to assist in the metabolic process—or the utilization of food.
•                 If you’re pregnant, adequate folic acid and B12 are vital for having a healthy baby.
•                 If you are over 50 years old, you may benefit from a supplemental boost. Up to 30% of adults aged 50 years and older may have atrophic gastritis—an increased growth of intestinal bacteria—and are consequently unable to normally absorb vitamin B12 in food. These individuals are able to absorb the vitamin B12 in dietary supplements however. Vitamin supplements and fortified foods may be the best sources of vitamin B12 for adults older than age 50 years.1
•                 If you consume a lot of carbs (including alcohol), which require a higher intake of B vitamins for proper metabolism.
•                 Some medications, including drugs used to treat diabetes and peptic ulcer disease, may decrease absorption of vitamin B12. Chronic use of those medications may result in a need for additional vitamin B12.
•                 If you want to lower your homocysteine levels. Homocysteine is an amino acid normally found in blood, but elevated levels have been linked to cardiovascular disease and stroke. In fact, a study from Norway shows that a combination of vitamin B6 and folate reduces homocysteine 32% within five weeks in healthy individuals. This has the potential to significantly lower the risk of heart attack and stroke.2

        What to look for in a superior B-Complex
        By providing scientifically chosen amounts of the B vitamins, a superior product ensures that you are receiving the correct quantities of each B vitamin to maximize the benefits and eliminate potential risks of taking too much of certain B vitamins. With most B-complex products you are stuck with equal amounts of each B vitamin, without regard for the fact that you want to take larger amounts of certain B vitamins, but smaller amounts of other B vitamins. So it’s important to read the label … in order to know what you are getting!        Can you get t oo much of a good thing?
        Riboflavin, or vitamin B2, is an essential vitamin, but almost all “broad spectrum, high potency multiples” contain levels that are far too high!
        We are all familiar with riboflavin's bright orange/yellow color, because it's the vitamin that turns our urine yellow after taking vitamin supplements. (Most B vitamins are white and do not turn urine yellow.) Most vitamins protect us from the damaging effects of the sun, but riboflavin has an undesirable property of reacting with light, causing the formation of peroxides, phototoxic compounds and DNA damage.345 In other words, too much B2 can generate free radicals in your eyes and skin when exposed to sun and light.
        This problem was first noticed in cell culture studies using excess riboflavin, and has now been demonstrated to be a cause of liver dysfunction in people fed with intravenous vitamins containing riboflavin. The riboflavin actually reacts with the light in the room, forming a variety of toxic compounds.6 Many of these phototoxic compounds are extremely damaging.
        The combination of sunlight and abnormally high tissue levels of riboflavin from excess supplementation is a potentially dangerous combination that should be avoided, and this can only be done by using a supplement that doesn't contain excessively large amounts of riboflavin far in excess of our bodies requirement. Until research has shown that higher intakes of riboflavin are safe and beneficial, we don't recommend exceeding the Recommended Daily Allowance of riboflavin by more than a few times. This would be about 5 milligrams for most people.
        Scientific studies show that the Bs provide dramatic health benefits
        Women who take multivitamins for at least 15 years may cut their risk of colon cancer by 75%. In the long-running Nurses Health Study (Annals of Internal Medicine, Feb. 1999), Edward Giovannucci, a researcher at Brigham and Women's Hospital in Boston, and his colleagues collected data on 88,756 women, including 442 who developed colon cancer during 14 years of follow-up. Women who got at least 400 micrograms of folic acid a day, from supplements or foods such as green vegetables and fortified cereals, had 31% fewer colon cancers than those who got less than 200 micrograms. Folate from food didn’t work as well as from supplements. No one knows why, although bioavailability problems may be to blame. Although only women were studied, other research suggests folic acid has similar effects in men.7
        In the same study, the researchers found that women who took multivitamins with vitamin B6 reduced their risk of heart disease by 30%.8

       
                Low levels of folic acid and vitamins B6 and B12 are risk factors for heart disease, neural tube defects, and colon and breast cancer

•                 Among postmenopausal women, intakes of folate and vitamin B12 were associated with a lower risk of breast cancer.9 Also, in several epidemiologic investigations, folate intake has appeared to reduce the elevated risk of breast cancer associated with moderate alcohol consumption, and vitamin B6 was also found to possibly reduce the risk of developing breast cancer. 10
•                 A Swedish-American study suggests that a diet supplemented with folic acid lowers the risk of early miscarriage.11 This is in addition to the 1998 finding that folic acid supplementation reduces the risk of birth defects.
•                 3 B vitamins—B6, B12, and folic acid—help prevent heart disease. The newest independent risk factor for cardiovascular disease is excess levels of homocysteine—not cholesterol. Contrary to popular belief, cholesterol does not cause heart disease. It is merely one of the many markers of the disease. In fact, it's quite possible to have a heart attack even if you have "normal" cholesterol levels.

       
                Scientists have discovered that vitamins B6, B12, and folic acid can dramatically lower homocysteine levels and reduce cardiovascular disease.

skydog

But according to research, there's a definite possibility you'll have a heart attack if you have high levels of homocysteine. What is it? Homocysteine is an amino acid derivative that's naturally found in your body. Too much of it can generate free radicals that increase injury to arterial walls, accelerate oxidation and the buildup of cholesterol in blood vessels, and set the stage for arterial and venous diseases, including stroke.12
        The good news is that scientists have discovered vitamins B6, B12, and folic acid can dramatically lower homocysteine levels.
        In 1969, Kilmer S. McCully, M.D., of Harvard Medical School found that heart patients had nearly 80% less vitamin B6 than healthy individuals. As a result of his work, he postulated that B6 might help protect the arteries from the damage that precedes heart disease.13 In addition, a deficiency of vitamin B12 is associated with elevated homocysteine levels and folic acid is essential for the proper metabolism of homocysteine.1415 It is estimated that by supplementing with only 400 mcg of folic acid daily the number of heart attacks suffered by Americans each year would be reduced by 10%. It is also estimated that individuals with low vitamin B6 levels have a five times greater risk of having a heart attack than individuals with higher B6 levels! So, be sure to take your Bs.

•                 Vitamin B1 (thiamine) deficiency was observed in patients with anorexia nervosa in a study at the Department of Psychiatry, University of Leister, U.K. The doctors concluded that supplementation may reduce some of the neuropsychiatric symptoms that accompany the disease. 16
•                 Doses of vitamin B6 up to 100 mg a day may relieve premenstrual syndrome (PMS), according to a meta-analysis of published research.
                  Researchers at North Staffordshire Hospital in Stoke-on-Trent, U.K. statistically analyzed nine studies examining the effect of vitamin B6 supplements on PMS. Another 16 published studies on the subject were deemed of low quality and were not included in the analysis. They concluded that vitamin B6 supplementation appears to relieve PMS symptoms including depression, breast tenderness, and bloating more effectively than placebo.
                  It’s important to note that doses higher than 200 mg a day may cause nerve damage. Since multivitamins and B complex supplements may contain B6, people taking a B6 supplement should make sure they are not getting too much. 17
•                 Smokers can reduce their risk of lung cancer by getting sufficient B vitamins, according to a study at Pennsylvania State University. Researchers conducted a case-control study, matching 300 randomly selected male smokers who developed lung cancer with 300 controls. Serum measurements of B vitamins and homocysteine, high levels of which are a known risk factor for some cancers, were taken at the study's inception in 1985. The results were adjusted for smoking and body-mass index; cancer patients smoked more and weighed less. In both cases and controls, half the men had inadequate serum levels of vitamin B6, 90 % were deficient in folate, and one-fourth had elevated homocysteine. The most significant finding was that men with initial serum vitamin B6 levels in the top 40 % of the group had only half the risk of getting lung cancer as the men in the lowest 20 %. Insufficient dietary vitamin B6 intake was weakly associated with lung cancer. 18

        Conclusion
        The most important thing to remember about the B vitamins is that they should all be taken together. They are so inter-dependent in function that large doses of any of them may cause a deficiency in others. So play it safe. If you are not already taking an excellent multi-vitamin/mineral supplement that contains the B vitamin complex, add a B complex supplement to your health regimen … in order to avoid health problems down the road.

关于到底如何摄取：
××××××××××××××××××××××
B Complex Vitamins are needed by the body for energy production, synthesis of hormones and blood cells, healthy nervous system function, and numerous other metabolic processes. The forms of the B Vitamins found in foods and most supplements, however, are not readily utilized by the body. They require conversion into their active forms before they can perform their functions as cofactors in biochemical reactions. Co-Enzyme B-Complex contains B Vitamins already in their active or “Coenzyme” forms. This enables the body to use them more quickly and efficiently because, once absorbed, they are transported directly to their site of action, requiring no conversion.  When a person ages, he or she may not absorb the B vitamins through the gut.  In this case, B complex injections are a good way to go.

哈哈，对于这种类似被hack 然后到处胡乱留言的account，还是不用太认真理会的好。浪费精神而已。
我也不只是单听一方面的言辞而已。
在wikipedia 还有百度里面找到了B 群维他命的daily 摄取量，我吃的品牌都没有超标就好。
营养也不是一味的讲求量多的，最重要的是适合大众，安全，有效。

    摄取量以及吸收量是有别的，所以最好是bioavailability的，不然吃了就浪费。

如果你吃的是他讲的那种牌子，不可能份量只有那么少呀？

    有人要买，也就随人啦。

抱歉，这个帖是讨论b-complex的，我们不要再谈这个牌子了。
