Vitamin B12 (cobalamin) deficiency is a common disorder with potential irreversible haematological and neurological consequences.. - Currently used diagnostic tests such as the evaluation of serum vitamin B12 and the Schilling test are insufficient, e.g. the positive predictive value of a low serum vitamin B12 level for actual vitamin B12 deficiency (i.e. tissue deficiency) is low.. - Insufficient availability of vitamin B12 will lead to the accumulation of methylmalonic acid and homocysteine in the body. Nearly all patients with vitamin B12 deficiency also have substantially increased levels of methylmalonic acid and homocysteine.. - New tests of serum methylmalonic acid and homocysteine are highly sensitive for vitamin B12 deficiency and may obviate the need for the somewhat cumbersome Schilling test.. Ned Tijdschr Geneeskd. 2005;149:2789-94 ...

Low cobalamin (vitamin B12) levels are frequent in the elderly. Most often they reflect a mild metabolic abnormality without clinical symptoms (subclinical cobalamin deficiency). It is unclear if these elderly people require medical intervention, unlike that small minority with clinical symptoms which can progress and create severe blood or nervous system problems. The study aims to determine if nitrous oxide (N2O), a common anesthetic agent, worsens cobalamin status in elderly patients with unrecognized subclinical cobalamin deficiency. The reason for concern is that N2O inactivates cobalamin and can aggravate the clinical picture of patients who already have clinical manifestations of cobalamin deficiency. The elderly are known to have an increased risk of developing mental changes after surgery and it may be that sometimes these result from aggravation of subclinical cobalamin deficiency.. The study recruits people over the age of 60 years who are undergoing clinically indicated elective ...

A methylmalonic acid blood test is typically used to screen for vitamin B12 deficiency. With Request A Test, ordering your Methylmalonic Acid testing couldnt be easier or more convenient. Order your lab tests, give your sample, get results.

The aims of this study were to document the levels of cobalamin, folate, methylmalonic acid (MMA) and total homocysteine (tHcy) in serum and their relations to symptoms, clinical findings, and other factors in order to improve the possibilities of detecting early deficiency of vitamin B12 or folate, and to study the effects of cobalamin and folic acid treatment over a three-year period.. The study population consisted of a 20% random sample of persons 70 years or older living in Älvkarleby in mid-Sweden. They were invited to a survey and 224 (88.4%) persons responded. Data were obtained by questionnaire, laboratory investigations and physical examination for the period 1993 - 1999.. In a multivariate analysis performed at baseline, serum MMA and tHcy were significantly and independently correlated to age, serum cobalamin, and creatinine levels, and tHcy also to sex and serum folate. Neither serum cobalamin, folate, MMA nor tHcy had any significant correlation to haemoglobin or mean red cell ...

Vegetarians who do not eat meats, fish, eggs, milk or milk products, or vitamin B12 fortified foods consume no vitamin B12 and are at high risk of developing a deficiency of vitamin B129, 25. When adults adopt a vegetarian diet, vitamin B12 deficiency symptoms can be slow to appear because it usually takes years to deplete normal body stores of vitamin B12. However, severe symptoms of vitamin B12 deficiency, most often featuring poor neurological development, can show up quickly in children and breast-fed infants of women who follow a strict vegetarian diet26.. Fortified cereals are one of the few plant food sources of vitamin B12, and are an important dietary source of vitamin B12 for vegetarians who consume no eggs, milk or milk products. Vegetarian adults who do not consume plant foods fortified with vitamin B12 need to consider taking a vitamin B12-containing supplement. Vegetarian mothers should consult with a pediatrician regarding appropriate vitamin B12 supplementation for their infants ...

Assessing vitamin B12 status. Taking a simple diet history can be a useful indicator of vitamin B12 intake and adequacy. However, laboratory analyses provide a much more accurate assessment. Measurement of serum vitamin B12 levels is a common and low-cost method of assessing vitamin B12 status. The earlier method of measuring vitamin B12 using biological assays was unreliable, as both the active and inactive analogues of vitamin B12 were detected, so levels were often overestimated.17 Modern radio isotope and immunoassay methods reliably measure biologically available analogues of vitamin B12. The early measured ranges of acceptable levels of serum vitamin B12 were determined using individuals who were apparently healthy but had potentially marginal levels of vitamin B12. This has resulted in reference intervals probably being set too low to provide a reliable clinical decision. To improve the ability to predict marginal vitamin B12 status, a higher reference interval (, 360 pmol/L) has been ...

Causes Of Vitamin B12 Deficiency. The daily requirement of vitamin B12 is 1-2 micrograms. About 5-7 micrograms of vitamin B12 is present in most types of western diet; however, many people do not eat enough of the right foods. The absorption of vitamin B12 is a complex process and the production of intrinsic acids within the stomach play a very significant role. Vitamin B12 deficiency can cause malfunction in some organs of the body.A deficiency of this vitamin can also cause some diseases, such as Megaloblastic anemia. Vitamin B12 deficiency is also known to be the cause of anemia macrocytosis. This type of anemia will result in a low white blood cell and platelet count. Vitamin B12 deficiency can also cause the irreversible death of nerve cells.. Visible Symptoms of Vitamin B12 ...

Because cobalamin deficiency is routinely treated with parenteral cobalamin, we investigated the efficacy of oral therapy. We randomly assigned 38 newly diagnosed cobalamin deficient patients to receive cyanocobalamin as either 1 mg intramuscularly on days 1, 3, 7, 10, 14, 21, 30, 60, and 90 or 2 mg orally on a daily basis for 120 days. Therapeutic effectiveness was evaluated by measuring hematologic and neurologic improvement and changes in serum levels of cobalamin (normal, 200 to 900 pg/mL) methylmalonic acid (normal, 73 to 271 nmol/L), and homocysteine (normal, 5.1 to 13.9 mmol/L). Five patients were subsequently found to have folate deficiency, which left 18 evaluable patients in the oral group and 15 in the parenteral group. Correction of hematologic and neurologic abnormalities was prompt and indistinguishable between the 2 groups. The mean pretreatment values for serum cobalamin, methylmalonic acid, and homocysteine were, respectively, 93 pg/mL, 3,850 nmol/L, and 37.2 mmol/L in the oral ...

Vitamin B12 is an essential cofactor that is integral to methylation processes important in reactions related to DNA and cell metabolism, thus a deficiency may lead to disruption of DNA and cell metabolism and thus have serious clinical consequences.1 Intracellular conversion of vitamin B12 to two active coenzymes, adenosylcobalamin in mitochondria and methylcobalamin in the cytoplasm, is necessary for the homeostasis of methylmalonic acid and homocysteine, respectively.2 3 Methylmalonic acid is converted into succinyl-CoA, of which vitamin B12 is a cofactor for the reaction. Homocysteine is biosynthesised from methionine then resynthesised into methionine or converted into amino acid cysteine. Vitamin B12 (also referred to as cobalamin) deficiency is relatively common, with important and variable clinical consequences. This review presents a concise summary of the most up to date evidence on how to diagnose and manage vitamin B12 deficiency. ...

This study was designed to assess whether symptoms, functional measures, and reported disabilities were associated with vitamin B12 (B12) deficiency when defined in three ways. Participants, aged 60 or more years of age, in 1999-2002 National Health and Nutrition Examination Surveys (NHANES) were categorized in relation to three previously used definitions of B12 deficiency: (1) serum B12 < 148 pmol/L; (2) serum B12 < 200 pmol/L and serum homocysteine > 20 μmol/L; and (3) serum B12 < 258 pmol/L or serum methylmalonic acid > 0.21 μmol/L. Functional measures of peripheral neuropathy, balance, cognitive function, gait speed, along with self-reported disability (including activities of daily living) were examined with standardized instruments by trained NHANES interviewers and technicians. Individuals identified as B12 deficient by definition 2 were more likely to manifest peripheral neuropathy OR (odds) (95% confidence intervals), p value: 9.70 (2.24, 42.07), 0.004 and report greater

MMA (Methylmalonic Acid) tests are often mentioned when B12 (and homocysteine) is discussed. Some claim that MMA tests is a gold standard for measuring B12 deficiency. Just like homocysteine, MMA is a controversial topic. Here are some links to information about MMA and MMA tests.

Anemia can also come from not having enough iron in your body. The importance of the vitamin B6 in our body is undeniable. Do your feet feel numb? Though rare, vitamin B6 deficiency can cause many health issues, with symptoms including pica, rashes, scaly and cracked lips, low mood, weakened immune system and tiredness. Muscle weakness is also a symptom of vitamin B6 deficiency and with severe vitamin B6 deficiency, convulsions are also possible. Here are 8 signs and indications that are caused due to vitamin B6 deficiency. Vitamin B6 deficiency is also found to impair the growth of white blood cells, especially in older individuals. Fruits are another major source (except for citruses like oranges and grapefruits). Taking 200mg or more a day of vitamin B6 [LK2] can lead to a loss of feeling in the arms and legs known as peripheral neuropathy. Lack of vitamin B6 can be a reason behind brain problems. Dry, Cracked Lips. Serious B6 deficiencies happen rarely. Gastrointestinal symptoms, such as ...

Other B-complex vitamins like folate, vitamin B6, and vitamin B2 are also essential for the One-carbon pathway.. 2. Vitamin B12 acts as a coenzyme in another important reaction that is needed for myelin synthesis and stabilization. Another biochemical reaction, the conversion of methylmelonyl-CoA into succinyl CoA, also requires the coenzyme cobalamin. If this reaction does not occur, methylmalonyl-CoA gets converted to methylmalonic acid (MMA), which is a myelin destabilizer. Excess MMA leads to the synthesis of abnormal fatty acids instead of myelin. These abnormal fatty acids are incorporated into neuronal lipids leading to the formation of a fragile myelin sheath. Subsequently, abnormal myelination or demyelination occurs. The result is severe central and peripheral nervous system dysfunction.. Vitamin B12 deficiency causes various neuropsychiatric problems ranging from neuropathy to dementia in the elderly. Vitamin B12 deficiency is found to cause neurological and psychiatric problems in ...

BACKGROUND: Aging is associated with a progressive decline in vitamin B-12 status. Overt vitamin B-12 deficiency causes neurologic disturbances in peripheral and central motor and sensory systems, but the public health impact for neurologic disease of moderately low vitamin B-12 status in older people is unclear. Evidence from observational studies is limited by heterogeneity in the definition of vitamin B-12 status and imprecise measures of nerve function. OBJECTIVE: We aimed to determine whether vitamin B-12 status is associated with electrophysiologic indexes of peripheral or central neurologic function in asymptomatic older people with moderately low vitamin B-12 status. DESIGN: We used a cross-sectional analysis of baseline data from the Older People and Enhanced Neurological Function study conducted in Southeast England. This trial investigated the effectiveness of vitamin B-12 supplementation on electrophysiologic indexes of neurologic function in asymptomatic older people (mean age: 80 y) with

Vitamin B12 deficiency: Find the most comprehensive real-world symptom and treatment data on vitamin B12 deficiency at PatientsLikeMe. 1,048 patients with vitamin B12 deficiency experience fatigue, pain, depressed mood, anxious mood, and insomnia and use Vitamin B12 (cyanocobalamin), Vitamin B12 Injection, Folic Acid, Tramadol, and Gabapentin to treat their vitamin B12 deficiency and its symptoms.

Vitamin B12 is essential for DNA synthesis and for cellular energy production. This review aims to outline the metabolism of vitamin B12, and to evaluate the causes and consequences of sub-clinical vitamin B12 deficiency. Vitamin B12 deficiency is common, mainly due to limited dietary intake of animal foods or malabsorption of the vitamin. Vegetarians are at risk of vitamin B12 deficiency as are other groups with low intakes of animal foods or those with restrictive dietary patterns. Malabsorption of vitamin B12 is most commonly seen in the elderly, secondary to gastric achlorhydria. The symptoms of sub-clinical deficiency are subtle and often not recognized. The long-term consequences of sub-clinical deficiency are not fully known but may include adverse effects on pregnancy outcomes, vascular, cognitive, bone and eye health.

Vitamin B12 deficiency anemia is a blood problem that occurs when there is not enough of this vitamin in the body. Vitamin B12 helps make red blood cells. Without enough vitamin B12, the body does not produce enough red blood cells, and cells throughout the body do not get the oxygen they need.. Vitamin B12 (also called cobalamin) is found in animal products such as meat, eggs, and milk products. Most people get more than enough of this vitamin from the food they eat. Vitamin B12 deficiency anemia usually occurs when the body cannot absorb this vitamin from food. It can also occur if a persons diet does not include enough of this vitamin.. A mild deficiency may not cause symptoms. As the anemia becomes worse, symptoms may include weakness, fatigue, diarrhea or constipation, numbness or tingling in the fingers and toes, poor sense of balance, thinking and memory problems, and/or depression. If the condition is not treated right away, symptoms caused by damage to the brain and nerve cells may ...

Tryptophan is a very industrious amino acid. As an essential amino acid, tryptophan must be eaten in our diet. It does its job by assisting and boosting multiple systems in our body to also do theirs. Tryptophan is the nutritional social worker in our body who helps everyone else but risks getting worn out and depleted in the process.. Once we eat tryptophan in a protein-based food, it can be converted into serotonin during the day and melatonin at night. However, the main route for tryptophan is the production of vitamin B3. In fact, more than 90% of the tryptophan we eat becomes vitamin B3 when we are stressed and have not eaten enough of this important vitamin. If we consume enough vitamin B3, the route from tryptophan to vitamin B3 is interrupted and most of the tryptophan we consume becomes serotonin and melatonin. Therefore, vitamin B3 is known as a stress vitamin.. The interesting history of tryptophan and vitamin B3 goes back more than a century, when an illness youve probably never ...

Not only is medical imaging worthless in determining which cases will benefit from Vitamin B12 therapy, but blood testing has little value either. Since the 1950s, several studies have shown that cases of dementia that respond well to vitamin B12 therapy often have completely normal Vitamin B12 blood tests. Yet 50 years later, doctors still rely EXCLUSIVELY on blood testing and medical imaging to determine the need for Vitamin B12 therapy. These studies are clearly showing that a trial regimen of high dose vitamin B12 is absolutely warranted with cases of new onset dementia regardless of the results of medical testing. Yet modern medicine is simply NOT paying attention, and this extraordinarily safe therapy that costs less than $100 is virtually NEVER instituted. As a result, Alzheimer`s patients who COULD have benefited if B12 therapy were instituted soon after diagnosis are left with no memory and no hope ...

If you think you could be suffering from a deficiency of the vitamin, you may embark on vitamin B12 supplementation a regular basis. Before embarking on an extreme plan, first get yourself investigated. The most frightening aspect of vitamin B12 overdose is that it is linked to various types of cancers. Vitamin B12 encourages cell division and it does not differentiate between healthy cells and unhealthy cells. An excess of the vitamin gives the extra energy that is required by the cancer cells. Also, no research has been able to ascertain a safe upper limit for vitamin B12 intake. ...

Vitamin B12, molecular model. Vitamin B12(cobalamin) is an essential nutrient that humans are unable to produce and need to obtain from their diet. It is found in meat, fish poultry and dairy products. Vitamin B12 is needed for producing red blood cells and for a healthy nervous system. Deficiency can lead to pernicious anaemia, with symptoms including tiredness, dizziness and a reduced sense of taste. Vitamin B12s chemical formula is C63H88CoN14O14P. Atoms are represented as spheres and are colour-coded: carbon ( grey), hydrogen (light orange), cobalt (orange), nitrogen (blue), oxygen (red) and phosphorus (green). - Stock Image F008/9419

We now know that vitamin B12 is essential for our body.. We need it for production of red blood cells, synthesis of DNA and for the proper functioning of the nervous system.. But, how does vitamin B12 perform these functions? Lets see.. Vitamin B12 plays an important role in the growth and maturation of the red blood cells, along with folic acid.. In the presence of vitamin B12, the red blood cells are able to divide, become smaller and squeeze themselves out of the bone marrow to get into circulation carrying oxygen to the different body cells.. In the absence of vitamin B12, the RBCs are still large in size and are unable to come out of the bone marrow.. They are also fragile.. Due to this, there is a decrease in RBCs and reduced oxygen transport across the body.. The RBCs are also very fragile and tend to disintegrate very easily.. The enzyme methionine synthase that converts amino acid homocysteine into methionine (needed for DNA methylation) needs methylcobalamin, one of the two forms of ...

Vitamin B1 belongs to the complex of B vitamins that are soluble. His main role is to hold a healthy nervous system and cardiovascular system. Besides that, vitamin B1 is necessary for maintaining the muscle tone and also its necessary for healthy eyes, hair, skin and liver. It helps the body to deal with stress more easily, so often people call this vitamin against stress - vitamin.. Where you can find it?. Vitamin B1 is not stored in the body so it is necessary to consume it in daily bases trough food. The riches sources with vitamin B are: integrated cereal grains, meet, especially liver. It can also be found in the grain germ, integral rise and in some fruits and vegetables: Spinach, mushrooms, lettuce, asparagus, peas, sunflower seeds and tomatoes. What if you dont consume it?. The lack of vitamin B1 can cause a variety of symptoms included: lethargy, irritability, weakened memory, lack of appetite and healthy sleep, poor digestion and sensitivity of the mucous membrane. If these ...

Vitamin B12 is a complicated vitamin with a unique absorption mechanism and a number of inactive analogues-molecules that appear to be active B12, but actually are not-that possibly interfere with its function. Vitamin B12 is generally found in all animal foods except honey. But there is no reliable B12 in Plant Foods, including tempeh, seaweeds, and organic produce. Luckily, vitamin B12 is made by bacteria and doesnt need to be obtained from animal products. Its fairly easy for most vegans to obtain a source of vitamin B12, and taking B12 on a regular basis will provide you with a B12 status equal to or superior to people who rely on animal products for B12. But what if you dont bother?. One of the earliest studies conducted on vegans, from the U.K. in 1955, found significant vitamin B12 deficiency with some suffering from nerve damage and dementia. This and many other Individual Cases of B12 Deficiency in Vegans, and a great deal of other research, has led to the overwhelming consensus in ...

Conclusion OG cancer most commonly affects people ,65 years of age. The prevalence of Vitamin B12 deficiency increases with age. This is attributed to a reduction in stomach acid and pepsin production. However the study population has a higher prevalence of Vitamin B12 deficiency than the general population (65-74 years age 1 in 6 vs 1 in 20).1Implications of deficiency include anaemia, which can have significant consequences for surgery, but also symptoms such as fatigue; depression; problems with memory and understanding; all of which can negatively impact on patients Quality of Life. Deficiency can be masked as symptoms which may be attributed to the cancer and/or its treatment. Older age, weight loss and poor nutrition can contribute to Vitamin B12 deficiency in these patients with OG cancer. However 1/5 of the deficient subgroup had stable/gained weight suggesting other possible causes of deficiency such as the use of antacid medication. The high prevalence of Vitamin B12 deficiency in ...

Summary. In a recent advertising campaign, GNC published the statement that Vegetarians and vegans are among the healthiest people in the world. [source]. Now thats truth in advertising.. However, the bold print of their advertisement reads, The only natural source of vitamin B12 comes from consuming animal products. Pictured in the ad is a cut of steak.. The clear message is that meat is our only source for Vitamin B12.. This just isnt true, and its a surprising statement coming from a company that should know better. Its also an odd contradiction to say that vegans are among the healthiest people in the world, but they dont get vitamin B12.. The fact is that non-meat sources of Vitamin B12 include milk, whey, yogurt, cheese, and eggs. In addition, yeast extracts are considered a good vegan source of Vitamin B12.. ...

The experimental rations commonly used in studies on the vitamin B2 complex are, as a rule, low in content of choline.. Addition of vitamin B6 has an aggravating influence on the specific effect of deficiency of choline, especially with regard to the development of cortical necrosis of the kidneys.. The acute and subacute lesions associated with this specific type of renal injury are described.. The renal lesions and fat infiltration of the liver, observed in rats kept on a vitamin B free diet, supplemented with thiamine, riboflavin and vitamin B6, are indistinguishable from those attributed hitherto to cystine intoxication.. Attention is drawn to the rôle of choline as a potential member of the vitamin B2 complex and, in this connection, to the importance of the ratio cystine/methionine in the diet.. ...

Oily fish is a rich source of vitamins B2 and is also rich in omega-3 fatty acids. Amongst the different fishes, mackerel is the best source of vitamin B2. A 100 gram serving of mackerel provides 0.58 mg or 34% DV of this vitamin B2. Other oily fish also contain significant amounts of vitamin B2. These fish are smoked salmon (27% DV), wild salmon (24% DV), trout (21% DV), tuna and herring (15% DV) and salmon (11% DV) in a 3 oz. serving. So, if you want to take the proper amount of vitamin B2 ensure to have fish at least once in a week.. ...

In a new study from the United Kingdom, researchers found that more than half of vegan men were deficient in vitamin B12 based on their serum levels. The findings are part of the EPIC-Oxford study and will be published in the European Journal of Clinical Nutrition.. The researchers looked at diets and serum levels of B12 in 226 omnivores, 231 vegetarians and 232 vegans. Mean serum B12 levels in vegans were 33% lower than in the vegetarians and 57% percent lower than in the omnivores.. In addition, the vegans had much higher serum levels of folate-not surprising since vegan diets are typically high in this nutrient. Since folate can mask B12-deficiency anemia, there are concerns about diets that are low in B12 and high in folate.. One especially unfortunate finding: Only 19% of the vegan men said they took vitamin B12 supplements. And surprisingly, their serum levels of vitamin B12 were no higher than those of vegan men who didnt take supplements.. Why are some vegans not getting adequate ...

It was in 1930 that L. Wills discovered the existence of severe anemia common to many pregnant women from disadvantaged backgrounds in some parts of India. The link between diet and this type of megaloblastic anemia is thus established. This form of anemia will be treated by adding yeast to the diet.. Later, researchers will be able to isolate vitamin B9 from certain foods (liver, vegetables, etc.). Therefore, the study of this nutrient will reveal its many roles in maturation and cell renewal.. It was only in 1980 that scientists were able to establish a clear link between vitamin B9 deficiency and Spina Bifida. These findings will quickly lead to the first recommendations for vitamin B9 supplementation during pregnancy. ...

Iron deficiency is the most common cause of anemia in pregnancy. Pregnant women with anemia are, in general, exclusively treated with iron supplementation.
