Your body may need more folate than usual if you: Pregnancy If you're pregnant or trying to get pregnant, it's recommended that you take a microgram folic acid tablet every day until you're 12 weeks pregnant. This will ensure that both you and your baby have enough folate and help your baby grow and develop. Folic acid tablets are available with a prescription from your GP, or you can buy them over the counter from pharmacies, large supermarkets and health food stores. If you're pregnant and have another condition that may increase your body's need for folate, such as those mentioned above, your GP will monitor you closely to prevent you from becoming anaemic.
In some cases, you may need a higher dose of folic acid. For example, if you have diabetes, you should take a 5 milligrams 5mg supplement of folic acid instead of the standard micrograms.

This is why it's important for your symptoms to be taken into account when a diagnosis is made. A particular drawback of testing vitamin B12 levels is that the current widely-used blood test only measures the total amount of vitamin B12 in your blood. Identifying the cause If your symptoms and blood test results suggest a vitamin B12 or folate deficiency, your GP may arrange further tests. This is an autoimmune condition where your immune system produces antibodies to attack healthy cellswhich means you're unable to absorb vitamin B12 from the food you eat.

Referral to a specialist You may be referred to a specialist for further tests or treatment. Treating vitamin B12 or folate deficiency anaemia The treatment for vitamin B12 or folate deficiency anaemia depends on what's causing the condition.
Most people can be easily treated with injections or tablets to replace the missing vitamins. Treating vitamin B12 deficiency anaemia Vitamin B12 deficiency anaemia is usually treated with injections of vitamin B12, in a form called hydroxocobalamin. At first, you'll have these injections every other day for two weeks, or until your symptoms have stopped improving.
Vegans are advised to eat fortified food and take supplements. How much do I need? The UK government says adults need 1. A study published last year found one in 12 women aged between 19 and 39 were B12 deficient, despite consuming at least the UK recommended minimum intake.

What are the symptoms and causes of B12 deficiency? Symptoms include fatigue, faintness, headaches, pale skin, loss of appetite, weight loss, pins and needles and a sore, red tongue. One of the main causes is the autoimmune condition pernicious anaemia.
Researchers have also identified a gene variation linked to B12 deficiency. Long-term deficiency can lead to serious heart and neurological problems.
Am I likely to have B12 deficiency? However, some say these rates are based on deficiency thresholds that are set too low. Particularly in light of continued demands for a higher level of fortification 2324clearly defining the benefits and risks of high folic acid intake assumes vital importance. Writing about this challenge, Moore 25 observed that the current fortification program provides the perfect opportunity for epidemiologic study of the unanswered questions, including those related to the interaction between folate and vitamin B Folate status and intake in the era of folic acid fortification Mandatory folic acid fortification of enriched cereal grain products sold in the United States officially took effect in January Not surprisingly, the first report on the program's effect showed that fortification resulted in a marked increase in folate status 27 Specifically, mean plasma folate increased from 4.
Furthermore, the prevalence of folate deficiency decreased from To test the hypothesis that the high folate status achievable in the era of mandatory folic acid fortification affects the consequences of vitamin B deficiency, either by a masking phenomenon or by exacerbating neurologic effects, we used data collected in recent versions of the National Health and Nutrition Examination Survey NHANES to evaluate the interaction between high serum folate and low vitamin B status in relation to several outcomes linked to vitamin B deficiency; namely, anemia, macrocytosis, cognitive impairment, elevated homocysteine concentrations, and elevated MMA concentrations 31 We review and discuss the results of these studies here.
Of the subjects who met eligibility requirements, complete data for analyses pertaining to anemia were available for subjects, and complete data for analyses pertaining to cognitive function were available for subjects.
Demographic and health data were collected by interview, and cognitive function was assessed by using a version of the Digit Symbol-Substitution subtest of the Wechsler Adult Intelligence Scale III—a screening test designed to detect cognitive impairment in adults and children Blood samples were drawn and analyzed for biochemical markers, and a complete blood count was performed. The tabulated data show that having low vitamin B status, regardless of serum folate, was associated with a significantly increased prevalence of both anemia and cognitive impairment.
Furthermore, compared with having normal status for both vitamins, having high serum folate but normal vitamin B status was associated with a reduced prevalence of anemia and a significantly reduced prevalence of cognitive impairment.
The worst combination was low vitamin B status and high serum folate.
