Still, not all women of reproductive Supplementatipn are getting the recommended amount of Supplementation acid. This puts them at higher risk for having a baby affected by a neural tube defect.
Additional public health interventions targeting these women could help further reduce the number of neural tube defects that occur each year.
What are the differences between voluntary and mandatory fortification? Voluntary fortification allows food manufacturers to add vitamins or minerals, or both, to foods, as long as they abide by the Food and Drug Administration FDA food additive regulations.
Mandatory fortification requires food manufacturers to add certain vitamins or minerals, or both, to specified foods. Mandatory fortification is done to address a significant public health need.
For example, in the s, the FDA required addition of several B vitamins—thiamin, riboflavin, and niacin—to flour to eliminate these vitamin deficiencies in the U. Inthe FDA required that the B vitamin, folic acidbe added to enriched cereal grain products to reduce the risk of neural tube defects.
How much folic acid does an adult consume from foods that are required to be fortified? On average, an adult in the United States consumes about micrograms of folic acid each day from enriched cereal grain products How much folic acid does an adult consume from foods that are voluntarily fortified?
In addition to the approximate micrograms mcg of folic acid consumed each day from enriched cereal grain productsadults can get up to mcg daily from several ready-to-eat breakfast cereals that are voluntarily fortified by the manufacturer.
Which populations are folic acid supplementation and fortification designed to reach? Folic acid supplementation and fortification are designed to reach women of reproductive age to help prevent neural tube defects.
Why do the folic acid recommendations include the use of supplements or fortification? The use of dietary supplements and consuming fortified foods can provide the amount of folic acid needed for the prevention of neural tube defects.
A woman of reproductive age can decide to take a supplement containing folic acid or to eat foods fortified with folic acid, or both, depending on her dietary habits. What are the differences between supplementation and fortification? A dietary supplement can provide the full recommended amount of folic acid to a woman of reproductive age to help prevent her baby from having a neural tube defect.
However, this approach requires remembering to take the supplement every day. Moreover, while they are relatively inexpensive, supplements can be costly for some women. With mandatory fortification of staple foodsa large proportion of the population is getting more folic acid; therefore, getting enough folic acid to prevent neural tube defects does not require behavior change such as taking a daily vitamin.
Additionally, the added cost to the consumer for fortified food products is low How have supplementation and fortification affected the number of babies born each year with neural tube defects?
Consuming folic acid from fortified foods and vitamin supplements has been proven to prevent neural tube defectswhich can be fatal or cause varying degrees of disability. Since fortification started in the United States inand with the use of folic acid supplements, on average, 1, babies are born each year without a neural tube defect who might otherwise have had a neural tube defect.

: Supplementation| Supplementation | Creatine deficiency syndromes are a group of inborn errors e. Individuals with creatine synthesis deficiencies have low levels of creatine and PCr in the muscle and the brain. For this reason, a number of studies have investigated the use of relatively high doses of creatine monohydrate supplementation e. These studies generally show some improvement in clinical outcomes particularly for AGAT and GAMT with less consistent effects on CRTR deficiencies [ ]. For example, Battini et al. Stockler-Ipsiroglu and coworkers [ ] evaluated the effects of creatine monohydrate supplementation 0. The median age at treatment was The researchers found that creatine supplementation increased brain creatine levels and improved or stabilized clinical symptoms. Moreover, four patients treated younger than 9 months had normal or almost normal developmental outcomes. Long-term creatine supplementation has also been used to treat patients with creatine deficiency-related gyrate atrophy [ , , , , ]. These findings and others provide promise that high-dose creatine monohydrate supplementation may be an effective adjunctive therapy for children and adults with creatine synthesis deficiencies [ 18 , , , , ]. Additionally, these reports provide strong evidence regarding the long-term safety and tolerability of high-dose creatine supplementation in pediatric populations with creatine synthesis deficiencies, including infants less than 1 year of age [ ]. A total of 1, patients took an average of 9. Results revealed no clinical benefit on patient outcomes in patients with PD or ALS. However, there was some evidence that creatine supplementation slowed down progression of brain atrophy in patients with HD although clinical markers were unaffected. Creatine and phosphocreatine play an important role in maintaining myocardial bioenergetics during ischemic events [ 33 ]. In a recent review, Balestrino and colleagues [ 33 ] concluded that phosphocreatine administration, primarily as an addition to cardioplegic solutions, has been used to treat myocardial ischemia and prevent ischemia-induced arrhythmia and improve cardiac function with some success. They suggested that creatine supplementation may protect the heart during an ischemic event. A growing collection of evidence supports that creatine supplementation may improve health status as individuals age [ 41 , 43 , 44 , 45 , ]. Creatine supplementation significantly decreased HbA1c and glycemic response to standardized meal as well as increased GLUT-4 translocation. These findings suggest that creatine supplementation combined with an exercise program improves glycemic control and glucose disposal in type 2 diabetic patients. Candow and others [ ] reported that low-dose creatine 0. Similarly, Chilibeck et al. A recent meta-analysis [ 80 ] of elderly individuals 64 years participating in an average of These findings were corroborated in a meta-analysis of elderly participants 64 years who experienced greater gains in muscle mass and upper body strength with creatine supplementation during resistance-training compared to training alone [ 37 ]. These findings suggest that creatine supplementation can help prevent sarcopenia and bone loss in older individuals. For example, Watanabe et al. Since creatine uptake by the brain is slow and limited, current research is investigating whether dietary supplementation of creatine precursors like GAA may promote greater increases in brain creatine [ , ]. Since creatine supplementation has been shown to improve brain and heart bioenergetics during ischemic conditions and possess neuroprotective properties, there has been recent interest in use of creatine during pregnancy to promote neural development and reduce complications resulting from birth asphyxia [ , , , , , , , , , ]. The rationale for creatine supplementation during pregnancy is that the fetus relies upon placental transfer of maternal creatine until late in pregnancy and significant changes in creatine synthesis and excretion occur as pregnancy progresses [ , ]. Consequently, there is an increased demand for and utilization of creatine during pregnancy. Maternal creatine supplementation has been reported to improve neonatal survival and organ function following birth asphyxia in animals [ , , , , , , ]. Human studies show changes in the maternal urine and plasma creatine levels across pregnancy and association to maternal diet [ , ]. Consequently, it has been postulated that there may be benefit to creatine supplementation during pregnancy on fetal growth, development, and health [ , ]. This area of research may have broad implications for fetal and child development and health. Since creatine monohydrate became a popular dietary supplement in the early s, over 1, studies have been conducted and billions of servings of creatine have been ingested. The only consistently reported side effect from creatine supplementation that has been described in the literature has been weight gain [ 5 , 22 , 46 , 78 , 91 , 92 , ]. Available short and long-term studies in healthy and diseased populations, from infants to the elderly, at dosages ranging from 0. Additionally, assessments of adverse event reports related to dietary supplementation, including in pediatric populations, have revealed that creatine was rarely mentioned and was not associated with any significant number or any consistent pattern of adverse events [ , , ]. Unsubstantiated anecdotal claims described in the popular media as well as rare case reports described in the literature without rigorous, systematic causality assessments have been refuted in numerous well-controlled clinical studies showing that creatine supplementation does not increase the incidence of musculoskeletal injuries [ 22 , , , ], dehydration [ , , , , , , , ], muscle cramping [ 76 , , , , ], or gastrointestinal upset [ 22 , , , ]. Nor has the literature provided any support that creatine promotes renal dysfunction [ 22 , 51 , 85 , , , , , , , , , ] or has long-term detrimental effects [ 22 , 23 , 53 , , ]. Rather, as noted above, creatine monohydrate supplementation has been found to reduce the incidence of many of these anecdotally reported side effects. These reports prompted some concern that creatine supplementation may impair renal function [ , , , ] and prompted a number of researchers to examine the impact of creatine supplementation on renal function [ 22 , 51 , 85 , , , , , , , , , , , , ]. Likewise, Baracho and colleagues [ ] reported that Wistar rats fed 0, 0. Kreider et al. Gualono and associates [ ] reported that 12 weeks of creatine supplementation had no effects on kidney function in type 2 diabetic patients. While some have suggested that individuals with pre-existing renal disease consult with their physician prior to creatine supplementation in an abundance of caution, these studies and others have led researchers to conclude that there is no compelling evidence that creatine supplementation negatively affects renal function in healthy or clinical populations [ 5 , 6 , 22 , 53 , , , ]. Performance-related studies in adolescents, younger individuals, and older populations have consistently reported ergogenic benefits with no clinically significant side effects [ 5 , 6 , 22 , 23 , 53 , , , , , ]. The breadth and repetition of these findings provide compelling evidence that creatine monohydrate is well-tolerated and is safe to consume in healthy untrained and trained individuals regardless of age. Some critics of creatine supplementation have pointed to warnings listed on some product labels that individuals younger than 18 years of age should not take creatine as evidence that creatine supplementation is unsafe in younger populations. These studies provide no evidence that use of creatine at recommended doses pose a health risk to individuals less than 18 years of age. For this reason, it is our view that creatine supplementation is an acceptable nutritional strategy for younger athletes who: a. are consuming a well-balanced and performance enhancing diet; c. are knowledgeable about appropriate use of creatine; and d. do not exceed recommended dosages. After reviewing the scientific and medical literature in this area, the International Society of Sports Nutrition concludes the following in terms of creatine supplementation as the official Position of the Society:. Creatine monohydrate is the most effective ergogenic nutritional supplement currently available to athletes with the intent of increasing high-intensity exercise capacity and lean body mass during training. Creatine monohydrate supplementation is not only safe, but has been reported to have a number of therapeutic benefits in healthy and diseased populations ranging from infants to the elderly. If proper precautions and supervision are provided, creatine monohydrate supplementation in children and adolescent athletes is acceptable and may provide a nutritional alternative with a favorable safety profile to potentially dangerous anabolic androgenic drugs. However, we recommend that creatine supplementation only be considered for use by younger athletes who: a. At present, creatine monohydrate is the most extensively studied and clinically effective form of creatine for use in nutritional supplements in terms of muscle uptake and ability to increase high-intensity exercise capacity. The addition of carbohydrate or carbohydrate and protein to a creatine supplement appears to increase muscular uptake of creatine, although the effect on performance measures may not be greater than using creatine monohydrate alone. The quickest method of increasing muscle creatine stores may be to consume ~0. Initially, ingesting smaller amounts of creatine monohydrate e. Clinical populations have been supplemented with high levels of creatine monohydrate 0. Further research is warranted to examine the potential medical benefits of creatine monohydrate and precursors like guanidinoacetic acid on sport, health and medicine. Creatine monohydrate remains one of the few nutritional supplements for which research has consistently shown has ergogenic benefits.

However, this indicator has poor specificity because it is influenced by other factors, such as low folate levels and, especially, by declines in kidney function [ 6 ]. Intake recommendations for vitamin B12 and other nutrients are provided in the Dietary Reference Intakes DRIs developed by the Food and Nutrition Board FNB at the National Academies of Sciences, Engineering, and Medicine [ 1 ]. DRI is the general term for a set of reference values used for planning and assessing nutrient intakes of healthy people. These values, which vary by age and sex, include the following:. Table 1 lists the current RDAs for vitamin B12 [ 1 ]. For adults, the main criterion that the FNB used to establish the RDAs was the amount needed to maintain a healthy hematological status and serum vitamin B12 levels. For infants age 0 to 12 months, the FNB established an AI that is equivalent to the mean intake of vitamin B12 in healthy, breastfed infants. Vitamin B12 is present in foods of animal origin, including fish, meat, poultry, eggs, and dairy products [ 5 , 12 ]. Plant foods do not naturally contain vitamin B However, fortified breakfast cereals and fortified nutritional yeasts are readily available sources of vitamin B12 that have high bioavailability [ 13 , 14 ]. The average vitamin B12 level in the breast milk of women with vitamin B12 intakes above the RDA is 0. The U. Food and Drug Administration FDA specifies that infant formulas sold in the United States must provide at least 0. The estimated bioavailability of vitamin B12 from food varies by vitamin B12 dose because absorption decreases drastically when the capacity of intrinsic factor is exceeded at 1—2 mcg of vitamin B12 [ 17 ]. Bioavailability also varies by type of food source. FDA developed DVs to help consumers compare the nutrient contents of foods and dietary supplements within the context of a total diet. The DV for vitamin B12 is 2. FDA does not require food labels to list vitamin B12 content unless vitamin B12 has been added to the food. Vitamin B12 levels are higher, generally 50— mcg, in supplements containing vitamin B12 with other B-complex vitamins and even higher, typically —1, mcg, in supplements containing only vitamin B The most common form of vitamin B12 in dietary supplements is cyanocobalamin [ 1 , 3 , 23 , 24 ]. Other forms of vitamin B12 in supplements are adenosylcobalamin, methylcobalamin, and hydroxycobalamin [ 23 ]. No evidence indicates that absorption rates of vitamin B12 in supplements vary by form of the vitamin. In addition to oral dietary supplements, vitamin B12 is available in sublingual preparations as tablets or lozenges [ 23 ]. Evidence suggests no difference in efficacy between oral and sublingual forms [ 26 , 27 ]. Vitamin B12, in the forms of cyanocobalamin and hydroxycobalamin, can be administered parenterally as a prescription medication, usually by intramuscular injection [ 2 ]. Parenteral administration is typically used to treat vitamin B12 deficiency caused by pernicious anemia as well as other conditions e. Vitamin B12 is also available as a prescription nasal gel spray. This formulation appears to be effective in raising vitamin B12 blood levels in adults and children [ 28 , 29 ]. Most people in the United States consume adequate amounts of vitamin B Average daily intakes of vitamin B12 from food are 5. For children age 2—19, mean daily intakes of vitamin B12 from food range from 3. According to an analysis of NHANES data from to , people of low socioeconomic status, women, and non-Hispanic Blacks are most likely to have low vitamin B12 intakes [ 33 ]. In addition, serum vitamin B12 levels tend to drop, sometimes to subnormal levels, during pregnancy, but they usually return to normal after delivery [ 35 ]. Mean vitamin B12 intakes among supplement users from both foods and supplements were Causes of vitamin B12 deficiency include difficulty absorbing vitamin B12 from food, lack of intrinsic factor e. Because people who have difficulty absorbing vitamin B12 from food absorb free vitamin B12 normally, their vitamin B12 deficiency tends to be less severe than that of individuals with pernicious anemia, who cannot absorb either food-bound or free vitamin B Certain congenital conditions, such as hereditary intrinsic factor defects and congenital vitamin B12 malabsorption Imerslund-Gräsbeck disease , can also cause severe vitamin B12 deficiency [ 5 ]. The effects of vitamin B12 deficiency can include the hallmark megaloblastic anemia characterized by large, abnormally nucleated red blood cells as well as low counts of white and red blood cells, platelets, or a combination; glossitis of the tongue; fatigue; palpitations; pale skin; dementia; weight loss; and infertility [ 2 , 5 , 7 ]. Neurological changes, such as numbness and tingling in the hands and feet, can also occur [ 7 ]. These neurological symptoms can occur without anemia, so early diagnosis and intervention is important to avoid irreversible damage [ 36 ]. In addition, some studies have found associations between vitamin B12 deficiency or low vitamin B12 intakes and depression [ ]. In pregnant and breastfeeding women, vitamin B12 deficiency might cause neural tube defects, developmental delays, failure to thrive, and anemia in offspring [ 7 ]. Because the body stores about 1 to 5 mg vitamin B12 or about 1, to 2, times as much as the amount typically consumed in a day , the symptoms of vitamin B12 deficiency can take several years to appear [ 7 , 34 ]. Vitamin B12 deficiency with the classic hematologic and neurologic signs and symptoms is uncommon [ 11 ]. The prevalence of vitamin B12 deficiency varies by cutoff level and biomarker used. Typically, vitamin B12 deficiency is treated with vitamin B12 injections because this method bypasses any barriers to absorption. However, high doses of oral vitamin B12 might also be effective. It's very hard to get the vitamin D you need from your diet; oily fish and fortified dairy products are the only important sources. So supplements do make good sense for most adults. The form known as vitamin D 3 is usually recommended, but D 2 is also effective; for best results, take your vitamin D along with a meal that has some fat. If you want to be sure you need this supplement, ask for a blood test; levels of at least 30 nanograms per milliliter are considered best. Vitamin E, vitamin A, beta carotene, and vitamin C were the favorites of the s and early '90s. But many careful randomized clinical trials have not shown any benefit against heart disease, cancer, or other illnesses. And that's not the worst of it. In fact, even moderately high doses of vitamin A increase the risk of hip fractures, and high levels of vitamin A have been linked to an increased risk of prostate cancer; beta carotene increases lung cancer risk in smokers; and vitamin E increases the risk of prostate cancer and has been linked to an increase in respiratory infections, heart failure, and the overall death rate. Do not take antioxidant supplements. One exception: people with moderate or advanced age-related macular degeneration AMD benefit from special antioxidant supplements that also contain zinc. Unfortunately, though, this preparation does nothing to prevent AMD in people who have healthy eyes. Vitamin B 12 is found only in animal-based foods, so strict vegetarians may need supplements. In addition, many older people don't make enough of the stomach acid that's needed to liberate B 12 from animal products so it can be absorbed. But B 12 is also added to fortified grain products and other foods, and this synthetic B 12 is easy to absorb even without stomach acid. That means a single bowl of cereal can provide your RDA of 2. Still, if your fortified grain consumption is erratic, a B 12 supplement is reasonable. Folate is more complex. The vitamin is essential for the production of red blood cells, and it has an important role in DNA production and in repairing defects in the genetic code. Although folate is present in a variety of leafy green vegetables, fruits, legumes, and meats, until the late s, many Americans didn't get their RDA of mcg from foods — and folate deficiencies during pregnancy sharply increase the risk of devastating birth defects. That's why the U. and Canadian governments issued regulations mandating folic acid fortification of all grain products including cereal, bread, flour, pasta, and rice from onward.
