Folate is a water-soluble B vitamin that occurs naturally in food. Folic acid is the synthetic type of folate discovered in supplements and added to fortified food. Folic acid is accountable for lots of crucial functions throughout the body. Everybody requires folic acid, particularly pregnant women.

For that reason, it is important to obtain the correct amount of folic acid in your diet and through supplements to avoid a shortage. Nevertheless, taking excessive folic acid can result in negative signs and symptoms.

Symptoms of Having Too Much Folic Acid in Your Body

Symptoms Folic Acid Overdose

Having excessive folic acid in the body can result in a range of signs and symptoms. Less serious side effects include digestive problems, queasiness, anorexia nervosa, bloating, gas, a bitter or undesirable taste in the mouth, sleep disruptions, depression, excessive enjoyment, irritation and a zinc shortage.

In the USA many grain products are fortified with folic acid.

More severe signs include psychotic behavior, numbness or tingling, mouth pain, weakness, problem concentrating, confusion, fatigue as well as seizures. An allergic reaction to folic acid may cause wheezing, swelling of the face and throat or a skin rash.


Folic acid is vital in the production of DNA and RNA, the foundation of all cells. Folic acid is required for normal red cell production, the metabolism of homocysteine, the maintenance of amino acid levels and preventing changes to DNA that might lead to cancer. Maybe the most crucial function of folic acid is the avoidance of insufficient development of the spine and brain in babies when taken by pregnant women. Folic acid is likewise used to treat deficiencies and anemia caused by an absence of folate in the body.

Advised Dietary Allowance

The Food and Nutrition Board of the Institute of Medicine has actually established recommended dietary allowances for folate. Babies from birth to 6 months of age require 65 mcg daily and infants from 6 to 12 months need 85 mcg daily. Children 1 to 3 years of ages need 150 mcg day-to-day and children 4 to 8 years of ages requirement 200 mcg each day.

Form the age of 9 to 13, children need 300 mcg of folate everyday. Teenagers through the adult years require 400 mcg daily. Pregnant women require 600 mcg each day and breastfeeding women need 500 mcg every day. Folic acid needs increase when individuals are under physiological stress, have a high metabolic process or struggle with conditions such as hypothyroidism.

Green leafy veggies, citrus fruits and juices, beans, eggs, fish and organ meats are rich sources of folate. Folic acid is contributed to strengthened breakfast cereals, bread products and orange juice. Folic acid fortification significantly helps people fulfill their advised everyday allowances. In many cases, however, supplemental folic acid is advised. It is offered as a single component vitamin or in mix products such as in multivitamins and B complex vitamins. A dose of 1 mg or greater needs a prescription.


There is no health risk related to folate consumption from food. However, there is risk of toxicity from folic acid found in dietary supplements and fortified foods. Folic acid is used to treat a folate deficiency. Nevertheless, a folate deficiency is virtually identical from a vitamin B12 deficiency. Large dosages of folic acid provided to a person who has a vitamin B12 shortage and not a folate deficiency can cause permanent neurological damages.

The Food and Nutrition Board of the Institute of Medicine has actually developed a bearable upper intake level for folate. For children 1 to 3 years the limit is 300 mcg daily, for children 4 to 8 the limitation is 400 mcg daily, for children 9 to 13, the limit is 600 mcg daily, for teenagers 14 to 18 the limit is 600 mcg and for those 19 and older the limit is 1,000 mcg per day. Intakes above recommended limits increase the risk of adverse health impacts.

Too Much Folic Acid During Pregnancy

Certainly, you ought to consult your own doctor, however the recommendation for all women of childbearing age is 400 mcg and the suggestion for pregnant women is 800 mcgs to prevent neural tube abnormality. For women with a family history of neural tube flaws, the suggestion increases to 4000 mcg.

So I believe you’re fine. It’s really hard to get excessive folic acid – your body excretes any excess. Unless you have some extremely rare health condition for which it is contraindicated (e.g., a vitamin B deficiency that will be masked by supplementation), I wouldn’t fret about it. Always remember that the neural tube closes really early, so you have to be taking folic acid as soon as you know you’re pregnant (even much better if you start before you develop).

Medical news

Pregnant women are motivated to obtain plenty of folic acid in their diet or through vitamin supplements, to protect their infants against abnormality of the brain and spine.

However a brand-new study recommends that extreme amounts of folate (vitamin B9) and vitamin B12 in a mom’s body might increase a baby’s risk of establishing an autism spectrum disorder.

” The brand-new research concern before us is to comprehend the ideal dose,” said co-researcher Daniele Fallin. She is a professor at the Johns Hopkins Bloomberg School of Public Health in Baltimore.

” Some [folate] is an advantage. It does appear the levels in the body might get too expensive, which would be a bad thing,” she stated.

” Supplementation is certainly an essential thing,” Fallin included. “We would not desire anybody to interpret from this that they must stop taking vitamin supplements if they are planning to get pregnant or if they are pregnant.”

In the study, mothers who had really high blood levels of folate at delivery were two times as likely to have a child with autism compared with mothers with typical folate levels.

Scientists also found that mothers with extreme B12 levels were 3 times as likely to have a child with autism.

The risk was biggest amongst moms who had excess levels of both folate and B12– their risk was over 17 times that of a mom with typical levels of both nutrients, the private investigators reported. Nevertheless, the research study only found an association and could not prove that high levels caused an increased risk of autism.

Folate is discovered naturally in fruits and vegetables, while the artificial variation, folic acid, is used to fortify cereals and breads in the United States, and in vitamin supplements.

However, expecting mothers should not toss away their supplements, the researchers worried.

The study likewise discovered that women who took folate and B12 supplements three to 5 times a week were less likely overall to have a child with autism, especially when they’re taken during the first and second trimesters, Fallin stated.

The March of Dimes, the American College of Obstetricians and Gynecologists and other medical associations suggest that pregnant women take in folic acid to prevent neural tube flaws, which occur in about 3,000 pregnancies each year in the United States. Spina bifida is the most typical of this type of birth defect.

And current research studies have likewise suggested that folate and vitamin B12 might secure an establishing fetus against future autism, Fallin stated.

To investigate this result, Fallin and her coworkers examined data from nearly 1,400 mother-child pairs in the Boston Birth Cohort, a mainly low-income minority population.

The moms were recruited at the time of their children’s birth between 1998 and 2013, and followed for several years. The study consisted of a check of the moms’ blood folate levels within 3 days of delivery.

The scientists discovered that one in 10 of the women had what is considered an excess quantity of folate, while 6 percent had an excess amount of vitamin B12.

” We saw those women who had extremely high, much greater than the recommended amount, of folate or vitamin B12 were most likely to have children who later had a diagnosis of autism,” Fallin said.

Fallin and her colleagues could not state from their information why particular women had excessive levels of folate or B12 in their systems around the time of delivery, although many stated they took vitamin supplements during their pregnancy.

It might be that some women are genetically predisposed to high levels of folate and B12 in their bodies, or they may be getting excessive of the nutrient through diet or supplements, she stated.

Women need to talk with their obstetrician about their diet and supplements, and how those may be affecting their blood levels of folate and B12, Fallin said.

Dr. Paul Wang, senior vice president of medical research for Autism Speaks, concurred that “it’s just too early to state” what this study means, particularly since it hasn’t yet appeared in a peer-reviewed medical journal.

” We have to see the full research study,” Wang stated. “We have to look at all the information they have.”

Wang kept in mind that the study does show a protective advantage against autism for folic acid and vitamin B12 in women taking supplements 3 to 5 times a week.

” What we’ve always thought to be true remains true, that supplements decrease the risk of autism,” Wang said. “The bottom line still is that taking the suggested vitamins is overall decreasing your child’s risk.”
