What is Folic Acid?

Folic acid is a form of vitamin B and is water-soluble. It has been found as an additive in many foods for the past 15 years as a result of FDA regulations being changed. Some of the many foods that now include folic acid as a result of this are pastries, cold cereals, breads, flour, and pasta. There are also many foods that are naturally rich in folic acid, including green vegetables (broccoli, lettuce, etc.), fruits (melons, lemons, bananas, etc.), meats (kidney, beef liver, etc.), juices (orange, tomato), beans, and yeast.

How does it work?

To properly and naturally develop the human body, it is necessary for it to always have sufficient levels of folic acid. It assists with DNA production and plays a role in various other functions within the human body.

Used To Treat

Folic acid is primarily used for treatment purposes to remedy a deficiency of folic acid. It can also effectively treat the relevant symptoms, such as anemia and improper nutrient absorption in the bowels. It is also sometimes used to treat other medical issues that are correlated with a deficiency of folic acid, such as alcoholism, liver disease, kidney dialysis, and ulcerative colitis.

Any woman that is currently pregnant or intended to become pregnant will need sufficient levels of folic acid, or else they are at increased risk of a miscarriage and spina bifida, as well as other birth defects.

Certain folic acid supplement users will use the supplement to lower the risk of developing cervical and colon cancer, stroke, heart disease, and heart disease.

Further, folic acid may be used to treat a loss of memory, loss of hearing from aging, and Alzheimer’s disease. It may also lessen the severity of symptoms noticed by individuals that are suffering from osteoporosis, age-related macular degeneration (AMD0, fragile-X syndrome, vitiligo, AIDS, and restless leg syndrome. It may also help to treat muscle and nerve pain, sleeping complications, and mild to severe cases of depression.

Individuals suffering from an infection of the gums may use a topical application of folic acid to their gums.

Typically, folic acid will be taken along with other types of B vitamins.

Key benefits

Folic acid supplements are considered as safe for everyone, including women that are pregnant and nursing, as long as the recommended dosing amounts are followed.

Goes well with

Folic acid is best combined with a healthy diet and general well-being.

How to take/dosage


-          To treat a deficiency of folic acid, it is best to take between 250 and 1,000 mcg each day.

-          To lower the risk of birth defects, a minimum of 400mcg each day through either supplement or dietary intake is advised for women that may get pregnant. This dosing should continue until the second month of pregnancy. If you have had pregnancy complications in the past, then 4mg each day a month prior to getting pregnant and until the end of the first trimester is suggested.

-          To lower the chance of developing colon cancer, 400mcg each day is recommended.

-          To reduce homocysteine blood levels, the following has been tested:

1)      0.5 to 5 mg per day, but 0.8 to 1 mg has appeared to provide the best results.

2)      For those at the end of renal disease, and looking to treat homocysteine levels, a wider range may be necessary. 0.8 to 15 mg each day is recommended. Alternatively, dosing three times per week at 2.5 to 5 mg per dose may be done. Anything in excess of 15mg in a single day has not been found to provide additional benefits.

-          To enhance anti-depressant response, 200 to 500 mcg each day has been tested.

-          To treat vitiligo, 5mg should be taken twice per day.

-          To lower toxicity from methotrexate therapy, which is commonly used to treat patients with rheumatoid arthritis (RA) and patients with psoriasis, a total of 1mg each day is usually sufficient. Patients may take upwards of 5mgs per day.

-          To decrease the risk of macular degeneration, a mixture of 2.5mg of folic acid, 50mg of vitamin B6, and 1,000mcg of vitamin B12 has been used.


Sufficient folic acid intake in babies that are no more than six months of age is 65mcg in a single day. This increases to 80mcg in a single day for babies that are up to a year old. In consideration of the recommended dietary allowances (RDAs) set for both folate from food and folic acid from supplements and fortified foods is as follows:

-          150mcg per day for children one to three years of age

-          200mcg per day for children four to eight years of age

-          300mcg per day for children nine to 13 years of age

-          400mcg per day for anyone over 13 years of age

-          600mcg per day for women that are pregnant

-          500mcg per day for women that are breastfeeding

Tolerable folic acid intake is practically double in all areas. The tolerable intake levels by age are as follows:

-          300mcg per day for children one to three years of age

-          400mcg per day for children four to eight years of age

-          600mcg per day for children nine to 13 years of age

-          800mcg per day for young adults, 14 to 18 years of age

-          1,000mcg per day for anyone that is 18 years of age or older

Possible side effects

Folic acid is considered to be most likely safe to use for the majority of individuals. While sticking to the RDA of 400mg per day, there are very few cases of side effects in adults.

In higher amounts, folic acid may trigger these, and many other side effects: feeling irritated, nauseous, confused, experiencing stomach cramps, changes to your behaviour, diarrhea, flatulence, series, and having difficulty sleeping or developing sleep disorders.

While there is not conclusive evidence, there are worries that excessive folic acid intake for an extensive amount of time could result in more severe side effects. Certain findings indicate that folic acid intake in the amounts of 800 to 1,200 mcg per day could also cause a greater chance of experiencing a heart attack for those that already have heart-related health issues. Other findings also indicate that folic acid intake in excessive amounts could cause an increased chance of developing various types of cancer, including cancer of the prostate and lungs.

It is advised to restrict your intake of folic acid to no more than 400mcg in a single day unless authorized otherwise by your doctor or pharmacist.


-          Seizure Medication: medication that is used for patients that experience seizures, such as fosphenytoin (Cerebyx), may have a bad interaction with folic acid supplements. The body destroys this medication and gets it out of its system, but excessive folic acid may speed up the deterioration process. If this occurs, then the seizure medication may not be as effective or long-lasting as it would if the folic acid did not interfere.

-          Methotrexate (MTX): as this operates by diminishing the effectiveness of folic acid on cells in the human body, the combination of the two will negate the intended effects of methotrexate medications.

-          Phenobarbital (Luminal): as another type of seizure medication, it is possible that folic acid supplementation may decrease its effectiveness in lowering the risk of seizures.

-          Phenytoin (Dilantin): as this medication is broken down within the body for removal purposes, and folic acid can speed up the breakdown process, it is possible that the effectiveness of this medication will be hindered as a result of using both of these. This may result in an increased risk of seizures.

-          Primidone (Mysoline): the issue is very much of the same as this is another form of seizure medication and due to the processing of the two; it is possible that the preventative effects may be decreased when using these two together.

-          Pyrimethamine (Daraprim): this medication is used for the purpose of treating infections caused by parasites. It is possible that this medication will not be as effective as a result of high levels of folic acid.

Safety concerns

There are no safety concerns if you constantly stay within the recommended dosing amounts. However, anyone that is epileptic or suffers from frequent seizures should speak with their doctor prior to using folic acid as it may hinder the effectiveness of most anti-convulsant medications.

Things to note

It is especially important for women that are pregnant to use the recommended dosage and remain consistent with the supplement use.
