Role of Supplements in Epilepsy


In people with epilepsy, there is increased nutritional risk because of altered nutrient needs, drug-nutrient interactions, and sometimes nutritional deficiency due to seizures, metabolic disorders or diarrhea (side effect of AED used). 

Nutrient needs may be altered as a result of the long-term medication therapy use in epilepsy. Disorders of vitamin D, calcium, and bone metabolism result when the anticonvulsants phenytoin and/or phenobarbital are used for an extended period of time.

Metabolic disease that results in an inability to properly utilize a particular nutrient in the body, such as a vitamin or an amino acid can sometime give rise to seizure. About 20 to 80 different metabolic disorders that are most commonly associated with seizures. Seizures associated with metabolic disorders usually begin soon after birth and rarely start after age six.

Seizures can also be caused by nutritional deficiency. Research suggests that shortages of magnesium, thiamin, vitamin B6 and zinc have been reported to be associated with seizures in some individuals while a manganese deficiency in pregnant women may result in the birth of epileptic children. These nutrients, among numerous others, are needed for normal chemical reactions in the brain. 

Nutritional support for people with seizure disorders, then, involves correcting metabolic problems and nutritional deficiencies. In some cases, it may also involve taking larger amounts of certain nutrients to help protect against drug-related damage and possibly against damage caused by the seizures themselves. 

A number of nutrients have proven useful in helping to prevent seizures. Many doctors recommend a multivitamin/mineral supplement for their patients with epilepsy. However, most cases of epilepsy are not treated with supplements although it proves to be successful for some. 

IMPORTANT: DO note that these supplements are meant to provide optimum nutritional support, not to be treatments in and of themselves. It is important to work with a doctor knowledgeable in nutrition, especially if you are giving nutritional supplements to children.

Vitamin E

It is believe that vitamin E could be helpful for some kinds of seizures. In children, whose seizures initially could not be controlled by medication, seizure frequency was found to decrease in 60-100% of the children when they took 400 international units of d-alpha-tocopherol acetate per day for three months in addition to their regular medication. Animals given vitamin E are more resistant to seizures induced by pressurized oxygen, iron and certain chemicals. And clinical studies show that people taking anti-epileptic drugs have reduced blood levels of vitamin E. 

Vitamin E apparently has no direct anti-epileptic action but act as a scavenger and take up free radicals protecting the membranes of brain cells in some forms of epilepsy such as post-traumatic seizures. In animals, seizures can be induced by chemicals (e.g. ferrous chloride) that produce free radicals. 

It is safe and effective even in children as young as age three. Nutrition experts say that infants under age one should not be given more than 50 international units daily. Most adults can safely take up to 600 international units without problems. It is important not to take more than this amount daily without medical supervision. No adverse side effects was associated and if vitamin E is effective the benefits will be apparent in about three months. In some cases, under medical supervision, it may be possible to reduce the dosages of some seizure drugs.



The mineral selenium is another nutrient, which act as scavenger for free radicals, having antioxidant properties and also appears to help control seizures in some children. It was found that some children with severe, uncontrollable seizures and repeated infections have low blood levels of glutathione peroxidase, a selenium-dependent antioxidant enzyme. 

Giving 50 to 150 micrograms of selenium a day to children significantly reduces their seizures. Metabolic problem that prevents usage of selenium properly may be the reason behind it. Children's needs can vary greatly depending on the amount of deficiency they have, and giving too much selenium could be detrimental to their health.

For adults with epilepsy, experts who use nutritional therapy recommend 50 to 200 micrograms of selenium daily to control seizures. A dosage of more than 100 micrograms daily of selenium requires medical supervision. However, It is possible that one can get more selenium from foods if lots of garlic, onions, whole grains, mushrooms, broccoli, cabbage and fish are included in meals.


Folic Acid

Deficiency of folate (the naturally occurring form of folic acid and a form of vitamin B complex ) can be caused by some anti-epileptic drugs sometimes leading to abnormalities in red blood cell formation. Folate deficiency can also lead to serious birth defects called neural tube defects  which happen very early in the pregnancy, often before a woman knows she is pregnant.

It is therefore advisable any woman of childbearing age who is taking anti-epileptic drugs should also take 1,600 micrograms of folic acid a day. And any woman taking anti-epileptic drugs and planning to become pregnant should take three milligrams (3,000 micrograms) of folic acid every day for three months before she stops using birth control. Such high amount of folic acid requires a prescription supplement. A few doctors recommend up to 5,000 micrograms a day for adults. Others taking anti-epileptic drugs should take 400 micrograms which is the amount of folic acid found in ordinary multivitamin/mineral supplements. Some experts say that children ages 5 to 15 may safely take up to 2,500 micrograms daily under doctor's recommendation. 

Make sure that you are under a doctor's supervision when taking more than 400 micrograms, because high amounts of folic acid can mask the symptoms of vitamin B12 deficiency such as pernicious anemia.
