Lysine is a type of amino acid, a component of protein that the body needs to get from the diet. Lysine serves several important functions including cartilage formation and helping the body absorb calcium. It can be found in foods that contain protein, such as red meat, poultry, cheese, eggs and soybeans and most people get enough lysine through their diets. Lysine is also an important component of carnitine, a nutrient that may have an effect on autism.
Autism
Autism is a disorder that affects a person's ability to communicate with others. Autism can manifest as behavioral issues, including frequent tantrums; repetitive, self-stimulating behaviors; and food intolerances. It has no exact cause, although environmental factors may play a role. There is no specific treatment for autism, although many parents and professionals have found success in treating symptoms with some types of dietary restrictions or supplements, such as amino acids.
Carnitine
Some people have used carnitine as a supplement for help with symptoms of autism. According to the Natural Health Research Institute, autism may be affected by mitochondria, the cell components that are responsible for energy. Carnitine works to use fatty acids for energy and may support the work of the cell mitochondria. It is created from two different amino acids, lysine and methionine. If autism is related to malfunctioning mitochondria, then supplementing with carnitine may help reduce some symptoms of the disorder.
Protein Intake
When you eat foods that contain protein, they are broken down into amino acids, such as lysine, during the digestive process. Some people with autism may have difficulty digesting protein due to gastrointestinal problems or they may not get enough protein through their diets. To increase protein intake to gain the benefits of amino acids, you may consider eating two 4-oz. servings of protein each day. Additionally, some digestive enzymes are available as supplements that work in the gastrointestinal tract to help the body break down protein into amino acids for absorption.
Considerations
Lysine and carnitine are available as supplements without a prescription. Before taking these types of supplements, talk with your doctor about their use as a method of treating autism. Your doctor can advise you about dietary recommendations as well as any interactions these supplements may have with other medications. Although some families have had success with helping symptoms of autism by using dietary supplements, lysine is not necessarily a cure for this condition.
