L-lysine is an amino acid that is part of all proteins in the human body. While it is critical to the health of the body, it is one of the amino acids that cannot be produced by your body! Instead, you must eat one of the sources of lysine each day. Fortunately, whether you eat meat or are a vegetarian, there are some good sources of lysine including spinach, soybeans, lentils, eggs, cheese, red meat, fish, pork and poultry. You can also take over-the-counter l-lysine supplements; before you do that, be sure you understand the side effects that may develop and talk to your nutritionist or healthcare provider first.
L-lysine Benefits
You may experience many health benefits when you have an adequate intake of l-lysine in your diet.
Precautions for Taking L-lysine
It is possible to have abnormal l-lysine levels - both too much and too little.
Abnormal L-lysine Level Symptoms
- L-lysine deficiency. If you do not have enough l-lysine, you may experience symptoms much like you would with the flu. You may have nausea and vomiting, excessive tiredness, and dizziness. If you are a woman who is not able to get pregnant, talk to your doctor as Infertility may be one of the side effects of an l-lysine deficiency.
- L-lysine excess. If you have too much l-lysine, you can have nausea, vomiting, Diarrhea, and abdominal cramping. You may develop gallstones or elevated triglycerides if you have a very high intake of l-lysine.
Recommended Dosage
If your healthcare provider wants you to take supplemental l-lysine, the recommended dosage will depend on why you need it. For a healthy adult without health problems, a normal dose is about 12 mg/kg/day. For an adult who weighs 150 pounds (68 kg), the recommended daily dose would be 816 mg per day. However, if you are taking the lysine for herpes treatment, that dose may be increased to 1000-3000 mg three times a day. Before taking high dose lysine, be sure to talk with your healthcare provider who should help you determine how long you should take lysine at higher doses. Those who had suffered from cardiovascular problems before must consult the doctor before taking any lysine supplements.
Precautions for Taking L-lysine
Although l-lysine occurs naturally in foods, the Food and Drug Administration has not approved the amino acid supplement for treatment of any specific diseases or illnesses. As with any supplement, there are certain groups who should consult a doctor before taking l-lysine. Women who are pregnant or breastfeeding should consult a doctor. If you are taking any other medications (including antibiotics), talk to your doctor or pharmacist to ensure that there are no interactions between medications. Because this drug is process in the liver, be sure to talk to your healthcare provider before taking supplemental doses of l-lysine.
