L-Lysine (or Lysine) is used to treat herpes simplex and can cause mild side effects in a patient. It is tested to see whether it can help in fighting osteoporosis. Lysine is an essential amino acid and as such cannot be synthesized in the human body, but instead, it has to be taken from another source.
Side effects of L-Lysine
Food sources that contain lysine are red meat, eggs, beans, soya, peas, spinach, cheese and fish (usually sardines and cod). L-Lysine is necessary for the body because it is crucial for protein production for muscles, in calcium absorption, and it is essential for the production of enzymes, hormones and antibodies.
Herpes simplex is responsible for both cold sores and genital herpes. Although tests have been conducted around the world, there are still not enough reliable evidence that shows that lysine intake is responsible for improving condition in patients who are suffering from herpes. It is considered as “possibly effective” in treating herpes.
However, the side effects of lysine intake are documented. Lysine is not toxic to humans, but an overdose can cause an increase in triglyceride and cholesterol levels. People that are prone to cardiovascular disease will have first to consult their doctor. Doses of lysine that exceed 10 g per day can cause vomiting, nausea, stomach cramps and diarrhea. Prolonged excessive intake can lead to a gallstone.
Benefits of lysine. It is recommended for patients with osteoporosis to take lysine as it helps the body to absorb calcium and make better bones. When taken with vitamin C, it appears to diminish symptoms of angina pectoris. In equal amount with another essential amino acid, arginine, it helps build muscle tissue. There are some types of lysine conjugates which help in cancer prevention. The recommended dosage of lysine is 500 mg. To maximize the effect of lysine, you can take up to 1 g of lysine without adverse effects.
