Lysine Side Effects

Lysine is an essential amino acid found in food and supplements that is important for body growth. It is crucial for helping the body to produce energy, lower its cholesterol levels, aid to collagen formation for the skin, cartilage and tendons. As it cannot be produced in the body, it should be obtained from the daily diet. Its deficiency in the body causes loss of appetite, fatigue, slow growth, anemia, nausea, fatigues, bloodshot eyes and reproductive disorders. It is available in form of food supplements, which are prescribed by a medical practitioner.

An excessive intake of lysine causes allergic reactions. Although the allergies differ from person to person, patients will often experience swellings around the face, lips and tongue. It also causes blocking of the throat, and difficulties in breathing.

2. Interaction with Antibiotics

Lysine is not to be mixed with other drugs unless recommended by a doctor. Antibiotics such as gentamicin, tobracin, netilmicin, neomycin, amikacin, kanamycin, streptomycin and tobramycin react with lysine causing adverse effects. These can cause body toxins and can be lethal. It is important to take the supplements under strict medical guidance.

3. Causing Health Disorders

Lysine is responsible for hardening of arteries; it also causes stomach cramps, diarrhea and gall stones. Anyone with any medical conditions needs to seek medical advice before using lysine. It is forbidden for people with heart, kidney, and liver conditions. Expectant women and nursing mothers are also cautioned against taking lysine since its negative effects are unclear.

4. Heavy Metals

These amino acids have been found to contain heavy metals, which are harmful to your health. These can cause death as a result of poisoning. Since there is no regulatory standard against the manufacture of lysine, caution should be taken when using it. In case of an overdose, immediate medical treatment should be sought.

Lysine Dosage and Cautions

Lysine supplements are often used in treatment of lysine deficiency and other medical conditions. It should be prescribed by a doctor because self diagnosis is risky and could lead to over use of the supplement. Since most people obtain lysine form their usual diet, it is not necessary to take the supplement. However, it may be prescribed for health conditions and lysine deficiency symptoms. The medically diagnosed conditions can warrant the consumption of lysine supplements. These could be in the form of tablets, syrups, capsules or creams.

The prescription is often done in different doses and, therefore, should not be taken as a single dose. A medical practitioner will accurately diagnose the deficiency level of Lysine to prescribe the right amounts. There are proper doses for adults, children and people with medical conditions.

  • The most common prescription requires that 12 mg of lysine is taken for every kilogram in weight of the patient.
  • When used as a supplement treatment for cold sores and herpes, the dose should be between 500 mg to 1500 daily.
  • In this case, it is restricted for children below 2 years, but those over 2 years can use 23 mg per kg.

When taken as a dietary supplement, it is important to use it under medical supervision. This is because caution is needed when taking other drugs since lysine tends to react with antibiotics and other drugs. Excess supplements in a diet mixed with other drugs could be dangerous. A toxic intake of Lysine and arginine mixed together causes infertility in men. In common cases, an overdose of 10g of lysine could cause bloody diarrhea, diarrhea, and stomach cramps among others.
