How many courses of treatment should lysine be taken per year

The duration of taking lysine should be determined based on individual health status and doctor's advice, usually not exceeding 3 courses per year. Lysine is one of the essential amino acids in the human body, mainly used to improve immune function, promote calcium absorption, and assist in the treatment of herpes simplex virus infection. Healthy individuals do not require long-term supplementation, and specific groups should take according to their needs under the guidance of a doctor. When lysine is used as a nutritional supplement, short-term use can help improve malnutrition or postoperative recovery. Children in their growth and development period, vegetarians, or those with insufficient protein intake can supplement their diet after evaluation by a doctor. Each course of treatment lasts about 1-2 months, and the interval between courses should be combined with dietary assessment. Excessive supplementation may cause gastrointestinal discomfort or burden on liver and kidney metabolism. It should be stopped immediately when symptoms such as nausea and abdominal pain occur. When used as an adjuvant therapy for herpes virus infection, antiviral drugs should be used in combination, and the course of treatment is usually 2-4 weeks. Individuals with low immune function may require periodic repeated medication, but the cumulative duration of medication throughout the year should not exceed 3 months. Long term high-dose use may interfere with arginine metabolism and affect vascular function, making cardiovascular disease patients particularly cautious.

Foods rich in lysine in daily diet include fish, lean meat, soy products, and dairy products, and a balanced diet can usually meet the needs. During the use of lysine preparations, it is advisable to avoid consuming high arginine foods such as nuts and chocolate simultaneously. It is recommended to regularly monitor liver and kidney function. If there are allergic reactions or persistent dizziness, it is necessary to seek medical attention and adjust the plan in a timely manner.
