L-Lysine

The human body needs lysine for healthy functioning. It is an essential component of proteins that plays a role in helping body tissue develop and recover from injury. Other benefits of lysine include:

• helping the body absorb calcium, iron and zinc
• promoting collagen growth
• contributing to the production of enzymes, antibodies and hormones
• supporting the immune system

When people do not get enough lysine, they may experience the following symptoms:

• fatigue
• difficulty concentrating
• irritability
• nausea
• red eyes
• hair loss
• anorexia
• growth inhibition
• anaemia
• reproductive system problems

Lysine may help control the herpes virus. As a result, lysine supplements may reduce the number and frequency of cold sore outbreaks caused by the herpes simplex virus type 1.

Lysine may also help treat genital herpes. Some sources recommend that people with a history of herpes infections take 1,000 to 3,000 milligrams (mg) of lysine supplements per day.

Due to the functions that lysine supports in the body, researchers are interested in the potential of lysine supplements for:

• preventing lean muscle loss and mobility problems in older adults
• relieving anxiety
• preventing bone loss and osteoporosis helping the body absorb calcium
• promoting healthy skin growth
• treating shingles
• moderating blood pressure
• preventing plaque formation in the arteries
• supporting hair growth
• building muscle in bodybuilders
• helping athletes recover from intense workouts

Experts believe that lysine is most effective when people take it with water on an empty stomach.

Researchers estimate that a 70-kilogram (kg) person needs approximately 800-3,000 mg of lysine per day. A person's body weight affects how much they need, as follows:

• 12 mg/kg body weight for adults

44 mg/kg for children aged 11 to 12 years

97 mg/kg for infants aged 3 to 6 months

People recovering from burns or other serious injuries and people who engage in frequent, high-intensity training may benefit from a higher than average daily intake of lysine.

People who use this amino acid to enhance their fitness training may get greater benefits if they take it before bed or before exercise.

L-Lysine supplementation is contraindicated in people with a rare genetic disorder called hyperlysinemia.

Taking lysine supplements is very safe and does not appear to cause many side effects. Most people can take a daily dose of up to 3 grams (g) of lysine without side effects.

Increasing the dose of lysine to 10-15 g per day may lead to digestive problems such as:

• diarrhoea
• nausea
• stomach cramps

There are reports of an association between lysine supplements and kidney problems, and animal studies suggest that lysine supplements may increase the risk of gallstones and high cholesterol.
