Introduction To L-Lysine


Unleash Your Power To Build*

Lysine is an essential amino acid. This means that the human body cannot produce Lysine and this important amino acid must be obtained from dietary intake. Lysine works with other essential amino acids to maintain growth, lean body mass, and the body's store of nitrogen.*

Where does Lysine come from? Chicken, beef, some fish, soy, eggs, brewer's yeast, legumes/beans, and dairy all contain significant amounts of lysine. Most people consume enough lysine to stay healthy. For vegetarians and vegans, it's important to combine foods like beans and rice/tortilla, pita and falafel, or hummus and bread to get a complete amino acid profile in their daily diets.

Build A Strong Foundation*

Lysine has been attracting attention as a possible addition to the fast-growing list of muscle-building nutrients.* Lysine is a necessary building block for all protein in the body. Lysine plays a major role in calcium absorption, building muscle protein, and the body's production of hormones, enzymes, and antibodies.*

Lysine appears to help the body absorb and conserve calcium.* Lysine has many functions in the body because it is incorporated into many proteins, which are used by the body for a variety of purposes.

Vigorous Exercise Requires Detailed Dosing

Lysine supplements are safe for men and women of all ages. If you're an athlete or you exercise vigorously 3-5 times a week you may benefit from extra Lysine supplementation. Athletes and others involved in frequent vigorous exercise have an increased need for essential amino acids.

Lysine is sold in capsule, tablet, and powder form, and the regular serving size is between 400-500mg 1-3 times a day. Read the label instructions on each product you buy and follow them carefully.
