Adults, as a dietary supplement, take one (1) capsule three times daily, preferably one hour before a meal with an adequate supply of water to aid in absorption.

An essential building block for protein and the formation of collagen, which provides structure to your bones, muscles and skin, lysine can’t be produced in your body on its own – you must get it from dietary sources or supplements.

Many individuals don’t get enough lysine through food sources, so supplementation may be advisable for when you want extra support for your body’s natural defenses.*

Lysine and arginine work together in your body, and their ratio influences your immune system. By increasing lysine by taking L-Lysine, you offset and inhibit the absorption of arginine, thus providing your body with extra immune support.*

Most people get more arginine from their diet than they do lysine. So, an arginine-restricted diet – and avoiding coffee or caffeine – may be advisable during occasional times to provide optimal support to your immune system against threats. Some individuals like to increase their intake of L-Lysine to 2,000 to 3,000 mg per day during these more challenging times.*

For everyday use, an arginine-restricted diet isn’t necessary when taking L-Lysine, as simply supplementing with L-Lysine provides your body with the extra immune support it may need for routine care.*
