What It Is

Cooper Complete®  L-Lysine Supplement contains 1500 mg (1.5 grams) of l-lysine (and is non-hydrolyzed, naturally produced, free-form L-Amino Acid) to support connective tissue, skin and collagen health.

How to Use:

As a dietary supplement, take one (1) capsule three (3) times daily or as directed by your health care professional. Each bottle contains 100 capsules.

How It Helps

L-Lysine Supplement contains 1,500 mg (1.5 grams) of the essential amino acid L-Lysine. L-lysine is an essential amino acid, which must be obtained through protein-rich foods or supplements as it cannot be manufactured by the body. A building block of protein, lysine is used by the body to produce collagen, and it aids the body in calcium absorption. Meat, fish, poultry, dairy, tofu, lentils, and beans are the primary dietary sources of lysine. L-Lysine refers to the biologically active form of lysine in supplement form.

Bone Health

Lysine supports calcium absorption, which is needed for strong teeth and gums, bones and cartilage.†

Promotes Healthy Immune System

It helps the body maintain a healthy immune response by producing collagen, digestive enzymes, antibodies, and protein hormones.†

Wound Healing

L-Lysine Supplement supports the healing of sores and wounds because of its benefits to collagen formation and immune function.†

Supports Healthy Skin Support

Lysine is crucial to collagen formation and is essential for building and repairing connective tissues and skin elasticity of unhealthy skin. It promotes healthy gum and lip tissues.†

Herpes Simplex Virus (cold sores and genital herpes)

Almost half (48.1%) of Americans ages 14-49 have been exposed to oral herpes (herpes simplex virus type 1 (HSV-1)), while slightly more than 20 percent of American adults aged 40-49 have genital herpes (herpes simplex virus type 2 (HSV-2). Some but not all studies suggest daily supplementation (between one and three grams of lysine) may help reduce the occurrence and severity of cold sores.

Supports Healthy Metabolism

In the body, the liver and kidneys use the amino acid lysine (and methionine) to produce carnitine, which is critical in energy production. Carnitine helps convert long-chain fatty acids into energy.

Easy To Take

The formulation of Cooper Complete L-Lysine Supplement 1500 mg (1.5 grams) provides the body with non-hydrolyzed, naturally produced free-form L-Lysine amino acid in order to promote optimal absorption and assimilation into the body’s systems. In addition, this product contains NO gluten or dairy and is free of genetically modified organisms (GMOs).

As a dietary supplement, adults take one (1) capsule three (3) times daily or as directed by their health care professional.
