What It Is

Cooper Complete®  L-Lysine Plus Vitamin C Supplement contains 1000 mg lysine and 2000 mg vitamin C to support connective tissue, skin and collagen health.

How to Use:

As a dietary supplement, take four (4) vegetarian capsules or as directed by your health care professional. Each bottle contains 30 servings.

How It Helps

L-Lysine Plus Vitamin C supplement combines 1000 mg l-lysine with 2000 mg vitamin C. L-lysine is an essential amino acid, which must be obtained through protein-rich foods or supplementation. 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.†

Immune Health

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

Wound Healing

Lysine and vitamin C support the healing of sores and wounds because of their benefits to collagen formation and immune function.†

Skin Health

Lysine and vitamin C promote collagen formation and are essential for building and repairing connective tissues and skin elasticity.

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 Energy Production

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.

As a dietary supplement, adults take four (4) vegetarian capsules daily or as directed by their health care professional.
