What Is L-Lysine?
Lysine, a building block for protein, is an essential amino acid, which means it is not produced by our bodies. Therefore, it has to be obtained through our diet. Lysine helps encourage a healthy stress response and helps inhibit glycation, which can play a role in a variety of age-related factors. L-Lysine is an indispensable amino acid that our bodies can't produce, making it essential to acquire it from food or supplements. With its role in vital processes such as protein synthesis, tissue growth and repair, collagen production, enzyme creation, hormone regulation, and calcium absorption, L-Lysine ensures the smooth functioning of our bodies.

The notable health benefits of L-Lysine supplementation, supported by scientific studies, include:

1. Cold sore prevention and treatment: By inhibiting the replication of the herpes simplex virus type 1 (HSV-1), L-Lysine can reduce both the severity and duration of cold sore outbreaks. It bolsters the immune system and reduces inflammation, contributing to its efficacy against cold sores.

2. Cardiovascular health support: L-Lysine can help decrease blood pressure by enhancing blood vessel elasticity. It also lowers homocysteine levels—an amino acid linked to blood vessel damage and cardiovascular diseases—contributing to heart health.

3. Blood sugar regulation: By augmenting insulin sensitivity, glucose uptake, and glycogen synthesis, L-Lysine helps maintain stable blood sugar levels. This property makes it beneficial for preventing or managing metabolic syndrome, diabetes, and associated cardiovascular diseases.

4. Cognitive function and mood enhancement: L-Lysine can alleviate stress, anxiety, and depression by regulating cortisol, serotonin, and dopamine levels in the body. These neurotransmitters play crucial roles in mood regulation and reward processing, influencing overall mental well-being.

5. Skin health promotion: L-Lysine shields the skin from oxidative stress, UV radiation, and microbial infections, and boosts wound healing. It's also beneficial in preventing or treating skin conditions such as acne, eczema, and psoriasis.

6. Bone health support: L-Lysine aids the body in absorbing calcium—critical for bone formation and density. By stimulating collagen production, it may also assist in preventing or treating bone loss and osteoporosis. L-Lysine provides these multi-faceted health benefits, making it a must-have addition to your health supplement regimen. Harness the power of this essential amino acid for overall health and well-being. Among its potential health benefits, lysine supplementation has been shown to increase calcium absorption and retention.

L-Lysine Benefits

  • Supports healthy nitrogen balance
  • Promotes healthy calcium metabolism
  • Encourages a healthy stress response
  • Helps inhibit glycation
  • Fight Against Age-Related Factors
  • Lysine is an essential amino acid necessary for growth, and it helps maintain nitrogen balance in the body. It also appears to inhibit glycation, a biochemical reaction that can contribute to a variety of age-related factors. Glycation events disrupt the normal function of protein and lipid structures in the body and are accelerated by elevated levels of sugar in the blood.

Product Details
Most people consume adequate amounts of lysine, but vegan diets need to include beans and lentils in order to provide enough.1 Athletes involved in frequent vigorous exercise have an increased need for essential amino acids, and vegan athletes face the greatest challenge in getting the right balance and amounts of dietary amino acids.

Lysine supplementation has been shown to support healthy calcium metabolism, which may impact bone and vascular health.Additionally, its protective effects against glycation have been demonstrated specifically in the eye’s lens.

Lysine works with other essential amino acids to maintain growth, lean body mass and the body’s store of nitrogen. In addition, dietary supplementation with the essential amino acid L-lysine has been shown to encourage a healthy stress response in humans with low dietary intake of L-lysine and, together with arginine, normalize hormonal stress responses in healthy adults.
